docs/plans/implementation.md records the wave structure (core -> substrate fork || pg engine -> sqlite engine -> contract suite -> release), the decided points (contract-suite layout = option (a), engine-tests vs equivalence-suite split, no CI, mem-engine/fuzzing deferrals surfaced), and the review-gate rhythm. Wave 1 (foundations): workspace scaffold, core errors/validation, value types, trait surface, contract-suite scaffold (+ADR-022), review gate. Wave 2 (substrate fork): fork scaffold/provenance, connection+watcher port, queue-op re-derivation on contract v1, provenance/floor close, review gate.
