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superseded entries.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).
