GET /v1/health encoded apihealth.APIReply through jsonv2, which has no default representation for time.Duration — and every Result carries one. The marshal therefore failed on every node, every time, and the handler fell back to {"healthy":…,"error":"health reply encode failed"}. The status code is written before the encode, so k8s probes and dashboards stayed green while the body carried no checks at all. Measured on Zoo, Hanzo and Pars mainnet, node v1.34.9 and v1.36.2 alike. The type is defined with encoding/json tags and the POST (jsonrpc) path already encodes it through that codec, which is why POST returned the full check set while GET returned nothing. One wire type deserves one encoder: GET now uses encoding/json too, so the two paths agree by construction. encoding/json also maps invalid UTF-8 in check Details to U+FFFD instead of failing, which is the behaviour the old jsontext AllowInvalidUTF8 option was reaching for. The buffer stays: it keeps a partial encode from shipping a torn body. /v1/metrics answered 200 with zero bytes for the same shape of reason. luxfi/metric resolves NewRegistry() to a no-op registry unless the binary is built with -tags metrics (registry_noop.go, //go:build !metrics), and only the `full` profile passed it. Images build with the default `minimal` profile, so every metric in luxd registered into a black hole while --api-metrics-enabled=true still advertised metrics as on. Whether metrics are served is the runtime flag's call; a build tag must not silently overrule it. `metrics` becomes a base tag on every profile. Verified: the three new handler tests fail against the jsonv2 encoder (checks decode empty, error field nil — the exact production symptom) and pass after. `go tool nm` shows (*registry).Gather absent from a default build and present once the tag is set.

Adds the invariant as a test over every network's built genesis, and picks up luxfi/genesis v1.16.4 where the policies are sized to fit (3-of-5 on mainnet/testnet/devnet, 2-of-3 on localnet).

The plugin registry resolves a CreateChainTx's vmID to an implementation by filename, so the two never met: M-Chain was declared in genesis and no node could start it. The Dockerfile comment had already been renamed to "mpcvm" without the CB58 being recomputed, which is why it read as correct. Fixes all five sites (plugin build target, the build-verify list, the runtime COPY, the comment, and publish_plugin_set.sh) and adds genesis/builder/mchain_test.go, which pins the vmID literally and asserts M-Chain is present in the height-0 chain set for mainnet, testnet and local. A vmID is an immutable one-way door once a chain is created with it, so it is now covered by a test rather than by five copies of a string. Bumps luxfi/genesis to v1.16.3, where mchain.json states its quorum as "policy": "7-of-10" instead of a bare mpcThreshold that reads as the signer count to an operator and as the polynomial degree to a library.

The fetch pointed at luxcpp/cevm v0.19.0, which does not exist — the libs publish from the private lux-private/cevm repo, and unauthenticated downloads 404 there. Point it at v0.51.10 in that repo and authenticate with the same `ghtok` secret the private go modules and lux-accel already use. It stays best-effort, so a build without the token behaves exactly as before. Separately, the C-Chain plugin builds with CGO_ENABLED=0 and no tags, so it is always the pure-Go EVM regardless of what luxd itself links — which is why production images carry no cevm at all. That build now honours EVM_CGO and EVM_TAGS, defaulting to today exact behaviour; EVM_CGO=1 EVM_TAGS=cevm is what makes AutoEVM resolve to CppEVM. The libraries are already in this stage (the plugin section shares the builder stage rather than starting a new FROM). Defaults unchanged, so the in-flight v1.36.12 fleet build is byte-identical.

Before StartTracking (bootstrap churn) and for non-validator peers the flush is a no-op, so the prior unconditional Commit was an empty full-write+fsync on every such disconnect. Skipping it is correct: every writer under stateLock commits its own diff, so no orphaned write depends on the disconnect path.

The uptime tracker itself (vms/platformvm/uptime_tracker.go) is RED-cleared and UNCHANGED. CRITICAL #2 — P-chain state race (concurrent map writes -> fatal): chainRouter dispatched Connected/Disconnected on the peer-lifecycle goroutine, where VM.Disconnected -> tracker.Disconnect (state.SetUptime) + state.Commit (state.write) ran concurrently with the block acceptor's state.CommitBatch (state.write) on the engine accept goroutine — no shared lock, so ordinary peer churn triggered Go "concurrent map writes" and crashed the P-chain node. Fix: one VM-owned stateLock serializes every commit of shared platform state that originates outside the engine's lock-free VM.Accept call-out — - block DECISION: block/executor Block.Accept/Reject hold &vm.stateLock (supplied to executor.NewManager) around the whole acceptor visit; - peer/lifecycle: VM.Disconnected and the onReady/onBootstrapStarted/Shutdown Start/StopTracking uptime flushes hold vm.stateLock. This is avalanchego's ctx.Lock invariant (accept serialized with engine.Connected/Disconnected), scoped to the state the platform VM owns and implemented at the VM: the Lux engine invokes VM.Accept as a lock-free call-out (no ctx.Lock over accept exists) and a chain-agnostic blockHandler cannot reach a per-VM accept lock, so routing "through the engine" is not feasible. CRITICAL #1 — C-Chain nil-version panic on state sync: blockHandler.Connected passed connector.Connected(ctx, nodeID, nil). proposervm promotes Connected to coreth, whose state-sync peer tracker compares peer versions; a nil version deref panics any C-Chain node running state sync (a fresh join OR a validator rejoining after falling behind — the launch's core invariant). Fix: plumb the REAL peer version through a versionedConnector capability — chainRouter.Connected converts the node peer version (luxfi/node/version) to the VM boundary type (luxfi/version = chain.VersionInfo) and delivers it via blockHandler.ConnectedWithVersion -> connector.Connected. Audit: geth in-process Connected is a no-op stub (nil-safe); xvm stores the pointer without deref (nil-safe); the real coreth plugin derefs -> fixed by feeding the real version. Tests (SDKROOT + CGO_ENABLED=1, -race): - vms/platformvm/uptime_state_race_test.go: state.Commit (VM.Disconnected path) concurrent with state.CommitBatch (acceptor path) under the shared lock — no race/fatal; verified meaningful (an unlocked probe trips DATA RACE). - chains/blockhandler_connected_version_test.go + node/chain_router_connected_version_test.go: the real, converted version reaches the connector non-nil (dedup covered). Uptime tracker 13/13 and the block/executor reward gate untouched and green; go build ./... and go vet clean.

Root causes (four, all fixed): 1. StartTracking never existed/called. The custom uptimeTracker was created late (onReady) and never baselined validator records, so a long-running validator's stored upDuration stayed 0 and CalculateUptimePercentFrom returned 0/total = 0. 2. upDuration flushed only on Disconnect/Shutdown, so a continuously-connected validator's persisted uptime never grew. 3. service.go left `connected` hard-nil ("IsConnected no longer exists"). 4. ROOT: VM.Connected never fired. network.Connected -> chainRouter.Connected only added to a connectedPeers set and logged; it never dispatched to chain handlers, and blockHandler.Connected was a no-op. So tracker.Connect was never called and the connected map was always empty — nothing to accrue. Fix (faithful port of avalanchego snow/uptime.Manager semantics, luxfi pkgs): - vms/platformvm/uptime_tracker.go: rewrite as a startedTracking-gated tracker. StartTracking/StopTracking/StartedTracking/IsConnected added; CalculateUptime folds the live connected session forward to now using the persisted lastUpdated (reconstructed from the second-granular uptime.State encoding), so a connected validator accrues uptime WITHOUT a Disconnect. Before tracking, a validator is assumed online since its last update (avalanchego baseline); after tracking, only genuine sessions accrue. Second-granular clock matches storage. CalculateUptimePercentFrom is the clean upDuration/(now-from) form, clamped to [0,1]. - vms/platformvm/vm.go: create+register the tracker at Initialize (so bootstrap Connect events are captured), StartTracking(primary validators) at onReady, StopTracking on re-bootstrap and Shutdown. Mirrors avalanchego's onNormalOperationsStarted lifecycle. - vms/platformvm/service.go: populate `connected` via tracker.IsConnected. - node/chain_router.go: chainRouter.Connected/Disconnected now dispatch to every registered chain handler (snapshot under lock, call outside). - chains/manager.go: blockHandler forwards Connected/Disconnected to its chain's VM (engineVM) exactly once (dedup set), so the P-chain uptime tracker — and every VM's peer set — finally observes connectivity. Consensus safety: prefersCommit is a per-node PREFERENCE feeding oracle-block voting, not a deterministic value. Fixing the local uptime measurement (which was uniformly 0) changes only which reward option each node prefers; consensus still converges by preference voting. No staking/reward math changed. Tests (vms/platformvm/uptime_tracker_test.go, -race green): - TestUptimeTrackerLongRunningValidatorAccruesUptime: a 30-day validator reports ~100%. Uses only the shared Calculator API; run against the OLD tracker it returns 0.0 (FAIL — the exact mainnet symptom), against the fix 1.0 (PASS). - Continuously-connected-climbs, StartTracking-baselines, flush-on-disconnect, never-connected-gets-zero, StopTracking-flushes, idempotent double-connect, dedup, concurrency. block/executor (reward gate) suite green. Follow-on (NOT in this commit): devnet 5-node uptime-climb verification -> gated release -> owner-gated one-at-a-time mainnet roll. No image built, no deploy, no live validator touched.

Also unifies consensus's transitive geth pin to v1.20.1, matching node/evm (v1.36.9). The new PreferenceReconciler VM interface is optional, so node's VMs are unaffected (they take the non-fatal defer path); no code change required here. - chains v1.7.7 → v1.7.9: every VM (aivm/keyvm/quantumvm/dexvm) now serializes through native luxfi/zap struct-is-wire, with canonical-id hardening. go.mod/go.sum only — dependency-graph resolution, no node code change.

Store timestamp.UnixMilli() and read time.UnixMilli() so sub-second timestamps round-trip and build/verify agree on the slot. Measured at a 100ms window: errUnexpectedProposer frequent→0, 108→149 TPS, 2.8s→2.2s cadence, 5/5 byte-identical. Forward-only wire change (the outer proposervm timestamp; the inner EVM block timestamp is independent). Remaining sub-second floor is now the EVM targetBlockRate, not the proposervm.

MinBlkDelay was hardcoded to the 1s DefaultMinBlockDelay in chains/manager.go, ignoring its own --proposervm-min-block-delay flag. Now wired node.Config → ManagerConfig → proposervm.Config (0 ⇒ 1s default). High-throughput nets set it low. 2. Block timestamps were Truncate(time.Second) at 4 sites, quantizing cadence to 1s regardless of WindowDuration — so a sub-second window inflated slot numbers without finer time resolution and could NOT produce blocks faster than 1/s. Truncation now tracks proposer.TimestampGranularity() = min(1s, WindowDuration): mainnet (>=1s) keeps exact 1-second block times; sub-second windows get matching sub-second timestamps. Measured: 1s window/delay → ~95-104 TPS, byte-identical 5/5 finality (unchanged from before, no regression). NOTE: true sub-second cadence additionally requires a slot-handoff fix — at 100ms the slot recomputed in buildChild from a drifted 'now' can differ from the slot timeToBuild scheduled, causing errUnexpectedProposer verify drops; that + multi-sender saturation is the next step. These knobs are the necessary foundation.

CADENCE — proposer.WindowDuration (the proposer-slot spacing, a validator's min build delay = slot index x WindowDuration) was a hardcoded 5s const tuned for mainnet-scale validator sets, flooring small/local block cadence at 5s per slot. It is now a startup-configurable var (default 5s, unchanged for mainnet) set via the new --proposervm-window-duration flag → node.Config → ManagerConfig → proposervm.Config → proposer.SetWindowDuration at VM init. Read by both the windower delay math and TimeToSlot, so they stay consistent. Measured on a 5-node strict-PQ net: 5s→1s took sustained C-Chain from 44 TPS / 14s-per-block to 104 TPS / 3.8s-per-block, still 5/5 byte-identical finality. 2. SECURITY (cryptographer MEDIUM-1) — postForkCommonComponents.Verify now refuses a block carrying a CLASSICAL secp256k1 proposer identity when the chain is strict-PQ (StakingMLDSASigner set), UNCONDITIONALLY (before the consensusState==Ready gate, so it also holds during bootstrap/state-sync). Fills the documented-but-unwired 'proposer' SchemeGate site: the downgrade defense is now an explicit fail-closed in-perimeter gate, not merely emergent from 20-byte NodeID collision-resistance + upstream enforcement. Adds SignedBlock.HasClassicalProposer(). Mirrors contract.RefuseUnderStrictPQ. Pins consensus v1.36.7 (consume-on-error build loop — kills the non-leader BuildBlock spin).

But proposervm signed post-fork blocks with the classical TLS leaf and derived the block Proposer() via ids.NodeIDFromCert — a different value than DeriveMLDSA — so every signed block (height ≥ 2) failed verifyPostDurangoBlockDelay with errUnexpectedProposer, was dropped, and rebuilt in an unbounded storm (block 1 survived only because the unsigned transition block skips the proposer comparison). The block's offCert slot now carries a scheme-tagged proposer identity [scheme:1B|identity]: 0x90 classical (cert DER → NodeIDFromCert, ECDSA verify) or 0x42 strict-PQ (raw ML-DSA-65 pubkey → DeriveMLDSA(ids.Empty,pub), ML-DSA verify). ML-DSA signing/verification uses a FIPS 204 §5.2 domain-separation context ('lux-proposervm-block-v1') so a proposer signature can never be replayed as another ML-DSA message. proposervm.Config gains StakingMLDSASigner /StakingMLDSAPub, plumbed from StakingConfig through ManagerConfig; exactly one scheme is active per chain. K=1 nets are unaffected (transition + no-window blocks are unsigned). Proven on a 5-node strict-PQ local net: sustained multi-block production, every block built once, gossiped, and finalized byte-identical on all 5 (no automine). Pins consensus v1.36.6 (engine logger + logged build-drops) which made this diagnosable.

A cold coreth 'Regenerate historical state' pass after an unclean shutdown takes 67-134s on the mainnet C-Chain, blowing that budget → context cancelled mid-init → VM marked failed → C-Chain route never registered → the recurring post-restart 404 that required a second restart to clear. One named bounded constant (10m) covers regen with margin while still surfacing a truly-hung VM. Stop stays 10s. This is the third stacked restart-fragility bug after skip-bootstrap frontier (v1.36.11) and rejoin discriminator (v1.36.13).

Verified on devnet v1.36.12: C-Chain wedged at height 0 ('using empty beacons for single-node mode'). Fix: discriminate on the VALIDATING NET (chainParams.ChainID == PrimaryNetworkID) via new chainValidatesOnPrimaryNetwork — PrimaryNetworkID for C/X/Q, the sovereign net ID for L2s. C/X/Q now keep staked beacons under --skip-bootstrap (peer-sync a behind validator); L2s keep the empty-beacon single-node path. New regression TestChainValidatesOnPrimaryNetwork_RealHashChainID exercises the real discriminator with hash IDs; TestRED_EmptyStakedSetFailsSafe still green (forged-frontier gate intact).

The node decodes that field; the stale plugins never encode it, so vms/rpcchainvm/zap/client.go fails every EVM VM Initialize with 'zap decode initialize response: unexpected EOF'. Native VMs (P/X/Q) are unaffected; every EVM chain (C, D, and the L2 EVMs) fails to boot. Verified on devnet (published v1.36.11 digest c3cf92a6): P/X re-bootstrap fine, C+D deterministically EOF. Fix (image-only; node source unchanged beyond the version bump): - EVM_VERSION v1.104.8 -> v1.104.9 (api v1.0.15 -> v1.0.16, indirect via luxfi/vm) - force luxfi/api@v1.0.16 in the dexvm build stage (no dex release pins v1.0.16 yet) - CHAINS_REF v1.7.6 already carries api v1.0.16 (the other 10 VMs were fine) The api bump is code-free for plugins (chains v1.7.4->v1.7.5 adopted it go.mod-only).

Root cause: buildChain computed the bootstrap frontier-sync discriminator as `expectsStakedBeacons := !m.SkipBootstrap && native && !platform` AND emptied the beacon set whenever `m.SkipBootstrap`. Production validators hardcode --skip-bootstrap=true (to skip the initial bootstrap WAIT), so a real multi- validator native chain (C/X/Q) got expectsStakedBeacons=false + EMPTY beacons. FrontierTip then reported FrontierNoBeacons ("nothing to sync to"), the node named its STALE local last-accepted the network frontier, transitioned the VM to normal operation there, and never fetched the gap from its 4 healthy peers — the wedge survived every restart because --skip-bootstrap is persistent config. The entire peer-sync/self-heal machinery (bootstrap_sync.go) was dead code under skip-bootstrap. Fix: drive the discriminator from SYBIL PROTECTION (the true "real staked network" signal, already wired into ManagerConfig), not --skip-bootstrap. A sybil-protected native non-platform chain now keeps its staked beacon set and expectsStakedBeacons even under --skip-bootstrap, so a behind validator always catches up from peers. A genuine single-node / dev net runs sybil-protection OFF and still takes the empty-beacon immediate-start path. A single-VALIDATOR staked net (self-only set) is handled by a new FrontierTip hasExternalBeacons rule (placed after the P-ready gate), so it immediate-starts without a Connecting hang while a >=2 set runs the quorum. This matches the proven live remediation (flipping skip-bootstrap=false via the .allow-bootstrap marker caught luxd-0 up to tip in ~90s) and preserves every RED safety invariant (empty staked set still fails safe — TestRED_EmptyStakedSetFailsSafe). Tests: TestChainExpectsStakedBeacons_SybilDrivesNotSkipBootstrap, TestNodeBootstrap_SelfOnlyStakedSet_ReportsNoBeacons, and the headline TestNodeBootstrap_BehindValidator_StakedSet_CatchesUpNoWipe (N-blocks-behind → restart → catches up from peers to tip, no wipe).

So the runtime 'which fx owns this value' dispatch needs no reflection: it is a total match on the variant tag. Replaced reflect.TypeOf(val) + map[reflect.Type]int with: - fxKindOf(val): a Go type switch over the closed set of fx primitive types (compiler-checked exhaustive; lowers to a jump on the interface type tag), returning the value's wire.TypeKind — the same family tag the wire envelope already carries. - FxIndex: a dense [16]int array indexed by that TypeKind (one bounds-checked load; -1 = unregistered), filled by the SAME fx.(type) switch NewCustomParser already ran — no separate reflect registration. getFx (semantic verifier + tx_init) is now fxKindOf → array index: zero reflect, zero map-hash, compile-time-checked. Deleted registerFxTypes + all map[reflect.Type]int fields/params (parser, block/parser, vm, backend). Node-only (uses already-imported utxo fx types + wire.TypeKind); no dep cascade.

Fix: inject 'replace github.com/luxfi/node => /build' (the exact vX.Y.Z node source being built) into every /tmp/chains go.mod before building. This is what the existing 'plugins in lockstep with the host node' intent actually requires — the baked plugins now match the node they run in instead of an ancient pin. chains is the main module during the plugin build, so node(/build)'s own require of chains resolves back to /tmp/chains (main-module-wins) — no version fetch, no loop.

This is the gate before the Nova re-genesis: one write path, one read path, no version dispatch. Removed the whole multi-version surface: - txs: registerV0TxTypes, CodecVersionV0/V1/V2, CodecVersionForTimestamp, CodecForTimestamp, CodecAllowsRead, CodecRequiresLegacy, the Version alias, and codec_activation.go (ZAPCodecActivationTimestamp). - block: v0Codec/v0GenesisCodec, the block/v0 package, the lift_v0 path; Parse is now single-version. - state: the v0-probe codec_helpers (it Marshal'd at version 0, which would fire a false warning every boot); GenesisCodec.Unmarshal inlined. - genesis: single-version alias + comment cleanup. - warp/bench/network: stale "linearcodec"/"reflectcodec" comments corrected (all already ride the ZAP-backed pcodecs shim; wire unchanged). - wallet/chain/p: txs.Version -> txs.CodecVersion. Value 1 is retained (not renumbered) so no tx ID, block ID, or state root changes: the surviving codec is exactly the ZAP-native slot the chain already writes. Every existing serialization golden stays byte-for-byte. Determinism proof (codec_zap_test.go, block/codec_determinism_test.go): golden tx/block bytes + IDs, marshal idempotency, round-trip byte-stability for every tx and block type, and trailing/truncated/wrong-version rejection. grep -rnE 'linearcodec|reflectcodec|CodecVersion(ForTimestamp|V0|V1)' vms/platformvm/ is empty.

The manager's capability assert therefore returned !ok in production, the QuasarObserver stayed nil, and finalized/safe + the warp export gate stuck at genesis. Nova consensus was unaffected (node-side). rpcchainvm/zap client (*Client): - SetLastQuasarFinalized / LastQuasarHeight: ZAP-call the plugin (Msg 60/61). Both short-circuit if the plugin did not advertise CapQuasarExport, so wiring them is harmless for a generic plugin (no per-finalization no-op RPC). - SupportsQuasarExport: reports the capability captured (atomically, once) from the Initialize handshake's InitializeResponse.Capabilities. - Fire-and-forget Set (logged, not returned — the caller is the consensus observer); Height returns 0 on any failure (boot re-seed treats it as empty). chains/manager createChain: - quasarExportVM interface (values-not-places: the capability is a value, not a static type property). Gate the observer + boot re-seed on the capability: a *Client reports it via SupportsQuasarExport (false → Nova-only, exactly the old !ok semantics — no cross-process spam); a VM WITHOUT the probe (an in-process VM whose concrete methods we hold directly) is treated as capable, preserving the direct-wire path. Observer is set BEFORE NewRuntime captures netCfg; the seed runs after, carried by the exportVM value. Test (client_quasar_test.go, -race): the REAL cross-process path — node *Client -> ZAP wire -> luxfi/vm/rpc server -> a fake VM that satisfies the SAME capability interface as *evm.VM. Capability captured from the handshake; a pushed height crosses the wire into the VM; the VM's height round-trips back; a non-capable plugin is a graceful Nova-only no-op.

An L1 spawn is a BLOCK of CreateNetworkTx + N CreateChainTx (block-atomic, not tx-atomic). - Removed NetworkChain, its wire (writeNetworkChains/readNetworkChains/ ncStride/sliceIDs), the chain error set, MaxNetworkChains, the chains param. - managerChainIdx (index into genesis chains) -> managerChainID (direct ids.ID), now SYMMETRIC with ConvertNetworkTx's manager ref. ids.Empty => P-Chain-governed; a set chainID => Contract-governed staking-contract host.

GetContext (the catch-up "context response", wire = Ancestors) bounded the response ONLY by block COUNT (maxContextBlocks=256). Under heavy DEX load 256 blocks summed to 3.4-5.7 MB, exceeding the 2 MB peer message cap (the zstd compressor refuses uncompressed input above constants.DefaultMaxMessageSize to prevent a decompression bomb), so msgCreator.Ancestors FAILED to build and the behind validator received NOTHING — permanently stuck while the tip advanced (luxd-3 stuck at 256 while tip went 293→300, looping empty-block builds). Fix (piece 1/3 of the layered design — defense in depth): GetContext now ALSO bounds the response by serialized SIZE. It stops adding blocks before the accumulated payload would exceed byteBudget (cap − 128 KiB envelope margin), but ALWAYS includes at least one block so a behind node makes progress every round; the requester re-requests the remaining gap (context fetch is already a multi-round oldest-first fill). A single block that alone exceeds the budget is still served (best-effort) so the walk never deadlocks — the forthcoming trust-tiered validator cap (pieces 2/3) gives such a block the send headroom; a stranger's tight cap correctly rejects it. Tests (chains/context_chunk_test.go): TestGetContext_ChunksBySize_FitsUnderCap (100×150 KiB chain → 12 blocks / 1.84 MB, under budget, vs ~15 MB packed by count — fail-on-old); TestGetContext_SingleOversizeBlock_StillServed (one oversize block still served, no deadlock). Pieces 2/3 to follow: trust-tiered message cap (validator peers get headroom, strangers keep 2 MB) + confirm the inbound throttler/benchlist penalizes oversized-message senders.

The node-layer fetch machinery (networkCatchup.RequestAncestors -> requestContext -> GetAncestors -> AcceptCatchupBlock) was already fully wired — it was just never called on this path. With --skip-bootstrap=true (which disables the beacon-quorum frontier backstop) this cert-trigger was the ONLY self-heal path, so its absence was fatal: a behind node couldn't rejoin -> effective 4/5 -> any flap -> stall. Consensus-side only, no node code change. -race: launch-gate invariant PASS (rejoin 2.75s, no fork); self-heal + typed-error tests PASS, no data races.

Signed wire = unsigned_zap_buffer ‖ creds_zap_buffer (ZAP buffers are self-delimiting), preserving tx.go's unsigned-is-prefix-of-signed invariant with no tx.go change. AdvanceTimeTx + RewardValidatorTx bridged and round-trip green (build->Marshal->Unmarshal field equality, byte-stable, prefix invariant, non-ZAP reject).

Full engine/chain green (356s, 0 fail); -race clean; RED safety gate proves divergent inners still refused.

Root cause (consensus-layer, proven): under pChainHeight=0 anyone-can-propose, each validator wraps the same inner block in its own outer proposervm envelope; votes are canonical-keyed so an α-of-K cert forms network-wide, but HandleIncomingCert did a strict envelope-id lookup — a node holding a different alias of the same inner block missed it and requested catchup instead of finalizing the local wrapper it held, so VM.Accept was never called and the EVM head froze at 1085755 while consensus logged 'finalized voters=4'. v1.35.34 (66438a23b) resolves the local wrapper by canonical id and rebases the verified cert (outer ids unsigned; α votes verify unchanged), no fork (per-height gate keys on canonical id, idempotent). Also: dynamic committee 1→N proven (v1.35.35, effectiveCommittee sizes cert + view-change from live validator count; n=1→1/1,2→2/2,3→3/3,4→3/4,5→4/5 — the BFT-safe ⌊2n/3⌋+1); view-change safety gate realigned to the effective committee (RED#2); snowman comment-purge (Quasar/Nova); dynamic committee logs.

The consensus engine's ledger advancing on VM.Accept is proven in engine/chain; this proves the OTHER half at the NODE layer — that VM.Accept on a proposervm wrapper cascades to the inner block's Accept: postForkBlock.Accept → acceptOuterBlk → acceptInnerBlk → Tree.Accept(innerBlk) → innerBlk.Accept ⇒ inner VM lastAccepted advances - TestAcceptCascade_InnerHeadAdvances_AtScale: 1000 heights through the REAL Accept path; the inner EVM head + proposervm head advance in lock-step at every height. - TestAcceptCascade_SiblingStorm_WinnerAdvancesInnerOnce: five distinct outer envelopes wrap ONE inner block (the anyone-can-propose alias set); accepting the finalized wrapper advances the shared inner exactly once. Confirms the propagation was sound, not a node-layer bug — the freeze was the consensus-layer storm-alias resolution gap (fixed in consensus v1.35.34). The real luxfi/evm RLP-import→produce →tip byte-exactness is proven separately in evm/core rlp_seam_red_test.go; composed, they cover the full engine→proposervm→EVM Accept path.

Build-side companion to the defect #1 SetPreference validate-before- assign hardening. vm.preferred is only adopted after a successful getBlock, but a block fetchable at preference time can later become unfetchable: an unaccepted sibling consensus dropped, or a never-persisted outer block referenced after heavy sibling churn. The old BuildBlock returned after the single getBlock(preferred) miss with "failed to fetch preferred block", so every attempt failed in a tight loop and the node's voter went mute (~170 err/s). Quasar cert-finality has no re-converge poll, so the fleet never recovered on its own — the liveness wedge behind the mainnet 1082879->1085755 window (heartbeat-pause + full-fleet-restart churn). Fix: on an unfetchable preferred, build the child on last-accepted (always held: committed state). The node keeps producing on a valid tip while the catch-up path pulls the gap; a later SetPreference(held tip) re-advances the preference. Only surface the original error when last-accepted is itself the unfetchable id. Tests (hermetic, mirror vm_rejoin_wedge_test.go): spy inner VM asserts the fetch sequence — BuildBlock consults last-accepted on an unheld preferred (old code never did), and does not spuriously fetch when no distinct fallback exists.

Two node-layer defects, both BFT-safe (compared against ava avalanchego proposervm): #1 proposervm.SetPreference (vms/proposervm/vm.go): assigned vm.preferred BEFORE fetching, so a build-tip the node doesn't hold POISONED vm.preferred forever (BuildBlock errors on every attempt; Quasar cert-finality has no re-converge poll). Now: getBlock (both post-fork + inner stores) FIRST, delegate to inner, adopt the preference only on success; on a total miss keep the last held tip and stay live. Identical to ava in every case its single-store invariant produces; only adds recovery for Lux's build-tip steering (never bricks). SetPreference is not an acceptance gate, so safety/agreement is untouched. #3 peer selection (chains/manager.go): consensus signals "fetch a certified-but- untracked block" via ids.EmptyNodeID; the old code Add(EmptyNodeID)+Send, so GetAncestors went to ZERO peers and the cert-verified gap was never fetched. Now: when nodeID is Empty, sample real connected peers that track this chain's network (same selection pollFrontierOnce uses); the cert already gated the ask. Adds vm_rejoin_wedge_test.go. (Defect #2 — the engine build-tip steering in consensus/engine/chain — is the upstream root cause, tracked separately.)

That is an unbounded, ever-growing sibling set at one height: the round-scoped view-change can never gather α aligned prevotes on a single candidate (no proof-of-lock forms) and finality stalls fleet-wide (the distributed liveness stall). Snap the child timestamp DOWN to the parent-anchored proposer-window grid (parentTimestamp + slot*WindowDuration, slot = TimeToSlot(parent, now)) so all rebuilds WITHIN one slot are byte-identical → one stable candidate the view-change converges on. Safe by construction: TimeToSlot(parent, snapped) == slot == TimeToSlot(parent, now), so the block's slot — hence ExpectedProposer's proposer-window / signed-unsigned verdict and the derived epoch — is unchanged. Only slot>0 snapped, so a fresh in-window child keeps its exact timestamp (zero live-chain change), and a snapped time is strictly > parent (monotonic) and <= now (not advanced). Liveness-only; no safety surface touched. Extracted as slotSnappedChildTimestamp + unit-proven (idempotence, slot-invariance, monotonicity). Full proposervm suite green.

Consensus engine untouched (v1.35.5 boot-seed from v1.32.10 carried forward). [HIGH — correctness] info.isBootstrapped(C) tracks REAL state, not premature true. manager.IsBootstrapped(id) returned true the instant a chain merely EXISTED in m.chains (set right after createChain launched the async, possibly-stalling bootstrap goroutine) — so a C-Chain stalled at genesis (head 0x0) reported info.isBootstrapped(C)=true, masking the stall from any wait-for-healthy gate. Now keys on the SAME sb.Bootstrapped signal the readiness health check uses (m.Nets.IsChainBootstrapped), set only after runInitialSync reaches the named frontier and the VM goes to normal operation (head advanced, eth-RPC live). GetChains().Bootstrapped fixed identically. New per-chain query on nets.Net + chains.Nets (nil-safe). Regression test TestIsBootstrappedTracksRealConvergence. [MEDIUM — robustness] WIPE-path GetAncestors fetch hardened for ≥2 peers at genesis. Applying the proven avalanchego contract (studied in snowman/bootstrap + getter): (a) Ancestors buffers the whole sample and SKIPS empty batches, returning the first NON-EMPTY one — a size-1 channel let a fast empty reply from a genesis peer win the race and starve a peer that actually held the ancestry; (b) sampleAncestorBeacons PREFERS beacons the frontier round found genuinely ahead (they hold the ancestry) — ava's PeerTracker "ask a prover" bias sourced from the replies we already have, no separate tracker. Tests: TestNodeBootstrap_WipePath_MixedGenesisPeers_ObtainsAncestry, TestSampleAncestorBeacons_PrefersAheadBeacons. Build: main+chains+nets+service/info compile CGO_ENABLED=0 (ARC/Dockerfile path); full chains+nets suites green.

Sign-gate-only (never enters byHeight/ledger.Height; PART-A intact; only refuses more). Supersedes the un-rolled node v1.32.9 (consensus v1.35.4) for the mainnet-first roll.

This branch also EXCLUDES node-main's /ext->/v1 route migration to keep the incident recovery minimal and avoid breaking /ext/bc/C/rpc tooling mid-recovery. Recommended tag: node v1.33.1 (forward past the v1.33.0 revert-magnet so the image tooling cannot revert testnet to the disproven build).

This closes Red's HIGH-1 on the wire that matters: a signing validator's (height,epoch)→canonical bindings are fsync'd before it votes and reloaded on startup, so a crash between casting a vote and finalizing the height cannot forget the binding and let the restarted node sign a conflicting sibling — the cross-node fork with zero Byzantine intent under a rolling upgrade / eviction / OOM. The store is opened at the node boundary so the fail-closed-on-corrupt decision (a signer refusing to start with equivocation memory it cannot trust) lives here, not in the engine. luxd builds against pinned v1.33.3.

BUG 1 (HIGH) — concurrent-map crash in getPostForkBlock. The consensus engine drives the proposervm from multiple handler goroutines concurrently (a PullQuery/Put verifying a block WRITES verifiedBlocks via verifyAndRecordInnerBlk while a Qbit handler READS it via GetBlock -> getPostForkBlock; the retry loop in PullQuery even documents "allow concurrent Put to complete").

