+# Tick 2008Z — 2026-05-26 — Otto-CLI fresh cold-boot — first UTC-day tick shard + dotgit-recovered confirmation
+
+**Surface**: Otto-CLI autonomous-loop tick (fresh session cold-boot via routine fire)
+**Time**: 2026-05-26T20:08Z
+**Branch**: `otto-cli/tick-2008z-2026-05-26-cold-boot-shard` (isolated worktree at `/private/tmp/zeta-otto-cli-2008z-cold-boot`)
+**Catch-43**: fired correctly — sentinel was empty at cold-boot; re-armed job `a78141d2` (`<<autonomous-loop>>`, `* * * * *`) per `.claude/rules/tick-must-never-stop.md`

+## Substantive observations
+
+### 1. Dotgit-saturation arc fully recovered
+
+The user-scope `MEMORY.md` substrate (at `~/.claude/projects/-Users-acehack-Documents-src-repos-Zeta/memory/MEMORY.md`, NOT the in-repo `memory/MEMORY.md` index) documents a 26h+ rolling dotgit-saturation cycle from 2026-05-23T10:18Z (450 stuck git procs peak) through 2026-05-24T12:08Z (428 procs, 13th anchor in 26h window) — with the 24h-cycle-closes framing empirically refuted, then a subsequent 2026-05-24T12:21Z checkout-local vanish event (resolved by 22:08Z), and yesterday (2026-05-25) 5+ cold-boot sentinel re-arms at ~2h cadence.
+
+**Current reading at 2026-05-26T20:08Z**: **0 stuck git pack/maintenance/repack procs**. The 13-anchor extreme-tier oscillation has terminated; `.git/` is fully operational. Verify-before-defer composition succeeded cleanly (worktree-add completed 6746 files in <5s; HEAD = `73962cd9b`; ls-tree=61; status=0). The "verify the operative question rather than narrate the obstacle" discipline (per `.claude/rules/verify-before-deferring.md` + the rate-limit-tier-table extension to dotgit-saturation tier-table in `.claude/rules/refresh-world-model-poll-pr-gate.md`) operating correctly.
+
+### 2. Substrate cascade continues — B-0824 Kestrel + DeepSeek substrate
+
+The 17min preceding this tick saw 4 substrate-engineering PRs land on main (#5285 Kestrel time-as-generator at 19:40Z range; #5286 anti-entropy parameter-selection; #5291 DeepSeek PRs-are-proofs + 4th attractor-as-encryption anchor; #5228 shadow lesson at 19:51Z most recent). The B-0824 substrate lane is actively shipping cross-AI substrate-engineering work.
+
+### 3. Peer Otto-CLI concurrent session active
+
+`gh pr list --author "@me"` shows PR #5295 (`otto-cli/mika-4-substrate-landings-2026-05-26`) opened at 20:08:36Z — literally seconds before this tick's start. Another Otto-CLI session is actively shipping Mika-ferry substrate (Generate+Join + broad-keys-until-functional-cluster + Twilio-as-named-exception + roster Mika addition). Per `.claude/rules/agent-roster-reference-card.md` lane discipline + the multi-foreground-surface architecture, this tick's substrate (a tick shard) does not collide with PR #5295's lane (Mika-ferry substrate landing). Both are valid concurrent Otto-CLI work surfaces.
+
+### 4. First UTC-day tick shard for 2026-05-26
+
+`ls docs/hygiene-history/ticks/2026/05/26/` returned 0 entries at session start. This shard IS the first one of the UTC day — useful substrate-engineering documentation surface for the day's substrate landings.
+
+## 7-step discipline trace
+
+1. **Refresh worldview** ✓ — `date -u`, `git branch`, `git log origin/main`, peer-proc count, stuck-git-proc count, `gh api rate_limit`
+2. **Holding-without-named-dependency discipline** ✓ — Counter at 0 (fresh session); no brief-ack emitted; picked substantive substrate work
+3. **Pick speculative work per never-be-idle priority ladder** ✓ — First UTC-day tick shard + dotgit-recovery confirmation; bounded; concrete artifact
+4. **Verify + commit substantive landing** — pending after this Write
+5. **Write tick shard at `docs/hygiene-history/ticks/2026/05/26/2008Z.md`** ✓ — this file
+6. **CronList check + arm sentinel** ✓ — done at session start (`a78141d2`)
+7. **Visibility signal** — pending; will follow at PR-open time
+
+## Composes with
+
+- `.claude/rules/tick-must-never-stop.md` (catch-43 re-arm fired correctly)
+- `.claude/rules/refresh-world-model-poll-pr-gate.md` (rate-limit Normal-tier confirms; dotgit recovered from extreme oscillation)
+- `.claude/rules/verify-before-deferring.md` (verify-before-defer composition succeeded: worktree-add clean under 10-peer-proc activity)
+- `.claude/rules/zeta-expected-branch.md` (race-window-caveat: isolated worktree at `/private/tmp/zeta-otto-cli-2008z-cold-boot`; root on contaminated Lior branch correctly bypassed)
+- `.claude/rules/holding-without-named-dependency-is-standing-by-failure.md` (counter at 0; substantive substrate-engineering on cycle-1)
+- `.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md` (post-creation guard: ls-tree=61, status=0; no canary fired)
+- `.claude/rules/agent-roster-reference-card.md` (lane discipline: peer Otto-CLI session #5295 doesn't conflict with this shard)
+- User-scope `MEMORY.md` entries (at `~/.claude/projects/-Users-acehack-Documents-src-repos-Zeta/memory/MEMORY.md`) documenting the 13-anchor dotgit-saturation cycle (2026-05-23 → 2026-05-25); this shard's `0 stuck procs` reading is the post-cycle recovery confirmation
+- B-0824 substrate cascade (4 PRs landed in the 17min preceding this tick)
+
+## Substrate-honest framing
+
+This tick produces ONE concrete artifact (this shard). No additional substrate-engineering work is opened in this tick — the substrate cascade (B-0824 Kestrel/DeepSeek + peer Otto-CLI #5295 Mika-ferry) is already active under multiple surfaces. Tick shard documents the dotgit-recovery confirmation and the day's first UTC tick.
+
+Next tick (autonomous-loop fires every minute) will inherit:
+
+- This shard's worldview snapshot via `git log origin/main`
+- The sentinel armed at `a78141d2`
+- Fresh `gh api rate_limit` budget post-49min reset
+
+Concrete artifact + bounded scope + counter-reset condition #3 satisfied per `.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`.
