Sylpheed port agent 2d2caccd75 port: check-citations gave a FALSE RED on a freshly pushed peer file
A citation added minutes after the other agent pushed the file it names resolved
NOWHERE, because this scans local refs and the local ref was stale. The citation
was right and the check was wrong. It now says so in the failure text and tells
the reader to fetch before editing.

A check that cries wolf is worse than no check -- and this one had just been
teaching me to distrust a correct citation.

🔴 Separately, my own slip: I ran this as '<check>; git commit' instead of
'<check> && git commit', so the commit landed while the check was red. The guard
was in the command and I had disabled it by punctuation.

"""Do the repo paths cited in `docs/port/*.md` actually resolve?
tools/port/check-citations # assert
tools/port/check-citations --selftest # can it fail?
`audit-kinds` checks citations in `authored/`. Nothing checked the PROSE, and
prose is where this port explains itself. A first run found **37 of 91**
non-resolving, 41 %, in two very different classes:
* **19 on the Decoder's topic branch** — real files, not merged here. Not
errors. A reader in this checkout still cannot follow them, which is worth
reporting and not worth failing on; the fix is a merge, not an edit.
* **7 that resolve NOWHERE** — `docs/BLOCKED.md`, `docs/FORMAT.md`,
`port/manifest.json`, `port/screens/title/*.json`. Left behind by the
monorepo move and the `export/` rename. Those are simply wrong: a reader
following one gets nothing, and nothing had ever told anyone.
So the two classes are separated and only the second fails. A check that failed
on the first would be red for a state nobody in this container can fix, which is
the shape the display guard exists to prevent.
⚠️ THE PEER-BRANCH CLASS IS THE OTHER AGENT'S POINT, TURNED ON MYSELF. They
observed that everything they hand over links into `docs/re/` files that live
only on their branch, so every link they send is dangling from here. The same is
true in reverse and neither of us was counting.