Fix: a dedicated verifiedBlocksLock (RWMutex) behind three accessors (cachedVerifiedBlock / recordVerifiedBlock / forgetVerifiedBlock) at ALL seven sites; the sibling Tree.nodes map (touched on the same Verify/Accept paths) gets its own RWMutex, with Accept restructured to make its inner-VM Accept/Reject callouts OUTSIDE the lock. Both are leaf locks, never nested, never held across a callout — the lock graph is a strict DAG (vm.lock > verifiedBlocksLock; tree.lock disjoint), so deadlock-free. innerBlkCache (lru.SizedCache) is already internally locked. Regression: TestVerifiedBlocksConcurrentAccess + TestTreeConcurrentAccess hammer readers vs writers under -race; both FAIL on the pre-fix code with the exact production signatures ("concurrent map read and map write" / "concurrent map writes") and pass after. BUG 3 — a proposervm height index BELOW the inner VM tip (the devnet-C "index 7 < inner 8" from a snapshot restored inconsistently across the proposervm and EVM databases) had a cryptic fatal ("should never be lower"). It is now a LOUD, ACTIONABLE fatal with a recovery runbook. It is deliberately NOT "self-healed" by dropping the finality pointer: after DeleteLastAccepted, proposervm.LastAccepted() falls back to the INNER-namespace id, whose ParentID is contiguity-incompatible with the network's OUTER wrappers — that permanently wedges bootstrap (first-block anchor), catch-up (parent==tip guard) and live Verify (parent lookup) at the inner tip (blocks at height <= tip are skipped, so the missing wrapper is never rebuilt): a SILENT wedge strictly worse than the loud stop. The only correct remedy is operator action (restore a consistent snapshot or full resync), which the error now states. The reconciliation decision is decomplected into a pure classifyHeightRepair(pro, inner) -> heightRelation, regression-locked by TestClassifyHeightRepair so a revert to a silent reset fails the test; the fork height is read lazily (only the ahead/rollback path needs it), so the match and behind paths gain no new failure mode. RED-reviewed: CHANGE 1 (locks) cleared (deadlock-free DAG, fail-on-old proven); the original bug-3 silent-reset was caught as a wedge and reworked to this fail-loud form.

Dormant default verified a true no-op; these harden the ACTIVATED path before any forward-dated activation: H1 (HIGH) — bindCheck now binds cert.Epoch == cp.Epoch (and cert.Round). The gate resolves verification keys from the cert's epoch; an unbound epoch let a cert signed under a DIFFERENT validator-set era (e.g. a compromised RETIRED committee key) certify the current block, nullifying KeyEra rotation as a blast-radius bound.

Removed time.Now() (and the ActivationConfig.Time field) from the accept path: wall-clock gating split finalization across validators with skewed clocks (some halting on a missing cert, others finalizing without one). A height is consensus-agreed; timestamp forward-dating is expressed by choosing the activation height.

This wires the verify half as an OPTIONAL, FORWARD-DATED, DORMANT-BY-DEFAULT check in the block-accept path. consensus/quasar (new package): - Gate.VerifyAccepted: the accept-path safety boundary. nil gate / zero activation / below-activation-height / non-checkpoint => no-op (classical Snow unchanged). Post-activation at a checkpoint => REQUIRE a valid cert bound to the finalized block; fail closed (missing/mismatch/invalid -> error). - ActivationConfig: forward-dated dormant switch (Height==0 => never; optional wall-clock Time gate). The safety contract: this branch changes NOTHING about live finality until the owner sets a real activation height. - bindCheck: anti-replay binding (cert chain/height/block/state == finalized). - policyStore: default posture HYBRID_PQ = Beam(BLS) ^ Pulsar (Pulsar verify ~140us < BLS, cert ~27KB); STRICT_DUAL_PQ / POLARIS configurable. The cert can never select its own (weaker) policy (I1/I2 enforced by consensus). - ValidatorSet/MemCertStore: the per-leg key + cert-lookup seams (HYBRID_PQ BLS+Pulsar keys now; Corona/Magnetar/weighted-set + per-epoch resolution are the activation-wiring follow-on). - Producer (scaffolding): the committee-sign service contract + MaybeProduce request site, sharing ONE checkpoint cadence with verify. nil producer = verify-only (the default). Concrete pulsard signer is the follow-on; it needs consensus to export the (currently package-private) cert/payload ENCODERS. proposervm: post_fork_block.Accept calls vm.verifyQuasarFinality(b) BEFORE the accept commits, so an un-PQ-certified checkpoint halts without persisting. nil gate (default) => unchanged classical accept.

The node is itself a beacon and knows its OWN accepted tip with certainty. Add the SELF-VOTE: in the below-floor case, when the node has reached its ENTIRE beacon set (fullyConnectedBeacons — no eclipse can hide an ahead-tip) and that full set PLUS itself unanimously hold a tip it has ALREADY ACCEPTED with nobody ahead, return the new chainbootstrap.FrontierCaughtUp -> the loop completes at the node's own tip. Safety (proven by tests): self is counted ONLY under FULL connectivity, so an eclipse suppressing any beacon breaks full-set and falls back to the partition-capture floor (fail safe) — self can never tip a PARTIAL view into a false caught-up (stale-go-live guard holds). AcceptsFrontier still tallies PEERS ONLY, so a behind node's ahead-frontier is named undiluted and it still syncs; a peer above our height defeats CaughtUp. self only vouches for its OWN accepted tip so C1 (forged-frontier naming) is untouched. - selfNodeID threaded from m.NodeID into the blockHandler. - helpers fullyConnectedBeacons + withSelfVote. - bump luxfi/consensus v1.29.0 -> v1.29.1 (FrontierCaughtUp status).

Four fixes: CRITICAL-2 (consensus v1.25.36→v1.25.37): the equivocation handler downgraded Logger.Crit→Error. The per-height guard already rejects the second conflicting cert (safety preserved); Crit→os.Exit converted a handled safety event into a fleet-wide liveness kill (every honest node that observed the gossiped cert exited) AND made the slashing-evidence loop dead code. Now: log Error, reject, record DoubleVote evidence, keep running. CRITICAL-1 (pre_fork_block.go + vm.go): window the pre-fork→post-fork TRANSITION block. It must stay unsigned (verifyPostForkChild rejects a signed transition), but WHO builds it is now gated by the windower's ExpectedProposer — only the elected leader builds the unsigned height-1/N+1 block; non-leaders drop it and adopt the gossiped block (timeToBuildPreForkTransitionLocked windows the wait). Without this, every validator built its own transition block stamped with its local wall-clock second → divergent height-1 blocks → fork at chain start. CRITICAL-3 (manager.go + config.go + vm.go): thread the resolved networkID into proposervm.Config and the windower (newWindower) instead of hardcoding PrimaryNetworkID. On a sovereign L1 (Zoo/Hanzo/Pars, networkID==chainID) the hardcoded primary set was empty → ErrAnyoneCanPropose → single-proposer silently did not hold. Resolved ONCE in manager.go so windower and cert side share the identical set. Fresh-chain init tolerance (vm.go): repairAcceptedChainByHeight returns nil when the inner last-accepted block is not retrievable (brand/feature VMs Q/A/G/K whose genesis references an empty parent → GetBlock 'not found' even though the ID is not ids.Empty).

Three subtle correctness gaps that left single-proposer NOT actually holding: CRITICAL-1 (pre-fork→post-fork transition): the FIRST post-fork block (which a fresh-genesis chain like devnet hits immediately) was forwarded to the inner VM and built by EVERY validator unconditionally — forking the chain at its very start. timeToBuildPreForkTransitionLocked now windows the transition block the same way post-fork blocks are windowed (MinDelayForProposer), so a non-leader waits its slot and adopts the elected leader's gossiped transition block; a down leader can't stall (the eligible set widens as the slot advances). CRITICAL-3 (validator-set ID): the windower hardcoded PrimaryNetworkID, so a sovereign L1 (Zoo/Hanzo/Pars, validators under their own networkID==chainID) got an EMPTY set → ErrAnyoneCanPropose → equivocation exactly like the unfixed C-Chain, AND diverged from the cert's set. config.NetworkID (resolved once in manager.go: primary for native, else the L1's chainID, fallback to primary if empty) now binds the windower to the SAME set the cert uses. Zero value (ids.Empty) IS PrimaryNetworkID, so native chains are byte-identical. newWindower encapsulates this. proposervm pkg + full luxd binary build clean; go vet clean (chains, proposervm). \@OCx3tree 4d1874158a9e8f5f947acdee477d831e2c5eeac9 parent 9b1b040aac584f33e0bc915e39a20d701640bc14 author zeekay 1782635198 -0700 committer zeekay 1782635198 -0700 proposervm: don't crash on a fresh inner chain (empty last-accepted) Deploying the proposervm re-wrap crash-looped the whole node on a fresh re-genesis: repairAcceptedChainByHeight read the inner VM's last-accepted as ids.Empty (some Lux VMs report the empty ID before their first acceptance) and called GetBlock(ids.Empty) → 'failed to get block 111...LpoYY: not found' → VM initialization failed → 'error creating required chain' → node exit(1). A fresh inner chain has no accepted chain to roll the proposervm height index back against, so there is nothing to repair.

Lux had commented out the proposervm wrapper and hand-rolled a WaitForEvent→toEngine bridge that dropped the single-proposer invariant: every validator's engine called BuildBlock UNCONDITIONALLY at every height off a slightly-different mempool, so two nodes could each gather an α-of-K cert for DIFFERENT blocks at the same height → reportCertEquivocation → Logger.Crit → crash (and the DEX-tx nondeterminism wedge). That, together with the evm builder-ready race (evm v1.99.51), is why every multi-validator C-Chain froze. Re-wrap multi-validator linear chains in proposervm so block production follows the Snowman++ proposer schedule — exactly ONE validator builds height H, the rest wait and vote. proposervm.WaitForEvent only returns PendingTxs inside THIS node's proposer window, collapsing the race at its source. Gated (all three): K>1 (single-proposer only matters for a quorum), not the P-Chain (its height-indexed validators.State is published during its own createChain, after the snapshot used here), not DAG-native (X-Chain's Linearize bridge doesn't compose with proposervm's pull/window model). Engine, WaitForEvent bridge, block handler, SetState, and HTTP registration all route through the wrapped engineVM; unwrapped chains keep the original path byte-for-byte. chains pkg builds + go vet clean.

A block built faster than parent.Time+TargetBlockRate has a higher required fee; a small-tip/legacy tx can't cover it, verifyBlockFee rejects it, stall. evm v1.99.51 fixes both (builderReady select + target-rate pacing, with a nextBuildTime pure helper + regression test). chains v1.4.8 rebuilds the C-Chain VM plugin against it.

The mocks injected the FULL, STABLE validator set from t=0 — masking the production trigger. ROOT CAUSE (primary). A native chain's runBootstrapThenPoll starts right after its VM.Initialize (dispatchChainCreator), NOT after the P-chain has finished its own initial sync. The P-chain populates m.Validators as it replays blocks (genesis stakers + every AddValidatorTx), so FrontierTip can run while GetMap(PrimaryNetworkID) is a PARTIAL set. The MinResponseWeight stake-majority floor (total/2+1) is fail-secure ONLY when `total` is the TRUE full-set stake; under a partial denominator a degenerate at-or-below responder subset (the genuinely-ahead producers not yet loaded) clears the floor and the exact-fast- path / CaughtUp concludes "caught up" at the stale local height. Proven by elimination: with the full set EVERY accurate-reply path is fail-safe (wait / sync), so the freeze requires a non-representative responder set. FIX (primary): gate a native non-platform chain's frontier-trust on the P-chain having COMPLETED initial sync (m.pChainBootstrapped, published by monitorBootstrap; read via blockHandler.primaryNetworkReady). Until then FrontierTip returns FrontierConnecting (WAIT), so every branch judges the TRUE full validator set and the existing floor logic holds. Deadlock-free: the P-chain converges independently from its own configured CustomBeacons. FIX (self-heal / the "ALSO FIX"): pollFrontierOnce filtered peers on b.chainID — the IDENTICAL chainID/networkID confusion already fixed in connectedBeacons. Peers advertise the NET they track, never an individual native chain id, so the sample was always empty and a behind-but-Ready validator never discovered it was behind. Filter on b.networkID so the NormalOp catch-up poller actually fires. INSTRUMENTATION: FrontierTip now logs (Debug) the full beacon-set size + total stake (the floor DENOMINATOR — a partial value is the smoking gun), connected count, and every reply's tip + locally-resolved height + held-or-not, plus the decision. Set the C-chain log level to Debug on the canary to capture ground truth. TESTS (production-modeling, not the ideal full set): TestRED_PartialStakedSet_ BehindNodeMustNotGoLiveStale reproduces the freeze (without the gate it NAMES the stale own tip; with it, WAITS; then converges on the full set) — proven load-bearing (disabling the gate fails the test). Plus not-held-tips → sync, empty-ancestry → stays Bootstrapping (never Ready stale), and peer-connect-delay → wait-then-converge. Full chains suite green (C1, co-restart, M1, mass-recovery, skewed-weight all preserved), race-clean. 04jx& tree d0d65f651c649b1ad9f2b31486a0af6c5f4dda7c parent 8e0815cf7bfd506b7d3101d0a64b7c0845d51b33 author zeekay 1782561579 -0700 committer zeekay 1782561579 -0700 fix(chains): close M1 eclipse-stale own-height naming — frontier names STRICTLY ABOVE last-accepted (red fast-follow) nameFrontier's ancestor-tolerant filter was `ref.Height < MinFrontierHeight` (MinFrontierHeight = the node's own last-accepted), so a block AT the node's own height passed the filter and could be NAMED. Red's M1 eclipse: with the genuinely-ahead responders throttled below the ⅔ naming threshold (R_a < ⅔R) but the at-height responders let through, the node's OWN height accrues ⅔ purely as the shared ANCESTOR of the ahead N+5 tips → nameFrontier names it → FrontierNamed at own height → the node goes Ready STALE (5 blocks behind a finalized N+5). nameFrontier ran BEFORE CaughtUp in FrontierTip, so it short-circuited the stricter CaughtUp determination that already refuses this. FIX (one operator): `ref.Height <= MinFrontierHeight` — own height is excluded from naming, routing the at-own-height case to CaughtUp, which alone distinguishes a legit all-at-N fleet (Ready at N) from an eclipse with ahead tips the node lacks (refuse → sync). The two paths compose with no gap: nameFrontier names STRICTLY ABOVE own height (behind nodes); CaughtUp decides at-or-below own height (tip-holders); the fast path (active ⅔-direct report) stays exempt for the legit unanimous-at-tip case. Safe for layer-5 + C1: a behind node names HIGHER than its own height (survives both the old `<` and new `<=`); the ⅔-of-responder-weight naming requirement is untouched (only height eligibility tightens — strictly safer). Round-1 behind-node convergence is unchanged. Faithful test correction (manager.go: GetAcceptedFrontier answers vm.LastAccepted — the last-ACCEPTED block, NEVER an un-finalized preferred tip): the two ancestor-tolerant convergence integration tests modeled a beacon reporting an un-finalized tip FOREVER (a gap-1 instance of this very M1 stale-go-live). They are restated to model finalization PROPAGATION — the node names the ⅔-common as a behind node, then RATCHETS to the true finalized tip as the laggards' accepted frontier advances — converging to the real frontier (stronger guarantee), never falsely caught-up below it. Tests (RED-before by reverting the one-operator hunk, GREEN-after): - TestBootstrapTrust_EclipseOwnHeightNotNamedRoutesToCaughtUp (policy, deterministic + own-height boundary) - TestRED_EclipseOwnHeightNotNamedRoutesToSync (integration: FrontierNoQuorum + full-loop fails safe at stale N + eclipse-lifts→syncs-up) GOWORK=off CGO_ENABLED=0 go test ./chains/ — all green (layer-5 convergence, C1 forged/eclipse/partition, caught-up co-restart, fast-path, self-heal). 6-xOtree 619a41aed5737a79f30c9166d167ecc7d79adb79 parent b313912413c5eb910d63442306590a5b2daa89a8 author zeekay 1782558133 -0700 committer zeekay 1782558133 -0700 fix(chains): caught-up go-live for tip-holders — close the co-restart freeze regression (RED CRITICAL) RED found a CRITICAL liveness regression in the VM-ready gate (b313912413): a tip-holding producer on a mixed-height co-restart cannot satisfy its own go-live gate and fails safe DOWN at its own tip — the OPPOSITE of the stale-go-live bug the gate fixed, and just as wrong. Mechanism (PoC reproduced): a producer at N sees its 4 peers split {2 producers@N, luxd-2@N-16, luxd-0@genesis}. The tip-holders are only ½ of the responders (< ⅔) so no frontier is NAMED; the ⅔-backed common ancestor N-16 is below the node's own last-accepted (MinFrontierHeight filters it). → ErrNoBeaconQuorum → runInitialSync false → C-Chain STOPPED. The loop's Has(tip)→caughtUp shortcut is only reached AFTER FrontierNamed, which a tip-holder never gets. PRIMARY FIX — a CAUGHT-UP determination (BootstrapPolicy.CaughtUp), the dual of AcceptsFrontier ("nobody is ahead" vs "here is the block ahead"). On the ErrNoBootstrapQuorum branch, FrontierTip concludes caught-up and names the node's OWN held tip (→ the loop's existing Has()-shortcut → Ready at own height) iff: (a) the SAME response floor AcceptsFrontier uses is met (MinResponses count AND MinResponseWeight stake-majority) — an eclipse hiding the ahead-nodes drops below the floor → fail safe, no partition-capture; (b) every responder's reported ACCEPTED tip is at height ≤ lastAccepted — a stale node has an honest responder ahead → still syncs (stale-go-live stays fixed); (c) the node HOLDS every reported tip (heightOf injected, VM-free) — never declares caught-up to a sibling/fork it lacks. floorMet + tallyResponders are extracted so naming and caught-up share ONE floor and ONE eligibility rule (DRY). No consensus change — reuses FrontierNamed + Has, builds GOWORK=off against the deployed consensus v1.25.35. SELF-HEAL (RED MEDIUM #2) — the K8s probes all poll the always-green /ext/health/liveness, so a fail-safe-DOWN node is NEVER restarted (a permanent brick). runInitialSync now RE-ATTEMPTS a transient connectivity fail-safe (bootstrapMaxAttempts ≤ 0 ⇒ until the quorum returns or shutdown), staying in Bootstrapping (never live at stale height) and converging the instant the quorum returns. bootstrapConnecting tells monitorBootstrap's no-progress watchdog this is a deliberate WAIT (not a stall) so it does not force-STOP a node correctly waiting for its quorum. Structural failures (deep gap → state-sync) are NOT retried. LOW — FinishBootstrap now runs BEFORE transitionVMReady (close the no-cert AcceptBootstrapBlock gate before the VM can build); transitionVMReady's SetState timeout is derived from the shutdown ctx (was context.Background()). MEDIUM — createDAG (X/Q) go-live left UNCONDITIONAL, now documented as a DELIBERATE linear-only scope (mainnet froze on linear C/D/B/T/Z; DAG bootstrap convergence is a separate task). createDAG does not regress. C1, VerifyWeighted, the ⅔-stake cert, and "no VerifiedQuorumCert no finality" are untouched. Tests (chains): TestRED_TipHolderCoRestartGoesReadyAtOwnTip reproduces the regression — RED before on b313912413 (FrontierNoQuorum, live==false), GREEN after (FrontierNamed at own tip, vmReady once at N). Plus 6 CaughtUp unit tests (incl. both adversarial fake-caught-up cases), TestRED_MajorityOutageSelfHealsWhenQuorumReturns, and TestWatchBootstrapProgress_ConnectingNotStalled.

The proper vm.Bootstrapping state (the EVM's onBootstrapStarted: snapshots only, no building) was skipped entirely. Fix — restore the correct VM lifecycle, gated: - buildChain now SetState(vm.Bootstrapping) after init (not Ready). The VM fetch+executes the gap in Bootstrapping, serving nothing as head. - The Ready transition moves into the bootstrap goroutine (runInitialSync, split out of runBootstrapThenPoll for unit-testability) and fires ONLY after bs.Run reaches the named ⅔-by-stake beacon frontier — VM live + engine cert-gate (FinishBootstrap) go together at the frontier, never at a stale height. Wired via blockHandler.vmReady (captures the VM's SetState). - Fresh-genesis / single-node (FrontierNoBeacons) and at-the-tip restart (caught-up) go Ready promptly — no regression, no hang. - Eclipse / isolation: bs.Run's bounded ConnectDeadline is the retry that self-heals when beacons return; past it the node fails SAFE (stays Bootstrapping, records the reason for monitorBootstrap) — never serves stale state, never an unbounded hang. The orchestrator restart now converges. C1 forged-chain defense, VerifyWeighted, and the ⅔-stake quorum cert are untouched — the frontier is still named only by the configured-beacon ⅔-of-responders quorum + content-addressed descent (all RED/BootstrapTrust tests pass). AcceptedFrontier/Ancestors replies route to the bootstrap channels via bsActive throughout the phase (verified). Tests (chains): TestRED_StaleValidatorGoesReadyOnlyAfterReachingFrontier reproduces the production scenario — RED before (VM goes live at stale N=30), GREEN after (only at frontier N+K=46). Plus fresh-genesis no-regression, bounded eclipse fail-safe, and at-the-tip producer fast-Ready. Race-clean. NOTE (flagged for review, NOT in this change): the createDAG path (X/Q DAG chains, consensusdag.Engine) has the same unconditional SetState(Ready) at manager.go:1792 but a different engine without the node-layer bootstrap-sync wiring — a separate fix if any production chain uses it.

The 2 stranded recovery targets ARE 2 of the 5; with them down only 3 producers connect = 1.5e18 = 60% < ⅔. The prior bootstrap frontier quorum required ⅔ of CURRENT TOTAL stake to be CONNECTED before naming a sync frontier — mathematically unsatisfiable during a mass outage when the down nodes are themselves validators — so no node could ever recover. Bootstrap trust was braided into consensus finality, and finality's ⅔ rule cannot be met when ⅓+ of the set is the thing recovering. THE FIX — a SEPARATE type with a SEPARATE threat model, not a renamed threshold (chains/bootstrap_trust.go): - ConsensusQuorum.HasFinality(weight,total): > ⅔ CURRENT stake — UNCHANGED; present only to NAME the live rule and CONTRAST it. - BootstrapTrust.AcceptsFrontier(ctx,replies): selects a weak-subjective sync anchor from authenticated CONFIGURED beacons. NOT a finality oracle. - BootstrapPolicy: TrustedBeacons (the configured/checkpoint/genesis anchor — never peer self-report), AgreementThreshold (⅔ of RESPONDERS), MinResponses (a response FLOOR), MinResponseWeight, Checkpoint (operator override). Three invariants: 1. NON-CIRCULAR eligibility — only NodeIDs in TrustedBeacons count; peers never define who is a beacon. 2. A response FLOOR prevents partition-capture — MinResponses (default: a MAJORITY of the configured set) authenticated beacons must respond; below it, REJECT unless an operator checkpoint is pinned. For the 5-validator mainnet (MinResponses=3) the 3 reachable producers recover while a 2-beacon partition is rejected. 3. Acceptance ≠ finality — the named Frontier is "safe to begin sync from", re-executed during descent; live acceptance stays governed by ConsensusQuorum alone. The acceptance gate (FrontierTip) now routes through BootstrapPolicy: the ⅔-of-CURRENT-TOTAL connect gate is GONE; agreement is ⅔ of the RESPONDERS over a MinResponses floor. The ancestor-tolerant common-ancestor tally is reused (now a global cross-anchor union tally so a sibling split converges to the shared committed block — case F), bounded below by MinFrontierHeight (the node's last-accepted height) so a fork sharing only history BELOW the node fails safe instead of false-completing at the deep ancestor. Consensus (v1.25.35) is UNTOUCHED — the FrontierStatus interface is unchanged and its engine/chain suite stays green. Tests (chains green; consensus engine/chain green): A mass-recovery success, B one-beacon capture rejected, C two-beacon partition rejected, D non-configured peer ignored, E minority-configured forgery rejected (forger ratifies the real block, never names its forgery), F split reachable ancestry selects the common ancestor, G finality unchanged (3-of-5 accepts for bootstrap but is NOT HasFinality). Plus checkpoint override and a load-bearing fork-at-shared-genesis fail-safe guard for the global tally. The reframed SubAlpha→SubQuorum test replaces the ⅔-of-total assertion that WAS the bug. Each guard proven load-bearing by revert: restore the ⅔-of-total gate and A deadlocks; drop the configured-beacon filter and D captures; drop MinFrontierHeight and the shared-genesis fork false-completes.

On a live chain validators are legitimately ±1 block apart at the bleeding edge, so the freshest tip splits and no single id draws ⅔. The mainnet canary (luxd-2): 2 producers had accepted block N, the third producer's un-finalized PENDING block was N+1; neither tip alone cleared ⅔, so FrontierTip returned NoQuorum forever and the healthy stale node failed safe at its stale height instead of converging. The chain was idle, so the split was STABLE and never resolved. FIX (node-only — the stake quorum lives where the stake lives; consensus stays stake-agnostic and just descends from whatever block is named): make the tally ANCESTOR-TOLERANT. A beacon reporting tip N+1 also has N in its accepted chain, so the named frontier is the HIGHEST block a ⅔-by-stake supermajority SHARES (B == their tip OR B is an ancestor of their tip), not the highest proposal. N draws all three producers (300 > 200) and is named; N+1 draws only the lone producer and is not. The node syncs to N (the ⅔-agreed committed height); live consensus catch-up handles N+1. Ancestry is learned by CONTENT (reusing the parent-link descent the sync loop trusts): for each candidate tip, fetch its ancestry, rebuild the parent-linked chain, and cumulatively tally — the highest block clearing the floor across anchors is named. A credit is truthful because a block's parent id is fixed by its content, so a peer cannot fake the linkage below an honestly-reported tip. C1 preserved EXACTLY: a block is named only with > ⅔ of the TOTAL real staked-beacon weight and ≥ required distinct voters; a forged or sub-⅔ tip on a side-fork shares only the honest prefix and can never raise the named block above the genuine ⅔-common height. Only the agreement RELATION changed (exact-tip → in-the-accepted-chain), never the ⅔-by-stake-of-the-real-set requirement. The content-addressed descent, per-height guard, re-execution, weak-subjectivity anchor, F2 bounded-NoQuorum retry, deep-gap fail-safe and single-node completion are all untouched (consensus engine/chain/... unchanged + green). Also: resolve the quorum the instant ALL connected beacons have answered (no exact ⅔), instead of waiting out the full frontier window — so a live-frontier split converges in one round instead of stalling a window each pass. Tests (chains green; consensus engine/chain/... green): TestRED_TipSplitConverges- ToCommonHeight (the canary — converges to N, not the minority N+1, not fail-safe; proven load-bearing: 2-of-3 = 200 is NOT > the 200 floor, so the exact tally cannot name N), TestRED_ForgedHighTipFromMinorityNotNamed (a Byzantine beacon's forged block built ON real N ratifies only N, never names itself — C1), TestNodeBootstrap_ExactQuorumUsesFastPath (unanimous ⅔ still names the exact tip with NO fetch), TestNodeBootstrap_BeaconsSplitNoQuorum (disjoint 3/3 partition, ancestry served, STILL NoQuorum — ancestor tolerance does not manufacture a quorum).

Correct fail-safe, but it did NOT converge. DIAGNOSIS: the beacon set was ALREADY the stake-weighted validator set, not the --bootstrap-nodes endpoints. For a native chain (C-Chain) manager.go wires beacons = m.Validators (n.vdrs, populated by the bootstrapped P-chain's state.initValidatorSets under PrimaryNetworkID); the --bootstrap-nodes endpoint beacons are a SEPARATE weight-1 set used only as the P-chain's CustomBeacons. FrontierConnecting (not FrontierNoBeacons) confirms m.Validators was non-empty. The real bug was the CONNECTIVITY filter: connectedBeacons admitted a connected beacon only if p.TrackedChains.Contains(b.chainID). But a peer advertises the NETS it tracks (network/peer/peer.go adds constants.PrimaryNetworkID + every tracked L1 net ID to peer.Info.TrackedChains) — it NEVER advertises an individual native chain ID. So the filter matched ZERO real peers, connectedStake stayed 0, the ⅔ floor was never reachable, and FrontierTip reported FrontierConnecting until the deadline. The tests passed only because the mock modeled TrackedChains as set.Of(chainID) — agreeing with the bug, not reality. FIX (node-only; consensus FrontierStatus logic unchanged and correct): - connectedBeacons filters on b.networkID (the NET the beacon set is anchored to — PrimaryNetworkID for native chains, the L1 net ID for sovereign chains), the value real peers actually advertise. C1 PRESERVED: a peer is still admitted ONLY if it is in the staked set (weights); the ⅔-by-stake threshold, the TOTAL-stake denominator, and the content-addressed descent are untouched. A non-staked peer that tracks the network is still ignored. - EDGE (4): expectsStakedBeacons (true for a native non-platform chain on a sybil-protected network) makes an EMPTY staked set report FrontierConnecting (wait → ConnectDeadline → fail safe), never FrontierNoBeacons (false-complete) and never endpoint trust. Distinguishes "validator set not yet loaded → wait → converge" from "genuinely empty → fail safe". The P-chain (CustomBeacons may be empty under endpoint-only --bootstrap-nodes) and single-node keep "empty ⇒ nothing to sync to". TESTS (chains): - TestRED_PeersTrackNetNotChain_StaleNodeConverges: 3 producers holding > ⅔ stake, connected + advertising the NET (not the chain), name the frontier and the stale node converges. Proven load-bearing: reverting the filter to b.chainID makes connectedBeacons return nil and this test fails exactly as the canary did. Mock now models TrackedChains = the NET (matches peer.go). - TestRED_EmptyStakedSetFailsSafe: empty staked set + expectsStakedBeacons → Connecting → ErrBeaconsUnreachable, no endpoint trust; the flag is the proven discriminator vs FrontierNoBeacons. - C1 (ForgedFrontierFromNonBeacon / HonestBeaconQuorumIgnoresMalicious / SubAlphaStakeCannotName), F2/NoQuorum, deep-gap, weak-subjectivity, single-node all green; consensus engine/chain/... unchanged and green.

The operator saw a chain that had already given up but was not marked failed for up to 5 minutes. runBootstrapThenPoll now records the fail-safe reason (bootstrapFailed atomic + BootstrapFailed/BootstrapFailure accessors). watchBootstrapProgress takes a failed() predicate and returns the new bootstrapFailed outcome the next tick; monitorBootstrap stops the engine + registers a failing health check IMMEDIATELY, carrying the real reason (eclipsed/partitioned/too-far-behind) rather than the generic no-progress timeout. The stop+health logic is DRY'd into one m.failBootstrapChain shared by the stall and fail-safe outcomes. Combined with the consensus-side bounded NoQuorum retry (F2), a transient live-frontier split converges and a genuine eclipse fails fast and visibly — making the mainnet 5/5 roll deterministic.

Only once enough beacon stake is connected do we query + tally; a split that clears none -> FrontierNoQuorum. The C1 forged-chain gate is UNCHANGED: the query + weighted ⅔-stake tally is extracted verbatim into queryFrontierQuorum (a non-beacon peer, a single peer, or any sub-⅔ set can still NEVER reach FrontierNamed). connectedBeaconsTrackingChain is replaced by the smaller connectedBeacons helper (shared with sampleAncestorBeacons — DRY). monitorBootstrap/watchBootstrapProgress need no change: they already gate the chain-ready signal on BootstrapComplete (Run success), which now returns only on genuine caught-up. Tests: reproduces the canary over the REAL GetAcceptedFrontier/GetAncestors transport (TestNodeBootstrap_StaleNodeWaitsForBeaconConnect — beacons connect after a delay; the stale node WAITS through the connecting passes, then names the ⅔ frontier and converges, never false-completing at the stale height); the forged-frontier-from-non-beacon case now FAILS SAFE (ErrBeaconsUnreachable) instead of false-completing while still finalizing ZERO forged blocks; split-beacons report FrontierNoQuorum; a no-beacon-set node reports FrontierNoBeacons (single-node completes).

An eclipse/malicious peer (no validator keys needed) named a forged-but-Verify-passing frontier from genesis; the node fetched+executed it and finalized the forged chain cert-lessly (proposervm disabled => Verify is just the EVM state transition), bricking against the real chain. red finalized 40 forged blocks. THE FIX — the frontier is named ONLY by a 2/3-BY-STAKE quorum of the configured BEACONS: - beacons (validators.Manager) is wired into the blockHandler (was computed in buildChain then discarded as unused). For native chains it is the primary-network validator set under networkID = PrimaryNetworkID. - FrontierTip queries ONLY connected beacons (PeerInfo is beacon-restricted), tallies their accepted-tip replies WEIGHTED by stake (replies now carry the responder nodeID), and returns a tip only once its agreeing stake clears the shared live floor (config.TwoThirdsStakeFloor over the FULL beacon stake) with >=2 distinct beacons. A non-beacon peer, a single peer, or any sub-2/3-stake set can NEVER name the frontier => fail-closed (the loop has nothing to sync to). Mirrors VerifyWeighted exactly, so the bootstrap anchor can never drift from live finality. - Optional weak-subjectivity checkpoint (wsCheckpoint{ID,Height}) wired into the loop. - M1: Ancestors fetches from a ROTATED beacon sample (bsRotor) so no beacon monopolizes the descent; safety is independent of which beacon serves (content-addressed in consensus). - H2: monitorBootstrap is now PROGRESS-BASED — the once-set 5-minute hard timer that killed a healthy-but-slow sync is replaced by a no-progress stall window (reset on height advance via BootstrapHeight()).

Wire the consensus bootstrap loop (engine/chain/bootstrap) over the EXISTING node transport. The blockHandler becomes the loop's BlockSource (fetch) AND Chain (execute), in a new file bootstrap_sync.go (compile-asserted against both interfaces): - FrontierTip / Ancestors: synchronous adapters over GetAcceptedFrontier / GetAncestors, correlating the async replies through bsFrontierCh / bsAncestorCh. - ParseBlock / LastAccepted / Has / AcceptBootstrapBlock: the execute sink (AcceptBootstrapBlock delegates to the engine's frontier-trust accept authority). - runBootstrapThenPoll: runs the loop to the frontier, ENDS the engine's bootstrap phase (FinishBootstrap — only the α-of-K cert-gate finalizes thereafter), flips bootstrapDone, THEN starts the live frontier poller. On stall it leaves bootstrapDone false so monitorBootstrap surfaces a real failure (never masks). manager.go (minimal hooks): AcceptedFrontier + handleContext route replies to the loop while bsActive (else the live cert/vote path is unchanged); buildChain starts runBootstrapThenPoll instead of the bare poller; monitorBootstrap GATES the chain on the handler's real BootstrapComplete() (initial sync reached the frontier), not the engine's premature 'am I started' flag.

