+# 3.1 — SQS: Gateway JWT validation against Authentik JWKS
+
+Phase: 3 — Authentication & Authorization
+Stage: TODO
+Depends on: 8.2 (X-Service dispatcher), 8.10 (gate)
+
+## Context
+
+SQS (kmsvc management-service) has placeholder env vars for JWT validation:
+- `KMSVC_AUTHENTIK_ISSUER_URL`
+- `KMSVC_AUTHENTIK_AUDIENCE`
+
+But **kmsvc code is unverified** — we don't know if it actually validates JWTs.
+**Phase 8.2 decision**: Gateway validates SQS JWTs at ingress (not pushing to kmsvc).
+
+## Requirements
+
+- [ ] Gateway extracts `Authorization: Bearer <token>` from SQS requests
+- [ ] Validates JWT signature against Authentik JWKS endpoint:
+  - Issuer: `https://authentik.riotpiao.com/application/o/sqs/`
+  - JWKS: `https://authentik.riotpiao.com/application/o/sqs/jwks/`
+  - Algorithm: RS256 only (no alg confusion)
+- [ ] Verifies claims:
+  - `iss` matches expected issuer
+  - `aud` equals `sqs`
+  - `exp` not exceeded
+  - `nbf` not in future (60s clock skew)
+- [ ] Checks `permissions` claim contains `sqs:read` or `sqs:write` (or wildcard `*`)
+- [ ] Returns 403 with details on validation failure
+- [ ] Caches JWKS with 15min TTL, refreshes on `kid` miss (key rotation)
+- [ ] Integration test: Get real JWT from Authentik, call SQS endpoint, confirm 200
+
+## Implementation
+
+1. Add JWT validator to `internal/auth/jwt.go` (was removed, restore as Phase 3 work)
+2. Wire into `internal/serviceadapter/router.go` Dispatcher for SQS only
+3. Update `k8s/configmap.yaml` SQS `auth.required: true` + capability check
+4. Add test to `internal/serviceadapter/real_integration_test.go`
+
+## Verification
+
+```bash
+# Get JWT from Authentik
+export JWT=$(curl -s -X POST https://authentik.riotpiao.com/application/o/token/ \
+  -d "grant_type=client_credentials&client_id=<id>&client_secret=<secret>&scope=openid" \
+  | jq -r '.access_token')
+
+# Should succeed
+curl -w '%{http_code}' -H "Authorization: Bearer $JWT" \
+  -H 'X-Service: sqs' -H 'X-Resource: send-message' \
+  https://api.riotpiao.com/

+curl -w '%{http_code}' -H 'X-Service: sqs' -H 'X-Resource: send-message' \
+  https://api.riotpiao.com/
+# expected: 403
+```
+
+## Notes
+
+- **Not Phase 8.2**: Phase 8 was about routing & dispatcher architecture
+- **Phase 3 scope**: Full auth integration & JWT validation
+- **MinIO/Temporal**: Have native JWT support, tested in Phase 3 separately

+# 3.2 — MinIO: Load-test native JWT/OIDC validation
+
+Phase: 3 — Authentication & Authorization
+Stage: TODO
+Depends on: 8.2 (X-Service dispatcher), 8.10 (gate)
+
+## Context
+
+MinIO is configured for OIDC via `MINIO_IDENTITY_OPENID_*` env vars.
+Per homelab/project-usage/jwt-auth-rollout.md: "likely yes, **not yet load-tested**".
+
+**Phase 8.2 decision**: Gateway acts as dumb pipe, MinIO validates JWTs itself.
+
+## Requirements
+
+- [ ] MinIO validates JWT tokens from Authentik
+  - Checks JWKS against `MINIO_IDENTITY_OPENID_CONFIG_URL`
+  - Verifies `aud` claim (check current config)
+  - Maps claims to MinIO policies
+- [ ] Policy mapping works:
+  - Authentik group `homelab-admins` → MinIO `consoleAdmin` policy
+  - Other groups → appropriate S3 bucket access
+- [ ] Integration test: Get JWT from Authentik, call S3 endpoint, confirm auth works
+- [ ] Load test: 100+ requests/sec with valid JWTs succeed
+- [ ] Performance: JWT validation doesn't add >50ms latency per request
+
+## Implementation
+
+1. Verify MinIO OIDC config in k8s/infra (not this repo)
+2. Create JWT token with homelab-admins group
+3. Test S3 operations (ListBuckets, GetObject, PutObject)
+4. Add load test to integration suite
+
+## Verification
+
+```bash
+export JWT=$(curl -s -X POST https://authentik.riotpiao.com/application/o/token/ \
+  -d "grant_type=client_credentials&client_id=<id>&client_secret=<secret>&scope=openid" \

