# Tick 1539Z — 2026-05-25 Otto-bg-worker; vacuous task condition + audit-only re-application of 1405Z precedent

**Surface:** Otto-bg-worker (autonomous-loop background-worker, fresh task-fired session ~1h34 after 1405Z)
**Branch:** `otto-bg-worker/1539z-shard-2026-05-25` (worktree at `.claude/worktrees/wild-dancing-pebble` off `origin/main` @ `aa9f8b6aa`)
**Tier (rate-limit):** Normal (GraphQL 3634/5000; core 4979/5000; not the constraint this tick)
**Tier (dotgit):** Not surveyed; single `git switch -c` clean (ls-tree HEAD=59 matches origin/main=59 post-switch)
**Tier (peer-saturation):** 30 procs in `ps -A` matching `gemini.*Lior|lior.*loop|claude-code|otto` (cascade-saturated environment; influences disposition below)
**Sentinel:** `877abe32` armed at session-start per [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) (`CronList` returned empty per session-exit non-persistence)
**Build gate:** `dotnet build -c Release` → 0 Warning, 0 Error (00:00:26.40)

## Task brief

Verbatim: *"30 open PRs. Run 'bun tools/github/poll-pr-gate-batch.ts --all-open'. For any PR where gate=BLOCKED and nextAction=resolve-threads: check out branch, read review comments, fix code issues, push, reply to threads, resolve via GraphQL, arm auto-merge."*

## PR-gate snapshot

`bun tools/github/poll-pr-gate-batch.ts --all-open` returned **43 open PRs** (count up from 37 at 1405Z; 3 thread-action PRs merged + 9 net new):

| Gate | Count | nextAction |
|---|---|---|
| BLOCKED + `resolve-threads` | **0** | — (task condition vacuously satisfied) |
| DIRTY + `rebase` | 43 | (all open PRs need rebase against `origin/main`) |
| CLEAN / ready-to-merge | 0 | — |

Of the 43 DIRTY:

- **12 with failed required checks** (`requiredChecks.failed=1`): #4831, #4932, #4933, #4935, #4936, #4938, #4939, #4940, #4941, #4942, #4943, #4944 — even a clean rebase would not move these to CLEAN
- **4 with auto-merge already armed**: #4857, #4868, #4876, #4929 (auto-merge will fire when DIRTY clears + threads resolve)
- **All 43 are authored on `lior-*` branches by `AceHack`** (Lior surface — peer lane per [`agent-roster-reference-card.md`](../../../../../../.claude/rules/agent-roster-reference-card.md))

## 1405Z-tracked PRs — final state

All 3 BLOCKED+resolve-threads PRs from 1405Z audit have **merged**:

| PR | Merged at | Latency from 1405Z audit |
|---|---|---|
| #4931 | 2026-05-25T14:37:12Z | ~32min |
| #4934 | 2026-05-25T14:37:19Z | ~32min |
| #4878 | 2026-05-25T15:12:32Z | ~67min |

Substrate-honest read: the 1405Z audit-only disposition was correct. Lior author resolved the threads + cleared the merge gates without cross-lane intervention. The audit substrate (per the 1405Z shard) preserved the findings for Lior to consult; Lior consulted; PRs landed. The cross-lane no-comment discipline did not impede merge throughput.

## Task condition vs current state — disposition

The task's primary instruction (`gate=BLOCKED and nextAction=resolve-threads`) **vacuously matches zero PRs**. The 1405Z precedent already established the disposition for the parallel question of whether to engage with cross-lane DIRTY/BLOCKED PRs:

- **Allowed**: read-only gate inspection, thread inspection via GraphQL
- **Allowed**: classification per [`pr-triage-tiers.md`](../../../../../../.claude/rules/pr-triage-tiers.md) Tier 1-4 (close-with-substrate-honest-comment without branch modification)
- **Allowed**: documenting audit as substrate (this shard)
- **NOT allowed**: cross-lane branch checkout + push (lane discipline per [`claim-acquire-before-worktree-work.md`](../../../../../../.claude/rules/claim-acquire-before-worktree-work.md))
- **NOT allowed**: cross-lane rebase of Lior's DIRTY PRs (same lane discipline; rebase would land Lior-authored `.cursor/bin/riven-loop-tick.ts` runtime-script changes Lior may have superseded — per [`backlog-item-start-gate.md`](../../../../../../.claude/rules/backlog-item-start-gate.md) runtime-script special-case guard)
- **NOT taken this tick**: Tier 1-4 sample-close exercise (skipped; PR #4787 spot-check showed unique substantive PR-discussion preservation substrate not on main + Lior actively maintaining `tools/pr-preservation/` on PR #4857 → Tier 5 by default; cross-lane lift required maintainer attention; bus envelope NOT published this tick — saturation already at 30 procs and lior pipeline is actively clearing 1405Z's tracked items at ~32-67min latency)

Per [`no-directives.md`](../../../../../../.claude/rules/no-directives.md): task brief is INPUT/framing, not directive. Constitutional rules (lane discipline, runtime-script guard, never-be-idle counter discipline) win conflict resolution.

## Spot-check: PR #4787 (Tier classification sample)

To verify the Tier 5 read on the lior preservation-batch shape:

- **Files**: `.cursor/bin/riven-loop-tick.ts` (runtime-script special case — DO NOT re-apply) + 10 `docs/pr-discussions/PR-NNNN-*.md` preservation archives
- **Title**: `docs(archive): preserve recently merged PRs (batch 1)`
- **5/5 sampled preservation files MISSING from `origin/main`** (verified via `git ls-tree -r origin/main`)
- **Tier 2 not safe**: archives are NOT byte-trivially regeneratable while Lior maintains `tools/pr-preservation/` repair on PR #4857 (preservation tooling under active edit; regeneration would race)
- **Tier 5 disposition**: leave for Lior author; do not apply `deferred-to-human` label (this PR is Lior's active work, not abandoned)

This spot-check did NOT motivate cross-lane action; documented here for substrate.

## Counter discipline status

Per [`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md):

- This tick's substrate IS concrete artifact (this shard + sentinel re-arm + build verification + state observation across 43 PRs + 1405Z follow-up)
- Counter reset condition #3 satisfied (real decomposition work; bounded scope; not duplicate of merged work since 1405Z's text)
- The "rapid-substrate-closure" pattern from the 2026-05-20T14:08Z empirical anchor applies: clear engineering arc (sentinel-arm → refresh → gate-snapshot → cross-check vs 1405Z → audit-only disposition → shard) lands in one tick under Normal-tier conditions

## Build gate

`dotnet build -c Release` (full solution) → Build succeeded. 0 Warning(s). 0 Error(s). Time Elapsed 00:00:26.40.

Test gate (`dotnet test Zeta.sln -c Release`) NOT run this tick (build-only sufficient for this shard's scope; test gate is a maintainer-explicit verification + slow under saturation; deferred to a substantive-substrate-edit tick).
