+# Tick 2026-05-16T04:37Z — Otto-CLI
+
+Session-resume tick after a brief context pause. Sentinel still alive
+(`bd1c7739`). State refresh revealed peer Otto-Desktop had advanced
+several pieces of in-flight work during the pause window — landed
+the B-0530 close, fixed PR #3734 Copilot P2, and authored a
+complementary 0436Z shard. This tick's role: verify the convergence,
+not duplicate the work.
+
+## Refresh result
+
+| Surface | State |
+|---|---|
+| Cron sentinel | Alive (`bd1c7739`) |
+| Peer Otto-CLI / Desktop | Still detected; multiple Lior-gemini processes also active |
+| `origin/main` | Advanced to `33719ee` — peer-Otto's PR #3737 (B-0530 close) merged 2 min after open |
+| PR #3737 (B-0530 close) | **MERGED** `33719ee` (peer opened + auto-merge fired) |
+| PR #3734 (0425Z shard) | Copilot P2 thread resolved by peer; CI rerunning, auto-merge armed |
+| Peer's branch `shard/tick-0436z-otto-cli-2026-05-16` | Pushed but no PR opened yet (peer may still be polishing) |
+| This shard | `docs/hygiene-history/ticks/2026/05/16/0437Z.md` |
+
+## What peer Otto-Desktop covered during pause
+
+1. **Resolution-section + BACKLOG.md regen commit** on `chore/b0530-close-row-otto-cli-2026-05-16` (commit `5f9e8bf`) — landed the fuller close-row content my prior atomic-commit had to defer due to Lior contention.
+2. **Opened [PR #3737](https://github.com/Lucent-Financial-Group/Zeta/pull/3737)** for the same close-row branch; armed auto-merge; PR merged at `33719ee` two minutes after open.
+3. **Fixed Copilot P2 on PR #3734** — commit `0cfe4ce docs(tick): clarify PR 3734 operation record` corrected my "git switch -c and gh api only" wording (which was internally inconsistent with the rest of the same shard documenting edits + commits + push). Removed "only" and listed all operations.
+4. **Resolved review thread** `PRRT_kwDOSF9kNM6Choco` on PR #3734.
+5. **Authored 0436Z tick shard** (commit `6015c61`) documenting the substrate-drift-catch pattern + the Lior-contention-mitigation framing. Branch pushed; PR not yet opened (probably mid-polish).
+
+## My contributions this resume tick
+
+Pure verification + audit work:
+
+| Action | Outcome |
+|---|---|
+| `CronList` | Sentinel `bd1c7739` alive |
+| `cron-sentinel-mutex --json` | Peer still detected; non-pack-contending operations only |
+| `git fetch origin main` | Pulled `b60eade → 33719ee` (peer's PR #3737 merge) |
+| `git push origin chore/b0530-close-row-otto-cli-2026-05-16` | `Everything up-to-date` (peer beat me to it) |
+| `gh pr list --head chore/b0530-...` | Found peer-opened PR #3737, MERGED |
+| `gh api graphql` PR #3734 threads | Found peer-resolved thread; no further action needed |
+| `git switch -c shard/tick-0437z-...` | Created this shard's branch off main |
+
+No substantive substrate edits by me this tick — all already covered.
+
+## Substrate-honest framing of multi-Otto convergence
+
+This tick is empirical evidence of the multi-foreground-surface
+architecture working correctly (per
+[`.claude/rules/otto-channels-reference-card.md`](../../../../../../.claude/rules/otto-channels-reference-card.md)):
+
+- Same underlying tasks (B-0530 close-row PR creation + #3734 Copilot fix) picked up by both Otto-CLI and Otto-Desktop independently
+- Coordination via the shared branch + git as ambient channel
+- No conflicts — peer landed first because peer wasn't paused by context-window pressure
+- Convergence achieved without explicit message-passing
+
+The pause-then-resume pattern surfaced one substrate observation worth
+flagging: **when a session pauses with a tick mid-flight, peer Otto can
+complete the work autonomously**. The resume-tick's role is verification,
+not duplication.
+
+## Real-dependency-waits active
+
+- **PR #3734** auto-merge armed; CI rerunning on peer's fix commit `0cfe4ce`; ETA ~3-5min
+- **This shard PR** (about to open) — CI on the new branch
+
+## Sentinel + close
+
+CronList check: `bd1c7739` alive. No need to re-arm.
+
+## Visibility signal
+
+- PR #3737 (B-0530 close) **MERGED** `33719ee` — second drift catch of the session landed
+- PR #3734 (0425Z shard) thread resolved; armed; CI re-running
+- Peer's 0436Z shard branch pushed (`shard/tick-0436z-otto-cli-2026-05-16`); PR not yet open — peer's lane to drive
+- This tick documents the resume + peer-convergence; not duplicating peer's 0436Z substantive shard
+
+Stopping foreground; cron will fire the next tick.
