## ✅ Recently shipped (this session)

- **PR-x scrub completed** — 11 staged files committed in `0d7e51e`; second batch (~30 references) followed the same translation rules as the prior `2bbf857`. 90/90 targeted tests green, ruff format clean.
- **WikiMaintainer lifespan wiring** — committed in `2bfe470`. `WikiPageStore` + `WikiMaintainer` are initialised in `src/beever_atlas/server/app.py` after `SyncScheduler.startup()`, then `worker.subscribe_extraction_done(...)` registers a `create_task` callback that fans extraction batches to `maintainer.on_extraction_done(channel_id, fact_ids, mode=settings.wiki_maintenance_mode)`. 130/130 targeted tests green.
- `POST /api/channels/{id}/wiki/maintain` no longer returns `reason=maintainer_not_initialized`; `WIKI_MAINTENANCE_MODE=auto` now actually fires per-batch.

---

## 📋 Remaining work (prioritized)

### 🟡 P1 — Nice to have before staging soak

1. **MCP tool wrappers** (~1 hour)
   - The endpoints exist. The MCP server in `src/beever_atlas/api/mcp_server/` needs three new tool functions:
     - `search_memory(query, scope?)` — cross-channel agent recall via Weaviate hybrid search
     - `lint_wiki(channel_id)` — proxies POST `/wiki/lint`
     - `get_extraction_status(channel_id)` — proxies GET `/extraction-status`
   - Look at existing tools in `_tools_retrieval.py` for the pattern.

2. **Wiki migration script** (~1 hour)
   - Spec task 6.16. One-shot migration from legacy `wiki_cache.pages.{page_id}` subdocs to per-page `wiki_pages` rows.
   - Pattern: copy `src/beever_atlas/scripts/migrate_imported_messages_to_channel_messages.py` and adapt.
   - Idempotent via the compound unique index; supports `--dry-run`.

### 🟢 P2 — Polish / longer-horizon

3. **Integration docs** — `docs/integrations/openclaw.md`, `hermes.md`, `push-sources.md`
   - Spec tasks 5.21-5.23. Cookbook for "register a source + sign a request + handle replays".

4. **Per-channel `wiki_maintenance_mode`** — analyst's recommendation
   - Today it's a global env var. Spec D10 says it should be per-channel.
   - Migration: add `wiki_maintenance_mode` field to the channel document, fall back to env var, expose UI toggle.

5. **Page-voice drift A/B comparator** — spec task 7.19
   - The maintainer has the seam; need the actual comparator that runs both `apply_update` and `WikiBuilder.generate_wiki` in parallel during soak and reports edit-distance.
   - Two-week comparison gates the `WIKI_MAINTENANCE_MODE=auto` default flip.

6. **Re-run the full code review** after the lifespan-wiring commit lands on `main`. Three Opus passes already approved the prior state; this is a smoke check that the scrub + lifespan wiring didn't introduce subtle issues.

## 🎯 Design evaluation — is this redesign actually better?

**Yes, on all four stated outcomes.** Honest assessment:

| Outcome | Before redesign | After |
|---|---|---|
| **Faster pipeline** | Sync blocks on LLM extraction; 100-msg sync = ~5 min | Sync persists messages and returns in ~3 sec; extraction proceeds in background. **~100x faster perceived sync.** |
| **Errors don't kill the pipeline** | Single Gemini 503 → cursor doesn't advance, all batches discarded | Cursor advances on fetch success regardless; failed rows auto-retry with exponential backoff; CircuitBreaker centralizes the fast-fail. **Validated by simulated 503 storm test.** |
| **LLM Wiki bookkeeping** | Full regenerate every refresh; 7+N_clusters LLM calls per refresh | Maintainer routes new facts to affected pages deterministically; rewrites only changed sections; preserves title/slug/voice. **Bounded cost, compounds instead of regenerates.** |
| **Push-ready (OpenClaw / Hermes)** | No push endpoint | `POST /api/sources/{id}/events` with HMAC + 24h idempotency + 10MB streaming body cap. **OpenClaw can integrate today.** |

### Weaknesses honestly:

1. **`WIKI_MAINTENANCE_MODE` is still global, not per-channel.** Operators can't tell channel A "auto" and channel B "manual" without code change. Acknowledged limitation; tracked as P2.4 above.

2. **Failover seam is dead code in OSS.** `_FAILOVER_ENABLED=False` ships disabled because OSS doesn't have a second-provider key (Gemini Flash Lite as fallback for Gemini Pro is same-provider — when the primary's down so is the fallback). Real cross-provider failover needs enterprise tier.

3. **No worker observability.** No metrics endpoint exposing queue depth / claim rate / failure rate. Operator has to grep logs. Worth adding before scale matters.

4. **Pre-existing test pollution** in `tests/test_sync_runner.py` (4 tests fail under certain pytest orderings). Not caused by the redesign; same on `main`. PR-C structurally removed the cause (module globals) but a stale fixture interaction remains.

5. **Frontend is unblocked but raw.** The Tensions / Lint / Maintain / Enriching UI ships, but no component tests for the new pieces (only the dedupeErrors util has unit tests). A polish pass for visual regressions is worth doing on a real channel.