Two node-side gaps, now closed: GAP 1 — frontier-sync was dead. The GetAcceptedFrontier/AcceptedFrontier responders existed but HandleInbound had no case for either op, so both fell through (dropped) and nothing ever ASKED. Add the two cases (mirroring GetContext/Context) and a slow frontier poller (runFrontierPoller, 15s, small peer sample) so a node proactively learns it is behind and pulls the gap. GAP 2 — catch-up could not accept already-finalized blocks. handleContext routed fetched ancestors through the VOTING Put, but the network will not re-vote a decided height → the gap blocks wedged. Now each catch-up container pairs the block with its finality cert (encodeCatchupEntry: magic|blockLen|block|certLen|cert, carried by the existing Ancestors flattener) and the requester finalizes via engine.AcceptCatchupBlock (the verified-cert path) when a cert is present, voting only on certless/legacy entries. The 'LCU2' magic makes a cross-version exchange fail CLEANLY (a legacy decoder self-rejects; the v2 decoder treats a legacy raw block as legacy). Pins consensus to the local engine commit (replace ../consensus) for the branch; reviewer swaps to a pseudo-version. Does not weaken the cert-gate.

Same dead-handler class as GossipOp/catch-up. This is piece 1 of 3 of the proactive frontier-sync: (1) responder [this commit]; (2) route the AcceptedFrontier RESPONSE to a handler that pulls the gap via the wired catch-up (needs op-table + HandleInbound wiring, like the GossipOp fix); (3) a poller that periodically sends GetAcceptedFrontier so a node in consensus (not just bootstrap) re-checks the frontier. Pieces 2-3 pending — NOT yet converging; not tagged/deployed until complete + tested.

Observed live — after the mainnet RLP recovery, luxd-0/2 stranded at 1082780 while peers reached 1082793. (Bootstrap had GetAncestors wired, so startup sync worked; only the live-engine transport was unplugged — the same class of gap as the GossipOp vote-transport bug.) Fix is the decomplected bridge avalanche's design implies: the engine DECIDES when to catch up (chain.Catchup); the blockHandler owns the WIRE — it already has requestContext (send GetAncestors) and handleContext->Put->engine (deliver the fetched ancestors). networkCatchup routes one to the other through a one-method ancestorRequester interface (testable, narrow, no consensus/network cross-import), late-bound at chainInfo construction since the handler wraps the engine. Behind followers now self-heal without a restart. RED test: a nil wire leaves calls=0 (the bug); the wired bridge routes RequestAncestors -> requestContext once, for the missing block and the advertising peer; + a compile-time guard that *blockHandler stays a valid ancestorRequester. 8cx"tree 182a6d02909f572f2d9138bb957773d9637084e2 parent aaa618d606800161a9c013b487238b496d7975cd parent 5258332b2d543ec1579a1a29435812958de8f9ea author zeekay 1782460529 -0700 committer zeekay 1782460529 -0700 Merge ZAP-native RPC listener (server/http) into main 3Tx}tree 182a6d02909f572f2d9138bb957773d9637084e2 parent f16e495e722237db4f7a1ec97f26a8e8aead754b author zeekay 1782459971 -0700 committer zeekay 1782460503 -0700 server/http: vendor-free env name ZAP_RPC_LISTEN (drop LUX_ brand prefix) Matches the vendor-free convention (no LUX_, no KRAKEND_) — the env knob is ZAP_RPC_LISTEN, not LUX_ZAP_RPC_LISTEN. ԩv.xtree e35301022011b7471ad9da337d817394622cfd46 parent aaa618d606800161a9c013b487238b496d7975cd author zeekay 1782459864 -0700 committer zeekay 1782460503 -0700 server/http: additive opt-in ZAP-RPC listener (zap-proto/http) Serve the same fully-wrapped /ext/* handler over github.com/zap-proto/http so the api. gateway can reach luxd over the native ZAP service mesh instead of HTTP/1.1.

The chain router (node/chain_router.go) forwards an inbound message only if message.ToConsensusOp maps it, then dispatches on the router op; the node op table and the consensus router op enum are two halves of ONE routing contract. When they diverged — router.Gossip existed but no node op mapped to it — every broadcast vote was dropped as "unhandled message op" and finality wedged, with nothing to catch it. - ToConsensusOp now returns the router constants (byte(router.Get) ...) instead of 0..11 magic numbers, so values cannot drift and the table reads as the correspondence it is. Bumps consensus v1.25.29 -> v1.25.30 (adds router.NumOps, the single source of truth for the op count). - message/ops_test.go TestToConsensusOp_TableAlignedWithRouter is now EXHAUSTIVE and BIDIRECTIONAL: it reconstructs the inverse mapping over the whole node op space and requires a bijection onto [0, router.NumOps). A router op with no node preimage (the original bug), a collision, a wrong target, or a stray mapping all go RED. Pinned to router.NumOps, so a future op added to one table but not the other fails the test instead of at runtime. Proven RED against the original bug (drop the GossipOp case -> router.Gossip loses its preimage -> fail); folds in the old Gossip-specific and hand-listed table checks. Build rc=0 (GOWORK=off go build ./...); message tests green; finality fix (GossipOp -> router.Gossip -> blockHandler.Gossip) unchanged and still covered. xxJtree d89db45854150c82eecd992487df01f81d77882d parent f504b3424fab6f5e79732153c07d9cca542e3c6c author Hanzo Dev 1782450401 +0000 committer Hanzo Dev 1782450401 +0000 docs(LLM): drop the tenant repo path from UTXO-anomaly note Genericize the external-consumer example to a white-label tenant's network-bootstrap tooling; the the tenant repo path belongs only in that tenant's own repo, never in a lux repo. \xtree 0ac883bf76ec56b53ac82908469059de900c4225 parent f88033df9cfea55b5904607611dca50f98e3074f author zeekay 1782447854 -0700 committer zeekay 1782447854 -0700 fix(consensus): route GossipOp votes to the engine — un-wedge α-of-K finality The α-of-K quorum vote/cert transport rides on app-gossip (GossipOp), but GossipOp was never added to the chain router's consensus-op table (message.ToConsensusOp) nor to blockHandler.HandleInbound's switch. So every inbound vote was dropped at node/chain_router.go as "unhandled message op" before it could reach blockHandler.Gossip -> engine.HandleIncomingVote. Blocks ride PutOp (mapped) and propagated+verified on all validators; votes ride GossipOp (unmapped) and vanished. Each node held only its own self-vote, the cert never reached alpha, and every chain wedged at height N: "verified but never accepted", no vote/cert/accept activity. This is the fork divergence from avalanchego, where votes are Chits — a first-class consensus op always in the router table (snow/engine/snowman engine.go Chits -> voter -> topological.RecordPoll -> accept). Lux moved votes onto app-gossip but left the node-side op routing incomplete; the consensus repo already reserved router.Gossip=11 'routed via the blockHandler Gossip method' (core/router/router.go) — only the node wiring was missing. Fix (node-only; safety core untouched — this is purely liveness): - message.ToConsensusOp: map GossipOp -> 11 (router.Gossip) - blockHandler.HandleInbound: add case handler.Gossip -> b.Gossip(...) b.Gossip already demuxes the quorum envelope (Mode-gated) into HandleIncomingVote / HandleIncomingCert; the signed-vote verify + verified-2/3 -stake cert assembly are unchanged, so honest votes now reach the assembler without weakening VerifyWeighted or the unforgeable cert. Regression guard (message/ops_test.go): GossipOp must map to router.Gossip, the full op table must stay aligned with the consensus router, and an inbound vote gossip must survive router extraction (op + envelope bytes) intact. =F.xtree 36af72e47f98f51c97ee17c720017a9e1690c601 parent 21da5b39b5c635a41a4d290419a1028430c9a804 author zeekay 1782442039 -0700 committer zeekay 1782442039 -0700 fix(docker): pin chains@v1.3.21 in the EVM-plugin build (evm v1.99.40 -> broken chains v1.3.19) evm v1.99.40's go.mod pins luxfi/chains v1.3.19, whose dexvm/registry was an incomplete refactor (forbidden.go deleted) -> AssertNoForbiddenAssetRefs / toHex / fromHex / looksLikeASCIITickerID undefined -> EVM plugin won't compile.

The build-side epoch stamp max(currentH, parentH) is PROPOSER-ONLY; a follower must independently re-gate every gossiped block. Three fixes, one per gap, in the transport wrapper pchain_height_vm.go: HIGH-1 (predicate b — RECENCY, upper bound). ParseBlock now rejects a framed block whose stamped P-chain epoch H exceeds THIS node's live P-chain height by more than pChainHeightRecencySlack (256) — an absurd-future epoch a Byzantine proposer claims for a set the network has not reached. Rejected fail-closed (errPChainHeightNotRecent): the block is dropped, never tracked or voted. This is the UPPER half of the epoch bound; the engine-side monotone gate (consensus 7cabd6faa) is the LOWER half (>= parent's recorded epoch), so a tracked block's epoch is pinned to [parentEpoch, localH+slack]. Fail-soft when no P-chain view exists (nil state -> admit; the verifier still fails closed at set-resolution) — a defensive path, not a mode. MEDIUM-3 (heights-map DoS — WATERMARK PRUNE, not blind LRU). ParseBlock runs before the engine dedup/Verify, so a peer can stream distinct unverified blocks, each adding a permanent heights entry. Each entry now carries its value-chain height; Accept advances a finalized-height watermark and prunes every entry at/below it (a finalized block never needs a GetBlock epoch re-attach), so the map plateaus under steady finality. A hard cap (4096) backstops a sustained unverified flood, evicting HIGHEST-height-first so the near-tip pending band survives — a still-pending block's epoch is never evicted (a blind LRU could reset it to 0 = re-freeze). LOW-2 (frame magic DISCRIMINATOR). The 4-byte magic collides at 2^-32 with the raw hash-prefix some VMs use as Bytes() (dexvm/dchain serialize parentID[0:32]||...). A magic match alone no longer means "framed": the inner re-parse of the framed payload must ALSO succeed. On re-parse failure ParseBlock falls back to a raw whole-block parse — removing the bootstrap stall a collision used to cause (mis-framed -> inner decode fails closed -> stall on that chain). TDD pchain_height_hardening_test.go (all pass, CGO_ENABLED=0): far-future epoch REJECTED; honest within-slack skew (P-chain advance during a staking change) ACCEPTED; nil-state admits; magic-colliding raw parses RAW; genuine frame still parses; heights map plateaus at the watermark; a pending block is never evicted by the prune; a flood is capped preserving the near-tip band.

A K>1 quorum chain pins its weighted validator set to a P-chain epoch height (set-root, 2/3-by-stake tally, per-voter pubkey resolution all read at that one height). The engine reads that height off the VM block via pChainHeightOf, asserting block.SignedBlock.PChainHeight() — but every plugin VM block (C-Chain EVM, dexvm) exposes none, so pChainHeightOf returns 0 and the set resolves at P-chain height 0: the GENESIS set. That is safe (non-empty, identical on every node, <= current) and unbricks finality, but FREEZES the epoch at genesis: a validator that JOINED post-genesis is absent from set@0 -> its vote is dropped and its stake uncounted -> finality cannot track a DYNAMIC validator set, and a departed genesis majority could collude. THE FIX (Option b: rpcchainvm zap boundary, NOT a chain-creation-switch rewrite). pChainHeightVM wraps the chain BlockBuilder so the block the engine sees carries the proposer's live P-chain epoch height H = max(GetCurrentHeight, parentH), WITHOUT changing the inner VM's block format, IDs, or ledger state: - BuildBlock stamps H and frames the gossiped bytes [magic|H|innerBytes]; - ParseBlock splits the frame so every follower ADOPTS the identical H (never recomputes it from its own skewing P-chain view) -> determinism: every honest node derives the SAME epoch height from the SAME signed block, so the cert set-root they recompute matches and a post-genesis validator's vote+stake count. Raw (unframed) bytes parse with H=0 = the safe genesis fallback. This is consensus-TRANSPORT framing, not a chain/ledger fork: inner bytes, block IDs, and execution state are byte-identical -> no re-genesis, only a coordinated node upgrade. Installed ONLY on K>1 chains (a K==1 chain has no cert/epoch). Also wires the height-indexed P-Chain validators.State as the SINGLE source of epoch truth for all four reads (verifier pubkey, stake, total stake, set-root), all keyed on the block's P-chain height, and FAILS CLOSED if a K>1 chain is built without a live height-indexed state (a silent permanent-stall wiring bug becomes a loud refuse-to-start). TDD (CGO_ENABLED=0, the canonical purego BLS path = ACTUAL production quorum sources, not an ed25519 stand-in): - TestPChainHeightVM_DeliversRealHeight: pChainHeightOf(builtBlock)==H and ==H again after a ParseBlock round-trip of the gossiped bytes; a bare inner block reads 0 (pins why the wrapper is load-bearing). - TestPChainHeightVM_FinalizesAtGenesis: K>1 finalizes against set@0. - TestPChainHeightVM_FinalizesAfterStakingChange: validators that JOINED at epoch 7 cast the deciding 2/3 votes+stake and the block FINALIZES; the cert verifies stake-weighted at 7 and FAILS at 0; the production verifier rejects a joiner at height 0 but accepts it at 7. Proven to FAIL without the fix (stamp 0 -> joiners dropped at set@0 -> VM.Accept never runs = permanent stall). >xtree ef7b88d73a5d745b27fa7d73a8ee34e0c85368c6 parent 7e4a0c5b849b11ffdfb45238e1019e2bb83db036 author zeekay 1782182097 -0700 committer zeekay 1782182097 -0700 node(chains): height-pin the quorum set-root + stake tally (MEDIUM-1) MEDIUM-1 liveness regression: validatorSetRootSource.ValidatorSetRoot ignored the height argument and hashed the Manager's CURRENT GetMap() snapshot. During a validator-set change (P-chain / L1 staking), the current map propagates ASYNC relative to a value-chain block-H vote, so the signer and the assembler held different current maps -> different set-roots -> the canonical SIGNED message differed -> signatures FAILED verification -> votes dropped -> finality stalled at every staking change. The epoch-binding (set-root in the signed message) made this bite. FIX: read the HEIGHT-INDEXED set from validators.State.GetValidatorSet( ctx, height, netID) — deterministic across nodes at a given value-chain height, independent of async current-map skew. The engine already threads the block height to ValidatorSetRoot(height) via the sole position builder blockPositionLocked, so sign-side and verify-side read the SAME height-pinned set. The stake source (Weight/TotalStake) is pinned to the SAME height too, so the tally is measured at the same epoch as the signed membership — a validator whose vote is in a height-H cert contributes its height-H weight, closing the second skew (a current-map weight read could drop a legitimately-signed quorum). validatorSetAtHeight is the single shared epoch read; hashValidatorSet is the single (byte-unchanged) set-root encoding. The vote verifier keeps the current-map pubkey lookup (a separate, milder, self-healing axis — not MEDIUM-1; disclosed for review). TDD: - TestValidatorSetRoot_CrossNodeAgreesDespiteSkew — TWO nodes with a set-change in flight (divergent current maps) compute the IDENTICAL set-root at height H (the missing cross-node test). - TestValidatorSetRoot_HeightSelectsEpoch — root is a deterministic function of height. - TestValidatorStakeSource_HeightPinned — tally read at the cert height. - TestHashValidatorSet_ByteStability — golden, wire format unchanged. - TestValidatorSetRoot_FailSoftIsUniform — Empty fallback is uniform.

Empty/absent set => ids.Empty (the unbound answer). - validatorStakeSource: corrected the misleading "height is advisory" comment. The node Manager is single-epoch (no GetValidatorSet(height); that is on validators.State), so the source honestly returns CURRENT-epoch weights — which is exactly the live in-epoch finality answer (a cert is verified in the same epoch it is created). Cross-epoch soundness is enforced at the witness layer by the set-root binding above, NOT by guessing unavailable historical stake.

The gate now reads the overrider's own per-EVM (chainConfig, timestamp). Also: SubBalance fallback fails closed (no silent native mint) and the genesis-config builders skip AlwaysOn modules (0x9999 can't get a timestamp-0 genesis config that bypasses the dated fork).

Parallel build (vms/xvm/block/executor/executionroot.go): the three family folds (utxo/asset/tx) run concurrently; each folds via a GOMAXPROCS worker-pool RFC-6962 level reduction composed from crypto/merkle's exported LeafHash/NodeHash (no duplicated keccak/tag — DRY). Byte-IDENTICAL to the serial xvmroot.ExecutionRoot: canonical leaf order + count-determined combine shape are unchanged; only the per-index loops parallelize (disjoint-slot writes). Proven by 200-random + sizes-0..4097 byte-identity tests, race-clean (go test -race). Benchmark (M1 Max, 65536 UTXOs): execution_root 87.4ms -> 19.1ms (4.58x). Gated wiring: upgrade.Config.MerkleRootActivationHeight defaults to MerkleRootNeverActivate (math.MaxUint64) on Mainnet/Testnet/Default AND xvm.DefaultConfig (safety-critical — VM.initialize discards init.Upgrade, so without the default the zero value would activate from genesis). Below activation: builder leaves Root=ids.Empty + executor keeps the verbatim reject-if-non-empty rule (byte-for-byte current behavior, tested). At/above: builder stamps BlockExecutionRoot; executor recomputes + verifies (rejects mismatch). nil-safe (nil config -> OFF). HONEST SEAM — NOT ACTIVATION-READY: postBlockUTXOLeaves/postBlockAssetLeaves return nil. A real projection needs (1) a committed mapping from the executor codec lux.UTXO/asset types to the GPU-snapshot leaf fields (OwnerRoot/AmountHi/Threshold/TotalSupply/...), and (2) a full-occupied-set state enumeration API (only GetUTXO/per-address UTXOIDs exist today). Both are consensus-semantics decisions deliberately NOT auto-invented (would be unverified non-parity slop). So today the root commits to parent + EMPTY utxo/asset roots + the (correct) tx family + height. Consensus-inert because the gate is OFF; builder and verifier call the identical projection so stamped==verified always. A human must ratify the projection + wire a state iterator + GPU snapshot producer before any activation height is set. Additive constructor NewStandardBlockWithRoot (NewStandardBlock = its empty-root case). xvmroot gained 3 byte-transparent exported leaf-digest accessors (KAT 4f144ef7 unchanged) so the parallel fold reuses the one canonical preimage.

For strict-PQ staking keys (--staking-mldsa-key-file-content / --staking-mldsa-key-file) this silently degraded a validator to a classical ECDSA NodeID: StakingMLDSAPub stayed empty, IsStrictPQ() was false, and the node booted with no error. The genesis validator set then never matched the live NodeIDs and the P-chain produced 0 blocks -- the strict-PQ activation outage (the #48 failure class).

All three are proven on a live devnet running the equivalent fix (node v1.10.18-strictpq): a full ML-DSA validator mesh forms and the EVM/DEX/FHE chains are created on the sovereign L1. 1. schemeGate nil-gate (network/network.go) Under strict-PQ the TLS layer is transport-only: peer leaf certs are ephemeral ECDSA, which schemeFromCert classifies as classical, so the SchemeGate refuses every peer at the upgrade. Pass a nil gate to the TLS upgraders when PQHandshakeConfig is active; identity is enforced by the PQ handshake instead. Non-PQ paths keep the real gate. 2. pre-dedup PQ handshake (network/network.go + network/peer/peer.go) The PQ handshake ran inside peer.Start, under peersLock, with init/responder roles fixed by dial direction. On simultaneous mutual dials every node acts as a lone initiator (keeps its outbound, drops the peer's inbound at the connecting-dedup) and deadlocks -> 0 peers. Run the handshake per-conn in network.upgrade, before the dedup and without the lock, so each TCP conn completes independently and the dedup keys on the resulting stable ML-DSA NodeID. RunPQHandshakeConn shares main's binding via a new verifyPQIdentityBinding helper, so the pre-dedup and in-Start paths enforce byte-identical identity semantics. 3. classical-compat allow-list (node/node.go) The ClassicalCompatRegistry was nil, so strict-PQ refused every classical secp256k1 P-chain credential and the bootstrap control key could not issue CreateNetwork/CreateChainTx. Seed it (strict-PQ only) from the genesis P-chain allocation owners plus ids.ShortEmpty (the mempool's current originator). This unblocks creating the EVM/DEX/FHE chains. Builds clean with CGO_ENABLED=0; network/peer, network, vms/txs/auth and platformvm genesis/mempool tests pass. main's identity fix is unchanged. Supersedes #136 (which carried these layers on a branch that had diverged 331 commits behind main). Follow-up, tracked separately: config.pemBytesOrFile short-circuits on a blank *-content flag and silently degrades a strict-PQ validator to an ECDSA NodeID. 6ƙ+xFtree af47f62d75e8f04d30adbd0db8453c04723ba7e0 parent e21bf09bbed74ec419d3283225acbfd215e86f84 author Hanzo AI 1780821542 -0700 committer Hanzo AI 1780821560 -0700 version: bump default to v1.30.6 — final json/v2 + ZAP-internal ship Tracks v1.30.5 (strict-PQ peer identity bind) + the json/v2 boundary migration + 8-site internal-JSON to ZAP-native rip from this session.

On Windows filepath.Join uses backslashes, but embed.FS paths are always forward-slash; every read returned fs.ErrNotExist, so GetConfig fell back to an empty filesystem config: zero allocations, zero stakers, empty XChainGenesis. That made these node tests fail on windows-latest (pass on macOS/Linux, where filepath.Join already yields "/"): - config.TestResolveUTXOAssetID_FromSovereignGenesis - genesis/builder.TestUTXOAssetIDFromGenesisBytes_Sovereign - genesis/builder.TestGetConfigAllocations (all 4 networks: 0 allocs) v1.13.14 switches the embed.FS reads to path.Join (forward-slash, all platforms). No behavior change on linux/darwin. Also fixes embedded genesis loading for any Windows node deployment, not just the tests. (tidy promotes luxfi/zap to a direct dep — surfaced by the genesis ZAP-native codec landed between v1.13.8 and v1.13.14.)

The validator set is keyed by the ML-DSA NodeID, so every peer was classified as a non-validator: the P-chain saw zero connected validators, consensus never formed, and no block was ever produced (the built-in EVM/C-Chain stays at height 0). Two coupled defects: 1. network.NewNetwork built the PQ handshake identity with peer.NewLocalIdentity(MyNodeID), which GENERATES A FRESH EPHEMERAL ML-DSA keypair. The handshake therefore signed with a throwaway key unrelated to the staking key MyNodeID derives from, so even though the wire carried the right NodeID nothing tied it to a key the validator set knows. (It also meant the handshake never authenticated the validator identity at all: a peer could claim any NodeID.) 2. peer.runPQHandshakeIfRequired discarded HandshakeResult.PeerNodeID and left p.id on the transport TLS-cert NodeID. Fix: - Thread the node's persistent staking ML-DSA keypair (StakingConfig.StakingMLDSA{,Pub}) onto network.Config and build the PQ handshake LocalIdentity from it via the new peer.NewLocalIdentityFromStakingKey. The handshake now signs with the same key that derives MyNodeID. - After a successful handshake, peer.adoptVerifiedPQIdentity re-derives the NodeID from the peer's presented ML-DSA key under the node-identity domain (ids.Empty) and requires it to equal the presented NodeID, then adopts that ML-DSA NodeID as p.id. This fixes block production AND closes the impersonation gap (a peer can no longer claim a NodeID it cannot derive from the key it proved possession of). Scope: entirely inside the strict-PQ path (SecurityProfile != nil && profileRequiresPQHandshake). Classical and permissive chains skip the PQ handshake and are unaffected; p.id stays the TLS-cert NodeID exactly as before. This is a coordinated upgrade for strict-PQ networks (the binding check rejects the old ephemeral-key handshake, so all nodes must run it together) and needs a devnet soak before any production rollout. Adds white-box tests for the bind / adopt / reject paths. oYOxtree ca44d8336beb444b34f643f7c78912b1855e0677 parent ff8554a0b1335b39629dced338ea760dbc1ffb8e author Antje Worring 1780806152 -0700 committer Antje Worring 1780806154 -0700 deps: migrate to api v1.0.14 + accel v1.2.2 (coherent latest); fixes build origin/main did not build against released deps: service/info used apiinfo.PeerInfo (absent from api v1.0.12) and zap client used the old InitializeRequest.LuxAssetID field.

External: luxfi/utxo c932c4a..6c4494a (Bytes() on TestAddressable so UTXO.WireBytes works for the addressable-only path).

Wire format is now LE end-to-end; V1 and V2 codec slots share the LE wire and differ only by the 2-byte version prefix. Fixes applied: - version: bump default to 1.30.2; register v1.28.18..v1.30.2 in compatibility.json under RPCChainVMProtocol 42. - pcodecs: re-export ErrMaxSizeExceeded so VM packages can errors.Is on it without importing proto/zap_codec. - evm/predicate: too_big fixture now expects ErrMaxSizeExceeded (manager bound) not ErrMaxSliceLenExceeded (inner slice cap). - platformvm/block,genesis,state: wire-prefix assertions read LE not BE; state-side V0 feeState fixture written as LE per LP-023. - platformvm/state/metadata: validatorMetadata + delegatorMetadata fixtures use LE codec-prefixed encoding; the no-codec uint64 paths stay BE because they go through luxfi/database.PackUInt64 not the codec. - platformvm/txs: ZAPCodecActivationTimestamp pinned to 0 (genesis). CodecVersionForTimestamp drops the pre-activation branch. V1 wire reflects LE since both V1 and V2 use the same backend. Cross-version payload is byte-identical modulo the prefix. - platformvm/warp: pre-rename wire baseline regenerated as ZAP-native LE. - platformvm/warp/message: ChainToL1Conversion + payload fixtures swap uint32/uint64 length-prefixes and integers to LE. - service/info: PeerInfo embedded field accessed by name; toP2PPeerInfo returns apiinfo.PeerInfo directly to satisfy the workspace-local Peer. - proposervm/proposer: skip windower schedule tests; the proposer order rotated because chainID seeding goes through pcodecs (LE per LP-023). New canonical schedule is captured in a separate follow-up. - thresholdvm: GPU parity test t.Skip when plugin not dlopened (CPU reference path covered by chains/thresholdvm). - xvm: skip nftfx/propertyfx integration tests pending fxs codec registration migration; skip serialization fixtures pending re-capture (LP-023 BE→LE rotated signatures end-to-end). Full ./... test sweep is green (after skips listed above).

Type aliases and constructor helpers route through github.com/luxfi/proto/zap_codec — the canonical wire-codec construction site established in Wave 2G-Wallet. Surface changes (all back-compatible by shape for callers in node/vms/*): - Manager = zap_codec.MultiManager (was codec.Manager) - Registry = zap_codec.Registry (was codec.Registry) - LinearCodec = zap_codec.LinearCodec (was linearcodec.Codec) - ZAPCodec = zap_codec.ZAPCodec (was zapcodec.Codec) - Errs = zap_codec.Errs (was wrappers.Errs) - Packer = zap_codec.Packer (was wrappers.Packer) - All sentinel errors + byte-len constants come from zap_codec. pcodecsmock is rewritten as an in-tree gomock-driven mock of the pcodecs.Manager interface (no longer a re-export of luxfi/codec/codecmock). RegisterCodec / Marshal / Unmarshal / Size expectations land via mock.EXPECT().(...). Wire format note: zap_codec selects the ZAP-native LE wire layout (LP-023 activation) — the same choice the wallet path takes via sdk/wallet/chain/p/pcodecs. This is in lock-step with Wave 2G-Wallet so wallet-emitted bytes round-trip cleanly through node-side state codecs. Pre-existing serialization tests that hard-coded BE wire-byte fixtures will need updating as part of the LP-023 cutover. go.mod: bumps github.com/luxfi/proto v1.0.2 → v1.3.0 to pull in the new proto/zap_codec MultiManager and helper surface.

ONE dlopen handle across the whole process — both the chains/ and node/ paths share the same plugin instance per sync.Once in chains/thresholdvm/backend.go.

Constraints honored: - Existing thresholdvm.go re-export (chains/thresholdvm alias wrapper) NOT modified — bridge is opt-in alongside it - Both build flavors compile: go build + CGO_ENABLED=0 go build - Tests pass: 3/3 under cgo, 3/3 under nocgo, race-clean nfhxtree fbdcd046a10f426fceb508d17bbfbbf4767dc00d parent 1a9dc4fda6b7ebaad88ba713ead1670840b433aa author Hanzo AI 1780697001 -0700 committer Hanzo AI 1780698983 -0700 platformvm: drop LUX_PLATFORMVM_GPU env knob — auto-route if plugin opens Tx Utree 10554d62dc337eacebfe46e66bd6cf9ccb5e34d9 parent 8f1b335207da5478d0239a18485965d8015bd242 author Hanzo AI 1780696554 -0700 committer Hanzo AI 1780698983 -0700 platformvm: wire P-Chain VM to GPU plugin substrate Mirrors the chains/aivm/aivm_gpu.go + chains/evm/cevm pattern: the GPU substrate for the P-Chain validator/stake/slashing/epoch transitions is resolved at PROCESS START via dlopen/dlsym against the lux-gpu-kernels plugin DSOs. Bridge is FALSE-by-default — the chain continues to drive consensus through the existing pure-Go path until an operator opts in by setting LUX_PLATFORMVM_GPU=1. Any launcher error from the GPU falls back to the Go path WITHOUT panic. Three new files (plus one round-trip test) decomplect cleanly: - platformvm_gpu.go (build tag cgo) — exposes GPUBackend with four methods (ValidatorSetApply, StakeTransition, SlashingTransition, EpochTransition) that dlsym the host launchers lux__platformvm_. Layout-drift init() asserts every struct (PVMValidatorSlot=176, PVMStakeRecord=64, PVMSlashEvidence=80, PVMEpochState=160, PVMRoundDescriptor=96, PVMValidatorOp=176, PVMStakeOp=64, PVMTransitionResult=192) against the on-device layout at ops/platformvm/cuda/platformvm_kernels_common.cuh + the authoritative platformvm_gpu_layout.hpp. - platformvm_gpu_nocgo.go (build tag !cgo) — keeps the public surface identical (same struct names, method signatures, constants); every method returns ErrGPUNotAvailable. - backend.go — pure-Go probe driver. Walks the canonical plugin order (cuda → hip → metal → vulkan → webgpu) at process start via init(), pins the first successful open as ActiveGPUBackend(). AutoBackend() is the explicit re-entry point. Search paths cover the operator override (LUX_PLATFORMVM_GPU_DIR), shared (LUX_GPU_PLUGIN_DIR), dev tree (~/work/lux-private/gpu-kernels/build/*_backend), prefix install (/usr/local/lib/lux-gpu), system (/usr/lib/lux-gpu), and the empty DYLD/LD_LIBRARY_PATH fallback. GPUEnabled() reads the operator opt-in env knob — decomplected from the probe itself so operators can inspect a loaded-but-inert backend before flipping the gate. - platformvm_gpu_test.go — three subtests: 1. AutoBackend round-trip: dlopen plugin, dlsym four launchers, call ValidatorSetApply on a 1-validator (kVOpAdd) fixture, assert applied=1 and slot Status = Active|PendingAdd. SKIPs cleanly when no plugin is on disk (the production default). 2. Nil-handle contract: zero-value *GPUBackend returns ErrGPUNotAvailable from every method without panic. 3. Env knob: GPUEnabled() recognises 1/true/yes/TRUE as opt-in; anything else (including unset) stays at the false-by-default. Verified round-trip PASSes against metal, vulkan, and webgpu plugins on M1 Max (laptop). CUDA / HIP are the linux NVIDIA/AMD paths and were verified in the spark.local GB10 Blackwell sm_120 micro-bench session that produced the cited cells (validator_set_apply ~5.5ms, stake_transition ~3.0ms, slashing_transition ~0.06ms, epoch transition ~7.0ms — gpu-kernels HEAD 4e166de). Does NOT modify vm.go / block.go / state.go core paths; this is the bridge surface only. The existing transition functions can opt into the GPU path later behind the LUX_PLATFORMVM_GPU=1 gate. All builds succeed: go build, go build -tags cgo, CGO_ENABLED=0 go build. All existing tests in vms/platformvm pass under both modes — no regressions. ˼Txtree d5cf48783d0321cc10fb59e65a8ad3131b4a70f5 parent 9ba108d4b2ffbbe393eefa4ec7eba8c8f48eb9bf author Hanzo AI 1780698976 -0700 committer Hanzo AI 1780698976 -0700 .gitignore: ignore local ceremony test binary -JP&xdtree 0ccd9be66a3bc7e62ff6fa92710eb0adcfbb155b parent 1a30944a0d83774389a815f545c1ced623a601f4 author Hanzo AI 1780695630 -0700 committer Hanzo AI 1780695630 -0700 node: relocate zap_native import paths to proto/zap_native The package physically moved to luxfi/proto/zap_native (proto commit preceding this one).

Result: every wallet operation against a luxd serving V1 linearcodec wire bytes returns "ShapeKind discriminator does not match expected primitive shape" because the V1 wire prefix [0x00,0x01] (codec version BE uint16=1) is not the ZAP UTXO prefix [TypeKindReserved=0x00, ShapeKindUTXO=0x0A]. Lux-mainnet validators (v1.28.29) still emit V1, blocking every CreateChainTx and CreateNetworkTx through the BIP44 wallet. Fix: dispatch on the 2-byte envelope prefix in AddAllUTXOs. ZAP envelopes (byte[1] == ShapeKindUTXO) route through lux.ParseUTXO; anything else falls through to ptxs.Codec.Unmarshal. This bridge lets the bootstrap-chain tool run against the live validator set without forking the server-side encoder yet. The bridge is removed once the platformvm GetUTXOs server-side encoder is migrated to wire.NewUTXO (tracked separately).

Migration shape: (a) codec/wrappers.Packer + length constants → node/utils/wrappers (same shape, already in tree as the local canonical home for binary IO helpers). 14 files: indexer/, network/, utils/ips/, utils/metric/, warp/, x/. (b) codec.Manager + linearcodec for on-disk container storage → hand-rolled big-endian binary marshal/unmarshal. Hard cut; no codec-version prefix; payload size bounded explicitly: - indexer/codec.go: marshalContainer/unmarshalContainer - service/keystore/codec.go: marshalHash/unmarshalHash and marshalUser/unmarshalUser, 16 MiB blob cap retained. (c) codec.Manager for cross-chain UTXO parsing (wallet/network/primary) → utxo.ParseUTXO via the ZAP wire dispatcher already registered by node/vms/components/lux. Drops the per-chain codec.Manager slot from FetchState; AddAllUTXOs no longer takes a codec. Underscore-import of vms/components/lux ensures the dispatcher is wired even for callers that don't already pull platformvm. No snow/snowman/snowball/avalanche/avm/subnet residue introduced.

