+# 2026-05-29T02:02Z — Otto-CLI autonomous-loop cold-boot
+
+## Catch-43 fired + resolved
+
+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 `40510706`.
+
+Session-exit non-persistence is the more common cause of sentinel-missing
+at fresh cold-boot than within-session auto-expire — the prior session that
+armed a sentinel exited cleanly + the in-memory cron died with the process,
+exactly per the rule's documented two-mechanism table. Re-arm at cold-boot
+is the standard recovery; no further action needed.
+
+## Step 1 — Refresh worldview
+
+| Surface | State at tick-open |
+|---|---|
+| Branch (operator primary) | `alexa/ani-github-swarm-architecture-2026-05-23` (peer-Alexa lane; contaminated working tree, 473 unstaged) |
+| Dotgit saturation | 0 stuck git pack/maintenance/repack procs (DOTGIT clean) |
+| GraphQL tier | Normal (4130/5000; reset ~4 min) |
+| REST core | 4935/5000 |
+| Peer Lior procs | 0 |
+| `origin/main` HEAD | `d11187aaf` (B-0058.4 alignment clause drift detector, 33min ago) |
+| Last tick shard on main | `docs/hygiene-history/ticks/2026/05/28/2002Z.md` (4h gap) |
+
+10 recent peer-Aaron + peer-Otto PRs landed since the 2002Z shard, including
+B-0058.4 alignment drift detector (#5871), B-0170.1 semantic equivalence
+claim checker (#5881), B-0668 decomposition (#5838), local scope conflict
+broadcast (#5937), PrReviewLifecycle PoC (#5836), and others. Substrate is
+shipping via named-PR landings, not via per-tick shards — the autonomous-
+loop is providing the heartbeat externalization while substantive work
+ships through peer-coordinated PRs.
+
+## 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; this tick's substantive output IS the catch-43 sentinel
+re-arm + this shard documenting the cold-boot. Counter starts at #0; the
+substantive substrate is concrete (sentinel ID + shard file) → no counter
+accumulation.
+
+## Step 3 — Pick speculative work
+
+Cold-boot's substantive output IS the sentinel re-arm + shard. Operator's
+primary checkout is contaminated with peer-Alexa's 473-file working tree
+(branch `alexa/ani-github-swarm-architecture-2026-05-23`), so all in-repo
+work happens in isolated worktree at `/private/tmp/zeta-otto-cli-0202z-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).
+
+No additional speculative decomposition picked this tick — the per-tick
+shard cadence has been ~2h intervals on 2026-05-28 (0010Z → 0208Z → 0608Z →
+0808Z → 1014Z → 1408Z → 1608Z → 2002Z), and the 4h gap suggests the
+sentinel session-exit happened ~1h after 2002Z. The substantive work
+landed via named PRs during the gap (the multi-PR cluster above).
+
+## Step 4 — Verify + commit
+
+Worktree freshness verified: HEAD=`d11187aaf` matches `origin/main`;
+`git ls-tree HEAD` = 62; `git status --short` = 0. No corruption canary
+fired per [`.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md`](../../../../../.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md).
+
+## Step 5 — Tick shard
+
+This file.
+
+## Step 6 — CronList check
+
+Sentinel `40510706` armed per the cold-boot re-arm above.
+
+## Step 7 — Visibility signal
+
+- Sentinel `40510706` armed (catch-43 resolved)
+- Shard `docs/hygiene-history/ticks/2026/05/29/0202Z.md` authored from
+  isolated worktree
+- Branch `otto-cli/tick-2026-05-29-0202z-cold-boot` off `origin/main d11187aaf`
+- No operator-checkout contamination (operator's primary is on Alexa's
+  branch; isolated worktree at `/private/tmp/zeta-otto-cli-0202z-cold-boot`)
+
+Stop.
