# Memory Strata WS1–WS10 Final Closure Bundle — 2026-05-25

Status: **closed as documentation / audit / fixture baseline line; push-review gated**  
Scope: WS1 through WS10, including intermediate WS/M milestones  
Topology impact: **unchanged** — no runtime default, Gateway, cron, model routing, release tag, or external write was changed by this closure bundle.

## 1. What is now canonical

The memory-strata line now has a documented boundary model and receipts for all ten workstreams:

- Store / durable memory remains the durable truth owner.
- Episodic memory remains event/session evidence, with payload opt-in and redaction verified on fixture.
- Episodic semantic search is a bounded evidence-retrieval lane, not durable recall and not truth promotion.
- Working Set / Backbone is derived activation context, not a truth owner.
- Graph/topology is a stale-aware derived relationship cache, not a truth owner.
- Pack / Proactive Pack is final context assembly; lifecycle writeback is a real durable mutation and is governed/off by default.
- Promotion/writeback is prohibited by default unless a governed entrypoint, review receipt, and rollback path exist.
- Non-stop controller local surface is installed/readback-verified for this line.

## 3. Milestone review gates

Independent review receipts were captured under `/root/.openclaw/workspace/.state/`:

- M1 review: `.state/claude-memory-strata-m2-review-20260525.md` / initial M2 gate found WS8 stop-loss issue.
- M2 re-review: `.state/claude-memory-strata-m2-rereview-20260525.md` — passed after stop-loss fix.
- M3 review: `.state/claude-memory-strata-m3-review-20260525.md` — passed with carry-forward verifier debt.
- M4 review: `.state/claude-memory-strata-m4-review-20260525.md` — passed for WS7.
- Late-stage review: `.state/claude-memory-strata-late-review-20260525.md` — passed for final closure bundle start.

## 4. Important corrected incident

WS8 counterfactual ran `--pack-lifecycle-write on` against the production OpenClaw memory DB and mutated `observations.detail_json.lifecycle` for two rows. This was rolled back and receipted.

Receipts:

- `docs/receipts/memory-strata-ws8-stop-loss-wal-2026-05-25.md`
- `docs/receipts/artifacts/memory-strata-ws8-lifecycle-write-rollback-2026-05-25.json`
- `docs/receipts/artifacts/memory-strata-ws8-rollback-verification-2026-05-25.json`

Rule carried forward: any durable-touching counterfactual must use a fixture/copy DB or explicit mutation window with pre-snapshot and rollback.

## 5. Carry-forward items

These are **not hidden blockers**; they are intentionally outside this closure scope and must be named before future implementation/default changes.

1. WS6 actual slimming moves still owed; current WS6 is pre-audit only.
2. WS9 five-candidate dry-run fixture still owed: 2 accepted, 2 rejected, 1 deferred.
3. WS9 concrete governed CLI/entrypoints must be enumerated before implementation.
4. Review packet schema and promotion/writeback receipt shape need reconciliation.
5. Pre-mutation snapshot policy needs a concrete artifact path/format.
6. WS5 executable verifier still owed: Working Set injection/dedupe/stale fixture.
7. WS2 full receipt-field coverage still owed: repeat suppression / pinned Working Set / backbone duplicate exclusion.
8. WS4 10 real episodic evidence queries still owed before quality promotion.
9. WS7 fixture rebuild counterfactual still owed before graph participates in defaults.
10. WS10 runner/expected-evidence fixture expansion still owed before runtime/default changes.
11. Apply-gate remains future-only: no write-enabled promotion governor is active.

## 6. Push / tag gate

This bundle does **not** push or tag. Push/tag require explicit CK approval after final review.

## 7. Closure verdict

The WS1–WS10 line is complete as a verifier-backed documentation/audit/fixture baseline. It is not a runtime default promotion, not a live graph refresh, not a bootstrap-slimming apply, and not a write-enabled promotion governor.
