Folds the good parts of #1412 into this PR and addresses both review-bot reviews (#1412 review 1789, #1414 review 1791): - Everything after the OpenBao store is best-effort. Decode, reconnect, listing and revokes run in reap_superseded(); reap_summary() turns any error into "reap skipped" plus a warning, so rotate_ha_token returns Ok. A failed run would start a second pod (backoffLimit: 1) that keeps the token just stored and its successor and reaps the token consumers still hold until ESO syncs, i.e. the #1081 outage. Two unit tests cover it. - Warn when the replaced token is not named "<client_name> [<6 hex>]": no later run reaps it, so it needs a manual revoke (from #1412). - Staged image rollout (from #1412): only the three HA CronJobs carry the flux-system:secret-rotator marker; the other 17 rotators stay on 2026-07-30 until a manual HA run validates the new binary, then a follow-up adds the marker to them. rotation/kustomization.yaml records the exception. - Merged current main (a6f37e2b,1691a0ac): the Reloader annotations for zone-configurator and speech-to-phrase are already there via #1409.

# Class-B rotation of the cert-manager Cloudflare DNS-01 api-token. Rolls the
|
|
# `Kubernetes Cert-Manager` token value in place via the secret-rotator binary
|
|
# (cloudflare-roll mode): PUT /user/tokens/{id}/value — same id/scope/policy,
|
|
# new value — then patches OpenBao. The admin token + token-id pin live in the
|
|
# shared bootstrap (secret-rotators-bootstrap/cloudflare); this job reads the
|
|
# `token-id` field (external-dns reads `external-dns-token-id`), so the two
|
|
# tokens roll independently.
|
|
#
|
|
# NO Reloader: cert-manager reads the Secret fresh on each DNS-01 challenge, so
|
|
# existing certs are unaffected and no restart is needed. openbao-ns pattern;
|
|
# Cloudflare API reachable via the openbao ns `world` egress. ESO syncs the
|
|
# cloudflare-api-token Secret (ns cert-manager, 10m).
|
|
#
|
|
# IMPORTANT: token-id pins rotation to the DEDICATED single-zone cert-manager
|
|
# token — never the revoked 4-zone `Caddy` token it replaced. If re-pointed,
|
|
# re-verify the id (rolling a shared token breaks its other consumers).
