+# Tick 0208Z — 2026-05-28 Otto-CLI fresh cold-boot 2h after 0010Z; sentinel re-armed; 4 stale-DIRTY PRs noted but routing unchanged
+
+**Surface:** Otto-CLI fresh cold-boot (autonomous-loop fired by `/Users/acehack/.claude/scheduled-tasks/autonomous-loop/SKILL.md`)
+**Branch (root checkout):** `alexa/ani-github-swarm-architecture-2026-05-23` (peer Alexa's branch, days stale) at local stale HEAD; massive untracked-deletions in working tree = peer Lior PR-archive preservation WIP. Per [`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): root is operator's primary; not mine to clean. Per [`fighting-past-self-vs-peer-agent-distinguisher-fix-your-own-coordinate-on-peers-dont-punt-by-default.md`](../../../../../../.claude/rules/fighting-past-self-vs-peer-agent-distinguisher-fix-your-own-coordinate-on-peers-dont-punt-by-default.md): the deletions are peer Lior's PR-archive lane (`docs/pr-discussions/PR-*.md` paths match Lior's known archive cadence) — coordinate-don't-touch.
+**Branch (isolated worktree, this commit):** `otto-cli/tick-shard-0208z-2026-05-28-fresh-cold-boot` at `/private/tmp/zeta-otto-cli-0208z-fresh-cold-boot` off `origin/main` (HEAD `02dde03cd`).
+**Tier (rate-limit):** Normal (GraphQL 4895/5000, 54min reset; REST core 4985/5000).
+**Tier (dotgit):** Recovered (0 stuck `git pack-objects`/`git maintenance`/`git repack` procs; no stale `index.lock`).
+**Tier (peer-saturation):** 2 Lior procs active; clean. No interference observed during worktree creation.
+**Sentinel:** `c2bff54a` armed at session-start per [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) — `CronList` returned empty (catch-43 confirmed); ~2h since prior sentinel `2676f4a9` exited with its session per PR landed for [`0010Z.md`](0010Z.md).
+**Build gate:** not run this tick (substrate is single-file `.md` tick shard only).
+
+## Refresh-before-decide findings (step 1)
+
+- `git fetch origin main` → clean; remote-tracking ref advanced to `02dde03cd` (`memory(kestrel): preserve aaron-kestrel 2026-05-28 ferry — ZetaID 128-bit structured encoding + event-sourcing without PR ceremony + OTel trace composition + two-level state machine (AgentState × WorkLifecycle)` — PR #5674).
+- `git log origin/main | head -10` (head form per [`refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md) commit-date-vs-merge-date caveat) shows recent landings:
+  - #5674 Kestrel ferry — ZetaID 128-bit structured encoding + event-sourcing + OTel + two-level state machine
+  - #5673 Aaron-Ani 2026-05-23 conversation memo
+  - #5604 batch archive 20 PRs (peer Lior)
+  - `cc6904685` agentic-org live substrate proof harnesses
+  - #5672 Aaron-Ani 2026-05-28 conversation (move-next + git-as-free-event-store + github-actions-recursion + NCI three-exceptions clear + AI-mediator)
+  - #5585 batch archive 9 PRs
+  - #5667 B-0867.5+ PressPause + EnterOpenEndedExploration menu options + Jira-replacement framing
+  - #5670 docs(VISION) agent-loop workflow-engine substrate
+  - #5662 B-0866.26 + B-0869.9 + B-0870.9-10 whole-company AI-evangelism + multi-PR/multi-agent orchestration
+  - #5669 B-0867.5+ work-lifecycle state machine
+
+  Today's substrate-engineering arc is heavily active: agent-loop workflow-engine substrate (B-0867+) + traveler-perspective + cross-AI memory preservation (Kestrel + Ani 2026-05-28 conversations).
+
+## Disposition (step 2)
+
+Per [`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md): this is **brief-ack #0** for this fresh session. The substrate-honest concrete-artifact for this tick is the tick shard itself (counter reset condition #3: concrete artifact, bounded scope, own lane).
