A reuse-surface stretch that started as "what needs doing" in a repo with no
open work and turned into a production federation dependency due to break in
eleven days.
The seat is about the pattern underneath it: three separate systems reported
success while being false — a regression test suite that passed with the fix
reverted, a helm upgrade that printed Upgrade complete while shipping the
previous image, and an API reporting stale: false while serving a compose that
no longer matched its own registrations. Each check that caught one took under
a minute.
Also records taking the federated endpoint down for a few minutes, and
overwriting a live registration field without reading it first.
Draft — portrait not yet generated.
