The three checks that read another repository -- checkFacts, checkQuickstart,
checkReference -- fetched source files from the API's `raw` route, which answers
`Cache-Control: public, max-age=21600`. The CDN in front of Gitea caches that,
so the checks can read a blob most of a working day old.
It bit on cutover day. checkFacts reported
FAIL moduleApi
platform.json says : 1.9.0
website main:server/src/modules/version.js says : 1.6.0
against a `main` that says 1.9.0 -- the served copy was two weeks old
(`cf-cache-status: HIT`, `Age: 15713`, `last-modified: 18 Aug`). No edit in this
repository could have made it pass, and the same run reported a bundle triple
that had already been republished as still current: a stale read fails BOTH
ways, and the false pass is the dangerous one.
The `contents` endpoint answers `private, must-revalidate`, which the CDN
bypasses, so it is always the ref's current blob. The cost is a JSON parse and a
base64 decode. checkReference's canonical-document existence loop already used
it, which is why that half was never affected.
PLAN.md 12 records the finding next to the check it constrains.
