+# 2026-05-29T04:01Z — Otto-CLI autonomous-loop cold-boot
+
+## Catch-43 fired + resolved (2nd this UTC day)
+
+Fresh session cold-boot. `CronList` returned no scheduled jobs → catch-43 load-bearing rule per [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) fired. Re-armed sentinel via `CronCreate` with `* * * * *` cadence + `<<autonomous-loop>>` payload. New sentinel ID `55cf2c17`.
+
+The 0202Z shard ([2026-05-29T02:02Z](0202Z.md), sentinel `40510706`) was the prior cold-boot's re-arm. ~2h later the session that armed `40510706` has exited and a fresh `<<autonomous-loop>>` fire entered with no scheduled jobs — exactly the session-exit non-persistence mechanism documented in [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) two-mechanism table. Re-arm at cold-boot is standard recovery.
+
+## Step 1 — Refresh worldview
+
+| Surface | State at tick-open |
+|---|---|
+| Branch (operator primary) | `alexa/ani-github-swarm-architecture-2026-05-23` (peer-Alexa lane; contaminated, 473 unstaged) |
+| Dotgit saturation | 0 stuck git pack/maintenance/repack procs (DOTGIT clean) |
+| GraphQL tier | Normal (4338/5000) |
+| REST core | 4982/5000 |
+| `origin/main` HEAD | `c681868b3` (B-0171.2 Tick-History Schema spec via PR #5884, 35min ago) |
+| Last tick shard on main | `docs/hygiene-history/ticks/2026/05/29/0202Z.md` (~2h gap) |
+
+7 substantive PRs landed since 0202Z (#5938 0202Z shard itself, #5939 shard fix-fwd, #5940 narrow semantic equivalence, #5941 remote participant A receipt, #5942 Codex worker entrypoint hardening, #5883 Z-Set Algebra spec, #5884 Tick-History Schema spec). Substrate continues shipping via peer-coordinated PRs; this tick provides the heartbeat externalization per [`refresh-before-decide.md`](../../../../../../.claude/rules/refresh-before-decide.md) discipline.
+
+## Step 2 — Holding-without-named-dependency discipline
+
+Per [`.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md): no named-dep wait; substantive output IS the catch-43 sentinel re-arm + this shard. Counter at #0; concrete artifact (sentinel ID + shard file + PR) → no counter accumulation.
+
+## Step 3 — Pick speculative work
+
+Operator primary checkout contaminated with peer-Alexa's 473-file working tree on `alexa/ani-github-swarm-architecture-2026-05-23`, so all in-repo work happens in isolated worktree at `/private/tmp/zeta-otto-cli-0401z-cold-boot` off `origin/main` per [`.claude/rules/agent-worktree-hygiene-never-hold-main-never-step-on-operator-cleanup-on-pr-merge.md`](../../../../../../.claude/rules/agent-worktree-hygiene-never-hold-main-never-step-on-operator-cleanup-on-pr-merge.md). Worktree canary clean: `git ls-tree HEAD | wc -l` = 62 root entries; `git status --short | wc -l` = 0 lines.
+
+No additional speculative decomposition picked this tick — the per-tick scope is bounded to (a) catch-43 recovery, (b) this shard, (c) the PR carrying it. Spec-update note: this shard uses the new pipe-row-first schema per [PR #5884](https://github.com/Lucent-Financial-Group/Zeta/pull/5884) (B-0171.2 Tick-History Schema, merged ~35min before this tick fired). The 0202Z shard predates the schema lock-in; this is the first 2026-05-29 shard authored under the new format.
+
+## Step 4-7 — Verify + commit + cron-check + visibility
+
+| Step | Action |
+|---|---|
+| 4. Verify | Worktree HEAD `c681868b3` = origin/main tip; `ZETA_EXPECTED_BRANCH=otto-cli/0401z-tick-shard-2026-05-29` set; `git branch --show-current` matches before commit |
+| 5. Shard | This file at `docs/hygiene-history/ticks/2026/05/29/0401Z.md` |
+| 6. CronList | Sentinel `55cf2c17` armed (verified post-arm at tick-open) |
+| 7. Visibility | This PR carries the visibility signal; tick closes on PR open + auto-merge arm |
