auto-loop-11 tick-history row — PR #101 MD038 fix + PR #93 three-finding all-reject + PR #93 merge

[AceHack]

Appends row 121 to docs/hygiene-history/loop-tick-history.md for auto-loop-11.

Summary

• PR auto-loop-10 tick-history row — unblock tick-history PR chain via Copilot review address + PR #99 redundancy-close #101 MD038 fix: nested backtick-escape code span in row 120 produced markdownlint MD038 failure at col 886. Fixed via plain-prose replacement + single clean code ref (docs/CONTRIBUTOR-PERSONAS.md); commit 1dc4de5; Copilot thread resolved with fix-commit reference.
• PR Round 44: absorb Copilot-products-split arc into ROUND-HISTORY #93 three-finding all-reject: refreshed against advancing main, then addressed 3 Copilot findings:
  • P1 rationale mismatch + self-contradicting suggestion — finding cited content not in current diff (prior c1a4863 rewrote it), suggestion contradicted canonical form from meta-wins-log.md.
  • P2 partial-meta-win — file already matches canonical form (space, not hyphen).
  • P2 reviewer-robot "inconsistency" — follows English attributive-adjective convention correctly (a reviewer robot noun / reviewer-robot contract attributive compound); matches pattern in canonical HARNESS-SURFACES.md.
    All three rejected with principled reasoning; threads resolved via GraphQL.
• PR Round 44: absorb Copilot-products-split arc into ROUND-HISTORY #93 merged: auto-merged as 4819e22 mid-tick.
• PR auto-loop-10 tick-history row — unblock tick-history PR chain via Copilot review address + PR #99 redundancy-close #101 refreshed: BEHIND after PR Round 44: absorb Copilot-products-split arc into ROUND-HISTORY #93 landed; refreshed + pushed 62076e4, awaiting CI on refresh.

New rejection-grounds cataloged

• Stale-rationale — finding references content a prior branch commit already rewrote.
• Self-contradicting-suggestion — replacement contradicts its own rationale or a sibling finding.
• Grammatical-attributive-adjective — "inconsistency" that follows English hyphenation convention, not typo.

New failure-mode documented

• Nested code-span with backslash-escaped backticks produces malformed markdown (passes visual inspection, fails MD038 at render time). Mitigation: never nest code spans within code spans.

Base-point

Fresh branch off origin/main with PR #101's branch (land-tick-history-autoloop-10-append HEAD 62076e4) merged in locally to stack row 121 after the pending row 120 — same stacked-dependency pattern documented in auto-loop-9 and auto-loop-10 rows.

Pre-check grep: EXIT=1 clean. Markdownlint: clean locally.

Pull request overview

Appends the next autonomous-loop tick-history entry (auto-loop-11) to the loop tick history log, continuing the append-only narrative for Round 44’s operational maintenance and Copilot-review resolution work.

Changes:

• Added tick-history row 121 (auto-loop-11) immediately after row 120.
• Row 121 documents the MD038 mitigation (nested code-span failure-mode) and the PR #93 Copilot-thread all-reject resolution/merge narrative.

[Copilot]

The reference docs/research/meta-wins-log.md:83 bakes in a specific line number, which is likely to drift and recreates the same brittleness this row describes fixing elsewhere. Prefer citing the file (and optionally the section/bullet text like the “Retrospective” list item for “partial meta-win”) without a line-number anchor.

[Copilot]

“maintainer-cant-spell baseline memory” reads like a named artifact, but there’s no corresponding memory file/reference in-tree, which makes the provenance hard to trace later. Consider either linking to the specific memory entry that establishes this baseline (e.g., the maintainer’s typing/spelling-channel disclosure) or rephrasing so it’s clearly a general observation rather than an implied canonical memory name.

Closing as redundant — content already on main.

State narration

PR #103 (auto-loop-12 tick-history row) was stacked on this branch via local `git merge --no-edit origin/land-tick-history-autoloop-11-append` to place the auto-loop-12 row after the auto-loop-11 row. When PR #103 squash-merged as `822f912`, GitHub's squash operation carried BOTH the auto-loop-11 row (row 121) AND the auto-loop-12 row (row 122) onto main together.

Why this PR would now REVERT landed content if merged

Verified via `git diff --stat origin/main..origin/land-tick-history-autoloop-11-append`:

```
.github/workflows/gate.yml | 25 +------------------------
docs/GITHUB-SETTINGS.md | 16 ++--------------
docs/hygiene-history/loop-tick-history.md | 1 -
tools/hygiene/github-settings.expected.json | 1 +
```

This branch's base is behind PR #46 (gate-split merge `2053f04`) and PR #103 (auto-loop-12 row `822f912`). Auto-merging this PR would undo both:

• PR gate: split macOS leg to forks only; drop (macos-14) from LFG required checks #46's macos-leg-on-forks-only gate split.
• The auto-loop-12 tick-history row.

Auto-merge has been disabled on this PR before the close.

Third observation of the stacked-dependency-redundancy pattern

Auto-loop-10 closed PR #99 as redundant after PR #100's squash carried its content. Auto-loop-12 closed nothing. Auto-loop-13 closes this PR #102 for the same reason. Pattern generalizes: when a stacked-dependency PR lands upstream via squash, the base PR becomes redundant and must be closed, not merged — because its branch-base is older than the squash-merged state and a subsequent merge would revert landed content.

Auto-loop-13 surfaces this as a new end-of-PR-loop hygiene step (complementing the zero-delta check from auto-loop-10): after every PR merge, audit the stack: any downstream PR whose content is now on main must be closed with redundancy-comment, not merged. The `git diff --stat origin/main..origin/` check is the diagnostic — if the diff shows REMOVALS of content that's on main, the branch is stale-not-ahead and must close.