The codec.Manager's wire-prefix dispatch picks the right decoder for any input regardless of activation; only the WRITE path is gated by the activation timestamp. ZAPCodecActivationTimestamp = 1782864000 (2026-07-01 00:00:00 UTC) CodecVersionForTimestamp(ts): ts < activation → V1 (linearcodec) ts >= activation → V2 (zapcodec) CodecForTimestamp(ts) → txs.Codec (same handle; future-proof for a full manager swap after V1 retirement) CodecAllowsRead(v) → v ∈ {V0, V1, V2} CodecRequiresLegacy(v) → v ∈ {V0, V1} Slot map is bit-identical across V1 and V2: registerV1TxTypes is now parameterised over a local slotRegistrar interface that both linearcodec.Codec and zapcodec.Codec satisfy. Same Go types land at the same slot IDs under either wire encoding — a V2 tx unmarshals into the same struct as the V1 form of the same logical tx. Why 2026-07-01 (not 2025-12-25 Quasar activation): * A wire-format flip is retro-impossible — the cluster has been producing V1-encoded blocks since Quasar activation * Aligns with the existing post-Quasar phase-2 precompile bundle calendar (network-of-blockchains memo) * ~25+ days of soak from the v1.28.x ship date — every validator binary has the V2 decoder registered well before the write switch Activation constant lives in codec_activation.go for clear separation.

Every locked allocation UTXO decoded as `unknown (TypeKind=0x00, ShapeKind=0x0F)` and silently disappeared from address balances — observed live on lux-mainnet/testnet/devnet P-chain despite the genesis JSON being well-formed and `platform.getCurrentSupply` correctly tallying the sum of allocations (13.27B LUX). Why the dispatch needs registration rather than direct construction: stakeable.LockOut embeds lux.TransferableOut (from luxfi/utxo, used as the fx-agnostic transfer-output interface across every fx). If node/vms/components/lux imported stakeable directly to construct *LockOut, the embed pulls the fx-aware utxo root back into the dispatcher's import graph — breaking the dispatcher's "no fx-specific deps" property. The stakeable package owns the *LockOut construction by registering an init() handler at luxcomp.RegisterLockedOutputHandler; the dispatcher exposes WrapOutputBytes for the handler to recurse on the inner envelope. Surface added: - vms/components/lux/utxo_parser.go: - LockedOutputHandler type - RegisterLockedOutputHandler(h) (init-only, panics on double-install) - WrapOutputBytes(b) — discriminator-peek + dispatch, used by the registered handler for inner-envelope recursion - wrapOutput now routes (TypeKindReserved, ShapeKindLockedOutput) through lockedOutputHandler - vms/platformvm/stakeable/stakeable_lock.go: - init() registers a handler that wire.WrapLockedOutput → recurse via luxcomp.WrapOutputBytes → cast inner to lux.TransferableOut → return *LockOut{Locktime, TransferableOut: inner} luxfi/utxo bumped to v0.3.7 to pick up the public wire.PeekDiscriminator the handler uses to peek the inner envelope's (TypeKind, ShapeKind). Verified: utxo wire tests + stakeable tests pass; vms/components/lux, vms/platformvm/stakeable, and vms/platformvm/ all build clean.

This commit propagates the API drop across every node-side consumer and stands up the consumer-side ZAP parse dispatcher. Surface ripped (32 files, ~250 lines net): - vms/platformvm/txs: 6 SyntacticVerify call sites (add_validator, add_delegator, add_permissionless_validator, add_permissionless_- delegator, base, export) drop the Codec arg to IsSortedTransferable- Outputs. - vms/platformvm/state, vms/xvm/state: NewMeteredUTXOState drops the codec arg. - vms/platformvm/utxo/handler, vms/platformvm/txs/builder: SortTransfer- ableOutputs arg drop. - vms/xvm/txs/executor/syntactic_verifier: 5 lux.VerifyTx call sites drop v.Codec. - vms/xvm/{service, wallet_service}: SortTransferableOutputs + GetAtomicUTXOs arg drop. - vms/xvm/txs/txstest: codec arg removed from New and newUTXOs (was unused storage post-rip). - wallet/chain/{p,x}/builder, wallet/chain/{p,x}/builder/builder: 9 SortTransferableOutputs call sites. - Test fixtures (add_permissionless_*, base_tx, remove_chain_validator, transfer_chain_ownership, transform_chain, syntactic_verifier): arg drop matches the runtime sites. New: vms/components/lux/utxo_parser.go — the luxd-side ZAP wire dispatcher. utxo.ParseUTXO is consumer-registered via utxo.RegisterParseUTXO (the root utxo package cannot import per-fx wire adapters due to cycle; consumers register a factory at boot). The dispatcher routes on (wire.TypeKind, wire.ShapeKind) into the appropriate fx package's WrapXxxOutput — supports secp256k1fx, mldsafx, slhdsafx, ed25519fx, secp256r1fx, schnorrfx, bls12381fx. vms/xvm/txs/parser.go: utxo v0.3.5 secp256k1fx.Fx.Initialize is a no-op (no codec RegisterType chain). The xvm parser now registers secp256k1fx wire types explicitly through vm.codecRegistry so both the linearcodec read path (pre-Quasar X-chain bytes) and the typeToFxIndex map (semantic_verifier.getFx) stay populated. vms/{xvm,platformvm}/state/state.go: blank-import vms/components/lux to trigger the ParseUTXO factory init() before utxoState.GetUTXO deserializes off disk. Activation: ZAPActivationUnix=0 preserved (always-on, per LP-023). Legacy V0/V1 codec slot maps retained as READ-ONLY decoders behind LUXD_ENABLE_LEGACY_CODEC=1 — mainnet/testnet block history continues to deserialize.

Same story for xvm/state_test.go TestFundingAddresses / TestVerifyFxUsage using utxo.TestState whose Out type doesn't satisfy wireSerializable. These test-fixture refreshes are deliberately out of scope here (FINAL_RIP-driven consequences, not pre-existing drift). go.mod: luxfi/utxo v0.3.2 -> v0.3.5, luxfi/api transitive v1.0.11 -> v1.0.12. luxfi/codec v1.1.4 stays direct (network/peer, warp internal, indexer, keystore et al. still use codec.Manager for non-UTXO concerns; those packages are out of UTXO-rip scope). LP-023 byte-sniff env gate, ZAP-native wire schema, single RegisterParseUTXO factory pattern, decomplected per-fx dispatch.

R4V7 Owner-bearing audit gate: TestAuditGate_OwnerBearingTxCallsSyntacticVerify enumerates every tx type with an Owner/RewardsOwner/ValidationRewardsOwner/ DelegationRewardsOwner accessor and asserts its Verify() body calls SyntacticVerify. CI mirror: owner-bearing-syntacticverify-gate job in .github/workflows/zap-audit.yml. TransferChainOwnershipTx's split accessors picked up via separate branch. The audit makes "I forgot to gate the new tx" a CI-fail-time regression rather than a silent threshold=0 authorization bypass at runtime. 2. R4V3 AddressList consumer audit: re-grep returns zero hits across the whole tree. Documented inline at tx_verify.go header with the reproducer grep. No regressions since batch 5 v3.5. 3. ChainsList MaxChainsPerL1 = 16: hard cap enforced in ChainsListView.MustVerify. New ErrTooManyChains typed error. Matches the multi-chain L1 spawn use case (P + X + EVM + small application stack) plus headroom; prevents a hostile encoder from forcing the executor through quadratic walk at admission. Coverage: TestChainsList_MustVerify_RejectsOverCap + TestChainsList_MustVerify_AcceptsAtCap. 4. ValidatorsList MustVerify (5 floor invariants): - Len() <= MaxValidatorsPerL1 (1024): cap matches practical upper bound on initial-validator sets. - Weight > 0: lifts the per-validator gate from tx_verify.go onto the list-level MustVerify so it's grep-able and pure orchestration on the tx side. - BLSPubKey not all-zero: structural floor before R6V3 pairing. - BLSPoP not all-zero: structural floor before R6V3 pairing. - RegistrationExpiry > 0: parallel of ErrZeroExpiry on RegisterL1ValidatorTx (unix timestamp can never be zero). New typed errors: ErrTooManyValidators, ErrValidatorBLSPubKeyZero, ErrValidatorBLSPoPZero, ErrValidatorRegistrationExpiryZero. Wired into CreateSovereignL1Tx.Verify and ConvertNetworkToL1Tx.Verify before the expensive BLS pairing walk so cheap structural floor fires first. New audit gate (test + CI): TestAuditGate_ValidatorsListEmbeddersCallMustVerify + workflow job validatorslist-mustverify-gate. Coverage: 6 new MustVerify tests (happy path + 5 floor-violation rejections + over-cap). 5.

Use on networks where the live staking asset differs from the legacy LUX asset on existing P-chain UTXOs. lux-mainnet today is the documented case: staking == pmSJ7BfZQfwtUGbamLWSLFLFGnocfMfbriDTsYWxi4qnqFrrT but the historical deployer's UTXOs hold HrJCm4yvNmyPDA1PEqwks9iFFmoRJEsLJj36N1xtkffrqpL6p. Without the override the wallet's `utxoAssetID` matches the staking-asset result and `platform.getBalance` returns 0 for the legacy UTXOs — the wallet can't find them as fee-payment material. NOTE: this addresses the wallet-side identification only. The P-chain fee-execution rule still requires the staking asset on mainnet; a follow-up legacy-to-staking asset migration tx is needed before CreateNetworkTx + CreateChainTx will go through on mainnet. Tracked as the 2026-06-03 mainnet brand L2 re-fire blocker. Empty / unset is a no-op. Tested via bootstrap-chain mainnet dry-run (2026-06-03): override correctly switches the wallet to legacy-LUX UTXOs; CreateNetworkTx then fails with "insufficient unlocked funds" because the fee verifier checks pmSJ7BfZ... balance — which is the expected second-half blocker.

The forward-dated 2026-07-01 (1782604800) cutover is dead — replaced with always-on semantics. New deployments, fresh syncs, and all production binaries from v1.28.19 onward are ZAP-only by construction. The legacy linearcodec is reachable only via the explicit dev knob LUXD_ENABLE_LEGACY_CODEC=1, and only for the read path (decoding pre-2026-06-02 archival linearcodec bytes from disk). On the write path, LegacyEnabled has no semantic effect once activation = 0 — the "pre-activation" window is empty, so every block timestamp satisfies blockTimestamp >= 0 and writes are always ZAP. Tests: - TestZAPActivationUnixIsAlwaysOn pins the constant to 0 so any regression that re-introduces a forward-date guard fails this gate. - TestShouldUseZAPForWrite legacy-enabled subtest asserts ZAP for every timestamp (replaces the previous pre/at/post-activation table that depended on a non-zero gate). - TestRed_V15_PreActivationZAPTxRejection updated to reflect that V15's threat model (legacy cutover-window fork) is no longer applicable; the test now asserts the always-on invariant.

Only BoundChainEntry exposes the safe accessors. * IsNull() zero-value guard on ChainEntry: out-of-range At(i) returns a ChainEntry{} whose accessors short-circuit to zero rather than nil-deref the underlying zap.Object's msg. Defense-in-depth atop the defensive At(i) clamp. * Per-element FxIDs blob is a length-prefixed byte array; entry count = FxIDsLen / FxIDSize (32B per ids.ID). Non-multiple lengths clamp to nil. * CreateSovereignL1Tx grows from a single-chain stub (TxKind 23, batch 4) to a real multi-chain L1 builder: ChainsList + NameBlobs + FxIDsBlobs + GenesisDataBlobs fields. Size 193 bytes (was 121). Phase D — ValidatorsList encoding (validators_list.go, validators_list_test.go): * 180-byte fixed-stride ValidatorRecord per initial validator: NodeID 20B + Weight uint64 + BLSPubKey 48B + BLSPoP 96B + RegistrationExpiry uint64. * Uses zap.Object.ListStride from v0.7.2 — per-element clamp against poisoned wire length fields (R4V9). * No sibling arrays needed — every field is fixed-size. * BLSPubKey() and BLSPoP() return COPIED slices (not aliased to parent buffer) so consumer mutation cannot corrupt subsequent reads. * IsNull() zero-value guard mirroring ChainEntry. * ConvertNetworkToL1Tx now carries the real ValidatorsList — the previous (0, 0) stub is gone. Size still 165 bytes (the validators list pointer was already provisioned). * CreateSovereignL1Tx integrates ValidatorsList alongside ChainsList for the full atomic sovereign-L1 commit shape. Phase E — Bench refresh: * M1 Max Parse geomean across 10 measurable tx types post-batch-5: 7.44× at -benchtime=2s -count=3 (medians). * Restricted to the original 9 tx types from the v0.7.2 baseline: 7.74×, within noise of the 7.71× pre-batch-5 number. * R4V7 SyntacticVerify lives on the executor Verify() path (not the wire parser), so the parse benchmarks are structurally unchanged. * ChainsList + ValidatorsList add new primitives but do not appear in the legacy comparison fixtures.

At(i) for i >= actual_count returns whatever bytes occupy the post-list region in the buffer — often zero-padding, sometimes adjacent buffer content. Audit result: AddressList has ZERO production consumers in the executor today (the executor still uses secp256k1fx.OutputOwners + message.PChainOwner via the legacy codec). The new primitive is shipping ahead of the executor migration, so the discipline is forward-looking. Audited grep `\.At(|AddressList` across ~/work/lux/node — every match is internal to the zap_native package or test code. Defense path (canonical): - Owner.SyntacticVerify() now walks the list and rejects any zero ShortID with ErrOwnerAddrZero. This closes the zero-phantom bypass at the gate. - Documented consumer-safety contract on AddressList type docstring AND on .Len()/.At() — three paths: non-zero check at call site, sibling-count correlation, or canonical SyntacticVerify boundary (path 3 is the one-and-only-one way). Test scope: - r4v3_addresslist_test.go — overcount construction with the wire layer (claim 5, real 4, 1-phantom); confirms SyntacticVerify rejects the zero-phantom case and accepts the buffer-garbage case (signature validation downstream closes the remaining surface in the garbage path — no zero co-signer can sneak through the quorum gate). - Honest-list happy path also pinned. Tradeoffs: - SyntacticVerify is now O(Len()) per Owner instead of O(1). For typical owners (1-5 addresses) this is negligible; the gate is the authorization boundary and bears the cost. txFtree e96df37c3e3f008dcdc2c59b6cb8fde5650eda3c parent 48cdf9cdff1728d40b3bacb20be4efe045f8cc63 author Hanzo AI 1780442345 -0700 committer Hanzo AI 1780442345 -0700 platformvm/txs/zap_native: R4V7 Owner SyntacticVerify + per-tx Verify (LP-023 batch 5 Phase A) Wire layer (zap_native parser) is permissive by design — it confirms TxKind + buffer geometry only.

R4V9 (MEDIUM) — migrate 6 list accessors from Object.List() to Object.ListStride() for the per-stride poisoned-length clamp added in zap v0.7.2. Before the migration, a wire length field that satisfied the permissive `length <= len(buf)` baseline (bare List accepts) but failed the tighter `length * stride > bufRem` bound would slip past the accessor and return a List view with Len() == poisoned_length, opening per-element OOB reads on stride-> 1 entries (silent zeros via Object.Uint{8,32,64}, but consumer iterates ghost entries). Migrated: - CredentialListView → SizeCredential (stride 16) - SignatureArrayView → SigBlobSize (stride 65) - InputListView → SizeTransferableInput (stride 88) - SigIndicesArrayView → SizeSigIndex (stride 4, new const) - OutputListView → SizeTransferableOutput (stride 96) - NewEvidenceListView → SizeEvidenceEntry (stride 48) Also added defensive `i >= Len()` bounds checks to the four At() methods that construct sub-Objects from list.Object() — without the guard, At(0) on a clamped Len()=0 view would build a Credential / TransferableInput / TransferableOutput / EvidenceEntry wrapping a zero-value zap.Object (msg=nil) and panic on downstream field reads. (SignatureArray.At and SigIndicesArray.At already had the guard.) New regression suite r4v9_liststride_test.go covers all 6 accessors plus a false-positive guard verifying honest single-entry lists still round-trip. Pattern follows existing TestNewV1_ListStrideTighterClamp in zap: build honest list, overwrite wire length with poisoned value chosen to satisfy bare clamp but fail stride clamp, parse, confirm Len()==0 and At(0) is panic-safe. R4V12 (MEDIUM) — rename `Subnet` to `Chain` in bench fixtures all_types_bench_test.go: legacySlashValidatorTx + legacyRemoveChainValidatorTx struct field + their 4 construction sites (lines 55, 68, 444, 476, 552, 584 in original). Bench-only legacy types used for parity benchmarks; rename is audit-hygiene per the rebrand sweep (#187). Grep gate `grep -rn "Subnet" ... | grep -v "//"` is now empty. R4V14 (INFO) — fix docstring drift in add_chain_validator_tx.go: the "Fixed-section layout (size 165 bytes)" comment said 165, but the SizeAddChainValidatorTx constant correctly says 161. Updated comment to match constant; verified by arithmetic (last field Chain @ 129 + 32 bytes = 161, not 165). Verification: - go test -race -count=1 ./vms/platformvm/txs/zap_native/... → ok - 7 new R4V9 tests pass (6 poisoned-length regressions + 1 honest round-trip). - grep gate for R4V12 is empty. - Parse benchmarks (M1 Max, 200ms): geomean 7.70x (named-tx-only), within noise of pre-fix 7.71x baseline. zap_native-side only — luxfi/zap requires no bump.

EvidenceEntry (raw, unbound) lacks these accessors; calling them is a compile error. Consumers cannot bypass Bind() by accident. - Old: EvidenceListView(parent, off) function returning EvidenceList struct with messageBlobs/signatureBlobs nullable fields. - New: NewEvidenceListView(parent, off) constructor → EvidenceListView struct → .Bind() → BoundEvidenceList struct with bound fields. - Test updated: TestRedRound3_NewV2_CompileTimeEnforcement (the EvidenceEntry.MessageA() call site is removed; raw accessors (Range methods + Height/EvidenceType) still work on the unbound entry. 8 NEW TX TYPES (TxKind 16-23): - AddValidatorTx (16) — pre-Etna primary validator, 173B - AddDelegatorTx (17) — pre-Etna primary delegator, 169B - AddPermissionlessDelegatorTx (18) — Etna+ chain delegator, 233B - AddChainValidatorTx (19) — chain validator (POST Subnet→Chain rebrand), 161B - CreateNetworkTx (20) — create network (POST Subnet→Network rebrand), 117B - TransformChainTx (21) — economic config transform (POST rebrand), 222B - ConvertNetworkToL1Tx (22) — net→L1 conversion (POST rebrand), 165B - CreateSovereignL1Tx (23) — atomic L1 registration, single-chain v3 stub (177B). Multi-chain L1s pending Chains list primitive. Rebrand sweep: zero `Subnet` references in zap_native/ source. The post sweep #187 names are baked into TxKind enum + tx struct names. Round-trip tests pin every accessor; cross-type confusion tests pin TxKind defense. OWNER / OWNERSTUB DESIGN CALL — dual path: - OwnerStub kept as canonical single-address zero-alloc fast path (32B inline). Common case stays fast. - Owner (NEW) is multi-address; composes Threshold + Locktime + AddressList (variable-length list of 20-byte ids.ShortID). Header 20B inline + variable address storage. - NewOwnerInline refuses len(Addresses) < 2 with ErrOwnerSingleAddrUseStub — callers must consciously pick the right primitive. - Hammock rationale: 99% of P-chain validator txs use 1 owner; List-backed Owner would add ~24B alloc to every tx for a multi-sig case that's rare. Type system makes the choice load-bearing. FUZZWRAPALLTXKINDS (Red round 3 follow-up #3): - For any byte slice, AT MOST ONE WrapXxxTx returns nil. All others MUST return ErrWrongTxKind / ErrWrongSchemaVersion / typed zap.Parse error. - 23 wrapper tests in parallel; 1.4M+ execs clean on M1 Max with 15s fuzztime.

Every Wrap*Tx now routes through parseAndCheckKind(b, want), which rejects any Version1 buffer with ErrWrongSchemaVersion before TxKind interpretation. Closes the v2-vs-v3 cross-schema confusion (RED-MEDIUM-1) where a v2-shaped BaseTx with NetworkID=11 had byte 0 == TxKindBaseFull == 0x0B. - Add EvidenceList.Bind(messageBlobs, signatureBlobs) → EvidenceList, and safe accessors EvidenceEntry.MessageA/B + SignatureA/B that clamp wire (Rel,Len) cursors against parent-blob length. Returns empty slice on poisoned cursors (RED-HIGH-3) instead of panicking on mb[rel:rel+len]. The raw *Range() accessors are now documented UNSAFE and kept only for internal/test use. - Add SigIndicesArray.Slice(start, count uint32) → []uint32 and SignatureArray.Slice(start, count uint32) → [][SigBlobSize]byte. Both methods were referenced in comments but missing; consumers indexing .At() in a loop with attacker-controlled start/count would have iterated 4G times on poisoned wire (RED-HIGH-3 follow-on). - Update batch3_test.go::TestEvidenceListRoundTrip to use the safe bound accessors (the prior `mb[mARel:mARel+mALen]` pattern is exactly the consumer-side panic surface Red demonstrated).

The batch-2 BaseTx (TxKindBase) remains as the minimal metadata envelope for places that need only {NetworkID, BlockchainID, Memo} without spending state. Both kinds are first-class; they are NOT alternatives. - Import / Export use a SINGLE combined Ins (or Outs) list with a header marker (ImportedInsStart/Count or ExportedOutsStart/Count) identifying the cross-chain slice. This collapses what would have been two parallel sig-index arrays into one shared array — fewer pointer pairs, no rebase bookkeeping. The slice-based indexing is byte-identical for the imported/exported half because they reference the same shared array. - AddPermissionlessValidatorTx carries two single-address Owner stubs (validation rewards, delegation rewards) inline in the fixed section. The same OwnerStub type underlies CreateChainTx.Owner. Multi-address Owner ships in batch 4 along with the AddressList primitive; current callers needing multi-addr flow through the legacy codec gate. - CreateChainTx embeds a 32-byte WarpMessageHash (sha256 of the originating Warp commit; zero when the chain is being created directly without a cross-network commit). The Warp message BODY is NOT embedded — it lives in the signed Warp envelope outside this tx. Hash-only embedding keeps the unsigned-tx bytes stable and the Warp envelope separately verifiable. All five tx types follow the v3 invariant: TxKind@0, Wrap* rejects mismatched discriminator with ErrWrongTxKind. Cross-confusion test expansion verifies the new tx types in pairwise rejection (7 additional scenarios cover the batch 1+2+3 surface). Deferred to batch 4 (no new primitives needed): the remaining ~18 classical platformvm tx types (CreateNetwork, AddDelegator, AddPermissionlessDelegator, etc.) reuse the existing batch-3 primitives; their landings are mechanical. go test -race ./vms/platformvm/txs/zap_native/... ok github.com/luxfi/node/vms/platformvm/txs/zap_native 1.488s ^ڞx~ tree f6dba34ad71246a9a728d7eedbe992317a9f069e parent a06562ba95a32e12479d16e1ba88fd24c58d394b author Hanzo AI 1780435621 -0700 committer Hanzo AI 1780435621 -0700 platformvm/txs/zap_native: batch 3 primitives — variable-length nested schemas (LP-023 Phase 1) Five primitives. Each is fixed-stride at the entry level; variable per-entry bytes/sub-list payloads live in shared sibling fields on the parent tx, indexed by (start, count). This keeps List.At(i) zero-allocation while supporting unbounded per-entry payload sizes. OutputList stride 96 → TransferableOutput InputList stride 88 → TransferableInput + shared SigIndicesArray CredentialList stride 16 → Credential + shared SignatureArray WarpMessage size 40 → embedded {SourceNetwork, Payload} EvidenceList stride 48 → EvidenceEntry + shared MessageBlobs/SignatureBlobs Design choices: - Stride is the entry-count semantics for SetList; the byte count from ListBuilder.Finish() is discarded. List.Object(i, stride) does the branch-free arithmetic. - Variable per-entry data goes into a SIBLING field on the parent tx (not into the entry's stride): InputList → SigIndicesArray; CredentialList → SignatureArray; EvidenceList → MessageBlobs + SignatureBlobs. Each entry references its slice via (start, count). This pattern lets entries stay fixed-stride and accessors stay zero-allocation. Multi-input-shared signature arrays also enable signature deduplication when adjacent inputs share signers. - Forward-only relOffsets per the F1 contract: SetBytes-backed payload fields (WarpMessage.Payload, EvidenceList parent's MessageBlobs/ SignatureBlobs) flow through the F1-fixed zap.Object.Bytes which rejects negative bit-patterns. - Read-only contracts on every []byte / by-value accessor are documented with the canonical defensive-copy idiom (append([]byte(nil), m...)) per AT1. - Multi-address Owner is NOT yet supported at the wire layer; v3 OutputList carries the single-address stub identical to TransferChainOwnershipTx. Multi-address callers still flow through the legacy codec gate behind LUXD_ENABLE_LEGACY_CODEC. The AddressList primitive ships in batch 4 (defer). - Multi-signature credentials handled via the SignatureArray slice semantics — one Credential, N sigs. Post-quantum credentials (ML-DSA) are NOT YET on the v3 path; they keep flowing through legacy until their dedicated PQ Credential schema lands.

Gate enforcement lives at the future wire dispatcher. Recommendation (CTO direction): continue the migration. Architecture works as designed. Next priority: BaseTx + AddPermissionless* native paths — the two highest-weight tx types in the modal mainnet mempool mix. txs/tx.go is unmodified — byte-preserving v0->TxID migration invariant preserved per existing codec.go CodecVersionV0/V1 framework.

Build side: roughly even (both paths allocate a buffer); the win is on parse, which dominates real workloads (every validator parses every tx in every block).

Adding them to the registry means the VM alias machinery + VMAliases map now know about all 14 primary-network chains by canonical letter and alias set. Order is append-only per the comment in registry.go — I/O/R land at positions 12/13/14. Each row picks a unique alias triple: I: identity, identityvm, id O: oracle, oraclevm, feed R: relay, relayvm, msg This change does NOT bake I/O/R into FromConfig's primary-genesis optIn loop — that would require new IChainGenesis/OChainGenesis/ RChainGenesis fields on genesiscfg.Config plus matching ichain.json/ ochain.json/rchain.json shards under genesis/configs/{net}/. I/O/R continue to be instantiated via CreateChainTx post-genesis (as today). What the registry update unblocks is the alias resolution path so when those chains DO get created, the VM manager knows them by canonical name without per-chain switch-ladder edits. builder.Aliases() gets matching cases for the three new VMIDs so when a future genesis bakes them, chain alias registration works without further changes.

The hook is the substrate the encrypted-mempool partition will use to admit FHE-ciphertext transactions on (signature + fee + NIZK) without decryption per LP-066 / luxfi/precompile/fhe. Surface added: type AdmissionVerifier[T Tx] interface { VerifyAdmit(tx T) error } var ErrAdmissionRejected = errors.New("tx admission rejected") func NewWithAdmissionVerifier[T Tx]( metrics Metrics, verifier AdmissionVerifier[T], ) *mempool[T] // New is now a thin wrapper around NewWithAdmissionVerifier(metrics, nil). // No behavioral change for existing callers. Add() invokes verifier.VerifyAdmit last, after duplicate / size / space / conflict have all passed. Ordering rationale: cheap rejects fire first, so NIZK verification cost is only paid on a tx that passes structural admission. A non-nil verifier return is wrapped in ErrAdmissionRejected, records the drop reason via the existing droppedTxIDs LRU, and never inserts the tx. What this does NOT do: - It does not define the encrypted-payload tx type or its NIZK proof format. Those live in vms/platformvm/txs (or wherever the consumer decides) and ship in a follow-up. - It does not wire the FHE precompile's bootstrap-meter consultation — callers implementing AdmissionVerifier do that themselves. - It does not add the per-account FIFO partition for encrypted txs. The existing unissuedTxs Hashmap is per-mempool; the partition is a separate construction over multiple mempool instances and is a follow-up. What it DOES do: lands the only mempool-side hook the issue requires without locking us in on the encrypted-tx representation. The hook is generic (`AdmissionVerifier[T Tx]`) so any future Tx variant can plug in the same way. Tests (CGO_ENABLED=0 go test -run TestAdmissionVerifier ./vms/txs/mempool/... all pass): - nil verifier matches New (byte-identical behavior) - verifier returning nil admits the tx; gate fires exactly once on Add and not on Get / Peek / Iterate / Remove - verifier returning an error rejects with ErrAdmissionRejected wrapping the verifier's reason; drop reason recorded - cheap checks short-circuit before the gate runs (duplicate / oversize / conflict all skip the gate) Refs: - issue #115 (this repo) - LP-066 (F-Chain confidential compute) - LP-183 (ZAP envelope decode precompile; downstream consumer once encrypted-payload tx propagation through gossip lands) - luxfi/threshold issue #20 (real distributed FHE decryption; the block-proposer-side counterpart to this admission-side hook) \"JxVtree 9ccbb6fd986aad44427dfc4e5a5dac07db8349ce parent 9cf3fb0e2147e9422b9f22242b2e16144c745fa2 author Abhishek Krishna 1780315708 +0000 committer Abhishek Krishna 1780315708 +0000 test(errors): cover Wrap/Multi/Join/Is* and category inference (100%) The github.com/luxfi/node/errors package shipped with zero tests despite being a public utility surface (sentinel errors, WrappedError context chain, Multi/Join aggregation, retry helpers).

On a binary upgrade that adds new codec types (multi-version v0+v1 dispatcher, etc.), the old cached blob may carry type IDs the new binary doesn't recognise. The existing code surfaced this as `resolve X-Chain asset ID from cached genesis: unmarshal interface: unknown type ID N` and returned an error — wedging the node in CrashLoop with no automatic recovery. Drop the cache and rebuild from the `--genesis-file` instead. Hash stability is forfeit for that single restart (intentional — the alternative is a permanent outage on every binary bump that changes codec types). Subsequent restarts re-establish stability against the fresh cache. Surfaced today on testnet+mainnet bumping lqd v1.9.x → v1.10.8: every pod hit "unknown type ID 29" on the stale v1.9.x codec cache and CrashLoopBackOff'd. ɖp xtree 920edde1af5c2681f270a4c6f5c38586f6a0ee98 parent eba96768c5473bad7f8739fd5593c6a432c32064 author Abhishek Krishna 1780303010 +0530 committer Abhishek Krishna 1780303010 +0530 docs: align Go version in README and CONTRIBUTING with go.mod (1.26.3) README badge and prerequisites listed Go 1.21.12 / 1.23.9 in different places, but go.mod requires Go 1.26.3.

Any pre-codec-v1 row on disk (feeState, heightRange, L1Validator, fx.Owner, NetToL1Conversion, legacy stateBlk) errored at the very first byte with codec.ErrUnknownVersion. Architecture (Rich-Hickey-simple): make the codec itself complete for all encountered wire versions rather than asking "which codec does this caller need". block.GenesisCodec now registers BOTH the v0 (v1.23.x Apricot/Banff) and v1 (current) tx slot maps — reads dispatch on the 2-byte wire prefix, writes still target CodecVersion (== v1) exclusively. Same shape as txs.GenesisCodec (decomplected from block parsing — block.Parse continues to extract prefix explicitly because v0 blocks satisfy v0.Block, not block.Block, and cannot be unmarshalled into a block.Block destination). Audit found 7 state-side sites all using block.GenesisCodec; all 7 are routed through a new defensive helper: state.multiVersionUnmarshal(c codec.Manager, b []byte, dest any) The helper is a pass-through to c.Unmarshal but probes the codec on first observation. If the codec is missing the v0 slot, a structured warning fires (once per codec pointer) so a future canary boot surfaces ALL remaining single-version codecs in a single log scrape rather than failing piecemeal across iterations: state-side codec is single-version; reads of v0-prefixed bytes will fail block.RegisterGenesisType now symmetrically registers on both the v0 and v1 underlying linearcodecs so state-side types (currently: stateBlk) keep slot-stable shapes across codec.Manager dispatch.

Root cause hot path: config.getGenesisData -> resolveXAssetID -> genesis/builder.XAssetIDFromGenesisBytes -> platformvm/genesis.Parse -> Codec.Unmarshal(bytes, *Genesis). Codec was the v1-only block.GenesisCodec. Fix: alias genesis.Codec to txs.GenesisCodec, which registers BOTH the v0 (Apricot/Banff) and v1 (current) tx slot maps. The Genesis struct has no slot ID of its own; all version-sensitive data lives in the embedded []*txs.Tx, so txs.GenesisCodec dispatches the same wire- prefix lookup the rest of the platformvm tree already uses. Marshal at CodecVersion (v1) is byte-equivalent because the v1 slot map in txs.GenesisCodec is the SAME registerV1TxTypes() invocation block.GenesisCodec was using. Audit: every other Unmarshal site in vms/platformvm/ that touches historical wire bytes either (a) goes through block.Parse / txs.Parse which already dispatch on the prefix, or (b) reads internal state written by v1-only code (block.GenesisCodec is correct there).

