…nce, and validation baseline Wave 1 — Compaction prompt improvement: - Add three wording-reuse bullets to buildCompactionPrompt() under CRITICAL MEMORY RULES: do not create rephrased duplicates, reuse existing wording exactly when re-emitting, only emit new memories when the fact is new, materially corrected, or more specific. - This attacks the root cause of zero reinforcement: compaction generating variant text for the same durable fact. Wave 2 — Bug fixes: - Bug #2: Add placeholder comment to superseded_existing branch in decision dedupe (unreachable until v1.5.4 numbered refs). Preserve as const type assertions. - Bug #3: Add memory_migration_superseded evidence event type. Both P0 and quality cleanup migrations now produce evidence events for superseded entries. loadWorkspaceMemory appends migration evidence on first-load migrations only (idempotent via migration IDs). No historical backfill. - Bug #4: Add documentation comment explaining that feedback identity key returns exact key (absorbed_identity currently impossible for feedback). Add test verifying this behavior. Wave 3 — Validation baseline script: - Add scripts/dev/validate-identity-keys.ts: read-only script that scans workspace memory stores, computes exact/identity key collisions, and reports reinforcement statistics. Baseline matches audit: 0 exact collisions, 0 identity collisions, 0 reinforcement events across 123 active memories. Identity extension is gated on measurement: if the prompt change produces measurable reinforcement (reinforcementCount > 0), identity extension may be unnecessary. Decision dedupe stays exact-only (Wave 4 deferred).
