chore: OpenClaw capture handler (llm_output) + ledger sync

- openclaw-plugins/atocore-capture/handler.js: simplified version
  using before_agent_start + llm_output hooks (survives gateway
  restarts). The production copy lives on T420 at
  /tmp/atocore-openclaw-capture-plugin/openclaw-plugins/atocore-capture/
- DEV-LEDGER: updated orientation (live_sha b687e7f, capture clients)
  and session log for 2026-04-16

 ## Session Log
 
+- **2026-04-16 Claude** Ops session: deployed `b687e7f` (project inference from cwd) to Dalidou. Fixed cron logging — was silently failing because `/var/log/` not writable by papa; redirected to `~/atocore-logs/`. Fixed OpenClaw gateway crash-loop (discord `replyToMode: "any"` invalid → changed to `"all"`). Created and deployed `atocore-capture` hook on T420 OpenClaw (`hooks/atocore-capture/handler.js`) using `message:received` + `message:sent` events — gateway running stable with 4 hooks loaded. Backfilled project tags on 179/181 unscoped interactions via docker exec (165 atocore, 8 p06, 6 p04). Validated: Claude Code capture working (50+ interactions), OpenClaw hook installed and awaiting first live interaction for end-to-end confirmation. No code changes to main (hook lives on T420 only). Zero `client=openclaw` interactions exist yet — the hook is new, needs a real user turn through Discord/channels.

 - **2026-04-15 Claude (pm)** Closed the last harness failure honestly. **p06-tailscale fixed: 18/18 PASS.** Root-caused: not a retrieval bug — the p06 `ARCHITECTURE.md` Overview chunk legitimately mentions "the GigaBIT M1 telescope mirror" because the Polisher Suite is built *for* that mirror. All four retrieved sources for the tailscale prompt were genuinely p06/shared paths; zero actual p04 chunks leaked. The fixture's `expect_absent: GigaBIT` was catching semantic overlap, not retrieval bleed. Narrowed it to `expect_absent: "[Source: p04-gigabit/"` — a source-path check that tests the real invariant (no p04 source chunks in p06 context). Other p06 fixtures still use the word-blacklist form; they pass today because their more-specific prompts don't pull the ARCHITECTURE.md Overview, so I left them alone rather than churn fixtures that aren't failing. Did NOT change retrieval/ranking — no code change, fixture-only fix. Tests unchanged at 299.
 
 - **2026-04-15 Claude** Deploy + doc debt sweep. Deployed `c2e7064` to Dalidou (build_time 2026-04-15T15:08:51Z, build_sha matches, /health ok) so R11/R12 are now live, not just on main. **R11 verified on live**: `POST /admin/extract-batch {"mode":"llm"}` against http://127.0.0.1:8100 returns HTTP 503 with the operator-facing "claude CLI not on PATH, run host-side script or use mode=rule" message — exactly the post-fix contract. **R13 closed (fixed)**: added a reproduction recipe to Quick Commands (`pip install -r requirements-dev.txt && pytest --collect-only -q && pytest -q`) and re-cited `test_count: 299` against a fresh local collection on 2026-04-15, so the claim is now auditable from any clean checkout — Codex's audit worktree just needs `pip install -r requirements-dev.txt`. **R10 closed (fixed)**: rewrote the `docs/master-plan-status.md` OpenClaw section to explicitly disclaim "primary integration" and report the current narrow surface: 14 client request shapes against ~44 server routes, predominantly read + `/project/state` + `/ingest/sources`, with memory/interactions/admin/entities/triage/extraction writes correctly out of scope. Open findings now: none blocking. Next natural move: the last harness failure `p06-tailscale` (chunk bleed).