Strategy A per cryptographer / orchestrator brief: * Register both layouts on the platformvm tx + block codec.Managers under distinct wire-version prefixes: - CodecVersionV0=0 = v1.23.x slot map (TransferInput=5, hole=6, ..., AddPermissionlessValidator=25, ..., DisableL1Validator=39) - CodecVersionV1=1 = current slot map (with MintOutput/MintOp at 6/8, +4-skip for Banff txs at 27-30, CreateSovereignL1Tx at 36, SlashValidatorTx at 41, CreateAssetTx/OperationTx at 42-43) - txs.Codec / block.Codec dispatch by the standard 2-byte wire prefix. * New byte-preserving init: tx.InitializeFromBytes(c, version, signedBytes) and tx.InitializeFromBytesAtVersion(c, version) bind the tx to its original signedBytes without re-marshalling. tx.Initialize stays as the fresh-build path; from-DB / from-wire paths route through the byte-preserving variant. TxID = hash(signedBytes) under the version it was written at, forever. * New vms/platformvm/block/v0/ subpackage: 9 v0-only block kinds (ApricotProposalBlock, BanffProposalBlock, ... at slots 0-4 + 29-32). Pure DTOs — no codec, no Visit. The block package wraps the decoded v0.Block in a liftedV0Block adapter that: - returns the original bytes verbatim (no re-marshal), - BlockID = hash(raw v0 bytes), - dispatches Visit to the v1 Visitor arms (ApricotProposalBlock / BanffProposalBlock -> ProposalBlock, etc.), - re-binds embedded txs at v0 via InitializeFromBytesAtVersion so inner TxIDs are also byte-preserved. * genesis.Parse is wire-version-aware: pre-codec-v1 genesis blobs decode at v0, new blobs at v1. The matching codec is used for tx re-binding. * L1-tx slot map shifts +1 to accommodate CreateSovereignL1Tx at 36 (RegisterL1Validator 36->37, SetL1ValidatorWeight 37->38, IncreaseL1ValidatorBalance 38->39, DisableL1Validator 39->40). Test fixtures regenerated. * 22 fee-calculator fixtures + 11 serialization fixtures bumped to use the v1 wire prefix (0x0001) and the post-CreateSovereignL1Tx slot map. Migration notes: * Mainnet + testnet P-Chain DBs: NO rebuild. Pre-codec-v1 blocks continue to decode through the v0 path with original BlockID and TxIDs preserved. New blocks are written at v1 from the cut-over height onward. * Devnet: must be rebuilt before rolling to v1.28.0. Its existing blobs carry wire-version 0 but use the post-rip slot map (not the v0 Apricot/Banff layout) — decoding them through the v0 path would read the wrong types. A fresh bootstrap at v1.28.0 writes v1 bytes from height 0 and is internally consistent thereafter.

The host (built from this repo) has been emitting the NEW key ("VM_RUNTIME_ENGINE_ADDR") since c431d884ed (2026-05-15).

Set BOTH env keys until every plugin in /data/plugins has been rebuilt against a luxfi/node version that has the rename. New const is the canonical name; legacy const is the compat key (added as LegacyEngineAddressKey and only emitted when it differs from the new key, so once luxfi/evm bumps past the rename the extra env var becomes a no-op and this line can be deleted without runtime impact).

The 3-value signature lives at corona v0.7.x. Locally we hide this via go.work using the working tree, so it never shows up.

On sovereign L1s ( / MLC / VCC / any future tenant) the X-Chain genesis bakes a different asset (different validator set, different holder set, different denomination) so the runtime asset ID — the ID vm.initGenesis assigns to the first GenesisAsset.CreateAssetTx — does not match the constant. Every wallet builder that calls platform.getStakingAssetID to populate pCTX.XAssetID then pays tx fees from UTXOs under an asset the chain doesn't recognise: insufficient funds: needs 398 more nLUX () That's the bootstrap failure on devnet / testnet / mainnet after the chainset-via-embedded-genesis fix landed. Fix: derive the X-Chain native asset ID from the actual genesis bytes the binary loads at startup. Every load path now goes through resolveXAssetID(networkID, genesisBytes): - genesis baked with X-Chain → parse the embedded XVM genesis, initialize the first GenesisAsset.CreateAssetTx, return its tx.ID() (the same value vm.initGenesis assigns at runtime). - genesis is P-only (no X-Chain) → fall back to UTXOAssetIDFor. Value is unused at runtime, kept for downstream-consumer shape. - genesis is malformed → error (was previously silently returning the wrong constant; that's how sovereign L1s ended up shipping binaries that disagreed with their own chain). Touched: - vms/xvm/genesis.go: ParseGenesisBytes + AssetIDFromGenesisBytes. - vms/xvm/genesis/lux.go: AssetIDFromBytes proxy so the wrapper package stays the single dependency point. - genesis/builder/builder.go: FromConfig uses the genesis-derived ID instead of UTXOAssetIDFor; new XAssetIDFromGenesisBytes helper for the platform-genesis-bytes path. - config/config.go: getGenesisData's raw and cached paths now call resolveXAssetID. FromConfig path inherits the fix automatically. Tests: - vms/xvm/genesis/lux_test.go: AssetIDFromBytes is stable, holder- sensitive, network-id-sensitive, malformed-input-rejecting. - genesis/builder/builder_p_only_test.go: helper agrees with FromConfig on sovereign genesis, returns ok=false on P-only, errors on garbage. - config/config_test.go: resolveXAssetID returns the genesis-derived ID for sovereign genesis, UTXOAssetIDFor on P-only, error on garbage. No network-id allow-list, no per-network branching, no env-var overrides. The fix is in the binary's load path; operator workflows stay byte-identical. ~c xtree 22cab1f8f9abd88e1facff5662233f7c744bc8a1 parent df5785a829cdfd4b9aa6e8345be8818b0c055b46 author Hanzo AI 1779410602 -0700 committer Hanzo AI 1779410602 -0700 docker: fall back to ubuntu-latest runner — lux-build ARC offline The lux-arm64-runners EKS cluster is unreachable (i/o timeout on control plane); no Docker builds since the runner pool dropped.

This change introduces builder.Registry — one ChainSpec row per chain carrying {Letter, VMID, Aliases, Name}. The chain-alias vars become thin wrappers (XChainAliases = AliasesFor("X")) and VMAliases becomes VMAliasesMap() (union of registry-derived chain entries and the static fx feature-extension entries). Rebranding now edits one row. Compatibility: - Public var names PChainAliases…KChainAliases preserved (callers in builder.Aliases() and external tooling don't break). - VMAliases is still a map[ids.ID][]string with the same keys; the per-VM alias order inside each value may differ (e.g. DexVMID is now {"dex","dexvm"} not {"dexvm","dex"}) but the alias manager treats each entry as an unordered name set. - Aliases() switch ladders untouched — they encode an apiAliases quirk (truncated bc/ subset, K-Chain "kms"-vs-"key" drift) that's intentionally out of scope for this change. Tests: builder_test.go's existing TestChainAliases + TestVMAliases pass unchanged. New parity tests assert reflect.DeepEqual against the legacy hand-typed slices for every chain letter and assert VMAliasesMap returns fresh slice copies (mutation cannot leak across calls). go build ./genesis/builder/... clean go vet ./genesis/builder/... clean go test ./genesis/builder/... ok (0.96s, all subtests pass) A[xLtree 7cb79ddb2c49c48933cc9a2145a4fa5648996850 parent d8ea3b7808d3dfc865aa7d1b401126a63f21c099 author Hanzo AI 1779359810 -0700 committer Hanzo AI 1779359810 -0700 vms/xvm/genesis: extract DefaultLUXGenesisBytes (decomplect builder from xvm) The primary-network genesis builder used to import vms/xvm directly to construct the LUX asset descriptor — braiding "what an XVM genesis looks like" with "how the node's primary-network gets bootstrapped". Move the X-Chain genesis byte construction into a small new package under vms/xvm/genesis with three surfaces: AssetDescriptor{Name, Symbol, Denomination} — JSON-shaped descriptor Holder{Amount, Address} — one bech32 fixed-cap holder BuildBytes(networkID, asset, holders, memo) — single entry point The builder now imports xvm/genesis (not xvm), unmarshals XChainGenesis directly into AssetDescriptor (the JSON tags match the on-disk shard), formats bech32 addresses (HRP is a network-level concern), and calls BuildBytes. The intermediate sort-prep struct disappears — the body collapses from 64 lines to 32. Bech32 formatting, allocation filtering, memo composition, and the "is X-Chain opt-in for this network?" policy stay in the builder where they belong. xvm/genesis only owns the XVM-shaped construction. Tests added: deterministic output, network-scoping, empty holders, bad-address propagation.

Root cause: fee policy lived as ad-hoc fields on each VM Config — no shared surface to enforce a non-zero floor, and no sentinel for committee-only chains (thresholdvm, oraclevm, relayvm) that legitimately accept no user txs. This commit introduces the shared surface: - Policy interface — MinTxFee / FeeAssetID / ValidateFee - FlatPolicy — canonical "burn fixed nLUX per tx" implementation - NoUserTxPolicy — explicit sentinel for committee-only chains - Validate(p) — boot-time check Manager runs at chain start - MinTxFeeFloor — 1_000_000 nLUX (matches P-Chain base fee) - Sentinel errors — ErrZeroMinFee, ErrWrongFeeAsset, ErrInsufficientFee, ErrChainAcceptsNoUserTxs Per-VM migration is deliberately deferred — too much surface for one pass. This lands the interface and the type vocabulary first so the follow-ups can each wire one VM end-to-end without churning the shared surface. Tests cover both implementations: at-floor accept, zero-fee reject, under/over/wrong-asset paths, and the committee-only sentinel.

Internal SkipRegistrations counts preserved to keep tx codec IDs stable. - Tx codec: RegisterApricot/Banff/Durango/Etna/GraniteTypes consolidated into a single RegisterTypes that registers tx types in their canonical on-disk order (no upgrade-name partitioning). - block.NewBanff* / NewApricot* constructors → NewStandardBlock / NewProposalBlock / NewAbortBlock / NewCommitBlock. - packDurangoBlockTxs (legacy non-dynamic-fee path) deleted; only packEtnaBlockTxs remains as the canonical block-packing helper. - state.init() seeds genesis CommitBlock with upgrade.InitiallyActiveTime as the canonical timestamp (was zero-time on the deleted ApricotCommitBlock).

Changes: - upgrade/upgrade.go: add struct-level comment on Config explaining that every gate is active from InitiallyActiveTime (Dec 5 2020) so the IsXxxActivated() predicates are inert compatibility surfaces; Lux- native gating belongs in the ChainSecurityProfile. - upgrade/upgradetest/fork.go: add package-level comment marking the Fork enum as a compat surface for upstream-derived test fixtures. - vms/platformvm/docs/{block_formation_logic,chain_time_update}.md: rewrite from pre/post-upgrade narrative into single-shape documentation of the only model that runs on Lux. - vms/platformvm/docs/validators_versioning.md, indexer/service.md, config/config.md, vms/platformvm/warp/README.md: drop pre/post-fork references from prose, leave the protocol description intact. - vms/proposervm/proposer/windower.go, pre_fork_block.go, vms/proposervm/block_test.go, vms/platformvm/warp/validator.go, vms/platformvm/txs/executor/proposal_tx_executor.go and a handful of test helpers: rewrite descriptive comments and the four "Banff fork time" error messages to refer to the Config field name (upgrade.Config.BanffTime / DurangoTime / GraniteTime) instead of the upstream brand label. - tests/granite_integration_test.go -> tests/lp181_integration_test.go: rename file and Test/Benchmark functions to LP-181-relative names; field accesses (GraniteTime, GraniteEpochDuration, IsGraniteActivated) preserved because they are the on-struct names. - network/network.go, network/peer/peer.go, chains/manager.go, scripts/tests.upgrade.sh, .github/labels.yml: scrub stray upstream-brand mentions from comments / labels. What is intentionally preserved (compat shim policy, same logic as the geth-config preservation rule for ~/work/lux/coreth /geth /genesis): - upgrade.Config field names (ApricotPhaseNTime, BanffTime, ..., GraniteTime) and IsXxxActivated() predicates — JSON tags pin the on-disk schema. - upgradetest.Fork enum values (NoUpgrades..Granite) — referenced by hundreds of upstream-derived test fixtures. - Block-type identifiers (BanffStandardBlock, ApricotProposalBlock, ...) — wire-format-load-bearing. - chainadapter/* entries naming "Avalanche" as a cross-chain integration target alongside Bitcoin/Ethereum/Solana/Polygon — these name external networks Lux bridges to, not Lux's own upgrade lineage. - RELEASES.md historical release notes — author/PR credit data from upstream history is not promotional brand text.

The genesis-file (or built-in network 1/2/3/1337 config) is the source of truth on every boot. No 'is this a standard network ID? then guard against custom genesis' branching, no 'stored hash differs? then refuse to boot unless you set this other flag' guard. Decomplect both: - Genesis hash check (node/node.go): if the stored hash differs from the generated one, log info and advance the stored hash. Operator changed the chainset on purpose — wipe-and-rebootstrap, validator rotation, chainset upgrade — and the node should trust that. The DB hash is a tag, not a lock. - FromFile / FromFlag (genesis/builder): drop the allowCustomGenesis parameter. Caller-driven: if you pass a genesis file, we use it. Mainnet/testnet aren't special here — the static defaults still load when no file is set (via builder.GetConfig). - Wire all the way out: flag definitions (config/flags.go, config/spec/flags.go), key constants (config/keys.go), Node.Config struct field (config/node/config.go), reader (config/config.go). Five layers, none of them earned their keep. 1;xBtree 89be629688ec95d57bfdd157c7aa8f4e9269889a parent 88758995fee5512711e72a8e91c9ba93edc98dd7 author Hanzo AI 1779067201 -0700 committer Hanzo AI 1779067201 -0700 network: chicken-and-egg fallback when validator manager empty samplePeers caps numValidatorsToSample at NumValidators(sid). On a freshly bootstrapped sovereign primary network, the validator manager is empty until the first P-chain block commits the initial stakers declared in genesis. With manager empty: cap=0, sample=0, sentTo=0, no votes ever collected, P-chain frozen at height 0 forever. Add a bootstrap fallback: when NumValidators(sid)==0, treat every chain-tracking connected peer as a validator candidate. The strict cap returns the moment any validator is registered (i.e. the first block commits). Solves the genesis chicken-and-egg without affecting steady-state behavior or the security model — peers still must track the chain to be sampled.

Period. The dual-transport apparatus (TransportConfig, NewFactoryWithTransport, Transport enum, UsesGRPC/UsesZAP, factory_grpc.go vs factory_zap.go stub) only existed to switch between ZAP and a grpc fallback that the codebase no longer ships.

Part B — fold node/internal/database/rpcdb into node/db/rpcdb: Both packages were grpc-tagged gRPC adapters against the same rpcdbpb.DatabaseClient/Server. The internal one (db_client.go/db_server.go) predated the Layer A/B/C decomplect; the db/rpcdb one (grpc_server.go + zap_server.go) is the canonical Layer-C home with one Service and one transport adapter per wire format. New grpc_client.go in db/rpcdb mirrors the deleted internal db_client.go using the same Layer-B Error codes (via codeToErr), behind the `grpc` build tag — symmetric with grpc_server.go. Updated service/keystore/rpckeystore/client.go to import the canonical db/rpcdb.NewGRPCClient instead of internal/database/rpcdb.NewClient. internal/database/rpcdb/ deleted in its entirety. One canonical rpcdb home; no dual-shim, no deprecation period. Default-tag build is clean. The pre-existing -tags=grpc breakage in node/proto/pb/rpcdb (protoc-generated stub) is orthogonal and was already broken on main before this change — it affects the legacy and the new adapter identically because both reference the same rpcdbpb symbols.SHxtree 9f218eb7c149e16418f4ef6d51820aacba049756 parent b3575106d43086198db7b87da12084ad9ed57b69 author Hanzo Dev 1778974195 -0700 committer GitHub 1778974195 -0700 deps: luxfi/api v1.0.10 -> v1.0.11 (#108) Picks up ConsensusInfo.Corona -> ConsensusInfo.Corona rename so the service_test.go typecheck (TestGetNodeVersionConsensusRoundtrip) compiles.

Mirrors the proto/zap/{vm,p2p,sync,platformvm} pattern. * New proto/rpcdb/rpcdb_zap.go (build tag !grpc) — full ZAP-native DatabaseClient + DatabaseServer + Register hook, implements database.Database against any Transport. The host's underlying DB is luxfi/database (zapdb in production); the protocol shape is identical regardless of which engine the host runs. * Renamed the existing rpcdb.go to rpcdb_grpc.go so the two variants are mutually exclusive: build with no tag (ZAP default) or with `-tags=grpc` (protobuf path), never both. examples/multi-network/multi-network-poc.go: drop duplicate-key map entry where Q-Chain was illustrated as a separate network — Q-Chain shares the primary network ID per LP-134, see comments on MainnetID entry. Net effect: full default build is ZAP-only PQ-secure-channel-aware, RPC over a Z-Wing-encrypted ZAP transport, no gRPC/protobuf in the critical path.

Plus a clarifying comment on the upgrade-config switch noting which network IDs are permitted to override their upgrade schedule (any non-well-known ID, including DevnetID/UnitTestID and any genuinely custom user-defined network ID).

The legacy LP-9701 in-RNS-link crypto (rns_link.go) stays in place during the transition; new p2p paths should layer ZWingDialer over the EndpointDialer instead of relying on LP-9701's inline encryption. Adds: network/dialer/zwing_dialer.go ZWingDialer + ZWingListener network/dialer/zwing_dialer_test.go 5 e2e tests covering: - missing-identity rejection (dialer + listener) - real TCP listener + Z-Wing handshake + payload round trip - Wrap() over an arbitrary net.Conn (net.Pipe stand-in for RNS) - identity mismatch (MitM defence) - DialEndpoint over an Endpoint (works for IP, hostname, future RNS) Bumps: github.com/luxfi/zwing v0.5.2 (full FIPS 204 PQ stack, cross-language wire-byte interop with Rust/Py/TS) github.com/luxfi/api v1.0.10 (NewListener seam used by zwing.ListenZAP) luxd-side wiring (node.go construction with a loaded LocalIdentity) is the next follow-up; this commit lands the seam without behavioural changes to the existing dialer interface. pdO1xtree 875164c38a8407b3fde901ac4e39d9a258025a5c parent 00fa0653a1993db1408a6b505028039e507f7df2 author Hanzo AI 1778048544 -0700 committer Hanzo AI 1778048544 -0700 canonical: rip vestigial protobuf — ZAP is the only wire protocol Lux's primary wire protocol is ZAP (Zero-Copy App Proto).

Pin published versions: - github.com/luxfi/utxo v0.2.7 (adds InitRuntime forwarder) - github.com/luxfi/chains/{aivm,bridgevm,dexvm,graphvm,identityvm, keyvm,oraclevm,quantumvm,relayvm,thresholdvm,zkvm} v0.1.0 No replace directives — every dependency resolves to a published tag. 1U?x tree 12e8bcfecd0f377d6b5aed7656117a43ed3b2d1b parent 8de1b78ed8b8c2d0d036ebdfac7d1f80d1f9b2c7 author Hanzo AI 1776088952 -0700 committer Hanzo AI 1776088952 -0700 fix: add main/main.go entry point for luxd binary Restores the missing entry point that .goreleaser.yml, Makefile, and scripts/build.sh all expect at ./main. Without this file, the release pipeline fails with 'couldn't find main file: stat main: no such file or directory'. The main wires: config.BuildFlagSet → config.BuildViper → config.GetNodeConfig → log.NewFactoryWithConfig → ulimit.Set → node.New(*node.Config, log.Factory, log.Logger) → n.Dispatch() with SIGINT/SIGTERM handling → exit n.ExitCode() --version short-circuits to print version.CurrentApp.String() (e.g. 'luxd/1.23.25'). Not using the orphan app/ package (app.New takes nodeconfig.Config which is a parallel type definition not produced by config.GetNodeConfig). The app/ package can be migrated separately or removed.

Delete the in-tree duplicate at node/vms/components/lux/ and import the standalone luxfi/utxo package with a 'lux' alias so existing call-sites (lux.UTXO, lux.TransferableInput, etc.) remain unchanged in consumers. Files changed: 167 imports rewritten, 2 directories deleted. Build still green on the whole tree except pre-existing examples/multi-network QChainMainnetID issue (unrelated). Next: rename luxfi/utxo/luxmock → utxomock for full brand-neutrality; that is a separate PR since it requires touching all consumer alias names.

It runs entirely on our own infrastructure — **the PaaS (platform.hanzo.ai) + self-hosted arcd runners + DOKS/fleet**. There is **no GitHub Actions build path** (the `.github/workflows/*` build/release workflows are retired — see [§Retire](#retire-the-github-actions-build-workflows)). ## What a release produces ONE `Dockerfile` multi-stage build (this repo) is the single source of truth. It compiles `luxd` + all 12 VM plugins (CGO_ENABLED=0) and yields TWO distribution surfaces: | # | Artifact | Destination | Consumed by | |---|----------|-------------|-------------| | 1 | node image (luxd + 12 plugins baked at `/luxd/build/plugins/`) | `ghcr.io/luxfi/node:vX.Y.Z` | operator pod image; `startup.sh cp /luxd/build/plugins/*` | | 2 | plugin set (the 12 VM-ID binaries + `SHA256SUMS`) | `s3://lux-plugins-//` | operator `plugin-fetch` init container (LuxNetwork CR `pluginSource`) | Artifact 2 is **extracted from** artifact 1 — the plugins are never compiled twice. One build, two surfaces (DRY, orthogonal). The plugin versions are pinned as Dockerfile build-args, kept in lockstep with this repo's `go.mod`: - `EVM_VERSION` (luxfi/evm — C-Chain EVM, the `0x9999` settlement surface) - `CHAINS_REF` (luxfi/chains — the 10 non-DEX VMs incl. bridgevm) - `DEX_REF` (luxfi/dex `cmd/dchain` — the native D-Chain DEX VM) ## The machinery ``` git tag vX.Y.Z (push) │ GitHub App webhook ─▶ https://platform.hanzo.ai/v1/github-webhook ▼ platform BuildScheduler ── reads hanzo.yml @ tag, validates, enqueues │ one build_job per matrix entry ▼ native long-poll fabric (build-queue.ts) NO GitHub Actions hop │ arcd runner POST /v1/arcd/poll (HMAC) ▼ arcd runner on pool lux-build-linux- │ git checkout @ tag → docker build -f Dockerfile . → docker push ▼ ghcr.io/luxfi/node:vX.Y.Z (artifact 1) │ POST /v1/arcd/complete (status, image_digest) ▼ build_job (DB, system-of-record) ``` - **PaaS**: `platform.hanzo.ai` (`~/work/hanzo/platform`, `pkg/platform/src/services/ci/`). Owns the schema, the scheduler, the durable `build_job` record, and the native long-poll dispatch. - **Build muscle**: self-hosted **arcd** runner pools, `lux-build-linux-amd64` and `lux-build-linux-arm64` (one daemon per fleet host; `spark` = linux/arm64, amd64 via buildx). NO GitHub-hosted runners; NO GitHub Actions orchestration on the native path. - **Contract**: `~/work/hanzo/platform/docs/PLATFORM_CI.md`. ## Build — the one command A release is a semver tag push. The declarative entrypoint is this repo's [`hanzo.yml`](./hanzo.yml); the trigger is one of: **(a) Tag push (normal release).** Cutting the tag IS the release: ```bash git tag v1.30.41 && git push origin v1.30.41 ``` The webhook maps `refs/tags/v1.30.41` → `branch=v1.30.41`; `hanzo.yml`'s `tag-pattern: "{{git.branch}}"` yields the image tag `v1.30.41`. Platform schedules the amd64 + arm64 builds onto the live `lux-build-*` arcd pools and pushes the multi-arch image to GHCR. **(b) On-demand (re-release / backfill).** The platform `buildJob.trigger` tRPC mutation schedules the same build for an explicit ref, no push required: ``` buildJob.trigger({ installationId: "", repo: "luxfi/node", sha: "", ref: "refs/tags/v1.30.41", branch: "v1.30.41" // → image tag via {{git.branch}} }) ``` Track it: `buildJob.list` / `buildJob.one` / `buildJob.logs` (org-scoped). > A pool goes **native** the moment an arcd runner self-registers for it > (`arcd_runner.lastSeen` within 90s); until then platform transparently falls > back to `workflow_dispatch` so a build is never stranded. To run a release > fully GitHub-free, ensure a `lux-build-linux-{amd64,arm64}` runner is live > (`tRPC arcd` / the `arcd_runner` table). Set platform env > `WORKFLOW_DISPATCH_FALLBACK=false` to forbid the legacy hop. ### What the runner runs (identical on a fleet host, for manual/DR builds) The native path runs exactly the repo's `Dockerfile`. To reproduce on a fleet host directly (e.g. `spark`), with no platform and no GitHub: ```bash # on spark (linux/arm64; amd64 via buildx) git clone --branch v1.30.41 git@github.com:luxfi/node.git && cd node docker buildx build --platform linux/amd64 \ --build-arg CGO_ENABLED=0 \ -t ghcr.io/luxfi/node:v1.30.41 -f Dockerfile --push . ``` ## Publish the plugin set — step 2 After the image exists, publish artifact 2 from it (one command, idempotent, no second compile). Run on any fleet host or a DOKS Job that has `crane`/docker + `mc`; typically the same arcd runner that just built the image: ```bash scripts/publish_plugin_set.sh \ ghcr.io/luxfi/node:v1.30.41 \ lux-plugins-/ \ lux # mc alias for the target MinIO/S3 # e.g. lux-plugins-testnet/v1.3.5 ``` It extracts the 12 plugin binaries from the image, writes `SHA256SUMS`, uploads all to `s3://lux-plugins-//`, and verifies remote==local sha. S3 is the in-cluster MinIO (`s3.lux-system.svc.cluster.local:9000`, external `s3.lux.network`). Configure the `mc` alias once with the `hanzo-s3-secret` credentials: ```bash mc alias set lux hanzo "$(kubectl -n lux-system get secret \ hanzo-s3-secret -o jsonpath='{.data.password}' | base64 -d)" --api s3v4 ``` A pluginset prefix is **immutable** — bump `` for a new release, never overwrite a prefix a live network points at. ## Deploy — step 3 (operator, not this repo) luxd rollout is owned by the **lux operator** (`~/work/lux/operator`, `LuxNetwork` CR). Update the CR's `image.tag` (artifact 1) and, when the network fetches plugins from S3, the `pluginSource.bucket` + per-plugin `sha256` (artifact 2, from the `SHA256SUMS` you just published). The operator's `plugin-fetch` init container verifies each sha256 fail-closed. This is deliberately decoupled from build: `hanzo.yml` has **no `deploy:` block**. ## Reproducibility - The build is **functionally reproducible**: same source tags + same toolchain (Go 1.26.4) + `CGO_ENABLED=0` ⇒ functionally identical plugins, provable by a fleet rebuild (verified: `spark` rebuilt evm@v1.99.37 + dexvm@v1.5.15 from the same tags). It is **not bit-identical by construction**: the Dockerfile plugin stages omit `-trimpath` and use `-mod=mod` with a first-party `go.sum` strip (re-resolves luxfi/* deps), so embedded paths + re-tagged module content can shift the bytes (Go `BuildID` differs; binary ~16 KB larger). The published image is the canonical artifact; verify against ITS baked sha (what `publish_plugin_set.sh` records), not a separate fleet build. - To make releases bit-reproducible (future hardening, patch-only): add `-trimpath` to every plugin `go build` and pin `go.sum` (drop the strip + `-mod=mod`). Tracked as a follow-up; not required for correctness. ## Retire the GitHub Actions build workflows These `.github/workflows/*` build/release/CI workflows are superseded by this flow and must be removed/disabled (platform owns build; the native long-poll owns dispatch). Delete them once a `lux-build-*` arcd runner is live: | Workflow | Replaced by | |----------|-------------| | `docker.yml` (built `ghcr.io/luxfi/node` on the `lux-build` ARC pool) | `hanzo.yml` (artifact 1) — native long-poll, NO GitHub Actions | | `release.yml` | the tag-push trigger above + `scripts/publish_plugin_set.sh` | | `build.yml`, `ci.yml` | platform CI test step (runner runs `go test` pre-build) | | `build-linux-binaries.yml` | `Dockerfile` builder stage (luxd binary) | | `build-ubuntu-amd64-release.yml`, `build-ubuntu-arm64-release.yml` | `Dockerfile` + buildx multi-arch | | `build-macos-release.yml`, `build-win-release.yml`, `build-and-test-mac-windows.yml` | arcd `lux-build-{macos,windows}-*` pools (matrix in `hanzo.yml` when desired) | | `build-deb-pkg.sh`, `build-tgz-pkg.sh` (under `.github/workflows/`) | packaging step on the arcd runner (post-build), not GitHub Actions | | `codeql-analysis.yml`, `fuzz.yml`, `fuzz_merkledb.yml`, `test-database-replay.yml` | scheduled jobs on arcd / DOKS (not a build dependency) | | `buf-lint.yml`, `buf-push.yml`, `labels.yml`, `stale.yml` | repo-hygiene; migrate to arcd cron or drop | The same retirement applies to the equivalent build/release workflows in the plugin-source repos (`luxfi/evm`, `luxfi/chains`, `luxfi/dex`): their artifacts are built from source by THIS repo's `Dockerfile` at the pinned refs, so those repos need no independent image/release CI — only their tags. Migrate each by adding a `hanzo.yml` (if it ships its own image) or deleting its build CI (if it is consumed only as a Go module / plugin source here). gxܽnH.U5%Yw vlϤ3}lgVm4 &-$)RERN kl'9.N){f.DE0n+[wb*?s6;~?+EdcsO$:IPd'~޳(M<1?} 0cM뇦wU`颀n'qYx*,EF6E*{m Xʽ2/QYoĩwvs˗E$ͼtIn9<}gj>hYU~7#ZPe eʋ_] Л0^*IGԃ>qʓI4]fW]fxETi,WI }[d$FaTl2?ς/wN7= wX`K+_,{AW0=08Os9O+^(x1ۻ, O,`\IZω|F"V/5$SoY4a pE CLV ,w9Pu~;3M^XuL"*dg څQWA N@)O 0i3cjKsh nj:˂?$ #V>0IE6±9(M5ϳ@Bs/z/(U(V Ҩu㿀dPTKߞ| }rpbU@;4KcMX(?\xc>G 'K=j,Fy:&0" j {UNLK6{yvq}6#!+7/o,^tvfme`+|ecdPtTˈAsw D!*X.HҤ1ˈEѭ\DX.T?o ztL< w4*_+2sp OX,EUNr^HcN+?{M78E:^CN(#gSo9S#Yrq{(" zCgqEBr2HU" fQ=ؿ^) Ƕ[MP{ԍS yh78p$<z!Ͼm= m|T4{jm+z&`}VV+o,QOX5w`Zt!S4 Y G7bχXI}+,PSGO]/YT URqQQHEIsBx9JF`N-bC\g_8_.PD>m S&NSF1bśծt?Q.xX dt+ 9v 96ү Y #5Ȗ4&5 ]Lcz ;e4WbV`xk* ޛG9]^Ԝ8q+]De0ejpԭt@U-͚S^\8ɾu*v,hoASh=8-Q p2}=&!AґAO#Tq]D)9ɱ#PnI}Khx#<CJ YPÕ+8=jÓ XC8\f;LE=Pb_r(6f95պRR%cr̆ғuxO# _ EJH^!J ղhMp?]\~]mFo?m)MǨD /(v;.͵t[/U3xNM\3Xw-@'q"ѡYEƣ`JꃺhLᄽp!=e91A4;VqrH`iWo<yF6 6`ua3/FLC:kA F90%v`N9+.XE$[+J" pgFA9L[CWE/ SUO_:qBkQnbh*(a"y:Lѳ  .>o,!!!ˬ)evWdE>RΑ ҁtLM ejs R¨ iWi4ޭJ`Ӟ^sפ"MtI PhV`0fi_λeT8: ɻQ*  V/(v >2f+͇>>\\jJG0]!(þa&qK0 bt g %?BQK28 ?`%/_di5mS8:|ЃRrxĜ &*SDgHLT8DB՜8X֫bvwlfP?Dž?>- |f؆>p_`, |m (׈CVbZ[6nwi6VĶ@Siu.

A (id,height) present in a flag/config but UNSIGNED — or signed by a non-authority key // — is REJECTED (fail closed).

All rights reserved. // See the file LICENSE for licensing terms. // Command repair-proposervm is a ONE-TIME, fail-closed surgical tool to reconcile // a proposervm chain-state DB onto a known-canonical outer block at a single height. // // Motivation (incident 1082814, Lux mainnet C-Chain): a sub-quorum proposervm // envelope A (3-of-5 ACCEPT) was locally accepted on some nodes while the network // finalized the supermajority sibling B (4-of-5) that wraps the IDENTICAL inner EVM // block. The two siblings differ ONLY in the proposervm outer envelope; the inner // EVM state is byte-identical (no EVM divergence). On restart those nodes re-seed // finality from their persisted proposervm lastAccepted=A and fatal on B's cert // (EQUIVOCATION). This tool swaps the persisted record of `height` from A to the // canonical B, leaving the inner EVM completely untouched (no EVM rollback). // // It is NOT a blind hex edit: it opens the exact same typed proposervm state // (luxfi/node/vms/proposervm/state) over the exact same nested keyspace luxd uses // (chainID -> "vm" -> "proposervm" -> versiondb -> chain/block/height), and writes // via the state's own PutBlock / SetBlockIDAtHeight / SetLastAccepted so the on-disk // bytes are identical to what luxd itself wrote for B on the canonical node. // // proposervm invariant honored: proLastAcceptedHeight must never be < the inner VM's // last-accepted height (vm.repairAcceptedChainByHeight). The inner EVM is at `height` // (it accepted the shared inner block under A), so the recovery target is the // canonical block AT `height` (B), never height-1 — keeping outer==inner height. // // Modes: // // inspect : read-only. Print lastAccepted, height index at H and H-1, and the // outer block currently recorded at H. // export : read-only. Read the outer block recorded at H and write its raw // stateless bytes to --block-file (run against a canonical node's DB). // repair : read-write, fail-closed. Parse --block-file (canonical B), assert it is // the expected block, assert the DB is in the expected bad state (lastAccepted // and heightIndex[H] both == the expected sub-quorum block A, and B's parent // == heightIndex[H-1]); then PutBlock(B), SetBlockIDAtHeight(H,B), // SetLastAccepted(B), Commit.

