+## Holding discipline (step 2)
+
+Named work: my own PR #3165 has BLOCKING failures. Top priority per blocked-green-ci rule.
+
+## Speculative work (step 3) — became recovery work
+
+PR #3165 had 3 distinct issues to address:
+
+### 1. CI: `check docs/BACKLOG.md generated-index drift` FAILED
+
+I'd added a new backlog row (B-0514 at `docs/backlog/P3/`) but hadn't regenerated `docs/BACKLOG.md`. The integrity check at `.github/workflows/backlog-index-integrity.yml` enforces consistency.
+
+Resolution: `BACKLOG_WRITE_FORCE=1 bun tools/backlog/generate-index.ts` (the script refuses overwrites by default; force flag required after the row-file restructure). Added 7 missing entries: B-0460, B-0500-B-0506, B-0514. Verified clean via `--check`.
+
+### 2. CI: `lint (markdownlint)` MD032 FAILED
+
+1825Z shard line 49: list directly followed prose without blank line separator. Fixed by inserting blank line.
+
+### 3. Codex P2 thread: shard count inconsistency
+
+Shard says "6 open PRs" but table listed 7. Fix: removed #3156 from the table (it had merged earlier this session, not part of the refresh count) + added parenthetical note about its lineage for #3161.
+
+## Verify + commit (step 4)
+
+Committed all 3 fixes at `e12106c` (BACKLOG.md regen + shard fix), pushed to PR #3165 branch.
+
+Codex thread `PRRT_kwDOSF9kNM6CJ2vZ` resolved via GraphQL.
+
+**Gate state post-fix**: BLOCKED → wait-ci (4 required in-progress, 0 failed, threads:0, autoMerge armed). New CI will cycle; auto-merge will fire when all required pass.
+
+### Side observation: git index lock
+
+`git -c commit.gpgsign=false commit` returned "Another git process seems to be running" on first attempt. Stale `.git/index.lock` — likely another parallel-Otto worktree finishing a write. The lock file actually didn't exist by the time I checked (`ls -la .git/index.lock` → no such file). Retry succeeded.
+
+Also a new untracked file appeared mid-tick: `docs/research/2026-05-14-deepseek-shadow-wormhole-horizon-controls-spaghettification-aaron-disclosure.md` — another parallel-Otto landing substrate. Not mine; left untouched and not included in this tick's commits.

+- **PR #3165 recovered**: 3 CI fails + 1 thread → 0 fails + 0 threads (autoMerge armed; wait-ci ETA imminent)
+- **Razor-cadence cumulative**: 12/47 rules audited (~26%), 84/85 LIVE (99%); B-0514 captures the 1 MISS finding
+- **Parallel-Otto signals**: stale index lock + new deepseek-shadow-wormhole research file — peer agents are active on `/private/tmp/*` worktrees
+
+## Notes for future-Otto
+
+**BACKLOG.md regen is required after adding a row** — `BACKLOG_WRITE_FORCE=1 bun tools/backlog/generate-index.ts`. The integrity check is mandatory CI. Easy to forget when filing rows in a per-tick context; would benefit from a pre-commit or post-row-file-create hook.
+
+**Markdownlint MD032 hazard**: lists must have blank lines above + below. Easy to miss when writing prose-then-list inline. The rule is well-known but per-tick shard writing skips the visual check.
+
+Mechanization candidate (composes with B-0506): a per-tick or per-file `tools/hygiene/audit-tick-shard-prerequisites.ts` that runs markdownlint + the BACKLOG.md regen check locally before push. Not filed this tick.