6. **No staging soak metrics dashboard.** The runbook says "watch this Mongo aggregation" but there's no Grafana / metrics endpoint to see them in real time. Operators will use the API endpoint + Mongo shell.

### Things we considered and explicitly DIDN'T do (for good reasons):

- **Multi-tenancy / ACL / SSO / non-chat extractors** — explicitly OUT OF SCOPE per the OSS positioning. Deferred until customer pull.
- **Real durable queue (Redis / BullMQ)** — Mongo queue is sufficient at OSS scale. Architecture supports swapping.
- **Obsidian export / external markdown** — explicitly rejected by user; wiki UI lives in-app.
- **`KnowledgeAtom` rename of `channel_messages`** — Opus consensus rejected as cosmetic churn.
- **Prometheus / Grafana metrics emission** — structured logs + status endpoint cover OSS visibility.

## ✅ What's been verified

- **207/207 backend PR-A→G tests pass** (last full run before context tight)
- **65/65 web tests pass** (last run after frontend additions)
- **`tsc --noEmit` clean** (last check)
- **`ruff check src/ tests/` clean** (last check, before scrub agent's edits — the scrub edits should also pass since it's just comment changes)
- **`ruff format --check src/ tests/` clean** (last check)
- **Three sequential Opus 4.7 code reviews APPROVED** — zero CRITICAL / HIGH / MEDIUM open issues
- **Architect + Analyst Opus reviews on env var cleanup** — converged on the 6-flag surface that shipped

## 🧱 wiki-llm-native-redesign — editorial layer (P0–P3 ship)

The `redesign/oss-pipeline-and-wiki` branch additionally carries the
`wiki-llm-native-redesign` change. The change closes the gap between
"plumbing of an LLM Wiki" (already shipped on this branch) and "the
editorial layer that makes one valuable" — per-page-kind synthesis
prompts, `[[wikilink]]` cross-links, curation (pin / hide / split /
merge), a wiki-graph view, and an MCP read surface.

**Spec:** `openspec/changes/wiki-llm-native-redesign/` (proposal,
design, specs, tasks; gitignored).

**Flag:** `WIKI_LLM_NATIVE_REDESIGN` (default OFF for legacy installs;
flipped ON in fresh-install `.env.example` only after the per-kind
drift soak in `docs/runbooks/wiki-maintenance-soak.md` §22.8 closes).

**Existing-install upgrade path:**

1. Pull the branch — no behaviour change yet (flag is default OFF).
2. Run `uv run python -m scripts.migrate_wiki_pages_to_slug_identity --dry-run`
   to inspect the slug + kind backfill on existing pages.
3. Run the same script without `--dry-run` once the dry-run output
   looks correct. Idempotent — safe to re-run.
4. Set `WIKI_LLM_NATIVE_REDESIGN=true` in `.env`, restart `beever-atlas`.
5. Optionally enable the per-kind drift A/B during a soak window:
   `WIKI_DRIFT_AB=true` + `WIKI_DRIFT_AB_PER_KIND_SAMPLE_RATE=0.05`.
6. Watch `/admin/wiki-drift` (per-kind facets visible after first sync).
7. After 7 clean days per the §22.8 pass criterion, open the PR that
   flips the `.env.example` default.

**What ships behind the flag:**

- Per-page-kind synthesis prompts in `src/beever_atlas/wiki/prompts/`
  (`topic.txt`, `entity.txt`, `decisions.txt`, `faq.txt`,
  `action_items.txt`).
- JSON-Schema validation of each kind's structured payload
  (`src/beever_atlas/wiki/schemas/`).
- `[[wikilink]]` parser + resolver writing `cross_links` (dict) +
  `cross_links_broken` (list) to `wiki_pages`, plus REFERENCES edges
  in Neo4j.
- Curation API: `POST /api/channels/{id}/wiki/pages/{slug}/{pin|hide|split|merge}`.
- Wiki graph route at `/channels/{id}/wiki/graph` (Cytoscape.js,
  lazy-loaded — chunk is split from the wiki tab's main bundle).
- MCP read tools: `read_wiki_page`, `list_wiki_pages`, `get_wiki_graph`.

**What does NOT ship in v1 (documented seams):**

- Agent-write `propose_wiki_edit` MCP tool — the `wiki_proposed_edits`
  Mongo collection is reserved (TTL=30d, indexed by
  `(channel_id, slug, status)`); v2 will register the tool.
- Multi-tenant ACL on individual wiki pages.
- Cross-channel wiki federation.
- Real-time collaborative editing.

**v1 → v2 forward-compat invariants:**

- The `cross_links: dict[str, str]` field is title→slug. Future schema
  changes that flatten this back to a list will need a migration.
- `kind` is an open string, not an enum. Adding new kinds requires a
  new prompt + schema file pair AND a `_KNOWN_KINDS` update.
- `MongoDBStore.startup` adds `wiki_merge_proposals` and
  `wiki_proposed_edits`. Existing installs auto-create on next boot.
