The announcer read only the repositories whose update time moved since its
last pass, less a minute. Opening, reopening or retargeting a pull request
does not move a repository's update time, so a pull request opened more
than a minute after its push was never announced, never checked, and
nothing said so (mesh-sdk #14, 2026-10-09).
- Each pass also looks at every repository holding a pull request updated
since the floor, by the forge's own search; every ten minutes, or when the
search fails, at every repository.
- Every five minutes the forge is asked for every open pull request; one on
a base requiring mesh/merge-gate whose head has had none for ten minutes
is said as the forge failing that pull request's merge check (a provider
standing, ADR 0224), which the controller keeps as a condition, and is
recovered when a check arrives or it closes.
- The client refuses a pull request or issue number that is not one before
asking the forge (a misnamed tool argument sent pulls/NaN).
