+# Tick 1808Z — Cold-boot, catch-43 re-arm, 12h-gap continues cold-boot-cascade pattern
+
+## Step 1 — Refresh
+
+- `git fetch origin main` clean; `git ls-tree HEAD = 61` baseline matches
+- Recent merges since 0608Z (12-hour window):
+  - `2774fef5a` fix(ci P0): cascade #4 audit bootloader any-of (#5125)
+  - `df3591dc2` rule: dep-pin-search-first + fighting-past-self-recurrence (#5126)
+  - `1f75e8420` backlog(B-0720): decompose classifier-bypass safety lane (#5124)
+  - `c1fd188fb` backlog(iter-6): 6-row cluster-update substrate (#5123)
+  - `ed6a7b8b9` fix(postmerge-5121): 2 Copilot findings (#5122)
+  - `ac2e0c39c` fix(B-0823): suffix-pattern match nixpkgs 25.11 store-hashed paths (#5263)
+  - `7ffdb5ff8` feat(B-0824): generator-as-time-source + IObservable simulation (#5265)

+  - `20a4596ba` feat(B-0824): post-#5241 enrichments — generators-not-data (#5257)
+  - `8a80f9511` docs(shadow): Otto/Riven paralysis lesson (#5255)
+
+Substrate trajectory: 10+ PRs landed in the 12h window — B-0823 nixpkgs fix-forward,
+B-0824 generator/time-source substrate, safety-lane decomposition, cluster-update
+iter-6 cascade, rule landings (dep-pin-search-first per `dep-pin-search-first-authority.md`,
+fighting-past-self recurrence). Active substrate engineering throughout window.
+
+## Step 2 — Holding discipline
+
+Brief-ack #1 with **named bounded wait**: PR #5269
+([`lior/preserve-5263`](https://github.com/Lucent-Financial-Group/Zeta/pull/5269))
+opened minutes before this tick — `BLOCKED`, CodeQL CI in progress (csharp/go/java-kotlin
+analyzers all `IN_PROGRESS` at 18:07:38Z; auto-merge armed). This is a `lior/...` branch
+(peer Lior surface lane per `agent-roster-reference-card.md`). Per
+`fighting-past-self-vs-peer-agent-distinguisher-...md`: peer's lane → coordinate, do not
+touch. Discriminator pass:
+
+| Discriminator | Result | Classification |
+|---|---|---|
+| Branch prefix `lior/...` | Peer Lior surface | PEER (not mine) |
+| PR author | Lior (need to verify but branch prefix is canonical) | PEER |
+| Substrate scope | Preservation of substrate around #5263 | PEER work |
+
+→ Abstain from PR #5269 in-flight. Operator+peer will close the loop.
+
+## Step 3 — Pick speculative work
+
+Substrate-honest visibility-shard. Considered + abstained:
+
+- Mass worktree triage (20+ Otto-CLI worktrees in `/private/tmp/zeta-*` per
+  `agent-worktree-hygiene-...md` Rule 4) — high-value but unbounded; deserves its own
+  scoped tick, not a brief-ack-#1-after-12h-gap tick
+- Cleaning up the 2 untracked files in operator primary (`tools/alignment/out/filter-gate-log.jsonl`
+  + `xcrun_db`) — those are operator-scope, not my lane
+- Substrate authoring on B-0824 generator/time-source cascade — peer Otto-CLI/Riven
+  threads are actively iterating; coordinate-not-touch applies per the rule
+
+Visibility-shard captures the 12h-gap observation + the cold-boot-cascade pattern
+recurrence anchor (per user-scope memory `feedback_cold_boot_cascade_continues_independent_of_dotgit_clearance_5th_today_dotgit_recovered_named_dep_pr_4937_wait_ci_otto_cli_2026_05_25.md`).
+
+## Step 4 — Verify + commit
+
+Verify-before-defer composition (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)):
+
+- `git worktree add /private/tmp/zeta-otto-cli-tick-1808z-2026-05-26 -b otto-cli/tick-1808z-... origin/main`
+  → exit 0, "HEAD is now at ac2e0c39c", 100% (6741/6741) files extracted
+- Post-creation guard: `rev-parse HEAD = ac2e0c39c8...`, `status --short` empty (0 lines),
+  `ls-tree HEAD = 61` (matches origin/main baseline)
+- 9th empirical anchor for verify-before-defer composition working under
+  dotgit-NOT-saturated + 6 peer-Lior-procs conditions (the discriminator remains
+  raw stuck-git-proc-count, not raw peer-proc-count)
+
+## Step 5 — This shard
+
+`docs/hygiene-history/ticks/2026/05/26/1808Z.md` (this file)
+
+## Step 6 — Cron check
+
+`CronList` returned empty at session start → catch-43 fired → `CronCreate` armed
+`<<autonomous-loop>>` with cron `* * * * *` → job ID `76fdab6a`. Per
+`tick-must-never-stop.md` session-exit non-persistence mechanism: prior session's
+sentinel died with its process; ~12h-gap is consistent with multiple session-exit
+events in the window (not a 12h-continuous-saturation event — dotgit clean here).
+
+## Step 7 — Visibility signal
+
+Cold-boot complete. Sentinel re-armed (`76fdab6a`). Named bounded wait: PR #5269
+peer Lior preserve-5263 CI in progress (~5-10 min ETA). No substantive in-repo work
+this tick. Brief-ack #1 valid per
+[`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md)
+N=6 counter (1-2 brief-acks acceptable with named bounded wait).
+
+12h gap since 0608Z + this fresh cold-boot empirically anchors continuing
+cold-boot-cascade pattern (now spanning 2026-05-25 + 2026-05-26): independent of
+dotgit-saturation state, sentinel session-exit-non-persistence drives ~2h-cycle
+cold-boots. The pattern is **not** a saturation indicator; it's the harness's
+own session lifecycle.