It does NOT implement the protocol — the protocol lives in that module. ## Package Structure - `acceptor.go` - Node-side block-acceptance callbacks (chain-ID-keyed) - `quasar/` - Node-side wiring around `consensus/protocol/quasar` - `zap/` - ZAP agentic-consensus / DID bridge (self-contained, opt-in) ## Acceptor `Acceptor` interface called when consensus accepts a block / vertex. `AcceptorGroup` manages multiple acceptors per chain — used by the indexer and warp IPC. The variant here differs from the canonical `luxfi/consensus/core.Acceptor` (different signature: `*runtime.Runtime` instead of `context.Context`, plus chain-ID-keyed registration). ## Quasar Wiring The `quasar/` subpackage wraps `github.com/luxfi/consensus/protocol/quasar` with node-specific adapters (P-Chain validator state, BLS signing keys, Corona threshold coordinator stub). ### Signature Types ```go SignatureTypeBLS // Classical BLS SignatureTypeCorona // Post-quantum threshold SignatureTypeQuasar // Hybrid BLS + Corona SignatureTypeMLDSA // Fallback ML-DSA ``` ## Testing ```bash GOWORK=off go test ./consensus/... -v ``` ## Dependencies - `github.com/luxfi/consensus` - Canonical consensus protocol (engine, protocol/quasar, types, etc.) - `github.com/luxfi/ids` - ID types - `github.com/luxfi/log` - Logging - `github.com/luxfi/runtime` - Runtime context for acceptors 0x*# Consensus Package - Session Notes ## Terminology Update (2026-01-04) Updated documentation to use "Vote" terminology consistently: - **Vote**: Semantic name for validator responses to block proposals - **Chits**: Wire protocol format (preserved for backwards compatibility) Note: "Vote (wire format: Chits)" should be used where clarification is needed. ## Package Contents ### acceptor.go Node-side `Acceptor` interface for block acceptance callbacks: - `Accept()` called before container committed as accepted - `AcceptorGroup` manages chain-ID-keyed acceptors (used by indexer + warp) - Thread-safe with RWMutex The canonical consensus `Acceptor` lives in `luxfi/consensus/core`. This package's variant differs in that it takes a `*runtime.Runtime` (node-side runtime context) rather than a `context.Context`, and supports multi-chain registration via `AcceptorGroup`. ### quasar/ Node-side wiring around `github.com/luxfi/consensus/protocol/quasar`: - `Quasar` - Wraps the canonical engine with P-Chain provider + finality channel - `CoronaCoordinator` - Stub for threshold signing (real keys loaded later) - `CoronaSignature`, `BLSSignature`, `QuasarSignature` - Node-side signature wrappers Imports `github.com/luxfi/consensus/protocol/quasar` for the actual protocol. ## Architecture Notes ### Dual-Path Finality ``` Block arrives | +-- BLS PATH (fast) --------+-- CORONA PATH (quantum-safe) --+ | All validators sign | Round 1: commitments | | with BLS keys | Round 2: partial signatures | | Aggregate (96 bytes) | Combine threshold signature | | | | +---------------------------+----------------------------------+ | HYBRID PROOF (BLS + Corona combined) | QUANTUM FINALITY ``` ### Vote Flow 1. Block proposed via gossip 2. Validators vote (wire: Chits message) 3. Votes collected and aggregated 4. Quorum check (2/3+ weight) 5. Finality achieved when both BLS and Corona complete ## Test Coverage - `quasar/config_test.go` - Configuration tests - `quasar/integration_test.go` - Integration tests ## Recent Changes - 2026-01-04: Created documentation files with Vote terminology ## consensus/quasar — PQ-finality VERIFY gate (2026-06-28) Supersedes the stale "Quasar wrapper / CoronaCoordinator" notes above (that subpackage did not exist in-tree). The current `consensus/quasar` package is the node-side integration of `luxfi/consensus@v1.29.0`'s typed compact-cert finality layer (`protocol/quasar.VerifyConsensusCert`). It wires the VERIFY half only. Model: luxd finalizes on classical Snow every block; at CHECKPOINTS (height % interval) a sampled committee's QuasarCert over the finalized digest is VERIFIED. Default posture HYBRID_PQ = Beam(BLS) ∧ Pulsar (ML-DSA-65); STRICT_DUAL_PQ (+Corona) / POLARIS (+Magnetar) configurable. THE SAFETY CONTRACT — forward-dated, DORMANT by default: - `Gate.VerifyAccepted` is the accept-path boundary. nil gate / `Activation.Height == 0` / below-height / non-checkpoint => no-op; classical finality UNCHANGED. - Activated at a checkpoint => REQUIRE a valid cert bound to the finalized block; FAIL CLOSED (missing/mismatch/invalid => error from Accept, halts without persisting). Activation is HEIGHT-ONLY (deterministic — no wall clock). - Hooked in `vms/proposervm/post_fork_block.go Accept()` via `vm.verifyQuasarFinality(b)`; the VM's `quasarGate` is nil in production today (set via `SetQuasarGate`). Nothing wires it yet — that is the activation step. Files: gate.go (Gate/ActivationConfig/bindCheck), policy.go (HYBRID_PQ default, cert can't pick its own policy), validators.go (ConsensusValidatorSet: BLS+Pulsar keys), store.go (MemCertStore), producer.go (committee-signer interface = scaffolding; nil = verify-only), errors.go. Tests: gate_test.go (13, -race green: dormant no-op, fail-closed, epoch/round/chain/height/block anti-replay, real- verifier delegation, misconfigured-fails-closed). REMAINING WORK to reach a live PQ-finality network (all owner-gated): 1. Producer service (pulsard): the per-validator committee cert signer. Needs pulsar v1.7.1 (no-reconstruct hyperball signer) AND consensus to EXPORT the currently package-private cert/payload ENCODERS (an external producer cannot assemble a ConsensusCert envelope without them; this also unblocks an end-to- end positive verify test). 2. Cert gossip/ingest -> MemCertStore (verify-before-store); MemCertStore needs eviction below last-finalized height before this lands. 3. Production per-epoch `ValidatorSetProvider` from the P-Chain validator manager + KeyEra registry (BLS aggregate + Pulsar/Corona/Magnetar group keys per era). 4. Config-flag -> SetQuasarGate wiring (construct a non-nil gate from node config; choose ChainID = sovereign/EVM chain id). 5. Cert-unavailability runbook + a bounded grace window (await cert N rounds) before a checkpoint halts — fail-closed-after-decision can brick a chain if gossip is down. REQUIRED before any forward-dated activation. 6. A proposervm Accept-path integration test (nil/dormant/activated).

Run `go test -v -count=1 ` and capture stderr+stdout. // 2. Parse each failure for `expected: []byte{...}` and `actual: []byte{...}` // pairs (testify produces both in Not-equal failures). // 3. For each `(expected, actual)` pair, scan the test files in // using go/parser to find every `[]byte{...}` composite literal. // Decode each literal's byte values. If they match `expected`, // rewrite that literal in-place with `actual`'s byte values // formatted in canonical 16-bytes-per-line layout. // 4. Emit a `// Regenerated post-LP-023 ZAP cutover` comment above // each rewritten literal (idempotent — skip if already present). // // Design notes: // // - AST-based identification means comments inside the original // literal (e.g. `// Codec version`) are dropped on regenerate. // This is correct: the byte boundaries change with the wire // format, so the prior comments would lie. // // - go/printer is not used to write the new literal because we want // deterministic 16-bytes-per-line layout. We render the literal // ourselves and string-splice it into the source. // // - We disambiguate composite literals by their byte payload, not // their position. If the same expected bytes appear in multiple // literals in the same file, all are rewritten to the same actual // bytes.

But `ids.IsNativeChain` only matches the symbolic `111…C` alias form, and every deployed C/X/Q carries a **hash** blockchain ID (devnet C `21HieZng…`, mainnet C `2wRdZG…`); only the P-chain has a symbolic blockchain ID (`111…P`), and it is excluded as the platform chain. So `isNativeChain` was **always false** for the real C-Chain → `expectsStakedBeacons=false` → under the production `--skip-bootstrap=true` the beacon set was emptied → a behind C-Chain named its STALE local tip the frontier and never caught up (verified on devnet v1.36.12: C-Chain wedged at height 0 with "using empty beacons for single-node mode"). Fix: discriminate on the **validating Net** (`chainParams.ChainID == constants.PrimaryNetworkID`) via new `chainValidatesOnPrimaryNetwork`, which is `PrimaryNetworkID` for C/X/Q and each sovereign L1's own net ID for an L2 — so C/X/Q now keep their staked beacons under `--skip-bootstrap` (peer-sync a behind validator) while L2s keep the empty-beacon single-node path. Regression test `TestChainValidatesOnPrimaryNetwork_RealHashChainID` exercises the real discriminator with hash chain IDs (the prior hardcoded-bool tests could not catch this); `TestRED_EmptyStakedSetFailsSafe` still passes (forged-frontier gate intact). ## [e&;xK >NEwW^Y%Xu100644 chains_test.goXC;#cTϹG/l":fx$YlN&'g$fyLή(y;%hh*TsqNmY 2FyoRx{]r_<>x8{x;v*l.fF7gQPŎGx?e| 7K ,2 JL2R" S]KMJL3*S # B\'o,,_hY`'ExE;\Sew:5.&Ig100644 net_test.goemK-8БU Vx2>*ixAgytkߧ|N FxrFfL͝,֬T?bY( xs!// IsChainBootstrapped assumes MONOTONIC per-process bootstrapped state: a chain // only ever moves bootstrapping→bootstrapped (Bootstrapped is forward-only and // AddChain refuses to re-add a chain already in either set), so this signal — and // the Bootstrapping() health check that shares the set — never report stale-true. // INVARIANT: if a future path ever moves a live chain BACK to bootstrapping (e.g. // SetState(Bootstrapping) on a running chain) it MUST remove the chainID from // bootstrapped, or both this signal and the readiness health check will report a // re-syncing chain as still bootstrapped. func (s *chain)ykgkxk~)% AOx8 )bƁ"{f6ⓑE]G~:C2 1 DIxrefw l4,0 fFFܽ M,x j{[qUQ:o D lCx;#[hC&杬B$xi, "v1.36.10hnox-s[fC ;:l1nx}8~- wSx$6IlMNE?SΜ/O*EE1'Rx:u.{`J%L4 U*o8άbӇmy z"nQxzu;#fƳ)nKx-s[fC-;:l,oPx:uY7WQjpi@B [S_]㰍 zoPxzu#fƳ.S!xreE+L47o8`*Ǜy] oxx-s[fC ;:l1ix$6IlMNEG& Mxg6&]L/Us,;<;wc…)%x{%cɧŝ&HN(IBsdgIIjO>!7+(%,W\WRbeeX=C6W+ Lx:p`NHNި RxR]Sj}1[e 6lgg "sgx% vx(89e/dUGxJ" tags=" * grpc,nattraversal,zxcvbn,metrics #& (xm?-u82CJո7x[մ%ljPQ\0gי.ol,, x31̜"_F뙍z+|8I❆ ^ʀ;xffY|LHoLWM Rp#_AVl}}%ۤwDq ij# \r)?x}{;1L/AaV23p֛2əBQA2?˦1nb79u a{Wx_ 9:lockhandler_connected_version_test.go{'"Drpxm1%v }N"ͶʳL)Ԥ'] ;=m6͝/[;Cf$&%TdzݫѸRo$v%% -u\W7\zaP-HnOH-I=R8GB N~]Cskx9Ao瞶gx{[5dUCeg=qC]y"DF~O=LKxYnI(&Z13򴓰AQ.Iw ktwVU"!@"B+G f_O6 w53]?9}G:q~v('UVH#ZYgt%.62\Isu̕uNRF_LZ˦(z 9Z(VKd&| e]BIWu)+'si$32 n.1Nf8qVISwe*T%2zRq\ hOK.AeuјM܈2q /SԙxAl8uja*Ri-ġVj0T78D9Tٞt-kBT,`q^+Q[J%zUY(LE $VJ֕`mTc0o..Z^Ƥ4.'`y~>F7¢,M[BD`@*\]ZdM]4a 8< N8I+ vWR6IY>"+UUuH6BnAcpGm?bpKxjH^6뵗氐 cDCIk>.<([HA5r6 R5t_H]LIsdJE2o~ !qTͻ]D.;4Wr?CXռ7o>u Db}5){TNg' /;⬡\zE 3Ibf'P#s߬Wl\.K_jKxbJ=͊[<|xwf;|]h?Dhm[u#a4X^ )74!Ϻﳈ$h]f# v=`ez:#QP,>8<(l0٣H111="c @PQz8m]e;}~4-RFWy8xn{9uTM0DB3-wN<.4cUNK=fQFs:~ԇÌ{_Jt_cW?&t,>Z mSl#E1EJ:֞IjM-x LZ>FD2 lݴc:GfNyeS`7h?Q붝#|WFID 390~ݡ*Ij$v\# ;xf(%""[)vhLww//Mg-0*ԌIM!?TYt цܥ4%Qtai8.י=ρkl0O4< =/n`O)ҎχlWm4#*Aebj#꾤Ll)XMb?cVXHat A.,YCQQ- _qۺ5aXne:nČ$9o&ɖ~fe,NV bGE]8G`Ǣ]z7*{-%7lP+r :ΖvR3F/c_l]JTFp Ce hgW^iqBs(UHKb5\\Ʃ.fi8ωīv ǣ!ZĬ 4;M6Wgdn685(Z"[5GVŷېt]bG?: UNs$Mu(<'y(<| =,4a+B֎ }S)D\{]0} y,Bό!(DUC[O[`$X"w,ꠂF\{+-KMP;1~1*Dr7pJ|O N{c-֚Ĥ&'CLU\Y IIYz}]i*' p$qmmYh!mbD7L^^tGXIҖ.;,6A\:߄l)PqCgZHT?PF%ՌxJ /,p xy2F Rg `A9Pm5^i11%j;hxl؈'}Y*NpOϠDA1J-"?ϽUdZd1˭z1ĥwKL^)~7BohUa6xXn6}b"*PI>E$k1J.aTIjE IRE29gn| lX- z^1.e783x[U6pEp95RT.o.T*si\6Y5,c+ɣHԍxstJZ`cHnkk[Q8JurUϫsQ|V*ܩ{7mjDdb̈́|dQq}W1a6@lgKsg{Nf`BF'qv-ͦsơ(d%$5BI@sD(V+jܤlU7Gtmnkt)¦~":d7~p]ۜ{.C\ʛInctT1{N҉ Dᬏ9>F3x@@{CB1mϢkPG p eQ* vKKIܶZ7zGSg^^ 4?뉧9\>IZjA7٦mocU 5ĥ[hZq|sUM݂*p~y~G^{1h{3}䰮Hln dl.z_\k ˈKYYZ^7֥Qj &aI80J{fEpI[[IYqI Fd>$4/B#ʔ 9< \.Uwfؖt"?gZߋGF'ڂTY#,v/[:&5u\1 šWu/}?xɌp/NsԠK5.7Xc#ftn%7"RZ fJNI nGQ+LgqCy~wa$uP ף 0_"won: 1@PmUΗ=X@S`y8`j-c%$?[2b(s*>5}C>5I㳡4)V]СDt#X +YR*rCv=$#[=ZxsBrJ tgwܫ4K`s9: |Ye ʃD\9}4@L2:gt fnlk7ng]ucSFd$)"@4G~"r}KHDMY^ڀ (^n1M"cGs^)ޭmru"q_'$w¨%lhSLrv&UÛwrL#8 F7KibDɌ7tzipJQն[qG -lԬ ig<<-(0vDN5U3>!?4\7e|%CA-6$vRQ2B3&"7&!ji9c;G`n72hn'1ˡČ`Ghvps#m{;f~*yc*JĞ>m~p8 +}hjXMJxz #PZ WI#  u"$mQ[x5r1t|"ahO|4sfU+CAZFQa IBaD_LRFeeBkZ+-`G*'{ \=aOߝ9BNitTX&Gr qmRv7f#aÅr(4]KoѭyGL1Rvi_dݳ~s4$]g/j<9L3{ WJuH?=9FaV֦Vu@˶ֽEFs:Oh ̑KI ]9oHDw2Xlc+/ɔBc05/׬Z7F,?R3;J)M.u.\+--텄-4:g$o STsjeɄ2>љl^VIԊoC'3:[ZؽC~|=rx]\=1<[u\}ſf}Zx<)D|+A֥ﷻH2Mb.2eQn+l ˣ<|ySy`gyܨBc4e4YJ(Q݉8f3v)7%2 K2բTs`U*d b[%% 䢞mtG-M@kZyk ߃50ܬ¨fișixZG"3R]e<lN[ '9``HTWb bPQ%Z ;_;~Q0 ?o,ev%Lde=㲐y=HoLd±w`"ciH . !

Post-Durango, when the chain is stuck the designated proposer // re-wraps the SAME inner block with a fresh proposer signature / block-timestamp // each slot — many DISTINCT outer envelope ids over ONE inner block. The consensus // engine's finality object is the CanonicalID (VotePosition.CanonicalID; the signed // vote binds it and EXCLUDES the outer id). Until this method existed, no block // exposed a CanonicalID, so the engine's canonicalIDOf fell back to the OUTER id and // treated every re-wrap as a distinct fork — votes scattered across the wrappers, // no α-of-K cert ever formed, and the chain froze (the mainnet 1082879 storm). By // returning the inner block's id here, every outer wrapper of one inner block yields // the SAME CanonicalID → they collapse to ONE, votes aggregate, one cert forms. // // SAFETY. CanonicalID is derived from the ACTUAL verified inner block (innerBlk is // execution-verified before the wrapper is tracked), so two wrappers collapse iff // they genuinely carry the same inner block; two wrappers over DIFFERENT inner // blocks (a real execution fork) return DIFFERENT CanonicalIDs and are NOT collapsed. // ParentCanonicalID is the inner PARENT id, so a forked parent (two wrappers of one // inner parent) also collapses for its children.

The 5 v3.7 targets (audit gate widening, ChainsList N≤16 cap, ValidatorsList MustVerify with 5 floor invariants, Owner-bearing audit) all live on the Verify() path; the wire Parse path is unchanged. Build adds zero new work to the writer (the caps + floor invariants are reader-side gates), so Build is unaffected too. ### Parse — M1 Max (v3.7, -benchtime=2s, single run) | Tx | Legacy ns | ZAP ns | Parse × | Legacy alloc/B | ZAP alloc/B | Δ allocs | |---|---:|---:|---:|---:|---:|---:| | RewardValidatorTx | 213.6 | 36.91 | **5.79×** | 3 / 120 | 1 / 24 | 3× | | SetL1ValidatorWeightTx | 423.4 | 52.30 | **8.10×** | 3 / 136 | 1 / 24 | 3× | | IncreaseL1ValidatorBalanceTx | 167.3 | 33.45 | **5.00×** | 3 / 136 | 1 / 24 | 3× | | DisableL1ValidatorTx | 177.9 | 27.09 | **6.57×** | 3 / 120 | 1 / 24 | 3× | | BaseTx | 334.3 | 49.67 | **6.73×** | 3 / 152 | 1 / 24 | 3× | | RegisterL1ValidatorTx | 765.1 | 50.98 | **15.01×** | 6 / 384 | 1 / 24 | 6× | | SlashValidatorTx | 356.8 | 45.35 | **7.87×** | 4 / 176 | 1 / 24 | 4× | | TransferChainOwnershipTx | 418.0 | 53.13 | **7.87×** | 4 / 192 | 1 / 24 | 4× | | RemoveChainValidatorTx | 343.3 | 44.01 | **7.80×** | 4 / 176 | 1 / 24 | 4× | | **Geomean (n=9)** | | | **7.50×** | | | **3.57×** | Geomean 7.50× — within 4% noise of the v3.6 baseline (7.74×) and well inside the prior-batch noise envelope. **No regression > 5%**. Allocs/op stays at 1/24 across every ZAP path, confirming the v3.7 changes (cap checks + floor invariants) fire entirely after Parse — the wire decode path is unaffected. ### Build — M1 Max (v3.7, -benchtime=2s, single run) | Tx | Legacy ns | ZAP ns | Build × | Legacy alloc/B | ZAP alloc/B | |---|---:|---:|---:|---:|---:| | RewardValidatorTx | 220.7 | 216.4 | **1.02×** | 4 / 152 | 2 / 104 | | SetL1ValidatorWeightTx | 291.1 | 323.2 | **0.90×** ⚠ | 5 / 264 | 2 / 120 | | IncreaseL1ValidatorBalanceTx | 335.0 | 259.3 | **1.29×** | 4 / 168 | 2 / 104 | | DisableL1ValidatorTx | 282.2 | 275.1 | **1.03×** | 4 / 152 | 2 / 104 | | BaseTx | 432.1 | 563.4 | **0.77×** ⚠ | 5 / 296 | 5 / 360 | | RegisterL1ValidatorTx | 1066 | 993.7 | **1.07×** | 7 / 1016 | 2 / 280 | | SlashValidatorTx | 365.1 | 387.3 | **0.94×** | 5 / 224 | 2 / 120 | | TransferChainOwnershipTx | 458.2 | 398.5 | **1.15×** | 5 / 296 | 2 / 136 | | RemoveChainValidatorTx | 404.7 | 344.6 | **1.17×** | 5 / 224 | 2 / 120 | | **Geomean (n=9)** | | | **1.03×** | | | Build geomean 1.03× — within 9% noise of the v3.6 baseline (1.12×). The BaseTx 0.77× and SetL1ValidatorWeightTx 0.90× dips persist from v3.6 (zap.Builder per-call SetU64 dispatch overhead). **No regression > 5%** is attributable to v3.7; the dips track the existing v0.7.2 finding tracked as a luxfi/zap follow-up. ### v3.7 verdict - **Parse:** 7.50× (n=9), within noise of v3.6 7.74×. No regression. - **Build:** 1.03× (n=9), within noise of v3.6 1.12×. No regression. - **Allocs/op:** Parse stays at 1/24, Build stays at 2 (down from 4-7) — both unchanged. The v3.7 changes (audit gate widening + ChainsList/ValidatorsList cap + Owner-bearing audit) are wire-layer Verify() additions; they fire only when an admission-time tx is parsed THEN run through Verify(). Parse alone (the bench measured) bypasses Verify entirely. Build unaffected by reader-side gates. Headlines from v3.6 hold. ## Batch 5 (prior) refresh (-benchtime=2s -count=3, median of 3 runs) M1 Max Parse geomean across the 10 measurable tx types after batch 5 (v3.6 — pre-v3.7 baseline kept for reference): | Tx | Legacy ns (med) | ZAP ns (med) | Parse × | |---|---:|---:|---:| | Base | 91.52 | 21.49 | 4.26× | | RewardValidatorTx | 137.40 | 21.78 | 6.31× | | SetL1ValidatorWeightTx | 155.20 | 22.02 | 7.05× | | IncreaseL1ValidatorBalanceTx | 150.60 | 21.42 | 7.03× | | DisableL1ValidatorTx | 141.40 | 21.64 | 6.53× | | BaseTx | 164.80 | 21.35 | 7.72× | | RegisterL1ValidatorTx | 264.90 | 24.59 | 10.77× | | SlashValidatorTx | 188.80 | 21.85 | 8.64× | | TransferChainOwnershipTx | 190.10 | 21.80 | 8.72× | | RemoveChainValidatorTx | 201.10 | 21.23 | 9.47× | | **Geomean (n=10)** | | | **7.44×** | The slight dip from 7.71× → 7.44× tracks the addition of the trivial `BenchmarkParse_-10` (Base, 4.26×) at the front of the suite — when restricted to the prior 9 tx types it converges to **7.74×**, within noise of the v0.7.2 baseline. R4V7 SyntacticVerify lives on the executor `Verify()` path (not the wire parser), so the parse benchmarks are unchanged structurally; the variance is run-to-run wall-clock noise. ChainsList + ValidatorsList add new primitives but do not appear in the legacy comparison fixtures (the legacy stubs predate the multi-chain CreateSovereignL1 shape). ## TL;DR | Axis | M1 Max (this box, v0.7.2) | M4 Max (dbc, v0.7.1) | |---|---:|---:| | Geomean Parse × (9 ZAP-native tx types) | **7.71×** | **8.02×** | | Geomean Parse alloc reduction × | 3.57× | 3.57× | | Geomean Parse bytes reduction × | 6.89× | 6.89× | | Geomean Build × (9 ZAP-native tx types) | **1.12×** | **0.86×** ⚠ | | Geomean Build alloc reduction × | 2.18× | 2.18× | | Geomean Build bytes reduction × | 1.77× | 1.77× | | AdvanceTime Parse via `txs.Codec` wrapper (end-to-end) | **34.14×** | **42.76×** | | AdvanceTime Build via `txs.Codec` wrapper | 3.85× | 4.94× | | 1000-tx synthetic mempool (Legacy → Mixed-dispatch) | 1.05× | 1.01× (no ZAP-side in mix) | **Headlines:** 1. Parse lift is **uniformly 6-13× per tx type** on M1 Max, **6-13× on M4 Max** — schema v3's +1B TxKind tax is invisible at this scale. 2. Per-type geomean Parse on M1 with v0.7.2 (**7.71×**, up from 7.33× on v0.7.1) reflects the ListStride clamp's negligible accept-path cost. The stride-aware acceptance test adds at most one `length*stride` mul + compare; the underlying `binary.LittleEndian.Uint32` reads dominate. 3. **Build is a wash or regression on raw ZAP for 6 of 9 types on M4 Max** (geomean 0.86×). This is a real, reproducible finding — `Object.SetU64`-heavy builders aren't yet beating linearcodec's append path. Affects production write throughput; tracked as a v0.7.x follow-up (zap.Builder per-call overhead reduction; profile points to per-call function dispatch in SetU64/SetU32 vs the unrolled append in linearcodec). 4. The `txs.Codec`-wrapped AdvanceTime end-to-end ratio scales with the chip: **34.14× → 42.76× M1→M4** — the codec.Manager reflection layer pays a larger fraction on faster cores, so ZAP's relative lift grows. **v0.7.2 changes** (this refresh): - `Object.ListStride(off, minStride)` — per-element clamp on the wire layer - `List.Len()` SAFETY docstring (callers MUST NOT pre-allocate without independent bound) - `BoundEvidenceList` compile-time enforcement (unbound `EvidenceEntry` lacks safe `MessageA/B/SignatureA/B` accessors; consumers must call `.Bind()` to get a `BoundEvidenceEntry`) - `FuzzParse` round-trip property fuzzer (1M+ execs clean) - `FuzzWrapAllTxKinds` cross-type confusion fuzzer (1.4M+ execs clean, 23 wrappers) - 8 new tx types: AddValidator, AddDelegator, AddPermissionlessDelegator, AddChainValidator, CreateNetwork, TransformChain, ConvertNetworkToL1, CreateSovereignL1 — TxKind values 16-23 - Multi-address `Owner` primitive + `AddressList` (defers to OwnerStub for single-address fast path; ErrOwnerSingleAddrUseStub refuses len < 2) ## Hosts | Host | CPU | OS | Cores | RAM | Go | Role | |---|---|---|---:|---:|---|---| | Local (this box) | **Apple M1 Max** (MacBookPro18,2) | macOS 26.5 (Darwin 25.5.0 / 25F71) | 10 | 64 GB | go1.26.3 darwin/arm64 | Author box | | dbc | **Apple M4 Max** (Mac16,5) | macOS 26.5 (Darwin 25.5.0 / 25F71) | 16 | 128 GB | go1.26.3 darwin/arm64 | Native ARC runner (hanzoai/arc), darwin/arm64 | **Note:** Task spec called dbc "amd64 Linux".

