Skip-if-exists is keyed on our own source, so an artifact whose source stops moving stops picking up base-image updates. `agent/` last changed 2026-07-17; every push since has correctly declined to rebuild it, which also means it will serve that day's nvidia/cuda layers indefinitely. A `schedule:` trigger, Sunday 06:00 UTC, away from CI-runner's Monday security sweep so the two are never diagnosing each other. #3154's blocking open question is dissolved rather than answered. It was written when the identity was a `r-<revision>` TAG, and asked how the next ordinary push could avoid repointing :latest back off the refresh. Milestone 318 replaced that tag with a LABEL, and #3183 made the repoint step exclude its source tag so the label stays readable. Excluding the source is what also keeps a refresh from being undone: on the next main push the reuse check hits, :latest is not rewritten, and the new :c-<sha> is written FROM the refreshed :latest. To be verified by digest, not by this argument. Four decisions, each commented where it lives: * It builds `main`, not the branch that triggered it. Forgejo registers a cron from the default branch — `dev` here — so a scheduled run arrives with github.ref on dev, and a refresh of :dev would be refreshing the one channel that is rebuilt constantly anyway. The ref is decided once in a top-level `env: BUILD_REF` that all four checkouts take. Deriving it per job would let the halves disagree: sign-extension would derive dev's extension version while build-web bundled main's, and the release download would 404 on a version that exists perfectly well. * It publishes only the channel tag. :c-<sha> for main's HEAD already names the bytes that commit built; re-pushing it over refreshed layers would break the one tag rule 145 makes immutable, and it is the rollback unit — so the breakage would surface on the day somebody needed it. The repoint step needs no schedule case: the tag list is the channel tag alone, SOURCE is the only entry, it is excluded as always, and the step correctly does nothing. * It bypasses reuse by construction, since it rebuilds the same source and fc.revision always matches. Checked in the reuse step beside force_build, so one decision still drives both the build and the repoint. * `pull: true`, on the scheduled path only, is the actual mechanism. A moved base tag changes the FROM layer's cache key and everything above it rebuilds; an unmoved one is satisfied by the registry cache and the refresh is a ~13s no-op that republishes nothing. That no-op is the point — :latest should change when there is something new in it, not every Sunday. The known lag, left deliberately: an apt package update while the base tag stands still is not caught, and closing it needs no-cache: true, which buys weekly churn for it.
