Kills pcodecs from 3 complete subsystems (verified go test ./... = 155 ok / 0 FAIL):
- proposervm: block/state/summary struct-is-wire (blockwire.go + statewire.go;
deleted block/state/summary codec.go). blockKind bytes: reserved=0 signed=1
option=2. Epoch inlined in unsigned object. proposer/windower chainSource seed
= binary.LittleEndian (byte-identical to old wrappers.Packer.UnpackLong).
- example/xsvm: tx/block/genesis native Marshal (deleted 3 codec.go); create-chain
example uses genesis.Marshal().
- components: message.Tx native (deleted codec.go); keystore codec shell removed;
index pcodecs.LongLen → local const.
- evm/{predicate,lp176}: off pcodecs.
- platformvm residual: state metadata + genesis + metrics + signer + stakeable
native, vestigial serialize tags removed.
REMAINING (careful solo, agents weekly-capped): warp (reverted — agent left an
ID≠Marshal consensus inconsistency in ChainToL1Conversion; needs proper review,
not a golden-regen) + xvm (reverted — barely started). pcodecs package stays
until those 2 land. /ext/→/v1/ endpoint change also pending.
