# user-engine portal on reef-railiance

Exercise status: unknown for the procedures in this runbook; no per-procedure successful-run receipt with operator attribution was established in the 2026-09-05 review. See [procedure inventory](../../../docs/attended-procedure-inventory.md).

**Apply home moved.** The managed package is `rapp-user-engine`. Render,
deploy, verify, and rollback from that repo (`make deploy`,
`make verify-live`). These files are historical migration input, not a current apply or rollback
procedure. In particular, the old runtime mail binding must not be replayed.

This is a stateful `rail-kubernetes` platform workload. It intentionally has
no public Ingress until the KeyCape authorization-code/PKCE edge and
`user-engine-portal` client are configured. Direct access to protected routes
must remain impossible because the application accepts identity only from a
trusted edge marker plus verified claims.

The portal image is published through the activity-core workload-scoped
Forgejo package credential and deployed from
`forgejo.coulomb.social/coulomb/user-engine` by immutable digest. The public
package read was verified without an image pull Secret; publishing still uses
the ExternalSecret-backed credential and temporary client state.

The CloudNativePG operator creates `user-engine-pg-app`, including its `uri`
field. OpenBao is authoritative for the portal edge marker and provisioner
service token at `platform/workloads/user-engine/runtime`. The
`openbao-runtime.yaml` stores and ExternalSecrets deliver those values into the
existing namespaced Secret names without changing application interfaces.

Email delivery now uses email-connect's scoped `user-engine-scoped-mail` ESO
contract owned by the provider; the former shared `mail-token` is revoked and
must not be restored. The legacy `tools/sync-user-engine-delivery-secret.sh`
now refuses before credential or cluster access. Audit sender maintenance must
use the audit-core/Platform owner-reviewed delivery path; the existing audit
Secret is preserved, not rotated or revoked by source retirement. The managed
package's `docs/runtime-contract.md` is the release authority.

The desired runtime also projects a short-lived ServiceAccount token with
audience `flex-auth` at `/var/run/secrets/flex-auth-caller/token`. user-engine
re-reads it per policy decision; it is not a Kubernetes API credential and is
not copied into a Secret. This manifest must be promoted with a user-engine
image that understands `USER_ENGINE_FLEX_AUTH_TOKEN_FILE` and flex-auth desired
state that binds `system:serviceaccount:user-engine:user-engine`. The current
pinned digest predates that coordinated rollout.

Use `make verify-live` from `rapp-user-engine` for current verification.
The former `verify-operability.sh` is retired: its rollback reapplied this
migration tree and its fixed July job names could not prove a current restore.


Rollback sets the Deployment image to the preceding immutable digest.
Database migrations are additive and run before serving; restore uses the
standard CNPG recovery contract once the offsite object-store reference is
attached.
