# Tick 1202Z — Cold-boot; GitHub Actions outage confirmed; PR #5135 CI not firing

## Step 1 — Refresh

- `git fetch origin main` clean; `git ls-tree origin/main = 61` (root entries baseline)
- HEAD on `main` `cd98323cd` (PR #5134 refresh-before-decide-extends rule landed 10:17Z)
- Recent merges (newest first): #5134, #5037, #5127, #5133, #5110, #5131, #5132, #5130, #5129, #5128 — full cascade between 08:22Z and 10:17Z covering iter-7 (B-0806) Ace-positioning correction, B-0807-0810 renumber, B-0811 re-land, verify-existing-substrate rule, refresh-extends rule
- GitHub state: GraphQL 4955/5000 (Normal), REST core 4987/5000, reset 55min
- Process state: 2 stuck git pack/maintenance/repack (mild); 2 Lior gemini procs; 64 claude procs
- Working-tree on operator primary checkout `main`; isolated worktree spawned at `/private/tmp/zeta-otto-cli-1202z-cold-boot` (HEAD=cd98323cd, ls-tree=61, status=0 — canary clean)

## Step 2 — Holding discipline + Step 3 — Substantive pick

**Named dependency identified**: GitHub Actions outage in progress since
2026-05-26T10:57:14Z per [IncidentHub status checker](https://incidenthub.cloud/status/github/actions).

Empirical evidence from local query (verified before WebSearch confirmation):

- **Last `pull_request`-event workflow run**: `2026-05-26T10:17:14Z` (gate + CodeQL + pr-archive-on-merge all on PR #5134's branch `otto-cli/refresh-extends-working-tree-reads-1008z-2026-05-26`)
- **Last main-merge**: `2026-05-26T10:17:09Z` (commit `cd98323cd`)
- **Workflows since 10:37Z**: 3 only — Automatic Dependency Submission NuGet (10:37Z, dynamic event), CodeQL scheduled (10:36Z), manifesto-citation-snapshot-cadence scheduled (10:36Z, failure)
- **Silence window**: 10:37Z → 12:02Z = **85 minutes of no pull_request workflows**
- **PR #5135 (mine, opened 11:19Z, docs-only 3 files)**: `gh pr checks 5135` returns `no checks reported on the 'otto-cli/...' branch`; `gh api .../check-runs` returns `total: 0`; `gh run list --branch <pr-branch>` returns empty. Commit-canary check: `git ls-tree origin/main = 61` = `git ls-tree PR-HEAD = 61` (commit tree intact; NOT a corruption case per [`.claude/rules/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))

**This is NOT a Zeta-side bug**. The cause is GitHub Actions infrastructure. PR #5135 will fire CI when the outage resolves; until then, no Zeta substrate action will unblock it.

## Step 4 — Substantive pick: empirical-anchor capture

The 85-minute pull_request-workflow silence + the 10:57Z incident start give a clean
empirical anchor for the **CI-degradation-affecting-merge-queue** scenario:

- **Auto-merge armed + 0 checks = stuck at BLOCKED indefinitely until CI fires once**: PR #5135 demonstrates this state. Per `.claude/rules/blocked-green-ci-investigate-threads.md` the BLOCKED-with-green-CI rule's preconditions are inverted here (green-CI isn't possible when CI hasn't fired at all). The investigation discipline still applies but resolves to "wait for CI to come back."
- **Per `.claude/rules/dependency-status-surface.md`**: `docs/dependency-status.md` is the surface that should answer "is GitHub Actions degraded right now?" in 30 seconds. This tick's anchor reinforces the value of that surface.
- **Per `.claude/rules/refresh-world-model-poll-pr-gate.md`**: `bun tools/github/poll-pr-gate.ts 5135` correctly reports `gate: "BLOCKED"`, `nextAction: "none"`. Tooling is operating correctly; the bottleneck is upstream.

## Step 5 — Tick shard

This file IS the shard. Concrete artifact per the
[`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md)
counter-reset condition #3 (bounded scope; explicit named-dep wait stated;
substantive empirical observation captured).

## Step 6 — CronList + sentinel

- CronList at session-start: **empty** (session-exit non-persistence per [`tick-must-never-stop.md`](../../../../../.claude/rules/tick-must-never-stop.md))
- Re-armed: `66463931` cron `* * * * *` sentinel `<<autonomous-loop>>`
- Catch-43 fired correctly per the session-start hook

## Step 7 — Visibility signal

**What landed**:

- Sentinel `66463931` re-armed (catch-43 recovery)
- This tick shard at `docs/hygiene-history/ticks/2026/05/26/1202Z.md` — empirical anchor for GitHub Actions outage 2026-05-26T10:57Z + the 85-minute silence-window observation + PR #5135 stuck-pending state
- Branch `otto-cli/cold-boot-1202z-github-actions-outage-2026-05-26` (isolated worktree, detached-base off origin/main per agent-worktree-hygiene rule)

**Deferred** (CI-outage-dependent):

- Auto-merge arming for the tick-shard PR — until GitHub Actions recovers, opening a PR will sit in the same BLOCKED state as PR #5135. Per rate-limit operational tier conventions, branch is pushed; PR creation can wait until post-recovery to avoid burning GraphQL on a PR that can't merge anyway.

**Composes with**:

- [`refresh-world-model-poll-pr-gate.md`](../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md) — `gh api rate_limit` REST-free polling confirmed Normal tier
- [`dependency-status-surface.md`](../../../../../.claude/rules/dependency-status-surface.md) — degraded GitHub upstream surfaced via empirical query + WebSearch confirmation
- [`blocked-green-ci-investigate-threads.md`](../../../../../.claude/rules/blocked-green-ci-investigate-threads.md) — applied at the inverted-precondition scope (no green CI possible when CI hasn't fired)
- [`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) — isolated worktree at `/private/tmp/zeta-otto-cli-1202z-cold-boot` with detached HEAD; operator's primary main checkout untouched
- [`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md) — brief-ack #1 with explicit named-dep + concrete artifact (this shard)
- [`tick-must-never-stop.md`](../../../../../.claude/rules/tick-must-never-stop.md) — session-exit non-persistence empirically confirmed at this cold-boot (sentinel was empty)
