# V2-P8B Kickoff (Continuity Surface Purification)

Status: Active

## Objective
Eliminate ambiguity in continuity read/write authority so runtime continuity injection is deterministic and all non-authoritative continuity artifacts are explicitly demoted.

## Step plan (5)
1. Surface authority contract hardening ✅
2. Derived artifact demotion + metadata normalization ✅
3. Read-path purification sweep ✅
4. Regression and invariants ✅
5. Full sweep + P8B closeout ✅

## Step 5 completion notes
- Completed Step 5 regression sweep and closeout validation.
- Added closeout artifact:
  - `docs/v2_p8b_closeout_checklist.md`
- Sweep result: 15 passed / 0 failed for P8B + adjacent continuity/trigger contract coverage.
- P8B is now closed.

## Step 4 completion notes
- Expanded continuity authority regression coverage in `tests/test_continuity_injection_authority.py`.
- Added invariants for edge/fallback states:
  - record store corrupt + meta present -> meta fallback authority
  - record store empty + meta present -> meta fallback authority
  - no continuity surfaces -> `authority=none`
- Retained authoritative-path assertions for record-store-first behavior.

## Step 1 completion notes
- Added canonical continuity authority contract alignment across docs and runtime loader language.
- Established explicit continuity authority order:
  1) `rolling-window.records.json` (authoritative)
  2) `promoted-context.meta.json` (fallback metadata only)
  3) empty
- Clarified that `promoted-context.md` is derived/operator-facing and never runtime authority.

## Step 2 completion notes
- Normalized continuity metadata semantics across authority and derived surfaces.
- `rolling-window.records.json` now explicitly tags:
  - `authority=rolling_record_store`
  - `role=runtime_continuity_authority`
- `promoted-context.meta.json` now explicitly tags derived fallback role:
  - `authority=promoted_context_meta_fallback`
  - `role=derived_fallback_metadata`
- `promoted-context.md` remains derived/operator-facing only.
- Updated OpenClaw integration guidance to state continuity authority/fallback split.

## Step 3 completion notes
- Completed source sweep for continuity surface path literals across `core_memory/*`.
- Confirmed runtime continuity surface file access is centralized to canonical modules only:
  - `core_memory.continuity_injection`
  - `core_memory.rolling_record_store`
  - `core_memory.rolling_surface`
- Added regression guard:
  - `tests/test_p8b_read_path_purification.py`
  - Fails if non-canonical modules directly reference continuity surface artifacts.