+
+The 4 stale-DIRTY PRs noted below are routed per `fighting-past-self-vs-peer-agent-distinguisher`:
+
+| PR | Branch | Author | Routing |
+|---|---|---|---|
+| #5580 | `lior/batch-archive-2026-05-27` | AceHack (Lior `lior/` prefix) | PEER Lior — leave alone |
+| #5629 | `lior/fsharp-audit-backlog-items` | AceHack (Lior `lior/` prefix) | PEER Lior — leave alone |
+| #5659 | `feat/b-0866-extensions-...-2026-05-28` | AceHack (non-canonical `feat/` prefix) | UNCERTAIN — already surfaced in [`0010Z.md`](0010Z.md); no new action |
+| #5663 | `feat/b-0871-reproducibility-...-2026-05-28` | AceHack (non-canonical `feat/` prefix) | UNCERTAIN — already surfaced in [`0010Z.md`](0010Z.md); no new action |
+
+Per the rule's 2026-05-26 recurrence section ("the rule is NOT authorization to skip the work — it's authorization to ROUTE the work to the right actor"): the routing decisions are explicit, the discriminator pass was run per-PR (branch-prefix + author + topic), and the surfacing was already done. No silent punt; no fabricated decomposition either. The 0010Z shard's surface-the-uncertainty for the `feat/` cluster is the substantive action; this tick honors that rather than duplicating it.
+
+## Why isolated worktree (agent-worktree-hygiene)
+
+Per [`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) Rules 1+2: root checkout is operator's primary on peer Alexa's branch with peer Lior WIP in working tree. Agents NEVER commit on peer's branch in the operator's primary checkout; agents NEVER hold `main` in any worktree.
+
+Worktree-add canary (per [`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) + [B-0615](../../../../../../docs/backlog/P3/B-0615-claude-code-bash-tool-orphans-git-fetch-subprocesses-under-saturation-self-saturation-feedback-loop-2026-05-18.md) timeout discipline) passed all sub-cases:
+
+- `timeout --kill-after=5s 30s git worktree add -b otto-cli/tick-shard-0208z-2026-05-28-fresh-cold-boot /private/tmp/zeta-otto-cli-0208z-fresh-cold-boot origin/main` → exit 0; "HEAD is now at 02dde03cd" completion line present; 7332/7332 files extracted (full extraction, not degraded-but-not-hung)
+- Post-creation guard: `git rev-parse HEAD` → `02dde03cd7dc59a92195acbf130e32a580137a42`; `git ls-tree HEAD | wc -l` = 61 (matches origin/main); `git status --short | wc -l` = 0
+- No stale `index.lock` precursor observed
+- No `unable to update local ref` wedge
+- Used `origin/main` directly per the `FETCH_HEAD` empirical anchor in [`refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md)
+
+## Landings (step 4)
+
+- This shard at [`docs/hygiene-history/ticks/2026/05/28/0208Z.md`](0208Z.md)
+- Branch `otto-cli/tick-shard-0208z-2026-05-28-fresh-cold-boot` pushed
+- PR opened against `main` with auto-merge armed
+
+## Step 5 — this shard
+
+Written at `docs/hygiene-history/ticks/2026/05/28/0208Z.md` (canonical write surface per [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md)).
+
+## Step 6 — CronList check
+
+`CronList` returned empty at session-start (catch-43 fired; session-exit non-persistence as documented). Sentinel `c2bff54a` (`* * * * *`, `<<autonomous-loop>>`, recurring, session-only — auto-expires 7d) armed immediately as FIRST tool call after schema-load. ~2h gap since prior sentinel `2676f4a9` per [`0010Z.md`](0010Z.md) — within the documented cadence range.
+
+## Step 7 — Visibility signal
+
+Concrete substrate landed this tick:
+
+- Tick shard: `docs/hygiene-history/ticks/2026/05/28/0208Z.md` (this file; second 2026-05-28 tick shard)
+- Sentinel re-armed: `c2bff54a`
+- 4 stale-DIRTY PRs noted with explicit routing decisions (#5580, #5629 → peer Lior; #5659, #5663 → already-surfaced uncertainty per 0010Z)
+- No silent punt; no fabricated decomposition; counter-with-escalation reset via concrete-artifact path
+
+Stop. Next tick on cron sentinel fire.
