External (HTTP / JSON-RPC) is the only place JSON is legitimate. Every
existing encoding/json import in node/ moves to github.com/go-json-experiment/json
(v2 root, not the v1 sub-package). NewEncoder/NewDecoder rewrite to
MarshalWrite/UnmarshalRead. MarshalIndent rewrites to Marshal with
jsontext.WithIndent. json.RawMessage rewrites to jsontext.Value.
*json.SyntaxError rewrites to *jsontext.SyntacticError.
81 files migrated. LLM.md captures the rule + v1->v2 delta table.
Known v2 semantic deltas surfaced by existing tests (followups, not regressions):
- [N]byte fields with no MarshalJSON now marshal as base64 string (v1 marshalled
as JSON array of byte numbers). Affects vms/platformvm/txs/*_test.go fixtures
with embedded BLS proofOfPossession.
- time.Duration has no v2 default representation; configs that wire-format
Duration as nanoseconds (vms/{xvm,platformvm}/config, config/spec) need to
switch to string-form Duration or carry an explicit option. v2 root does not
re-export FormatDurationAsNano.
- v2 enforces strict UTF-8 (vms/chainadapter/messaging fixture has non-UTF-8).
- json.MarshalWrite does not append a trailing '\n' (v1 NewEncoder.Encode did);
service/auth/auth_test.go expectation updated.
- nil []byte round-trips to empty (not nil); config_test deep-equal fixtures
surface this.
All affected sites are at the API boundary; ZAP wire envelope already covers
the internal data paths (state, P2P, consensus, MPC, threshold). Internal
JSON sites that should move to ZAP next (separate work):
- vms/da/store.go (DA blob/cert storage as JSON)
- vms/platformvm/airdrop (airdrop claims as JSON in db)
- vms/chainadapter/appchain (SQLite materializer schema/data blobs)
- vms/chainadapter/messaging (conversation codec)
- staking/kms.go (KMS HTTP client — external technically, leave)
- utils/{bimap,ips} (small marshaler shims — low priority)
