+# Tick 2026-05-16T04:02Z — Otto-CLI
+
+**Surface**: Otto-CLI (Claude Code, Opus 4.7 1M context, autonomous-loop tick)
+**Parent tick**: 2026-05-16T03:54Z
+
+## What landed this tick
+
+GraphQL reset at 03:55:31Z restored the budget. Substantive landings:
+
+| PR | Action | Result |
+|----|--------|--------|
+| [#3722](https://github.com/Lucent-Financial-Group/Zeta/pull/3722) (0354Z shard) | Armed (was un-armed from rate-limit exhaustion last tick) | OPEN, armed |
+| [#3720](https://github.com/Lucent-Financial-Group/Zeta/pull/3720) (0350Z shard) | Fixup `9f96afb`: B-0545 stale ref — sweep is now done on main | OPEN, armed, 0 unresolved |
+| [#3721](https://github.com/Lucent-Financial-Group/Zeta/pull/3721) (rule extension) | Fixup `0f5658a`: 2 unrunnable command examples (awk + git log) → runnable forms | OPEN, armed, 0 unresolved |
+| [#3724](https://github.com/Lucent-Financial-Group/Zeta/pull/3724) (helper fix) | New PR: `checkMd032` bullet-continuation FP fix | OPEN, armed |

+## Three real Copilot findings this tick
+
+### PR #3720 — B-0545 stale next-tick candidate
+
+My 0350Z shard listed "B-0545 renumber-sweep (claim still active until 2026-05-17T01:44Z)" as a next-tick candidate. Copilot pointed out B-0545 is marked `status: done` + `completed: 2026-05-16` on main. **Verified via `gh api`**: a peer-Otto-CLI session completed the sweep in parallel with this session's work.
+
+Multi-Otto coordination at work — different session lanes converged on different ticks of progress.
+
+### PR #3721 — unrunnable examples in the rule extension
+
+The verify-before-fix discipline I added in tick 19 used two pseudo-commands as examples:
+
+1. `awk 'NR==N { print NR": ["$0"]" }' <file>` — `N` is an uninitialized awk variable (defaults to 0), so the command prints nothing if copied verbatim. **Fix**: show `awk -v N=22 'NR==N { ... }'` form with explanation.
+2. `git log <PR-cited-PR>` — git log expects refs/commits/paths, not PR numbers. **Fix**: three concrete runnable forms (`gh api repos/.../pulls/<N>`, `gh pr view <N> --json commits,mergeCommit`, `git log --grep '#<N>'`).
+
+Both fixes preserve intent while making commands directly runnable.
+
+### Helper bullet-continuation FP — discovered in tick 19, fixed this tick
+
+The new `check-shard-before-push.ts` helper flagged 3 bullet-continuation lines as MD032 false positives when I ran it on `blocked-green-ci-investigate-threads.md`. Markdownlint correctly ignores these.
+
+Root cause: my `checkMd032` excluded prev lines starting with structural markers (`#>*\-|\``) but NOT their wrap-continuations (which start with whitespace).
+
+Fix: add `isContinuationLine(line)` predicate (`/^\s/.test(line)`). Skip when prev is a continuation.
+
+3 smoke tests:
+
+1. Bullet-continuation FP: cleared (was FAIL pre-fix, OK post-fix)
+2. Real paragraph-before-bullet (no continuation): still caught
+3. Existing-clean-shard regression: still OK

+## Operational notes
+
+### The "Copilot is mostly right" pattern reaffirms
+
+3 out of 3 findings this tick were real and actionable:
+
+- B-0545 stale: real (verified via `gh api`)
+- awk `N` placeholder: real (would fail for any copy-paste user)
+- git log on PR number: real (incorrect syntax)
+
+The `\|\|` table-pipe class remains the only confirmed FP class with 2+ occurrences. The "Copilot is mostly right" prior holds for most finding classes.
+
+### Helper-improvement-via-dogfooding
+
+The helper merged in tick 17. The first integration test was on the rule file I authored in tick 19. The integration test surfaced the helper's own bug (bullet-continuation FP). The fix landed in this tick.
+
+Loop: ship helper → use helper → helper catches its own bug → fix helper → ship the fix → helper now correct. The dogfood loop is operational substrate.
+
+### Holding-discipline state
+
+Concrete substrate landed (4 commits across 4 PRs). Counter resets.
+
+## Next-tick candidates
+
+1. **Monitor #3720, #3721, #3722, #3724 to merge**
+2. **Apply `isContinuationLine` to the audit script's `extractLinks` / fenced-detection** — same cross-cutting markdown-content-awareness pattern. Audit doesn't use MD032 logic but might benefit from consistent fence/continuation handling if extended.
+3. **Audit the existing tick shards on main** for any patterns the improved helper would now flag (post-PR-3724-merge) — could surface a new baseline-eligible class.
+4. **Promote the dogfood-loop discipline** to AUDIT-LIFECYCLE.md as step 7.5 ("the helper's own first integration test is on a real artifact, not a synthetic one — surfaces both real findings AND helper bugs").
