tegwick 5a0f4cb5c8 Package canned-prompts for Railiance
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.

# SCOPE
## One-liner
Package and operate the `canned-prompts` hosted registry and index on
Railiance, without moving product ownership into an operations repository.
## In Scope
- `declarations/rapp.yaml` — the managed-workload declaration: composition,
image pin, rollout, smoke and rollback contracts.
- `manifests/` — namespace, external secrets, migration Job, and the runtime
Deployment, Service, ServiceAccount and NetworkPolicies.
- `tools/smoke.sh` — deployment-level verification, delegating the
service-level half to `canned-prompts`.
- Rollout, rollback and the network posture.
## Out of Scope
- What a valid prompt package is, what any endpoint means, the schema and its
migrations, and image publication — all `canned-prompts`.
- PostgreSQL topology, isolation, backups, credential issuance — `rapp-postgres`
and the platform credential broker.
- Who may publish. The service's identity is a single shared token proving
"the operator"; per-publisher identity is an open question upstream, and this
repo must not imply finer control than exists.
## Current State
**Draft.** The package is written and its manifests parse, but nothing is
deployed and `readiness_state` is `draft`. Two things block a first rollout,
both operator actions rather than authoring ones:
- the image has never been published, so no registry digest exists to pin
(`declarations/rapp.yaml` says `pending-publication` rather than carrying a
placeholder that could be mistaken for something deployable);
- database roles and OpenBao credentials are not provisioned.
`workplans/RCP-WP-0002-first-deployment.md` carries both.
## Verification
This repo builds nothing.
```bash
for f in manifests/*.yaml; do python3 -c "import yaml,sys; list(yaml.safe_load_all(open('$f')))"; done
bash -n tools/smoke.sh
NS=canned-prompts ./tools/smoke.sh # against a live deployment
```
## Getting Oriented
- Intent and boundaries: `INTENT.md`
- The declaration: `declarations/rapp.yaml`
- What the service is: `canned-prompts/service/README.md`
- Deployment guide: `repo-manager/docs/RailianceAppDeploymentGuide.md`
