The first lease watch returned FAILED on one sample of 21. That sample was the
instrument: it treated an empty kubectl result as not-ready, so a transient API
hiccup was recorded as an outage. The service returned zero 503s across the
window, with a readiness probe every 5s and 46 minutes of uptime past a
30-minute lease.
Not overriding the verdict by argument — a verdict that can be talked around is
worth nothing. The watcher now distinguishes a failed query from a failed
service and corroborates against the kubelet's probe history, which samples far
more often than once a minute. Promoted from scratch into tools/ so it is
reviewable and re-runnable.
Three checks in this rollout were defective in the same way: live-image-digest-match
degrading to 'not pinned' while a digest was pinned, check_readiness reporting
'database unreachable' for a reachable but unmigrated database, and this
watcher. A verification step that cannot fail correctly is worse than none,
because it is trusted.

Registers the repo with State Hub (agents / practice, prefix RCP-WP) and fills
in the rapp shape.
declarations/rapp.yaml declares a manifest-managed platform service owned by
canned-prompts, bound to rail-kubernetes and reef-railiance, with rollout,
smoke and rollback contracts.
The image pin says `pending-publication` rather than carrying a placeholder
digest. The image builds and was verified locally (canned-prompts
CANP-WP-0006-T06) but has never been pushed, so no registry digest exists. A
placeholder shaped like a real digest would be worse than a sentinel: it could
be mistaken for something deployable.
manifests/ follows the rapp-sbom-nexus shape: namespace labelled for the
postgres client, external secrets from OpenBao, a migration Job, and the
runtime Deployment with a ClusterIP-only Service, dedicated ServiceAccount and
default-deny plus runtime NetworkPolicies.
Three choices worth stating. Credentials arrive as mounted files, never env
vars — an env var holding a password is visible in kubectl describe, in crash
dumps, and to anything that can read /proc. Migrations run as a Job rather than
at start-up, so a schema rollback stays separate from a code rollback and
replicas do not race. Liveness points at /healthz, which checks only that the
process is up: pointing it at a database-dependent path would restart every
replica during a database blip.
Egress is PostgreSQL and DNS only. A package arrives by publish; the registry
never reaches out, so it is given no path to.
tools/smoke.sh checks what only the cluster can answer and calls
canned-prompts' service/tools/smoke.py for health and migration head, rather
than holding a second opinion about whether the service is healthy.
RCP-WP-0002 carries the two operator actions that block a first rollout —
publishing the image and provisioning database roles — and records
per-publisher identity as a decision belonging upstream, which this repo must
not paper over with cluster configuration implying finer control than exists.
