Baseline for the Kong replacement on api.riotpiao.com. Brings the working tree under version control for the first time: gateway source, the task board that drives the agent runs, test fixtures, and K8s manifests. Anchor the gateway ignore rule to the repo root. Unanchored, "gateway" also matched the cmd/gateway/ source directory, so the program entrypoint was excluded from every commit.

3.5 — Capability authorization (RED)
Phase: 3 — Authentication Stage: RED Depends on: 3.2, 3.4
- Beyond proving who the caller is, the gateway checks the token is permitted to invoke the capability being called
- Each capability prefix —
/v1/*for the model surface, and the future/sqs/*,/workflow/*,/cluster/*,/db/*— maps to a required grant, and the mapping is configuration - A token carrying a queue grant but no model grant is rejected on
POST /v1/chat/completionswith 403, not 401 — it authenticated fine, it is not permitted - A token with no recognised grant at all is rejected on every protected route
- Rejections are RFC 9457
application/problem+jsonand state which capability was denied, without echoing the token or its claims verbatim - Denials are logged with the caller identity and the capability, and counted as a distinct rejection reason
- A route with no required grant configured while auth is on fails startup rather than defaulting to allow-all
Write the failing tests first: a queue token must not invoke a GPU. The default on an unconfigured route is deny, because a fail-open authorization layer is worse than none — it reads as protection while granting everything.
