+# Tick 2026-05-16T04:51Z — Otto-CLI
+
+Fifth tick of the resume-session series. PR #3744 (last tick's
+shard) still in CI bounded wait. Rather than emit a brief-ack, did
+substantive substrate work: extended
+[`.claude/rules/backlog-item-start-gate.md`](../../../../../../.claude/rules/backlog-item-start-gate.md)
+with a companion **row-close gate** section codifying the drift /
+partial / multi-slice triage discipline that surfaced during this
+session's drift-catch burst. Hit GitHub GraphQL rate limit
+mid-tick; PR-create succeeded but auto-merge arm + verification
+deferred to next tick.
+
+## Refresh result
+
+| Surface | State |
+|---|---|
+| Cron sentinel | Alive (`bd1c7739`) |
+| Peer Otto-CLI / Desktop | Still detected |
+| `origin/main` | Advanced `cb7c400 → 907c0c2` (likely PR #3744 + peer's PR #3743 merging) |
+| PR #3744 (0444Z shard) | Was OPEN at tick-open; main advancement suggests it may have just merged |
+| PR for `chore/backlog-item-close-gate-otto-cli-2026-05-16` | Created via gh CLI (output cut by rate-limit); PR number unknown to me at write-time; auto-merge arm + verification **deferred** |
+| GraphQL rate limit | **0/5000 remaining**; resets ~04:56Z (~5 min) |
+
+## Speculative work picked + rationale
+
+PR #3744 in real bounded named-dependency wait. Per never-be-idle
+ladder, parallel-track substantive substrate work was the right pick.
+
+The drift-vs-partial-vs-multislice distinction discovered last tick
+needed substrate landing — it was only weather (in chat + a tick
+shard) and would have decayed at session-end without a rule pointer.
+Per [`.claude/rules/wake-time-substrate.md`](../../../../../../.claude/rules/wake-time-substrate.md)
+discipline: load-bearing patterns need wake-time landing.
+
+Extended `backlog-item-start-gate.md` (rather than minting a new
+rule) because the two gates are mirror disciplines at opposite ends
+of a row's lifecycle.
+
+## Landed artifacts
+
+| Artifact | Status |
+|---|---|
+| `.claude/rules/backlog-item-start-gate.md` | +60 lines: row-close gate section with 3-class triage table + 30-second triage procedure + naive-sweep warning |
+| Commit | `559f7cd` on `chore/backlog-item-close-gate-otto-cli-2026-05-16` |
+| Pushed | Yes (branch tracks origin) |
+| PR | Created via `gh pr create` — exit message confirmed (URL line cut by rate-limit) |
+| Auto-merge arm | **Deferred** — `gh pr merge --auto` returned `rate limit already exceeded` |
+| This shard | `docs/hygiene-history/ticks/2026/05/16/0451Z.md` |
+
+## Rate limit handling per `refresh-world-model-poll-pr-gate.md`
+
+The rule's cost-awareness section explicitly anticipates this:
+
+> `poll-pr-gate-batch.ts --all-open` fires ~N `gh pr view` calls
+> (N = open PR count, ~37 in cascade-mode). At 4× polls per cascade
+> hour + cross-tick `gh` operations + multi-agent shared-token
+> consumption (Otto-CLI + Otto-Desktop + Lior + Vera + Riven all
+> draw from Aaron's user-token), the 5000 GraphQL/hour budget
+> exhausts.
+
+This session has been exactly that shape: 5 ticks each making ~3-5 `gh` calls, alongside Lior's continuous PR-archive work and peer Otto-Desktop's parallel PR-creates. Total: budget exhausted at ~5003/5000.
+
+**Recovery discipline this tick applied:**
+
+- Stop further `gh` calls until reset (~5 min)
+- Continue with non-gh work (git operations + file edits)
+- Defer auto-merge arm + verification to next tick
+- Document the deferral in this shard for next-tick continuity
+
+## Composes with substrate
+
+- This tick's rule-extension PR (chore/backlog-item-close-gate-otto-cli-2026-05-16)
+- PRs #3733 + #3737 + #3742 (the three drift catches that motivated the rule)
+- Peer Otto-Desktop's PR #3743 (B-0528 close — fourth drift catch in parallel)

+## Real-dependency-waits active
+
+- PR #3744 (0444Z shard) — auto-merge armed last tick; may have merged during this tick (main advanced `cb7c400 → 907c0c2`)
+- Rule-extension PR — open, auto-merge **not yet armed**; will arm in next tick when rate limit resets (~04:56Z)
+- This shard's PR — to be created next tick (after rate-limit reset)
+
+## Visibility signal
+
+- Rule extension landed as commit `559f7cd`; PR opened; auto-merge arm deferred to next tick due to rate limit
+- GitHub GraphQL rate limit exhausted (0/5000); resets ~04:56Z
+- Next tick: re-poll rate limit; if green, arm auto-merge on rule-extension PR + create PR for this shard
+- Sentinel `bd1c7739` alive
+
+Stopping foreground; cron will fire the next tick.
