Forget-Me control was initially scoped out as “memory theatrics”
What
Phase 3 Sub-PR 3.3 shipped the persistent-memory layer (KV-backed 14-day session thread, PII redaction, Haiku-generated session recap). The accompanying report explicitly chose NOT to ship a visible memory-clear control, classifying it as one of the “memory theatrics” the Phase 3 brief had warned against.
Why
The Phase 3 brief used the phrase “memory theatrics” to mean ambient UI that announces a fake memory persona (welcome-back banners, profile cards, personality framing). A user-facing privacy control is the opposite of that — it is the trust mechanism that makes operator-grade memory acceptable in the first place. Conflating the two collapsed two separate concerns into one rejection.
Fix
Same-day hotfix added the Eraser-icon Forget-Me button to the chat window header, plus the `/api/chat/forget` endpoint and `forgetSession` helper in `lib/lumina/memory.ts`. The button deletes both the `lumina:session:<id>` and `lumina:summary:<id>` KV buckets server-side and clears every client-side trace synchronously. No confirmation dialog, no localStorage write for the toggle state — operator-grade quiet.
