I-4 said 'never a one-way door' and had no implementation. Now it does.
- ensure the GitHub counterpart exists (idempotent), then ask Gitea to keep
it in step with sync_on_commit=True. An hourly timer means an hour of work
can be the thing you lose, and that window is invisible until it costs you.
- mirror status reports what is TRUE including 'we do not know'. An
unconfigured mirror reports unconfigured, NEVER healthy — same posture as
me-fleet.ts refusing to say 'online' when it only knows 'registered'.
- lag past the threshold is a P2, not a shrug. A mirror nobody checks is a
belief, not a backup, and this ecosystem already lost 37 days to a canary
everyone assumed was fine.
Gitea owns the replication rather than a hand-rolled loop, because a background
job that fails silently is exactly how the registry's integrity refresh spent
its entire life calling a 404 and incrementing a counter instead of raising.
Also fixes a real bug I had written myself: list_versions derived the Gitea
namespace from the CALLER, which is correct only while the caller is the owner
and addresses the wrong namespace the moment a collaborator asks — surfacing as
'not found', which is the hardest kind of bug to see. Now derived from the repo,
with a test that keeps it that way.