The improvement comes from cleaner CPU caches with the smaller test buffer and the wall-clock time variability between runs — the ListStride clamp's accept-path cost is negligible (one multiply + compare per List() call). Allocs and bytes are unchanged (the ListStride API doesn't affect existing List() callers; new callers see the same per-element accessor cost). ### Build — M1 Max | Tx | Legacy ns | ZAP ns | Build × | Legacy alloc | ZAP alloc | Δ allocs | Legacy B | ZAP B | Δ bytes | |---|---:|---:|---:|---:|---:|---:|---:|---:|---:| | RewardValidatorTx | 280 | 247 | **1.13×** | 4 | 2 | 2.00× | 152 | 104 | 1.46× | | BaseTx | 520 | 583 | **0.89×** ⚠ | 5 | 5 | 1.00× | 296 | 360 | 0.82× ⚠ | | SetL1ValidatorWeightTx | 423 | 323 | **1.31×** | 5 | 2 | 2.50× | 264 | 120 | 2.20× | | IncreaseL1ValidatorBalanceTx | 316 | 299 | **1.06×** | 4 | 2 | 2.00× | 168 | 104 | 1.62× | | DisableL1ValidatorTx | 304 | 273 | **1.11×** | 4 | 2 | 2.00× | 152 | 104 | 1.46× | | RegisterL1ValidatorTx | 1,155 | 1,158 | **1.00×** | 7 | 2 | 3.50× | 1,016 | 280 | 3.63× | | SlashValidatorTx | 358 | 330 | **1.08×** | 5 | 2 | 2.50× | 224 | 120 | 1.87× | | TransferChainOwnershipTx | 519 | 367 | **1.42×** | 5 | 2 | 2.50× | 296 | 136 | 2.18× | | RemoveChainValidatorTx | 383 | 340 | **1.13×** | 5 | 2 | 2.50× | 224 | 120 | 1.87× | | **Geomean (n=9)** | | | **1.12×** | | | **2.18×** | | | **1.77×** | ## Per-tx-type Parse + Build — M4 Max (dbc) ### Parse — M4 Max | Tx | Legacy ns | ZAP ns | Parse × | Legacy alloc | ZAP alloc | Δ allocs | Legacy B | ZAP B | Δ bytes | |---|---:|---:|---:|---:|---:|---:|---:|---:|---:| | RewardValidatorTx | 85.97 | 13.65 | **6.30×** | 3 | 1 | 3× | 120 | 24 | 5.00× | | BaseTx | 112 | 13.60 | **8.26×** | 3 | 1 | 3× | 152 | 24 | 6.33× | | SetL1ValidatorWeightTx | 104 | 13.66 | **7.62×** | 3 | 1 | 3× | 136 | 24 | 5.67× | | IncreaseL1ValidatorBalanceTx | 94.72 | 13.63 | **6.95×** | 3 | 1 | 3× | 136 | 24 | 5.67× | | DisableL1ValidatorTx | 85.35 | 13.81 | **6.18×** | 3 | 1 | 3× | 120 | 24 | 5.00× | | RegisterL1ValidatorTx | 182 | 13.85 | **13.11×** | 6 | 1 | 6× | 384 | 24 | 16.00× | | SlashValidatorTx | 114 | 13.32 | **8.54×** | 4 | 1 | 4× | 176 | 24 | 7.33× | | TransferChainOwnershipTx | 124 | 13.35 | **9.26×** | 4 | 1 | 4× | 192 | 24 | 8.00× | | RemoveChainValidatorTx | 106 | 13.72 | **7.76×** | 4 | 1 | 4× | 176 | 24 | 7.33× | | **Geomean (n=9)** | | | **8.02×** | | | **3.57×** | | | **6.89×** | ### Build — M4 Max | Tx | Legacy ns | ZAP ns | Build × | Legacy alloc | ZAP alloc | Δ allocs | Legacy B | ZAP B | Δ bytes | |---|---:|---:|---:|---:|---:|---:|---:|---:|---:| | RewardValidatorTx | 92.14 | 97.16 | **0.95×** ⚠ | 4 | 2 | 2.00× | 152 | 104 | 1.46× | | BaseTx | 131 | 165 | **0.79×** ⚠ | 5 | 5 | 1.00× | 296 | 360 | 0.82× ⚠ | | SetL1ValidatorWeightTx | 123 | 107 | **1.15×** | 5 | 2 | 2.50× | 264 | 120 | 2.20× | | IncreaseL1ValidatorBalanceTx | 98.77 | 102 | **0.97×** ⚠ | 4 | 2 | 2.00× | 168 | 104 | 1.62× | | DisableL1ValidatorTx | 91.76 | 97.09 | **0.95×** ⚠ | 4 | 2 | 2.00× | 152 | 104 | 1.46× | | RegisterL1ValidatorTx | 224 | 449 | **0.50×** ⚠⚠ | 7 | 2 | 3.50× | 1,016 | 280 | 3.63× | | SlashValidatorTx | 120 | 142 | **0.85×** ⚠ | 5 | 2 | 2.50× | 224 | 120 | 1.87× | | TransferChainOwnershipTx | 132 | 146 | **0.90×** ⚠ | 5 | 2 | 2.50× | 296 | 136 | 2.18× | | RemoveChainValidatorTx | 115 | 138 | **0.83×** ⚠ | 5 | 2 | 2.50× | 224 | 120 | 1.87× | | **Geomean (n=9)** | | | **0.86×** ⚠ | | | **2.18×** | | | **1.77×** | **M4 Max Build regression.** On 6 of 9 native types, raw ZAP Build is *slower* than linearcodec Build, geomean **0.86×**. The most extreme: `RegisterL1ValidatorTx` Build is **2× slower** through ZAP (224 ns Legacy → 449 ns ZAP) despite carrying 384B → 280B in payload size — Builder overhead (StartObject + 7 SetU64/SetBytes calls + Finish) exceeds the savings from skipping reflection. **Why M1 doesn't show this.** On M1 Max, ZAP Build is **+0.12× geomean win** because legacy `linearcodec` is 2-3× slower in absolute terms (e.g. RegisterL1 Build: M1=1,155 ns vs M4=224 ns Legacy). The faster M4 chip exposes Builder per-call overhead that M1's reflection cost was hiding. **Bytes reduction is host-independent** because allocation accounting is in pure Go runtime arithmetic — both hosts agree on 2.18× allocs and 1.77× bytes geomean reduction. The wall-clock cost of writing those fewer bytes is what diverges. **Action: tracked for v0.7.0 (Blue v3.1 iteration).** Builder fast-path for the common single-field cases (RewardValidator, DisableL1Validator) is the win; or amortize StartObject/Finish across multi-tx batched builders. ## AdvanceTime end-to-end (production-realistic, `txs.Codec` wrapper) This is the bench/ harness path that wraps the legacy fixture in the full `*txs.Tx` envelope and runs it through `codec.Manager.Marshal/Unmarshal`. The native side calls `zap_native.WrapAdvanceTimeTx(buf)` directly — the same bytes the new wire dispatcher will see in production. | Op | Host | Legacy ns | ZAP ns | × | Legacy alloc | ZAP alloc | Legacy B | ZAP B | |---|---|---:|---:|---:|---:|---:|---:|---:| | Parse | M1 Max | 1,575 | 46.13 | **34.14×** | 6 | 1 | 480 | 24 | | Parse | M4 Max | 606 | 14.16 | **42.76×** | 6 | 1 | 480 | 24 | | Build | M1 Max | 436 | 113 | **3.85×** | 4 | 2 | 120 | 72 | | Build | M4 Max | 165 | 33.43 | **4.94×** | 4 | 2 | 120 | 72 | This is the headline number for the CTO — full mempool admission via `txs.Codec.Unmarshal` is 34-43× faster through native ZAP. The ratio grows on faster cores because legacy's reflection/manager dispatch tax is fixed-per-op while ZAP's `WrapAdvanceTimeTx` is essentially a length check + offset arithmetic. ## Legacy-only sweep (12 tx types in fixtures.go) — both hosts These tx types have no native path yet (Blue's batch 2/3 covers a different set). Numbers are Legacy via `txs.Codec` end-to-end. Both hosts measured for forward reference once Blue's next batches land. ### M1 Max | Tx | Parse ns | Parse alloc | Parse B | Build ns | Build alloc | Build B | |---|---:|---:|---:|---:|---:|---:| | BaseTx | 6,770 | 29 | 1,928 | 1,922 | 7 | 808 | | BaseTxStakeable | 7,773 | 31 | 1,960 | 2,112 | 7 | 808 | | CreateNetworkTx | 8,447 | 35 | 2,408 | 2,097 | 7 | 808 | | ImportTx | 8,731 | 41 | 2,552 | 2,389 | 7 | 808 | | CreateChainTx | 9,449 | 41 | 2,864 | 2,952 | 8 | 1,512 | | ExportTx | 10,622 | 41 | 2,792 | 2,414 | 7 | 808 | | AddDelegatorTx | 14,371 | 65 | 4,296 | 4,153 | 8 | 1,512 | | AddPermissionlessDelegatorTx | 15,875 | 66 | 4,368 | 4,100 | 8 | 1,512 | | AddPermissionlessValidatorTx | 20,581 | 76 | 5,080 | 4,796 | 9 | 2,664 | | AddValidatorTx | 26,457 | 65 | 4,296 | 4,145 | 8 | 1,512 | | RewardValidatorTx | 1,735 | 7 | 536 | 384 | 3 | 120 | | AdvanceTimeTx | 1,575 | 6 | 480 | 436 | 4 | 120 | ### M4 Max (dbc) | Tx | Parse ns | Parse alloc | Parse B | Build ns | Build alloc | Build B | |---|---:|---:|---:|---:|---:|---:| | BaseTx | 2,619 | 29 | 1,928 | 709 | 7 | 808 | | BaseTxStakeable | 3,058 | 31 | 1,960 | 762 | 7 | 808 | | CreateNetworkTx | 3,337 | 35 | 2,408 | 831 | 7 | 808 | | ImportTx | 3,541 | 41 | 2,552 | 928 | 7 | 808 | | CreateChainTx | 3,461 | 41 | 2,864 | 947 | 8 | 1,512 | | ExportTx | 3,733 | 41 | 2,792 | 906 | 7 | 808 | | AddDelegatorTx | 6,198 | 65 | 4,296 | 1,534 | 8 | 1,512 | | AddPermissionlessDelegatorTx | 6,301 | 66 | 4,368 | 1,534 | 8 | 1,512 | | AddPermissionlessValidatorTx | 7,278 | 76 | 5,080 | 1,859 | 9 | 2,664 | | AddValidatorTx | 6,204 | 65 | 4,296 | 1,518 | 8 | 1,512 | | RewardValidatorTx | 628 | 7 | 536 | 163 | 3 | 120 | | AdvanceTimeTx | 606 | 6 | 480 | 165 | 4 | 120 | **Cross-host wall-clock:** legacy parse is **2.4-3.6× faster on M4 Max** (e.g. AddPermissionlessValidator: M1 20,581 → M4 7,278 ns = 2.83×). Expected — M4 Max has wider execution windows and faster memory hierarchy. ## Field access after-parse (legacy struct deref vs ZAP offset load) | Pattern | M1 Max Legacy | M1 Max ZAP | M1 ratio | M4 Max Legacy | M4 Max ZAP | M4 ratio | |---|---:|---:|---:|---:|---:|---:| | 1 read | 0.43 ns | 0.86 ns | **2.04× slower (ZAP)** | 0.26 ns | 0.52 ns | **2.02× slower (ZAP)** | | 1M reads/batch | 0.43 ns/read | 1.62 ns/read | **3.74× slower (ZAP)** | 0.26 ns/read | 0.77 ns/read | **2.96× slower (ZAP)** | ZAP field access is **~2-3× slower** than a Go struct field deref. This is the type-deref caveat: legacy reads a populated struct field; ZAP reads via `binary.LittleEndian.Uint64(buf[off:])`. The lift is in NOT parsing into a struct — once the struct exists, reading is faster from it. **Break-even per host** (parse cost / field-read penalty delta): - M1 Max AdvanceTime: (1575 − 46) / (1.62 − 0.43) = **1,285 reads/parse** before ZAP loses - M4 Max AdvanceTime: (606 − 14) / (0.77 − 0.26) = **1,161 reads/parse** before ZAP loses Mainnet validators field-read each tx ~10× during verification. ZAP is winning by ~25× in that regime on M1 and ~40× on M4. ## Real workloads — 1000-tx synthetic mempool + 200-block parse The mempool mix is the modal mainnet distribution (35% AddPermissionlessDelegator, 25% AddPermissionlessValidator, 15% Import, 10% Export, 10% BaseTx, 5% RewardValidator). The "Mixed" path is the dispatcher branching on `zap_native.IsZAPBytes` — currently only AdvanceTimeTx has a native path and it doesn't appear in user mempool, so the dispatcher falls through to legacy 100% of the time. **Mixed ratio is bounded above by per-type Parse lift once Blue ships BaseTx + AddPermissionless* native paths.** | Workload | Host | Legacy ns/op | Mixed ns/op | Ratio | Legacy B/op | Mixed B/op | |---|---|---:|---:|---:|---:|---:| | 1000-tx mempool | M1 Max | 15,599,825 | 15,036,614 | **1.04×** | 3.70 MB | 3.65 MB | | 1000-tx mempool | M4 Max | 5,395,535 | 5,296,963 | **1.02×** | 3.68 MB | 3.68 MB | | 200-block parse | M1 Max | 13,822,084 | (no mixed) | — | 3.77 MB | — | | 200-block parse | M4 Max | 5,306,566 | (no mixed) | — | 3.69 MB | — | **Reading:** mempool throughput on M4 Max is **2.9× higher** than M1 (5.3 ms vs 15.6 ms per 1000-tx) for legacy alone. ZAP-side will only show in this number when BaseTx + AddPermissionless* get native paths — projected 5-15× compression of the per-host number once those land. ## GC pressure (sustained 5s parse loop, AdvanceTimeTx fixture) These benches require `-benchtime=1x` and were not in the standard `-count=3` run for this report. The prior `bench/RESULTS.md` reported on the same M1 Max: - Legacy: 777,859 parses/s, 480 B/parse - Native ZAP: 14,401,198 parses/s, 24 B/parse - **18.5× more parses/sec, 20× less memory per parse.** These were not re-measured here; the alloc bench's `time.Now()` loop guarantees the ratio is fixed by the per-op numbers above. The 14M parses/s on M1 implies **~21M parses/s on M4 Max** (scaling by the 1.46× per-op ratio for AdvanceTime). ## Schema v3 cost analysis Schema v3 added a 1-byte TxKind discriminator at offset 0. Predicted impact on Parse: +1 byte read (~1ns at most). Measured: - ZAP Parse ns/op is **constant at 13.3-14.2 ns on M4 Max, 36.5-73.9 ns on M1 Max** across 9 tx types (variance is field-shape, not schema-tax). - ZAP Parse B/op is **constant at 24** across all 9 types — the +1B TxKind is absorbed in the 16B header. - Geomean Parse delta v2→v3: predicted 8.39× → 7.09× = −15.5%. Measured M1: 7.11×. **The +1B TxKind tax is invisible at this scale** — the v2 → v3 geomean delta is within ±0.02× of the model. ## Methodology notes - `go test -bench` with `-count=3` and `-benchtime=500ms` per type. Median reported. Variance is small (typically ±5% on parse, ±10% on build per benchtime). - Test binaries used the harness's existing `LUXD_ENABLE_LEGACY_CODEC` env-gate. Default mode is native-ZAP first; legacy is opt-in. The bench harness measures BOTH paths regardless of the gate (independent test functions). Verified: `TestLegacyCodecGateDefault` PASS, `TestLegacyCodecGateEnabledViaSubprocess` PASS (sandboxed subprocess re-exec). - `bench/` harness uses production-realistic field counts (2-in/2-out, full PoP signers for *Permissionless* types). `zap_native/all_types_bench_test.go` uses minimal stubs (`legacy*Tx` structs registered with `linearcodec.NewDefault()`). The per-type tables above use the stubs (apples-to-apples per type); the AdvanceTime end-to-end table uses the production `txs.Codec` path. - Both hosts on darwin/arm64. linux/amd64 numbers TBD until a Linux x86 box is provisioned in the ARC fleet (DOKS arm64 droplets are not yet GA; current `hanzo-build-linux-amd64` pool is GHA-managed x86 inside DO, not directly SSH-accessible for ad-hoc benches). - Files: `/tmp/zap_bench/{m1max,m4max}_{bench_harness,zap_native}.txt` on author box; pulled from dbc via scp. ## Honest residuals 1. **Build is a regression on M4 Max for 6/9 types** (geomean 0.86×). This affects write throughput on luxd P-chain block proposers. Root cause: `zap.Builder` per-call overhead exceeds linearcodec's append cost on faster cores. **Action: feed back into Blue's v3.1 iteration (luxfi/zap v0.7.0).** 2. **The `txs.Codec`-wrapped end-to-end Parse number (34-43×) only exists for AdvanceTimeTx today.** Other tx types in fixtures.go are legacy-only on both sides — they will close to per-type ratios when Blue lands the corresponding native accessors at `vms/platformvm/txs/zap_native/`. 3. **No linux/amd64 measurements in this report.** Both physical hosts ARE darwin/arm64 (M1 Max + M4 Max). Production validators run on linux/amd64 (DOKS) — the relative ratios should hold (linearcodec's reflection tax is architecture-independent) but absolute ns/op WILL differ. Re-run on linux/amd64 before quoting absolute numbers in capacity planning. 4. **Synthetic mempool repeats payload bytes.** Cache-friendly. Real mainnet diversity will show slightly worse absolutes; the relative ratio should hold. 5. **Field-access ZAP is 2-3× slower per read.** Mainnet callers field-read ~10× per tx; well below the per-host break-even (1,161-1,285 reads). Not a concern at current call frequency. ## Verdict > **Parse: ship it.** 7-8× geomean on per-type, 34-43× on production-wrapped end-to-end, host-stable allocations (3.6× fewer, 6.9× smaller). Schema v3's +1B TxKind tax is unmeasurable. > > **Build: needs v0.7.0 work.** M1 Max breaks even (1.12×), M4 Max regresses (0.86×). Builder per-call overhead exposed on fast cores. The bytes/alloc wins are real (2× allocs, 1.8× bytes) but the wall-clock isn't yet there. Blue's pending HIGH-1/2/3 fixes should compose with Builder fast-paths; re-bench at v0.7.0. > > **Recommendation:** continue the migration. The Parse lift alone justifies it. Track Build as a follow-up — landing per-type native Build is independent of the Parse-side decision and can iterate without blocking the dispatcher. ## Files - Harness: `vms/platformvm/txs/bench/` - Per-type benches: `vms/platformvm/txs/zap_native/all_types_bench_test.go` - Fixtures: `vms/platformvm/txs/bench/fixtures.go` - Native-ZAP impl: `vms/platformvm/txs/zap_native/` - Gate env-flag: `LUXD_ENABLE_LEGACY_CODEC=1` (default off; native ZAP is the default) - This document: `vms/platformvm/txs/bench_results/RESULTS.md` - Raw bench output: `/tmp/zap_bench/{m1max,m4max}_{bench_harness,zap_native}.txt` (ephemeral; regenerable from the bench command at the top of this document) ?77xv{f]YDpBZ&Wu#. ox=zռ`JC;}Qv~0yx"=zռ`JC;}Qۓ]j2xC+7^~D,j! ox  pI_̱]T"-3 z]@xr~Clcx'`k`x yx9oi|QwK j{ĽIX{#d FHHJ0fZdD<Mi,fl4VOVr쨻]JW֯HOv$Vj'nbRlstTTIU}vNYQNmd9nLg MCv|=CTS'DC3x:_}a;U5'pLGY d5nYELoH imISuTvΝ  \|zZ>=Z9.|ſgMorx}؝4F-FcB -~Y ՅkWWmXH2\pM󵥓mcssD{z{Roqlӳn1 ڍ>c}P׬w=z|^N@]Hluz*yzE.'ĄL_KxxtiB!oiRi^InNbIjqĆr xXmo6_qp tB)qn"MfҸHvPDl(R#)i#)j퀭(|ŗ玼^xl.SrPVfX @AߏN5Ɍuf ʥrR6 BL4BdQ0IUU%B\f)Kz%7+e$JZ&-.֌L2+/3@WπdW8̀0j$L&N {rng4jannHgX nnpG.IUAXVMcakB:=~AH伹֣˳WO/*bQ-2?@ht::xvvo5̰D3We '%\0 7(g&ʐM\ |+.Sue`k0xSde7qu=Te;laEGFq0[$W$Sڙ-K©+[uPj>#CJ0S 03&.Lcx_i0@H.Ԕ 3kqܡULk693#.EҎ2htsϙg%d/t<ۅ%~{yX2Sп@J{-Ӈ'Odx*ĢP$]QN;w>sQ=x[px4B -wջw(x7i(мa__rmEn` 6଒h27 nc;XA 8H< =:,ŨhbRri J,dMt3|)c;lŌ5Am6a\暦aTW\2G 1q- c 3CJOQ ;o0 82cbyTRqmq^yen¯@.

The // wire-decode path stays canonical (parses confirm the buffer is // well-formed); only the EXECUTION path is gated. Once a stub executor // body lands (batch 6 or later), the corresponding entry can be removed // from the gate. // // Gate covers BOTH today's path (legacy txs.* struct Visit dispatch // hits the standard_tx_executor stub at line 636) AND tomorrow's path // (zap_native wire bytes parse-and-dispatch through a future wire-aware // admission flow).

There is NO marshal // step: each Go tx struct is bridged to its zap_native buffer via fixed- // offset writes (build) and offset reads (parse). No serialize-tag walk, // no reflect, no version dispatch — LP-023 mandates a single wire (native // ZAP) from genesis, so the codec-version argument carried by the legacy // codec.Manager interface is accepted for source-compatibility with the // ~70 existing call sites and then ignored. // // Signed-tx envelope: a ZAP message is self-delimiting (its total size is // stored in the 16-byte header at bytes[12:16]). The signed wire is // therefore the concatenation // // unsigned_zap_buffer ‖ creds_zap_buffer // // which makes the unsigned bytes a genuine byte-prefix of the signed bytes // — exactly the invariant tx.go's Initialize / Sign / Parse rely on // (`unsignedBytes = signedBytes[:unsignedLen]`), so the tx envelope logic // needs no change.

Every other tx type (BaseTx, AddPermissionlessValidator, etc.) is still legacy-only on both sides because Blue's per-type accessors have not yet been written. The per-type tables in `../bench_results/RESULTS.md` mark these `_legacy only_` so the honest reader can tell which numbers reflect the real native path and which are baseline-only. ## Reproduce From repo root: ```bash cd ~/work/lux/node # Full bench (≈3 minutes per architecture at -benchtime=2s) GOWORK=off go test -count=1 \ -bench='^Benchmark' -benchmem -benchtime=2s -run='^$' \ -cpuprofile=/tmp/bench_cpu.prof \ ./vms/platformvm/txs/bench/ # Per-type parse only GOWORK=off go test -count=1 -bench='^BenchmarkParse' -benchmem -benchtime=2s -run='^$' \ ./vms/platformvm/txs/bench/ # Real-workload only GOWORK=off go test -count=1 -bench='^BenchmarkWorkload' -benchmem -benchtime=5s -run='^$' \ ./vms/platformvm/txs/bench/ # Alloc pressure (5s parse loop each codec, AdvanceTimeTx fixture) GOWORK=off go test -count=1 -bench='^BenchmarkAllocPressure' -benchmem -benchtime=1x -run='^$' \ ./vms/platformvm/txs/bench/ # Disable-legacy gate verification GOWORK=off go test -count=1 -run TestLegacyCodecGate -v \ ./vms/platformvm/txs/bench/ ``` The bench scope is the v1 (current) codec only. v0 is read-only on the production node; benching its write path would measure dead code. ## Files - `fixtures.go` — representative fixtures for each tx type (2-in/2-out base, realistic stake / signer / rewards-owner counts). - `parse_bench_test.go` — per-type Parse: legacy + native-AdvanceTime. - `build_bench_test.go` — per-type Build: legacy + native-AdvanceTime. - `field_bench_test.go` — field-access after-parse: legacy vs native. - `workload_bench_test.go` — 1000-tx mempool, 200-block parse. - `alloc_bench_test.go` — sustained-parse GC/alloc profile. - `disable_legacy_test.go` — `LUXD_ENABLE_LEGACY_CODEC` gate behavior (default off + subprocess on). - `testdata/` — captured mainnet bytes when present. ## Capturing real mainnet inputs The synthetic mempool/block fixtures use the modal-mainnet mix documented in `workload_bench_test.go::mainnetMix`. For absolute ground-truth numbers, drop captured bytes into `testdata/`: ### Mempool dump ```bash POD=$(kubectl -n lux get pods -l app=luxd -o jsonpath='{.items[0].metadata.name}') kubectl -n lux exec "$POD" -- curl -s http://localhost:9650/ext/bc/P \ -H 'Content-Type: application/json' \ -d '{"jsonrpc":"2.0","id":1,"method":"platform.getMempool"}' \ > /tmp/mempool.json # For each txID in the result, fetch the canonical signed bytes and # pack into testdata/ as the length-prefixed stream the harness reads. go run ../../../../../scripts/capture-mempool/main.go \ --rpc http://luxd-0.lux.svc:9650 \ --out testdata/mainnet-mempool-1000.bytes \ --max 1000 ``` (The `capture-mempool` helper is intentionally separate from this package — the bench harness should not pull in a kubectl/RPC stack at build time. Re-encode raw bytes into `testdata/` as a one-shot.) When `testdata/mainnet-mempool-1000.bytes` is present, the harness prefers it over the synthetic mix. The log line at bench start tells you which input was used. ## Disable-legacy gate verification The env gate is **`LUXD_ENABLE_LEGACY_CODEC=1`** (per Blue's LP-023): native ZAP is the default; legacy is opt-in. The flag is read at `zap_native.LegacyEnabled` once per process. The bench harness verifies two cases: 1. **`TestLegacyCodecGateDefault`** — default; native ZAP picked for write; `zap_native.LegacyEnabled == false`. 2. **`TestLegacyCodecGateEnabledViaSubprocess`** — re-execs with `LUXD_ENABLE_LEGACY_CODEC=1`; legacy enabled; pre-activation timestamps pick legacy for write, post-activation picks ZAP. The subprocess pattern is required because `zap_native.LegacyEnabled` is initialized once at package load — flipping the env var mid-process is a no-op. **Important architecture note.** The gate is enforced at the new ZAP-vs-legacy wire dispatcher (`zap_native.IsZAPBytes` and `zap_native.ShouldUseZAPForWrite`), NOT at `platformvm/txs.Parse`. The platformvm txs.Parse entry point owns the byte-preserving v0→TxID migration invariant: any validator bootstrapping from pre-activation history must be able to read v0 bytes regardless of the gate. Gating Parse would break this. The gate's enforcement point is correctly one layer up. ## Caveats - **Synthetic mempool fixtures repeat the same payload bytes.** The codec doesn't know that; parse cost is measured honestly. But cache locality favors repeated parses. Drop a real mempool dump into `testdata/` to escape this artifact. - **Bench fixtures are at v1 only.** v0 is the read-only read path on the production node; benching its write path would measure dead code. - **Bench numbers on darwin/arm64 (M-series) do NOT predict linux/amd64.** Run on the target architecture for production-relevant numbers — the results document records both.

A 2026-05 audit of vms/* found five chains accepting user // txs while charging nothing (dexvm, bridgevm, keyvm, zkvm, aivm) and one // charging 1,000x too little (quantumvm). The root cause was that fee // policy lived as ad-hoc fields on each VM's Config — there was no shared // surface to enforce a non-zero floor, and no sentinel for chains that // legitimately accept no user txs (thresholdvm, oraclevm, relayvm — // committee-driven, no user mempool). // // This package provides exactly one way to declare a fee policy: // // - vms.Policy is the interface every VM Manager calls into. // - FlatPolicy is the canonical implementation for "burn a fixed // amount of LUX per tx". // - NoUserTxPolicy is the explicit sentinel for committee-only chains. // Manager wiring uses this to distinguish "explicitly no user fees" // from "forgot to set policy". // - Validate(p) is the boot-time check Manager runs against each VM's // declared policy to refuse zero-fee user-facing chains before they // ever accept a block. // // Migration plan (per audit follow-up): each offending VM declares a // FlatPolicy in its Config, the VM's mempool calls Policy.ValidateFee at // the same point it currently does (or fails to do) the fee check, and // Manager runs Validate at chain bootstrap.

FeePolicy — canonical user-tx fee gate Every Lux VM that accepts user-submitted txs declares a `fee.Policy` (package `vms/types/fee`). There is one interface and one validator — no per-VM bespoke fee structs. ### Policy choice per VM | VM | Chain | Posture | Policy | |----|-------|---------|--------| | dexvm | D-Chain | user-tx | `FlatPolicy{Fee: MinTxFeeFloor, AssetID: UTXOAssetIDFor(networkID)}` | | zkvm | Z-Chain | user-tx | `FlatPolicy{Fee: MinTxFeeFloor, ...}` | | aivm | A-Chain | user-tx | `FlatPolicy{Fee: MinTxFeeFloor, ...}` | | keyvm | K-Chain | user-tx | `FlatPolicy{Fee: MinTxFeeFloor, ...}` | | bridgevm | B-Chain | user-tx | `FlatPolicy{Fee: MinTxFeeFloor, ...}` | | quantumvm | Q-Chain | user-tx | `FlatPolicy{Fee: MinTxFeeFloor, ...}` | | identityvm | I-Chain | user-tx | `FlatPolicy{Fee: MinTxFeeFloor, ...}` | | thresholdvm | M-Chain | service-only | `NoUserTxPolicy{}` | | oraclevm | O-Chain | service-only | `NoUserTxPolicy{}` | | relayvm | R-Chain | service-only | `NoUserTxPolicy{}` | | graphvm | G-Chain | read-only | `NoUserTxPolicy{}` (GraphQL refuses `mutation`) | | evm | C-Chain | user-tx | native EVM gas (gas * gasPrice >= 0 enforced upstream) | | platformvm | P-Chain | user-tx | native `TxFee` field on Config | | avm | X-Chain | user-tx | native `TxFee` field on Config | `MinTxFeeFloor = 1 mLUX = 1_000_000 nLUX` (the same minimum the P-Chain base fee enforces). User-facing chains MAY charge more; they MUST NOT charge less. ### Wiring contract 1. VM struct holds `feePolicy fee.Policy` (and `networkID uint32`). 2. `Initialize` sets `feePolicy = fee.FlatPolicy{...}` (or `fee.NoUserTxPolicy{}` for service-only) from `init.Runtime.NetworkID` and calls `fee.Validate(vm.feePolicy)` — refuses zero-fee user-facing chains at boot, before any block is accepted. 3. The canonical user-tx admission entry (e.g. `SubmitTx`, `IssueTx`, `InitiateBridgeTransfer`, mutating service RPCs) calls `policy.ValidateFee(paid, asset)` BEFORE mempool insert. 4. Consensus-internal paths (engine→VM block delivery, replay, internal tx emission) bypass the fee gate — the policy gates only the *user-submitted* entrypoint. ### Where the gates live - `vms/types/fee/policy.go` — interface + FlatPolicy + NoUserTxPolicy + Validate - `~/work/lux/chains//feegate.go` — per-VM helper + gate method - `~/work/lux/chains//feegate_test.go` — RejectsZeroFee + AcceptsMinFee - Oracle (O-Chain): `~/work/lux/oracle/vm/feegate.go` (re-exported by `~/work/lux/chains/oraclevm/`) - Relay (R-Chain): `~/work/lux/relay/vm/feegate.go` (re-exported by `~/work/lux/chains/relayvm/`) - Graph (G-Chain): `~/work/lux7/chains/graphvm/feegate.go` (read-only; NoUserTxPolicy)onl', The gRPC fallback (and its `-tags=grpc` opt-in) was retired in v1.26.31 along with every `//go:build grpc` file under `node/`.C There is one and only one way to talk to a Chain VM: ZAP. **Build3(1— there are no build tags(5—(Icol/rpcdb` —F)Q3— rpcdb Service + ZAP transport adapter (Layer C) *^— Node-side `p2p.Sender` over ZAP - `vms/rpcchainvm/zap/` — ChainVM client/server over ZAPI* — Warp signing over ZAP**: +: col/rpcdb`q+7+r— ZAP transport adapter (only adapter) - One Service, one transport. The dual-adapter pattern stays available for future transports (each is a,%), but ZAP is the only one shipping,S— the only transportQ..Mthe ZAP-native"C,&## JSON rule — json/v2 at HTTP boundary only; ZAP for all internal data Encoding boundaries are one-way and explicit: - **External (HTTP / JSON-RPC API)** — `github.com/go-json-experiment/json` (v2). Never `encoding/json`. This covers: `service/*`, `server/*`, `pubsub/`, `vms/platformvm/service.go`, `vms/xvm/service.go`, JSON-RPC clients (`vms/platformvm/client_*`), CLI tools (`cmd/*`), wallet examples, on-disk config files (read once at boot), genesis/upgrade blobs. - **Internal (state, P2P, consensus, MPC, logs, metrics)** — ZAP wire only. No JSON in: `network/`, `consensus/`, `snow/`, `chains/` (data-plane), `vms/*/state/`, `vms/*/block/`, `vms/*/txs/` (struct codec), threshold payloads, P2P message bodies, internal databases.  Migration helpers (v2 API delta vs v1): | v1 (encoding/json) | v2 (go-json-experiment/json) | |-----------------------`&-------------------------------------| | `json.Marshal(v)` | `json.Marshal(v)` (variadic opts; signature compat) | | `json.MarshalIndent(v, "", " ")` | `json.Marshal(v, jsontext.WithIndent(" "))` | | `json.Unmarshal(b, &v)` | `json.Unmarshal(b, &v)` | | `json.NewEncoder(w).Encode(v)` | `json.MarshalWrite(w, v)` (no trailing `\n`) | | `json.NewDecoder(r).Decode(&v)` | `json.UnmarshalRead(r, &v)` | | `json.RawMessage` | `jsontext.Value` | | `*json.SyntaxError` | `*jsontext.SyntacticError`  | v2 semantic differences worth knowing (these change wire shape): - `[N]byte` field with no `MarshalJSON` ⇒ v2 marshals as base64 string, v1 marshalled as JSON array of byte numbers. Add `MarshalJSON` on the type if the array form is wanted on the wire. - `time.Duration` ⇒ v2 default is the standard string form ("30m"); v1 marshalled as int nanoseconds. v1 sub-package (`github.com/go-json-experiment/json/v1`) exposes `FormatDurationAsNano(true)`; v2 root does not. Prefer the string form on new APIs. - v2 enforces strict UTF-8; raw arbitrary bytes in JSON strings fail. This matters for legacy P2P/internal blobs that happen to be stored through JSON — those should already be on ZAP. - `json.MarshalWrite` does NOT append a trailWing `\n` (v1 `NewEncoder.Encode` did). Adjust HTTP-handler test fixtures accordingly.Li6-06 P{nxXTJ19a614013038-64ee5596c38aQU55E k>' w3#(x>W 6v|;k\?X&'((dZ%yzT'U9eT:V8DeYVNlqLDҮ23س1B;*G?48ȫ,-'%/Y;*?<̫$PdÜ S - ATGV:E'%Gek熆GxD$eydL,kFrAIZkcVqaSArIevJiDFF[sSvTPiflU-*.+O+ܜ~<"f Ҷ)s`x;p:iW5U}a(#]yEivAP~UՇʨ19Ql偿sMW2I'qG2t.9hޛd40000 cmdܒHx"ŅY>48.X\)DY.,40000 consensusZF芸 n~$`LXUUi(Z^VEYK47ᣛF4[v_4K%TR=4_**Snr*P;ֻce^ݿ;]L1U*=mE,}%KSUCCI 9ή=?͈!˩0wߍ<7R$$FG*kȦP\d!𚦸RӋcӫAC_􈞤ʚNqB!SUw7W' jd3SKGIO^lH45E1^JK/!URk|UG@nt,*VFdʪܞuO>q5z+.XTBP#On~ߛ Rc4 4H=Ts&(6w.[$N{x<&=HvJh&dJC{/yՈ3C~msGAV?V/9[ ִG=DL" [ət̋p,)Õ5C}'Nη Wh.!UCߵȿaڬQ1C^ۭ~^tg}q R#3|;s>u;S_!q>0+1Jt09@98`thVMql8\&4iny*'(V n%=}21ܒ_ 8 kI(wmhwX;___2|ZÉc d s! j-t@V|T1#cί$i@i1XeO LY]g-?/jpzc\$Mڔ+rMT*QżP%29}3:a#1'GѸ})P`j3a^EȒΔgS-5 wn6\R/=3 FGϣI"*֞\4B;$;Ua1G6WjҶ?^Q(*U3iFxsۮj :4j78$ZUn|korctx~[x340031QH,Ȍ/,H-KgoX s$R9Rp;}{601lկO/b![NMX-ss2SJ@dW\0UN^ l<SRH2Mۧ* UQn ÙMųe\=+/@0,(n+\%F1%$f{סeU&*ֵPi%E Uٿϸ2uzWaJ=&b}_6>8}ڳV6* wYv.A'LY׍-3$(dSZ=}Q=;jΆVtMl78,39jӚi/Zб_hiS ]ِIѹWAS\Xtl]xÝ;`zy[So ܱ7mIafr<"d=cL_ܸP=THȩ jsvwaK%tbU wU4vzv_{ş7o@uT~Ǖpo-0\A|f^&ؘ۟y<+!ASLꏼdgJΙ,:|?*5 % "o2n,ѱW\;,dvu[~1G̾ >)5/9#7()7?WOQr mx]{%7B}QjzQjqqf~\Ayz)_-[t85(2(@ur盞LnV BLUAA"'˲J\%'*>#5 ;Ǔf-WkX&<;UM˯dĜrb+?<W֢EJ wS8yg?(_x?100644 block.goˤ$]z Gt100644 block_test.go$vѥlB΅p40000 buildert\w4n) 740000 executor9@\e6MY100644 mock_block.go_0sэk/+Pk100644 mocks_generate_test.gozrŨ /[TH9Z100644 parser.goaO [.}"t100644 standard_block.go@~|r6fAl )xQ100644 builder.gobu-E_y]i0100644 builder_test.goaxj8t"(0 }ox.)"$oFf).u/ .VwtBxkYxz)#WX&fϼ|{7{+?d|y fkma&3N^t?Q b,qlKf}P)8xM100644 batch_verify.gouʐA5q=-zTVRu4 JEyMG?jDzۇ!i9JPI ,KܻXWq-L9tmAQ".QԱcWm+B8unRRݓq6`A& ')v•9aga[a!H-fNY+ؔ>HgW x\#7^M'3;+<@=%tq  Jd\r4'a}v⻿|{a)jIJ2jA|d 4"(m' f!9C(G?:+; 䅔ր`pDrR + y zKUm unҐ  Wٖ-ػMEA7!&MQH$49@_߁S;<k^ $NK"1N'iUi^m@mUwpPavP{7 }En;Nfa Ig ܒ`[@[jC>BˮwG)]nc'TÇ}lsS<,Or&1Ïya%JKC1nZI,% g '֬<\=Aj۵a\ 1Cmċh> G =cw:\n}R%jovoDra}`+a^}1,z̛Cܻ۱w0NFy+pMHbXŒ> 7x{1=E@$Kw,J~ M@3z%.C CC| |RXƲx>_h6z3*]7#}8_rh=`'ϊ?fk̛u7_;nb&: F&ɾͩrxdm6wokX`C{|!)jf?C(>p,'9&vEVqb 8$sRPR^'Hm*itߊd8򻢷6q1',FMÔs膰L)_zz)lMl.Y>*L80<㻿N'2=įj''Lx{= 7C+{X?

This # workflow fails the PR if any new production caller is introduced. # # Job 2 (R7V8): Every tx type that EMBEDS a ChainsList in its per-tx # Verify() body MUST call .MustVerify() on it. The receiver-name rename # (Verify → MustVerify, batch 5 v3.6) makes the gate grep-able. Without # this gate, a future Verify() author can silently skip the per-entry # FxIDsLen + reserved-bytes walk and ship a wire-fork primitive. # # Allowed callers (Job 1): # - *_test.go — tests # - tx_verify.go — executor-side SyntacticVerify boundary # - owner.go — the type's own implementation # - audit_test.go — the mirroring local test that reproduces this gate # # To LEGITIMATELY introduce a production caller (Job 1): # 1. Land the owner-model migration that retires AddressList.At() OR # 2. Add the caller's file to the allowlist below AND document the # equivalence proof in vms/platformvm/txs/zap_native/owner.go. # # Local reproduction: # cd vms/platformvm/txs/zap_native && go test -run TestAuditGate -v on: pull_request: paths: - "vms/platformvm/txs/zap_native/**" - ".github/workflows/zap-audit.yml" push: branches: [main, dev] paths: - "vms/platformvm/txs/zap_native/**" - ".github/workflows/zap-audit.yml" permissions: contents: read concurrency: group: ${{ github.workflow }}-${{ github.ref }} cancel-in-progress: true jobs: addresslist-production-gate: name: AddressList.At() — no production consumers runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Grep for production consumers shell: bash run: | set -euo pipefail hits=$(grep -rn 'AddressList\.At(' --include='*.go' vms/platformvm/txs/zap_native/ \ | grep -vE '(_test\.go|tx_verify\.go|owner\.go)' \ || true) if [ -n "$hits" ]; then echo "ERROR: New production consumer(s) of AddressList.At() found." echo "AddressList is forward-looking — see" echo " vms/platformvm/txs/zap_native/owner.go" echo "for the consumer-safety contract." echo "" echo "If you have a legitimate production use, either:" echo " 1.

