# Deployment gates

The checked-in StatefulSet is a reviewed release input, not evidence of a live
deployment. SQLite is intentionally limited to one replica, `ReadWriteOnce`
storage, and an `OnDelete` update: never start two writers against a copied
database.

**Image: pinned, published, not rolled out.** Both `image:` references already
carry the immutable release digest
`sha256:73333f5ceb55e48192e3095cb2e2a741cdc6ff0be2f18128301072b4a6b6eb9d`
(registry tag `0.1.0`, OCI index; linux/amd64 manifest `sha256:2064d537…`),
pinned at `b51d174`. There is no placeholder left to replace. Both references
MUST stay identical and MUST stay digests — a tag here would let the init
container and the server run different code against one database.

Gates 1 and 2 below are the outstanding ones; nothing is deployed today.

Before applying:

1. Register the exact `approval-engine` audience, caller scopes, and service
   clients in KeyCape. Confirm the in-cluster JWKS endpoint and configured
   issuer match the manifest.
2. Register `approval-engine` as an audit-core sender, add matching audit-core
   ingress, and provision `approval-engine-audit` through the credential owner.
   The Secret must contain key `audit-token`; never commit its value.
3. For a new release only: `make image-release` (build, scan, push — the scan
   gate fails the build on any CRITICAL or HIGH, so a failing scan blocks the
   push), then pin both `image:` references to the returned registry digest and
   run `make deploy-dry-run`. The current digest is already pinned; skip to 4
   unless you are cutting a new image.
4. Take a verified backup. Roll out by deleting the sole pod, then prove
   readiness, restart persistence, outbox drain, heartbeat, and restore.
5. Enable a caller namespace only by applying label
   `railiance.io/approval-engine-client=true`; JWT scope checks remain the inner
   boundary.

The audit-core receiver-side registration, cadence findings, and accepted-count
reconciliation are tracked by `AUDIT-WP-0009-T04/T06/T09` and cannot be closed
from this repository.
