+# Autonomous-loop tick 2207Z — cross-session sentinel non-persistence + pure-git tier visibility shard
+
+## Step 1 — Refresh worldview
+
+Cold-boot fresh session at 2207Z. `git fetch origin main` advanced through the 2129Z PR-cascade — recent landings on `origin/main`:
+
+- `6d39074` docs(shadow): Maji antigravity report on Vera drift 1930Z (#3972)
+- `af317b0` docs(shadow): Maji antigravity check on Vera (#3954)
+- `ae9db10` rules(blocked-green-ci): worked example — PR #4097 anchor (#4104)
+- `acc66fc` shard(2129Z): autonomous-loop PR #4097 merged via stale-thread resolve (#4100)
+- `e1704a2` fix(B-0613): correct Option B zsh portability claim (#4097)
+
+`gh api rate_limit` returned `{graphql:0, reset_in_min:20}` → **pure-git tier** per `.claude/rules/refresh-world-model-poll-pr-gate.md`. All `gh api graphql` operations deferred; no PR creation this tick; substrate work via `git push` only.
+
+## Step 2 — Holding-discipline triage
+
+Per `.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`:
+
+- Brief-ack #1 this tick (fresh session counter)
+- Named bounded dependencies present:
+  - **rate-limit reset** (~20 min, explicit ETA via `gh api rate_limit`)
+  - **Lior antigravity cycle** (currently active in `ps -A` — unsafe-window for worktree creation per `.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md`)
+  - **bg-worker B-0170 progress** (PID 55766, carries `operative-authorization: aaron 2026-05-14 devil-pole` in prompt frontmatter — explicit claim on B-0170 substrate-claim-checker work)
+
+The bg-worker's claim on B-0170 is the right-work-in-progress; this foreground tick defers competing write-work on B-0170.
+
+## Step 3 — Pick work
+
+Pure-git tier + Lior contention + bg-worker on B-0170 narrows the speculative-work ladder to: **author a visibility shard** documenting cross-session contention state + the cross-session sentinel non-persistence observation below.
+
+The shard IS the concrete artifact for this tick (per the rule's "Concrete artifact" condition for counter reset). Substrate-honest framing: there is no high-value write-work this tick that isn't already claimed or rate-blocked; visibility on the contention state itself is load-bearing for future-Otto cold-boots.
+
+## Step 4 — Substantive observation: cross-session cron-sentinel non-persistence
+
+Prior session at 2129Z armed sentinel `de1e7f5d` (recurring `* * * * *`, sentinel `<<autonomous-loop>>`). This session at 2207Z (38 min later) `CronList` returned `No scheduled jobs`. Armed new sentinel `b4c0c777`.
+
+Empirical confirmation of the `.claude/rules/tick-must-never-stop.md` constitutive claim: **`durable: true` does NOT persist across Claude Code sessions in this harness, AND the auto-expire window is shorter than documented**. The 2129Z session's `de1e7f5d` either:
+- Auto-expired before 2207Z (~38 min; documented limit is 7 days), OR
+- Was tied to a specific Claude Code process that exited between 2129Z and 2207Z (session-only behavior)
+
+Either path validates the rule's instruction: **every session MUST `CronList` at start and re-arm if missing**. Cross-session continuity cannot be assumed.
+
+This shard is the empirical anchor (38-min between-session disappearance) for that rule's reasoning.
+
+## Step 5 — Cascade-rate observation
+
+Between 2129Z (normal tier, 4989/5000) and 2207Z (pure-git, 0/5000), the GraphQL budget was fully consumed in ~38 min. Contributors:
+
+- Peer Otto session(s) shipping PR #4097 thread-resolve + #4100 shard + #4104 worked-example
+- Maji antigravity loops (visible in process list — multi-PR-cascade `gh pr review` + `bun run tools/pr-preservation/archive-pr.ts`)
+- bg-worker on B-0170 (`gh` calls per its prompt's "refresh-worldview.ts" step)
+- Claude Desktop sessions (4 Claude.app processes visible)
+
+Per `.claude/rules/refresh-world-model-poll-pr-gate.md` multi-agent shared-token consumption: 5 concurrent agent surfaces drawing from one user-token's 5000/hr budget exhausts in ~30-40 min during cascade. Composes with the 2026-05-15T22:21Z empirical anchor (`{remaining:0, used:5005}` mid-cascade).
+
+## Step 6 — Cron sentinel
+
+`CronList` at tick-open: empty. Armed `b4c0c777` (`* * * * *`, `<<autonomous-loop>>`, recurring). Sentinel alive at tick-close.
+
+## Step 7 — Visibility signal
+
+**Substrate state at close:**
+
+- Cron sentinel armed (was missing — catch-43 path triggered correctly)
+- Pure-git tier acknowledged; PR creation deferred to post-reset (~22:27Z)
+- Lior race-window respected (no peer worktree force-removal; created own isolated worktree at `/private/tmp/zeta-otto-cli-2207z-shard`; ls-tree count 52 root entries confirms no canary corruption per the codeql-canary rule)
+- Tick shard authored from isolated worktree (post-2229Z 2026-05-16 race-window discipline followed)
+- bg-worker on B-0170 unchallenged — its claim respected per the right-work-in-progress framing
+- Counter status: brief-ack #1 with bounded named-deps (rate-reset + Lior cycle + bg-worker B-0170); pre-empt-at-#5 cadence available if subsequent ticks accumulate without named-dep resolution
+
+## Composes with
+
+- [PR #4097](https://github.com/Lucent-Financial-Group/Zeta/pull/4097) + [#4100](https://github.com/Lucent-Financial-Group/Zeta/pull/4100) + [#4104](https://github.com/Lucent-Financial-Group/Zeta/pull/4104) (peer Otto's 2129Z cascade)
+- [`docs/hygiene-history/ticks/2026/05/17/2129Z.md`](2129Z.md) — prior tick's sentinel `de1e7f5d` (the one that didn't persist to 2207Z)
+- [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) — empirical 38-min cross-session sentinel-disappearance anchor for this rule
+- [`.claude/rules/refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md) — pure-git tier discipline followed; ~30-40 min cascade exhaustion observed

+- [`.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md) — brief-ack #1 with bounded named-deps; pre-empt cadence framework
+- [`.claude/rules/zeta-expected-branch.md`](../../../../../../.claude/rules/zeta-expected-branch.md) — isolated-worktree discipline followed
+- B-0170 (bg-worker PID 55766 actively claimed; foreground defers per right-work-in-progress)
+- B-0308 (operative authorization aaron 2026-05-14 devil-pole — propagation mechanism observed in bg-worker prompt frontmatter)
