Earlier today Keel's hourly poll caught vaultwarden's deployment in a
window where the `keel.sh/match-tag` annotation wasn't set, fell into
'watch repository tags' mode, and rewrote 1.35.7 -> 1.21.0. Vaultwarden
1.21.0 doesn't have the API endpoints the modern Bitwarden clients call
(/identity/accounts/prelogin/password, /api/devices/knowndevice,
/api/config), so the Chrome extension started 404-ing on login.
Same race shape as the 2026-05-17 authentik/pgbouncer incident. The
fundamental issue: `policy: force` on a semver-pinned tag is unsafe
because Keel happily rewrites the tag string if it can't find a stable
'current tag' to digest-watch.
Fix: switch to `:latest` (the mutable tag vaultwarden publishes for the
newest stable release). Keel now digest-watches `:latest` (safe mode)
and rolls forward on each upstream release. Matches cluster convention
(128 other Keel-managed workloads use the same `:latest` + force +
match-tag pattern).
Also added imagePullPolicy=Always (required with :latest so the kubelet
revalidates the manifest on each rollout instead of using a cached
layer), and extended the lifecycle.ignore_changes to cover the
match-tag annotation and kubernetes.io/change-cause (Keel rewrites
this on every rollout).
Current `:latest` digest -> vaultwarden 1.36.0 (released 2026-05-03).