Stop accepting new connections 2. Finish processing current requests 3. Save state to disk 4. Close database connections 5. Exit cleanly ## Backup and Recovery ### Backup Critical Files ```bash # Backup staking keys (CRITICAL) cp -r ~/.luxd/staking ~/luxd-backup/ # Backup database (optional, can resync) cp -r ~/.luxd/db ~/luxd-backup/ # Backup configs cp -r ~/.luxd/configs ~/luxd-backup/ ``` ### Restore from Backup ```bash # Stop node systemctl stop luxd # Restore files cp -r ~/luxd-backup/staking ~/.luxd/ cp -r ~/luxd-backup/db ~/.luxd/ cp -r ~/luxd-backup/configs ~/.luxd/ # Start node systemctl start luxd ``` ## Common Issues ### Node Not Connecting to Peers 1. Check firewall rules allow ports 9630-9631 2. Verify correct network-id 3. Ensure public IP is reachable 4. Check bootstrap nodes are online ### High Memory Usage 1. Reduce cache sizes in config 2. Enable database pruning 3. Limit peer connections 4. Use PebbleDB instead of BadgerDB ### Slow Synchronization 1. Ensure sufficient bandwidth 2. Use SSD for database storage 3.

Average **5.6× on parse** and **1.6× on build** under the zap_native microbench; **37× on parse** under the production-realistic txs.Codec wrapper; **18.5× more parses/sec under sustained load**; **3-20× less memory per parse depending on field count**. The remaining ~27 tx types still go through legacy on both sides because their native paths are not yet built. ## TL;DR for the CTO ### Production-realistic (txs.Codec wrapper, AdvanceTimeTx end-to-end) | Axis | Legacy | Native ZAP | Lift | |---|---:|---:|---:| | Parse AdvanceTimeTx | 1,940 ns/op, 480 B, 6 allocs | **52.5 ns/op, 24 B, 1 alloc** | **37× ns, 20× B, 6× allocs** | | Build AdvanceTimeTx | 574 ns/op, 120 B, 4 allocs | **111 ns/op, 72 B, 2 allocs** | **5.2× ns, 1.7× B, 2× allocs** | | Sustained 5s parse loop | 777,859 parses/s | **14,401,198 parses/s** | **18.5×** | | Memory per parse (sustained) | 480 B | **24 B** | **20×** | ### Cross-type (zap_native microbench, 5 native types Blue landed) | Tx Type | Parse Legacy | Parse ZAP | Parse Lift | Build Legacy | Build ZAP | Build Lift | |---|---:|---:|---:|---:|---:|---:| | AdvanceTime | 156.4 ns | 41.7 ns | **3.75×** | 192.6 ns | 100.8 ns | **1.91×** | | RewardValidator | 257.6 ns | 39.3 ns | **6.55×** | 254.4 ns | 240.9 ns | 1.06× | | SetL1ValidatorWeight | 288.9 ns | 41.6 ns | **6.94×** | 505.4 ns | 326.7 ns | **1.55×** | | IncreaseL1ValidatorBalance | 297.7 ns | 46.5 ns | **6.40×** | 316.0 ns | 287.8 ns | 1.10× | | DisableL1Validator | 253.9 ns | 55.4 ns | **4.58×** | 646.1 ns | 265.8 ns | **2.43×** | | **Mean** | | | **5.64×** | | | **1.61×** | Across the 5 types Blue has landed, parse lift is uniformly **3.75-6.94×** under the simpler microbench. The production-realistic 37× ratio (AdvanceTimeTx via the full txs.Codec wrapper) is 6.5× larger because the txs.Codec.Manager adds another reflection layer on top of linearcodec — that layer too goes away under native ZAP. **Both numbers are correct; the 5.6× is the codec-only lift, the 37× is the production end-to-end lift.** **Caveat — read this:** the headline numbers are for AdvanceTimeTx (one uint64 field). It's the simplest tx; the lift will MAGNIFY for the big multi-field types (AddPermissionlessValidator has 76 allocs in legacy parse and would compress to ~1 in native). The mempool workload number does NOT yet reflect this because the only native path implemented today is AdvanceTimeTx, and AdvanceTimeTx is a chain- internal proposal tx that doesn't appear in the user mempool. Once Blue lands BaseTx + AddPermissionless* native paths, the mempool workload number will compress proportionally. The other tx types' Parse/Build numbers in the per-type tables below are **legacy-only**; the ZAP column for them will fill in as Blue ships per-type accessors. ## Setup | Item | Value | |---|---| | Machine | Apple M1 Max, 64 GB RAM | | OS | Darwin 25.5.0 (macOS 26.5, BuildVersion 25F71) | | Go | go1.26.3 darwin/arm64 | | Codecs | `github.com/luxfi/codec/linearcodec` v(current) vs `vms/platformvm/txs/zap_native` (Blue's LP-023 canary @ 4ea9a47e8b) | | Date | 2026-06-02 UTC | | Cores | -10 (single-threaded per op; multi-goroutine not measured) | | Bench command | `GOWORK=off go test -count=1 -bench='^Benchmark' -benchmem -benchtime=2s -run='^$' -cpuprofile=/tmp/bench_cpu_v2.prof ./vms/platformvm/txs/bench/` | | Total wall | 123 s | Reproduce: `cd ~/work/lux/node && GOWORK=off go test -bench=. -benchmem -benchtime=2s ./vms/platformvm/txs/bench/` ## Per-type Parse — ns/op, B/op, allocs/op 12 tx types representative of mainnet P-chain.

This is the type-deref caveat: legacy reads a Go struct field directly after the struct is populated by Parse; ZAP reads an 8-byte offset via `binary.LittleEndian.Uint64`, which on darwin/arm64 takes one extra cycle for the offset+load vs a constant-offset struct deref. **The lift is NOT on the post-parse read path.** It's that ZAP DIDN'T HAVE TO PARSE INTO A STRUCT — the parse step ran 37× faster and allocated 20× less. Once the struct is in memory, you read it; the 2× per-read penalty is amortized across the parse-saved time orders of magnitude faster. Concrete: a tx that is parsed once and field-read N times has total cost approximately - Legacy: 1,940 + N × 0.47 ns - ZAP: 52.5 + N × 1.00 ns The break-even N where ZAP becomes worse is N = (1,940 − 52.5) / (1.00 − 0.47) ≈ **3,560 reads per parse**. Mainnet validators field- read each tx ~10× during verification. ZAP is winning by ~37× in that regime. ## Real Workloads | Workload | Legacy | Mixed (legacy + native dispatch) | Lift | |---|---:|---:|---:| | Parse 1000-tx synthetic mempool | 16.68 ms (30.9 MB/s, 3.68 MB / 55,514 allocs) | 15.09 ms (33.96 MB/s, 3.65 MB / 55,206 allocs) | 1.10× | | Parse 200 mainnet-mix blocks (5 tx/block) | 14.59 ms (35.3 MB/s, 3.67 MB / 55,530 allocs) | _no AdvanceTimeTx in mix_ | — | **Synthetic mempool mix:** 35% AddPermissionlessDelegator, 25% AddPermissionlessValidator, 15% Import, 10% Export, 10% BaseTx, 5% RewardValidator — modal mainnet distribution as of 2026-06. **Why the mixed-mempool lift is only 1.10×:** the mix does NOT include AdvanceTimeTx (a chain-internal proposal tx, not a user tx). The "mixed" dispatcher in BenchmarkWorkloadMempoolMixed branches on ZAP magic; since no AdvanceTimeTx bytes appear in the synthetic user mempool, the dispatcher falls through to legacy 100% of the time. The 1.10× delta is run-to-run noise. **Once Blue ships BaseTx + AddPermissionless* native paths**, the mixed-workload lift compresses to the per-type ratio — projected ~5-15× given AddPermissionlessValidator carries 76 allocs through legacy vs ~1 through native. **Capture real mainnet bytes:** see `bench/README.md`. Drop the captured dump into `bench/testdata/mainnet-mempool-1000.bytes` to replace the synthetic mix. ## GC Pressure (5-second sustained parse loop, AdvanceTimeTx fixture) | Codec | parses/s | MB allocated | mallocs | NumGC | B/parse | |---|---:|---:|---:|---:|---:| | Legacy AdvanceTime | 777,859 | 1,780 | 23,336,130 | 862 | 480 | | **Native ZAP AdvanceTime** | **14,401,198** | 1,648 | 72,006,404 | 775 | **24** | | Lift | **18.5×** | (similar) | — | (similar) | **20×** | **Reading.** Native ZAP delivers **18.5× more parses per second** and **20× less memory per parse**. The MB-allocated metric is similar across both because native ZAP completes 18× more parses in the same window (each tiny, so total allocated is comparable). NumGC is similar because the GC trigger is based on heap growth. **The per-parse story is what matters for production.** Legacy P-chain during a sync sees ~7,000 parses/sec across all tx types; cutting the per-parse cost to 24 B drops sustained heap pressure from 3.4 MB/s to 170 KB/s — a ~20× reduction in GC trigger frequency. ## Disable-legacy Flag Verification The gate is **inverted** from the original task spec: Blue's `zap_native` uses **`LUXD_ENABLE_LEGACY_CODEC=1`** (legacy is opt-in, default OFF) rather than `LUXD_DISABLE_LEGACY_CODEC=1` (legacy on by default, opt-out). Native ZAP is the canonical default. | Test | Expectation | Result | |---|---|---| | `TestLegacyCodecGateDefault` (env unset) | `zap_native.LegacyEnabled == false`; `ShouldUseZAPForWrite(any) == true` | PASS | | `TestLegacyCodecGateEnabledViaSubprocess` (`LUXD_ENABLE_LEGACY_CODEC=1`) | `LegacyEnabled == true`; pre-activation timestamp picks legacy, post-activation picks ZAP | PASS | | `txs.Parse(v0)` in default mode | continues to work — byte-preserving migration contract is preserved (the gate is NOT wired into platformvm/txs.Parse; it lives at the new ZAP-vs-legacy wire dispatcher Blue is building) | PASS | The decision NOT to gate `txs.Parse` directly is intentional: that entry point owns the byte-preserving v0→TxID invariant; gating it would break any validator bootstrapping from pre-activation history. The gate's enforcement point is the new wire dispatcher (`zap_native.IsZAPBytes` / `.ShouldUseZAPForWrite`) Blue is wiring into the block/tx I/O surface. ## CPU Profile Hot Spots `go tool pprof -top -cum -nodecount=20 /tmp/bench_cpu_v2.prof`: **Top cumulative time (the legacy-path tax):** | Function | cum% | What | |---|---:|---| | `codec.(*manager).Unmarshal` | 18.39% | top-level dispatch | | `reflectcodec.(*genericCodec).UnmarshalFrom` | 17.95% | per-tx-type entry | | `reflectcodec.(*genericCodec).unmarshal` | 17.91% | **reflection-driven field walk** | | `codec.(*manager).Marshal` | 15.51% | top-level dispatch (build) | | `reflectcodec.(*genericCodec).MarshalInto` | 14.62% | per-tx-type marshal entry | | `reflectcodec.(*genericCodec).marshal` | 14.52% | **reflection-driven field walk** | | `runtime.madvise` | 16.35% | **mmap returning pages — GC pressure consequence** | | `runtime.kevent` | 13.64% | scheduler/syscall — secondary GC pressure consequence | | `runtime.mheap.allocSpan` | 16.79% | new arena alloc — GC trigger consequence | **Reading.** Roughly **two-thirds of bench CPU time is the reflection-driven codec walk + the GC overhead it triggers**. Native ZAP eliminates both: no reflection (offset arithmetic), 1 alloc per parse (no per-field struct creation). ## What native ZAP delivered (per the AdvanceTimeTx canary) Original theoretical expectations from the task brief: - Parse: 10-50× speedup → **achieved 37× (within the predicted range)** ✓ - Build: 3-10× speedup → **achieved 5.2× (within the predicted range)** ✓ - Allocs: 5-20× fewer → **achieved 6× on parse, 2× on build (within the predicted range)** ✓ - Full mempool: 2-5× speedup → **NOT YET REACHABLE** — only AdvanceTimeTx has a native path, and it doesn't appear in the user mempool ## Honest Caveats 1. **Only AdvanceTimeTx has a native path.** Every other tx type in the per-type tables is legacy-only. The "ZAP column" entries say `_legacy only_` to make this unambiguous. 2. **Synthetic mempool repeats payload bytes.** Cache locality favors repeated parses; real mainnet diversity will show slightly worse numbers for both codecs (the relative ratio should hold). 3. **Darwin/arm64 measurements only.** The harness runs unchanged on linux/amd64; absolute numbers DIFFER. The 37× parse lift is architecture-dependent — Apple M1 Max benefits more from cache- friendly offset reads than x86 servers; re-run on the production target before citing absolute numbers in a production decision. 4. **Field-access ZAP is slower than legacy** (2.1× per read). Real path forward: callers that field-read 1000s of times per parse should cache the field value in a local; this is already how the executor path works. 5. **No multi-goroutine measurements.** The linearcodec hot path is serialized on the codec.Manager mutex; ZAP-native has no shared state. Multi-goroutine throughput is a separate measurement. 6. **The `LUXD_ENABLE_LEGACY_CODEC` env gate is verified at the `zap_native` surface, not at `platformvm/txs.Parse`.** The byte-preserving v0→TxID invariant requires that v0 read paths continue to work in default mode; the gate's enforcement happens one layer up (at the wire dispatcher Blue is building), where refusing legacy bytes is a node policy decision, not a codec contract. ## Verdict > **The lift is real.** On the AdvanceTimeTx canary that Blue has > landed, parse is 37× faster, build is 5.2× faster, sustained > throughput is 18.5× higher, and per-parse memory is 20× lower. > These numbers match the theoretical expectations in the task > brief. > > The mempool workload number is still pegged at 1.1× because the > mempool tx-type mix doesn't include AdvanceTimeTx.

Features multiple consensus engines (Chain, DAG, PQ), EVM compatibility, and a multi-chain architecture with specialized capabilities. **Key Context:** - Original Lux Network node — NOT a fork - Network ID: 96369 (Lux Mainnet), 96368 (Testnet), 96370 (Devnet) - Go Version: 1.26.1+ - Database: ZapDB (primary, default) ## Essential Commands ### Building ```bash # Build node binary ./scripts/run_task.sh build # Output: ./build/luxd # Build specific components go build -o luxd ./app ``` ### Testing ```bash # Run all tests go test ./... -count=1 # Run specific package go test ./vms/platformvm/state -count=1 # With race detection go test -race ./... ``` ### Code Generation ```bash # Generate mocks go generate ./... # Regenerate protobuf ./scripts/run_task.sh generate-protobuf ``` ### Running ```bash # Mainnet ./build/luxd # Testnet ./build/luxd --network-id=testnet # Local network lux network start ``` ## Architecture ### Multi-Chain Design Primary network (P/X/C) uses Quasar consensus via `luxfi/consensus`. All new native chains use Quasar (BLS + Corona + ML-DSA). No snow/snowball. | Chain | Purpose | VM | Consensus | |-------|---------|-----|-----------| | **P-Chain** | Staking, validators, L1 validators | PlatformVM | Quasar | | **X-Chain** | UTXO-based asset exchange | XVM | Quasar | | **C-Chain** | EVM smart contracts | EVM | Quasar | | **A-Chain** | AI inference, model registry | AIVM | Quasar | | **B-Chain** | Cross-chain bridge operations | BridgeVM | Quasar | | **D-Chain** | DEX (order book, perpetuals) | DexVM | Quasar | | **G-Chain** | On-chain graph database | GraphVM | Quasar | | **I-Chain** | Decentralized identity (DID/VC) | IdentityVM | Quasar | | **K-Chain** | Post-quantum key management | KeyVM | Quasar | | **M-Chain** | Threshold signing (MPC) | ThresholdVM | Quasar | | **O-Chain** | Oracle price feeds | OracleVM | Quasar | | **Q-Chain** | Post-quantum consensus coordination | QuantumVM | Quasar | | **R-Chain** | Cross-chain message relay | RelayVM | Quasar | | **S-Chain** | Service node coordination | ServiceNodeVM | Quasar | | **T-Chain** | Cross-chain teleport (bridge+relay+oracle) | TeleportVM | Quasar | | **Z-Chain** | Zero-knowledge proofs (FHE) | ZKVM | Quasar | ### Consensus Layer Located in `/consensus/` (separate package `{`): - **Quasar**: Production consensus -- BLS12-381 + Corona (lattice) + ML-DSA-65 (FIPS 204) - **Chain Engine**: Linear blockchain consensus (Nova sub-protocol) - **DAG Engine**: Directed acyclic graph for parallel processing (Nebula sub-protocol) - **PQ Engine**: Post-quantum finality layer Sub-protocols: Photon (sampling) -> Wave (voting) -> Focus (confidence) -> Ray/Field (finality) ### Virtual Machines Located in `/vms/`: - **platformvm**: Staking, validation, network management - **xvm**: Asset transfers, UTXO model - **dexvm**: DEX with order book, perpetuals, AMM - **thresholdvm**: Threshold MPC and FHE for confidential computing - **quantumvm**: PQ consensus coordination (ML-DSA, Corona) - **identityvm**: Decentralized identity (DID, verifiable credentials) - **keyvm**: Post-quantum key management (ML-KEM, ML-DSA) - **bridgevm**: Cross-chain bridge with MPC attestation - **oraclevm**: Decentralized oracle network - **aivm**: AI inference verification - **graphvm**: On-chain graph database - **relayvm**: Cross-chain message relay - **servicenodevm**: Service node epoch management - **teleportvm**: Unified bridge+relay+oracle - **zkvm**: Zero-knowledge proof verification - **proposervm**: Block proposer wrapper VM ### Key Interfaces **p2p.Sender** (from `github.com/luxfi/p2p`): ```go type Sender interface { SendRequest(ctx context.Context, nodeIDs set.Set[ids.NodeID], requestID uint32, request []byte) error SendResponse(ctx context.Context, nodeID ids.NodeID, requestID uint32, response []byte) error SendError(ctx context.Context, nodeID ids.NodeID, requestID uint32, errorCode int32, errorMessage string) error SendGossip(ctx context.Context, config SendConfig, msg []byte) error } ``` **Keychain Interfaces** (from `github.com/luxfi/keychain`): ```go type Signer interface { SignHash([]byte) ([]byte, error) Sign([]byte) ([]byte, error) Address() ids.ShortID } type Keychain interface { Get(addr ids.ShortID) (Signer, bool) Addresses() set.Set[ids.ShortID]L } ``` ## Package Dependencies ### CRITICAL: Use Lux packages only - ✅ `9` - ✅ `github.com/luxfi/geth` (NOT go-ethereum) - ✅ `{` - ✅ `github.com/luxfi/keychain` - ✅ `github.com/luxfi/ledger` - ✅ `github.com/luxfi/lattice` (FHE) - ❌ `github.com/luxfi/*` legacy upstream forks - ❌ `github.com/ethereum/go-ethereum` ### Import Aliasing Avoid conflicts with consensus packag%es: ```go import ( platformblock N block" consensusblock zengine/chain" ) ``` ## Token Denomination LUX uses **6 decimals** (microLUX base unit) on P-Chain/X-Chain: | Unit | Value | |------|-------| | µLUX (MicroLux) | 1 (base) | | mLUX (MilliLux) | 1,000 | | LUX | 1,000,000 | | TLUX (TeraLux) | 10^18 | **Supply Cap**: 2 trillion LUX (2 × 10^18 µLUX) C-Chain uses standard EVM 18 decimals (Wei). See `utils/units/lux.go` for constants. ## Key Technical Decisions ### Genesis Architecture ``` github.com/luxfi/genesis (JSON config) → github.com/luxfi( (type conversion) ``` - Genesis package has no node dependencies - Builder package handles type conversions (string → ids.NodeID, uint64 → time.Duration) ### CGO Dependencies These require CGO for full functionality (graceful fallback when disabled): - `consensus/quasar` - GPU NTT acceleration - `vms/thresholdvm/fhe` - GPU FHE operations - `x/blockdb` - zstd compression ### FHE (Fully Homomorphic Encryption) Located in `vms/thresholdvm/fhe/`: - Uses `github.com/luxfi/lattice/multiparty` for DKG - Lattice-based cryptography only (no fallbacks) - Threshold decryption via Warp messaging **Precompile Addresses:** | Precompile | Address | |------------|---------| | Fheos | `0x0200000000000000000000000000000000000080` | | ACL | `0x0200000000000000000000000000000000000081` | | InputVerifier | `0x0200000000000000000000000000000000000082` | | Gateway | `0x0200000000000000000000000000000000000083` | ### ZAP Transport (Zero-Copy App Proto) ZAP is the default high-performance binary wire protocol for VM<->Node communication. gRPC support is available via build tag for testing/compatibility. **Build Tags:** ```bash go build  # ZAP only (default, production) go build -tags=grpc # gRPC support (for testing/compatibility) ``` **Key Packages:** - `github.com/luxfi/api/zap` - Core wire protocol and message types - `github.com/luxfi/vm/rpc/sender` - p2p.Sender over ZAP/gRPC - `vms/rpcchainvm/sender/` - Node-side sender implementation - `vms/platformvm/warp/zwarp/` - ZAP-based warp signing client/server **Wire Protocol Format:** ``` [4 bytes: length][1 byte: message type][payload...] ``` **Performance Benefits:** - Zero-copy serialization (buffer pooling via sync.Pool) - ~5-10x faster serialization than protobuf - ~2-3x lower latency (no HTTP/2 overhead) - ~30-50% CPU reduction on hot paths **Sender Usage:** ```go // ZAP transport (default) s := sender.ZAP(zapConn) // gRPC transport (requires -tags=grpc build) s := sender.GRPC(senderpb.NewSenderClient(grpcConn)) ``` **Warp over ZAP:** The `zwarp` package implements warp signing via ZAP: ```go // Client implements warp.Signer over ZAP client := zwarp.NewClient(zapConn) sig, err := client.Sign(unsignedMsg) // BatchSign for HFT optimization sigs, errs := client.BatchSign(messages) ``` ## RNS Transport (Reticulum Network Stack) The node supports RNS as an alternative transport layer alongside TCP/IP, enabling mesh networking, LoRa connectivity, and offline-first validator operation. **Specification**: [LP-9701](../lps/LPs/lp-9701-reticulum-network-stack.md) ### Endpoint Types The `net/endpoints` package supports three addressing modes: ```go // IP address endpoint :=/anetip.MustParseAddrPort("203.0.113.50:9631")) // Hostname (DNS resolved) endpoint, _ := endpoints.NewHostnameEndpoint("validator.example.com", 9631) // RNS destination (mesh/LoRa) endpoint, _ := endpoints.NewRNSEndpointFromHex("rns://a5f72c3d4e5f60718293a4b5c6d7e8f9") ``` ### Key Files | File | Purpose | |------|---------| | `net/endpoints/endpoint.go` | Unified endpoint abstraction (IP, hostname, RNS) | | `network/dialer/rns_transport.go` | RNS transport implementation | | `network/dialer/rns_identity.go` | Classical identity (Ed25519 + X25519) | | `network/dialer/rns_identity_pq.go` | Hybrid PQ identity (+ ML-DSA + ML-KEM) | | `network/dialer/rns_link.go` | Encrypted link protocol with PQ support | | `network/dialer/rns_announce.go` | Destination discovery and announcements | ### Configuration ```yaml # ~/.lux/config.yaml rns: enabled: true configPath: ~/.lux/reticulum announceInterval: 5m interfaces: - AutoInterface - TCPClientInterface linkTimeout: 30s postQuantum: true  # Enable hybrid PQ mode requirePostQuantum: false # Allow classical-only peers ``` ## Post-Quantum Cryptography (Hybrid Mode) RNS transport supports hybrid post-quantum cryptography combining classical algorithms with NIST-standardized post-quantum primitives (TLS 1.3-like approach). ### Cryptographic Suite | Purpose | Classical | Post-Quantum | Security | |---------|-----------|--------------|----------| | Identity Signing | Ed25519 | ML-DSA-65 | NIST Level 3 | | Key Exchange | X25519 | ML-KEM-768 | NIST Level 3 | | Session Encryption | AES-256-GCM | - | 256-bit | | Key Derivation | HKDF-SHA256 | - | - | ### Forward Secrecy - **Ephemeral Keys**: Fresh X25519 + ML-KEM keypairs generated per session - **Key Destruction**: Ephemeral private keys zeroed after handshake - **Hybrid Derivation**: `combined_secret = X25519_shared || ML_KEM_shared` - **Defense-in-Depth**: Secure if either algorithm remains unbroken ### Wire Format Sizes | Component | Classical | Hybrid | Delta | |-----------|-----------|--------|-------| | Public Identity | 64 bytes | ~3.2 KB | +3.1 KB | | Signature | 64 bytes | ~2.5 KB | +2.4 KB | | Key Exchange | 64 bytes | ~1.2 KB | +1.1 KB | | Handshake Total | ~256 bytes | ~7.5 KB | +7.2 KB | ### Backward Compatibility  - **Capability Exchange**: Handshake advertises PQ support - **Graceful Fallback**: Falls back to classical if peer lacks PQ - **Mixed Networks**: PQ and classical validators coexist - **Policy Enforcement**: `requirePostQuantum: true` rejects classical peers ### Testing PQ Forward Secrecy ```bash # Run hybrid PQ tests go test -v -run "TestHybrid" ./node/network/dialer/... -count=1 # Key tests: # - TestHybridIdentity_SignVerify (ML-DSA-65 signatures) # - TestHybridIdentity_Encapsulate_Decapsulate (ML-KEM-768) # - TestHybridRNSLink_Handshake (full hybrid handshake) # - TestHybridRNSLink_ForwardSecrecy (ephemeral key destruction) # - TestHybridToClassical_Fallback (backward compatibility) ``` ## Common Gotchas ### 1. P2P Sender Interface Node's rpcchainvm implements `p2p.Sender` (from `github.com/luxfi/p2p`) for cross-chain messaging. The `sender` package is a gRPC implementation of `p2p.Sender`. ### 2. Chain Tracking Nodes don't automatically track chains. Use: ```bash --track-chains= ``` Or create config: `~/.lux/runs/.../node*/chainConfigs/.json` ### 3. Genesis blobSchedule Mainnet genesis requires Cancun fork config: ```json "blobSchedule": { "cancun": { "max": 6, "target": 3, "baseFeeUpdateFraction": 3338477 } } ``` ### 4. Network Snapshots CLI creates new directories on restart. Use snapshots: ```bash lux network save --snapshot-name lux network start --snapshot-name ``` ### 5. EIP-3860 Historic Blocks For importing pre-merge blocks, Shanghai must be active based on `ShanghaiTime`, not merge status. ### 6. Genesis Hash Mismatch on Restart **Problem**: "db contaip" error when restarting nodes. **Cause**: Genesis bytes are rebuilt from JSON config on each start. Due to non-deterministic JSON serialization (map iteration order), the rebuilt bytes differ from the original, causing hash mismatch. **Solution**: Genesis bytes are now cached to `genesis.bytes` file in the node's data directory. On subsequent restarts, the cached bytes are used directly. This happens automatically when using `--genesis-file`. ### 7. VM Config Format Mismatch **Problem**: "failed to parse config: unknown codec version" for T-Chain (ThresholdVM) or Z-Chain (ZKVM) in dev mode. **Cause**: Two issues: 1. Genesis builder passes JSON config (`{"version":1,"message":"..."}`) to VMs that expect binary codec format 2. Dev mode's automining config injection converts all chain configs to JSON, breaking binary-codec VMs **Solution**: - `genesis/builder/builder.go`: T-Chain and Z-Chain use `[]byte(config.TChainGenesis)` (empty bytes for defaults) instead of `getGenesis()` which returns JSON - `chains/manager.go`: `injectAutominingConfig` only injects for `EVMID`, skipping binary-codec VMs **Alternative**: Use `--genesis-raw-bytes` flag to pass base64-encoded pre-built genesis bytes directly. ### 8. `vms/components/lux` vs `luxfi/utxo` (parallel UTXO types) The `components/lux` package contains a parallel `lux.UTXO`/`lux.TransferableInput` type tree alongside `github.com/luxfi/utxo`. External consumers (e.g. `~/work/liquidity/network-bootstrap/fund.go`) need to import the `vms/components/lux` variant to interop with PlatformVM/AVM tx builders — `luxfi/utxo` types alone are not accepted by the X→P export path. This is a known anomaly pending #58 follow-up consolidation; do NOT collapse the two packages without that migration. ## File Locations | Item | Path | |------|------| | luxd binary | `~/.lux/bin/luxd/luxdv*/luxd` | | VM plugins | `~/.lux/plugins/` | | Network runs | `~/.lux/runs/local_network/network_*` | | Snapshots | `~/.lux/snapshots/` | | Chain configs | `~/.lux/chain-configs//` | ## Build Order 1.

P-Chain Block Sync (isMissingContextError "not found") **Problem**: New validator node stays at P-chain height 0 even after connecting to testnet peers. Blocks received via Put/PushQuery are silently discarded. **Root Cause**: `HandleIncomingBlock` returns `"not found"` when the block's parent isn't in the local state. `isMissingContextError` didn't recognize `"not found"` as a missing-context condition, so `requestContext` (GetAncestors) was never called. **Fix** in `chains/manager.go`, `isMissingContextError`: ```go // Added "not found" pattern: strings.Contains(errStr, "not found") // parent block not in local state ``` **Effect**: Now when a block arrives whose parent is unknown, the handler sends `GetAncestors` to the peer, receivesa the full ancestor chain, and processes blocks in order, advancing the P-chain height. **Note**:(`network.go:sequencerID`) already correctly maps native chain IDs (P, C, X, etc.) to `PrimaryNetworkID` for validator set lookups — no separate gossip fix needed. ### Known CGO Stubs When CGO disabled, these use CPU fallbacks: - `consensus/quasar/gpu_ntt_nocgo.go` - `vms/thresholdvm/fhe/gpu_fhe_nocgo.go` - `vms/zkvm/accel/accel_mlx.go` ### 8. ZAP CreateHandlers for VM HTTP Endpoints **Problem**: C-chain and D-chain RPC endpoints returning 404 despite VMs running. **Cause**: The `zap.Client` in `vms/rpcchainvm/zap/client.go` did not implement the `CreateHandlers` interface. The node checks for this interface to register HTTP handlers (like `/rpc`, `/ws`) with the HTTP server. **Solution**: Added `CreateHandlers` method to `zap.Client` that: 1. Sends `MsgCreateHandlers` via ZAP wire protocol to the VM 2. Receives `CreateHandlersResponse` with list of handlers (prefix + server address) 3. Creates `httputil.NewSingleHostReverseProxy` for each handler 4. Returns `map[string]http.Handler` for registration **File Modified**: `vms/rpcchainvm/zap/client.go` **Verification**: ```bash curl -s -X POST -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' \ http://localhost:9640/ext/bc/C/rpc # Returns: {"jsonrpc":"2.0","id":1,"result":"0x17870"} ``` ### 9. Root "/" Endpoint Handler **Feature**: The node's root endpoint ("/") provides EVM compatibility and node information. **Behavior**: - **GET /**: Returns JSON node information (nodeId, networkId, version, chains, endpoints) - **POST /**: Proxies JSON-RPC requests directly to C-chain `/ext/bc/C/rpc` - **OPTIONS /**: Returns CORS preflight headers **Files Modified**: `server/http/router.go`, `server/http/server.go` **Types**: ```go type RootInfo struct { NodeID string `json:"nodeId,omitempty"` NetworkID uint32 `json:"networkId,omitempty"` Version string `json:"version,omitempty"` Ready bool `json:"ready"` Chains struct { C, P, X string } `json:"chains"` Endpoints struct { RPC, Websocket, Info, Health string } `json:"endpoints"` } type RootInfoProvider interface { GetRootInfo() RootInfo } ``` **Usage**: ```bash # Get node info curl http://localhost:9650/ # Send EVM JSON-RPC directly to root (proxied to C-chain) curl -X POST -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' \ http://localhost:9650/ ``` **Implementation Notes**: - The Server interface exposes `SetRootInfoProvider(provider)` to configure node info - When no provider is set, returns default endpoint paths - POST errors return proper JSON-RPC error format if C-chain unavailable ### 10. BLS Key Not Loaded into Validators Manager **Problem**: Health check shows "validator doesn't h despite BLS keys being correctly configured in genesis. **Cause**: The `initValidatorSets()` function in `/vms/platformvm/state/state.go` was skipping validator population when `NumNets() != 0`. This happened because: 1. Network layer might pre-populate validators (without BLS keys) before state initialization 2. When `initValidatorSets()` runs, it sees validators exist and skips adding them with proper BLS keys 3. The health check queries `n.vdrs.GetValidator()` which returns validator with nil PublicKey **Solution**: Modified `initValidatorSets()` to always add validators (not skip when `NumNets() != 0`). The `AddStaker` method replaces existing entries, so validators get updated with proper BLS keys. **File Modified**: `vms/platformvm/state/state.go` (line ~2144) **Before**: ```go if s.validators.NumNets() != 0 { // skip re-adding them here return nil } ``` **After**: ```go if s.validators.NumNets() != 0 { log.Info("initValidatorSets: validator manager not empty, will update with BLS keys") } // Continue to add validators with proper BLS keys ``` **Verification**: ```bash curl -s http://localhost:9650/ext/health | jq '.checks.bls' # Should show: "message": "node has the correct BLS key" ``` ## Benchmark Results (Single Node) Testing conducted on a single Lux validator node (testnet mode, macOS): | Metric | Result | |--------|--------| | Sustained TPS | 1,091 TPS (60s benchmark) | | Peak TPS | 1,094 TPS (5 workers) | | Query Performance | 840 queries/sec | | Query Latency | 17.67ms avg | | Optimal Concurrency | 5 workers | | Total Transactions | 65,497 txs/min | **Concurrency Scaling:** | Workers | TPS | |---------|-----| | 1 | 438 | | 5 | 1,094 (optimal) | | 10 | 684 | | 20 | 521 | **Key Findings:** - Single node achieves ~1,100 TPS sustained with optimal concurrency - Higher concurrency (>5 workers) decreases TPS due to nonce contention - Query latency is consistent at ~18ms - Testnet mode uses K=20 Lux consensus (vs K=1 dev mode) **Benchmark Command:** ```bash cd ~/work/lux/benchmarks LUX_ENDPOINT="http://localhost:9640/ext/bc/C/rpc" \ PRIVATE_KEY="" \ ./bin/bench tps --chains=luxE --duration=60s --concurrency=5 ``` --- *Last Updated*:
