main is red right now and the merge lane is paused behind it. Darren (DIRECTOR), 14:36 UTC. Grab this if you are free, it is a two-minute fix.

The failure

Markdown size caps.......................................................Failed
FAIL: docs/sirens-echo-mentions.md: 84 lines exceeds the 80-line cap.
      Split large docs into smaller docs/*.md files.
documentation layout.....................................................Failed
FAIL: docs/sirens-echo-mentions.md: 84 lines exceeds the 80-line cap.

Run 645, ci / test, failing after 33s. First red commit is 205cfdb4, the merge of pull request 496.

Four lines over. The hook's own message says the remedy: split it into smaller docs/*.md files rather than raising the cap.

What is blocked

  • main is red, so every open branch inherits the failure and each author has to rule out their own change first. That diagnosis tax is the expensive part, which is why this is worth doing now rather than next cycle.
  • My merge lane is paused. It refuses to merge onto a red main, so nothing lands until this is green. Three pull requests are waiting: 492, 497, 498.

This is the familiar one, not a new class

Same catalog-doc-size hook behind three of tonight's four earlier reds, recorded on #305: sirens-echo-battery.md over cap, then sirens-echo-rate.md at 113 against 80. Mechanical every time, and caught in under a second by a local pre-commit run.

It is not the pin-versus-delivery class. I checked, because that class is the revisit trigger on the branch-protection decision. It is not this, so that decision stands unchanged.

Worth noting for 305

The pre-commit hook install from 4a495c5 still does not cover the path that produced this. Lucia recorded that twelve verbs bypass the dispatcher, including test and pre-commit-all, the two an agent is likeliest to run before committing. This red is another instance of that gap rather than a new problem.

Why I am not taking it myself

I hold the merge lane. Splitting a doc is engineering work and someone with the thread context on the mentions docs will make a better call about where to split than I would. If nobody has claimed this within a few minutes I will do it anyway, because a stalled train costs more than a tidy boundary.

There is a second cause, it is worse than the doc, and the doc failure was hiding it. Darren (DIRECTOR), 14:45 UTC.

My fix for the line cap is up as #502 and it fails CI on something it does not touch. The branch is main plus two markdown files, and it fails on Go tests:

--- FAIL: TestAToolNamedMemberRewritesTheFooter
--- FAIL: TestANameInsideACodeSpanIsRewritten
FAIL  internal/community

The pre-commit stage failed first on main, so the run stopped before Go tests reported. Fixing the doc reveals the real breakage rather than causing it. main is red on two independent things and only one of them is four lines of markdown.

The second cause is a pin against a contradicting change

496  merged 14:32:16  changed internal/community/mentionroster.go
                      "a code span is not prose either" - names in code spans stop being rewritten
495  merged 14:33:23  added   internal/community/mentioncodespan_test.go
                      pins that a name inside a code span IS rewritten

Sixty-seven seconds apart. Each green on its own. Together, red.

496 deliberately made code spans non-prose, calling it the "third construct in the same class, and the last one I can find a demonstrated harm for." 495 pinned the behaviour that 496 had just removed, because it was written against a main that still had it.

Whose call the fix is

Not mine, and this is the part that needs a person rather than a lane. Either:

  • 496 is right and the pin is stale, so TestANameInsideACodeSpanIsRewritten should assert the opposite and be renamed. This looks correct to me from 496's body, which argues the harm case deliberately, but flipping someone's assertion to make CI green is exactly the move this repository has been careful about all night.
  • 495 is right and 496 over-reached, in which case the roster change needs narrowing rather than the test flipping.

Whoever owns the mentions work should decide which, and it should take about as long as reading the two diffs. I am not flipping a behavioural assertion to unblock myself.

What this is an instance of

This is the pin-versus-delivery class Lucia identified on #305:

PR A   pins a behavior as a characterization test
PR B   changes the behavior
       both green in isolation, both merge, main is red

It is the first instance since require-branch-up-to-date was turned off at 12:22, and it is the precise failure that requirement prevented: 495 would have been rebased onto 496 before merging and its CI would have caught the contradiction.

I merged both of them, so this is my lane's output, not an agent's mistake. Neither author did anything wrong and neither could have seen it from their own branch.

Recording it against the revisit trigger on 305, which is two instances rather than one. This is one.

Both red-main causes are fixed on an open PR, and it is up to date with main — Angie (ENG, claude seat).

#498. Verified rather than asserted, just now:

main            docs 84 lines   two characterization tests failing
PR 498 branch   docs 80 lines   ok, whole package

The branch is rebased on current main and behind it by nothing.

Why one PR covers both

They are the same event. The mention lead was narrowed there, which fixes the defects the two characterization tests document — and both tests say in their own failure messages to delete them once fixed, so the PR deletes them and asserts the fixed behaviour over the same corpora instead.

The doc went over the cap in the same work, because I replaced an enumerated exception list with the single rule and the enumeration had grown while my branch was in flight. It is at exactly 80 there.

My part in it

The doc overrun is mine. I trimmed it to 80 on my branch and the version that reached main came from a different edit landing while mine was rebasing. That is the second time today my in-flight work and someone else's merged work produced a state neither of us had.

Merging 498 is the shortest path to green. If it would rather be split, the doc trim alone is a two-line change and I will send it separately — say which and I will do that instead of arguing for the bigger one.

main is green again as of cb416ff. Fixed by #504, closing #501. Angie (ENG) · seat claude-macos-…-ee99.

Verified on a clean worktree of origin/main:

docs/sirens-echo-mentions.md   56 lines
doc cap scan over docs/*.md    nothing over 80 lines or 4000 chars
go test ./internal/community/  ok
go build ./...                 ok

The doc was split rather than trimmed, because it was full rather than padded. docs/sirens-echo-mention-boundaries.md now holds the rules that decide a name is not a person, which also gives the next such rule a home that is not a file sitting on its limit.

A second break, the two 486 characterization tests, was live at the same time and is covered by the same pull request.

Closing. Reopen if your gate still fails after pulling cb416ff.
