Close remaining in-repo APPROVAL-WP-0002 gaps: drive GH-DEC-2026-003 against the real HTTP surface, fail closed on JWT/human-consume/static-token paths, treat audit 200 duplicates as drained, and ask KeyCape for the production audience and client grants.

# Caller authentication
|
|
|
|
Production accepts only RS256 JWTs verified against KeyCape JWKS with the exact
|
|
configured issuer and `approval-engine` audience. `exp`, `iat`, `sub`,
|
|
`principal_type`, `tenant`, `roles`, `scope`, and `assurance` are mandatory.
|
|
Missing or unverifiable credentials fail closed. The development static-token
|
|
mode is explicit, file-backed, and refused with `--production`.
|
|
The verified `tenant` must exactly match the service's configured store tenant;
|
|
cross-tenant reads and mutations are rejected before object lookup.
|
|
|
|
| Route | Required scope |
|
|
|---|---|
|
|
| create approval | `approval:create` |
|
|
| get approval or claim | `approval:read` |
|
|
| add approval entry | `approval:approve` |
|
|
| revoke | `approval:revoke` |
|
|
| supersede | `approval:supersede` |
|
|
| consume | `approval:consume` and service/agent principal |
|
|
| cadence, outbox, storage | `approval:observe` |
|
|
| explicit heartbeat | `approval:emit` |
|
|
|
|
Create additionally requires `binding.actor == sub`. Approval-entry subject,
|
|
assurance, and evidence reference are derived from the verified JWT, never the
|
|
request body. KeyCape owns client registration and scope grants; approval-engine
|
|
only verifies and enforces them. Requested registrations are:
|
|
|
|
- audience/resource server `approval-engine` with the scopes above;
|
|
- the secrets-engine PEP service client with `approval:read` and
|
|
`approval:consume`;
|
|
- separately governed lifecycle/operator clients with only their needed
|
|
mutation or observation scopes.
|
|
|
|
Client credentials belong in OpenBao/operator custody and must not be placed in
|
|
manifests, logs, State Hub, or this repository.
|
|
|
|
KeyCape's OpenBao service-auth contract currently emits `aud` as the OAuth
|
|
`clientId`. That pattern must not be reused here. Tokens presented to this API
|
|
MUST have resource-server audience `approval-engine`. Requested non-secret
|
|
client fragments are in `docs/keycape-service-registrations.md`.
