derives_from: "odd/ledger/2026-04-20-p1-3-3-challenge-canon-parity-landed.md, odd/ledger/2026-04-20-p1-3-2-gate-canary-landed.md, canon/principles/cache-fetches-and-parses.md, canon/principles/vodka-architecture.md, canon/constraints/release-validation-gate.md, canon/principles/contract-governs-handoff-drift.md"
governs: "Fresh-session continuation after P1.3.3 shipped oddkit 0.21.1. Points the next session at P1.3.4 — encode's canon-parity refactor: migrate the trigger-word matcher from regex alternation to stemmed set intersection (D5, same matcher shape as challenge + gate), and remove the module-level cachedEncodingTypes cache per D9 and cache-fetches-and-parses. Encode's trigger vocabulary is already governance-driven (read from odd/encoding-types/*.md at runtime); what remains is the matcher inside the classifier and the in-process cache on the parse products. This is the LAST regex matcher in the sweep. Ship as 0.22.0."

superseded_note: "Shipped as 0.23.0 (not 0.22.0 as originally recommended) after parallel envelope-conformance work claimed 0.22.0 on main during validator dispatch — forward-bumped per release-validation-gate Rule 3. Implementation shipped phrase-subset match (stemmedPhrases: string[][]) rather than flat set intersection (stemmedTokens: Set<string>) after Bugbot caught multi-word-vocab flattening on the first-cut. See closeout ledger for the full fix-forward narrative, both Sonnet 4.6 validator sessions (feat sesn_011CaF5vqjgzN7Mw8s84qvK9 + promotion sesn_011CaF9tx18Af3z1Fy9trwz8, both PASS), and the canon-parity sweep closure marker."
