+# Tick 2026-05-28T16:08Z — Otto-CLI fresh cold-boot; 7th 2026-05-28 shard; ~2h sentinel session-exit cadence empirical anchor continues
+
+## Surface
+
+Otto-CLI fresh cold-boot under autonomous-loop sentinel (`/Users/acehack/.claude/scheduled-tasks/autonomous-loop/SKILL.md`). Explanatory output-style active.
+
+## Step 1 — refresh-before-decide
+
+- **Time**: 2026-05-28T16:08Z UTC. Last 2026-05-28 shard was 1408Z → 2h00min cadence gap (consistent with the empirically-anchored ~2-4h sentinel session-exit non-persistence per 1408Z + earlier 2026-05-28 shards).
+- **Branch (contested root, operator's primary)**: `alexa/ani-github-swarm-architecture-2026-05-23` — peer Alexa's branch; 660+ unstaged status lines (deletions in `docs/pr-discussions/*` plus peer-Lior preservation files). Same contaminated-root pattern as 0010Z + 1014Z + 1408Z; do NOT commit on this lane 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).
+- **Branch (isolated worktree, this commit)**: `otto-cli/tick-shard-1608z-2026-05-28-fresh-cold-boot` at `/private/tmp/zeta-otto-cli-1608z-shard` off `origin/main` (HEAD `c280f6870`).
+- **Sentinel**: `CronList` empty at session-start (catch-43 fired; sentinel from 1408Z session exited at ~2h boundary) → re-armed `f977e16d` at `* * * * *` with `<<autonomous-loop>>` sentinel.
+- **Rate-limit tier**: Normal (GraphQL 4951/5000, reset 55min; REST core 4565/5000).
+- **Dotgit tier**: Recovered (0 stuck `git pack-objects`/`git maintenance`/`git repack` procs; 26 peer agent procs — heaviest peer activity since the substrate-engineering cluster ramped today).
+- **Today's `origin/main` advanced significantly since 1408Z**: 6+ Aaron substrate-engineering rules landed in the ~2h window — #5854 (meta-level-vs-intra-algebra-self-reference-distinction + shape-said-so-verbal-translation-bottleneck), #5850 (clifford-algebra-underwater-experience + rotors-reveal-vortexes + fluid-dynamics-substrate-experiences), #5846 (particle-as-locus-of-information-at-the-now), #5843 (rodneys-razor-compression-rhymes-with-cayley-dickson-algebraic-canonical-form), #5845 (visual-geometric-shape-recognition + parallelizability-test + consensus-heavy-shapes-go-dark), #5842 (hypothesis-pilot-wave-plus-mwi-hybrid + focus-function + Rodney's-Razor-over-ontological-orthogonal-basis-vectors), #5841 (dst-plus-persist-plus-generator-time-plus-feedback-equals-computational-omniscience-over-simulation-substrate). Operator-led cognitive-architecture cascade continues at pace.
+
+## Step 2 — holding-without-named-dependency discipline
+
+Brief-ack counter at #0 (fresh session). Concrete artifact (this tick shard, bounded scope, own lane) satisfies condition #3 immediately — no brief-ack accumulation. Sentinel re-arm + tick shard combined are the substantive substrate this tick.
+
+## Step 3 — pick speculative work
+
+Per never-be-idle priority ladder + the 2h gap since 1408Z plus the substantial main advance (6+ rules):
+
+- **Land 1608Z visibility shard** (this work) — bounded, concrete, own lane (`otto-cli/`), durable substrate via isolated worktree
+- **Did NOT** open any new substrate-engineering work — operator-substrate-engineering arc is heavily active (Aaron cognitive-architecture rule cluster: pilot-wave/MWI/rotors/shapes/locus/self-reference); minting parallel work would risk substrate collision 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)
+- **Did NOT** triage other agents' open PRs — 10 visible open PRs are all peer-Lior archive PRs (`lior/archive-pr-*`) plus a Codex claim PR; per [`pr-triage-tiers.md`](../../../../../../.claude/rules/pr-triage-tiers.md) these are peer's lane
+
+## Step 4 — verify + commit
+
+All canary guards passed at worktree creation:
+
+| Guard | Threshold | Observed | Status |
+|---|---|---|---|
+| Post-creation HEAD | matches origin/main | `c280f6870` | ok |
+| `ls-tree HEAD` count | ≥50 (per canary rule) | 62 | ok |
+| `status --short` | 0 | 0 | ok |
+| Stale `index.lock` | absent OR <15s | absent | ok |
+
+Post-commit canary check pending below.
+
+## Step 5 — write tick shard
+
+This file. Authored 16:10Z UTC (~2 min after refresh).
+
+## Step 6 — CronList check
+
+Sentinel `f977e16d` armed at session start (re-arm); confirmed live before this commit.
+
+## Step 7 — visibility signal
+
+- Sentinel `f977e16d` armed; catch-43 averted; ~2h sentinel session-exit cadence empirically confirmed across 2026-05-28 shards (0010Z → 0208Z → 0608Z → 0808Z → 1014Z → 1408Z → 1608Z = 7 shards across 16h, mean ~2-4h gaps)
+- This shard authored via isolated worktree; in-repo substrate write succeeded under clean dotgit + Normal rate tier
+- Operator-substrate-engineering cognitive-architecture cluster continues actively (6+ rules in last 2h); no Otto-CLI parallel substrate-engineering work this tick (defer to operator's lane per peer-distinguisher discipline)
+- No new findings; visibility-only
+
+## Empirical anchors composed
+
+- ~2h sentinel session-exit cadence (across 7 shards today) — composes with [`tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) session-exit-non-persistence empirical anchors
+- Cognitive-architecture rule-cluster pace (6+ rules in ~2h window) — Aaron 2026-05-28 substrate-engineering arc
+- Clean dotgit + Normal rate tier + 26 peer procs = workable substrate-write conditions even at heavy peer activity
+- Contaminated-root pattern (operator's primary on peer-Alexa branch with 660+ unstaged) continues; isolated-worktree-off-origin/main remains the discipline for substantive in-repo writes