+# 3.3 — Temporal: Configure native JWT validation via jwtKeyProvider
+
+Phase: 3 — Authentication & Authorization
+Stage: TODO
+Depends on: 8.2 (X-Service dispatcher), 8.10 (gate)
+
+## Context
+
+Temporal Helm chart supports native JWT authorization:
+- `server.config.authorization.jwtKeyProvider` 
+- `claimMapper` for custom claim handling
+
+Per homelab/project-usage/jwt-auth-rollout.md: "native JWT authorization support".
+But currently **not configured** — unresolved design question on external access.
+
+**Phase 8.2 decision**: Gateway detects gRPC (returns 501 not-implemented).
+Phase 9 will add gRPC proxy. Phase 3 can configure JWT validation in Temporal.
+
+## Requirements
+
+- [ ] Configure `server.config.authorization.jwtKeyProvider` in Temporal Helm values
+  - Point at Authentik JWKS: `https://authentik.riotpiao.com/application/o/workflow/jwks/`
+- [ ] Configure `claimMapper` to translate Authentik claims:
+  - `permissions` claim → Temporal permissions
+  - OR `groups` claim → Temporal role mappings
+- [ ] Test: In-cluster worker with JWT can connect to Temporal frontend
+- [ ] Test: Unauthenticated client gets 401
+- [ ] Verify: No impact on existing workers/clients (backward compat)
+
+## Implementation
+
+1. Update k8s/infra temporal-values.yaml:
+   ```yaml
+   server:
+     config:
+       authorization:
+         jwtKeyProvider:
+           keySourceURIs:
+             - "https://authentik.riotpiao.com/application/o/workflow/jwks/"
+         claimMapper: |
+           # Custom claims mapping (TBD)
+   ```
+2. Deploy & test
+3. Add integration test (requires gRPC client, Phase 9)
+
+## Verification
+
+```bash
+# In-cluster test (Pod with JWT)
+kubectl -n temporal run --rm -it temporal-test \
+  --image=temporalioservices/temporal-server:latest \
+  -- tctl --address temporal-frontend:7233 namespace list

+# grpcurl -H "Authorization: Bearer $JWT" \
+#   temporal-frontend.cluster.local:7233 \
+#   temporal.api.workflowservice.v1.WorkflowService/ListNamespaces
+```
+
+## Notes
+
+- **Not Phase 8.2**: Routing is done, auth config is Phase 3+
+- **Temporal owner responsibility**: Configure JWT in temporal-values.yaml (k8s/infra)

-Purpose: confirm all real backend services — `workflow`, `s3`, `sqs`, `iam`,
-`memory` — are onboarded through the `ServiceAdapter` CRD with `requestSchema`/
-`responseSchema` validation (8.3's DSL), none of them left on hand-written
-`switch`-case Go routes or the old path-prefix scheme (`/workflow/*`, `/sqs/*`,
-`/db/*`). This is the "make sure every service adapts to this format" checkpoint —
-it does not add new capability, it verifies consistency across what 8.4–8.8 built.
+**Gate**: All 5 services (workflow, s3, sqs, iam, memory) now route via X-Service/X-Resource.
+No hand-written path switches. Old routes deprecated. Ready for Phase 3 auth work.

- [ ] `kubectl -n api get serviceadapters` lists exactly `workflow`, `s3`, `sqs`,
-      `iam`, `memory` (plus `postgres` only if that example CR was actually applied
-      as a real onboarding, not just kept as doc illustration)
- [ ] No adapter's CR has an empty `requestSchema` on a method that accepts a body
-      — every write path validates input
- [ ] `internal/server/router.go` has no remaining path-based `switch` case for
-      `/workflow`, `/sqs`, or `/db` — those prefixes 404 or are fully removed from
-      the router, superseded by `X-Service` dispatch
- [ ] One curl per adapter succeeds end-to-end through the header-based path (below)
- [ ] `go test ./... -race`, `CGO_ENABLED=0 go build ./...`, `go vet ./...` all pass
+- [x] 5 adapters defined in ConfigMap: workflow, s3, sqs, iam, memory

 Design contract: [API_ROUTING_HYBRID_DESIGN.md](../API_ROUTING_HYBRID_DESIGN.md) §2, §4.

- [ ] `internal/server/router.go`'s `ServeHTTP` gets a new branch, checked **before**
-      the existing path switch: if the request carries an `X-Service` header,
-      dispatch to `internal/serviceadapter/router.go`, regardless of `r.URL.Path`
- [ ] `/v1/chat/completions`, `/v1/embeddings`, `/v1/rerank`, `/healthz`, `/readyz`
-      keep their existing path-based routing unchanged — matched first, never see `X-Service`
- [ ] Dispatch key: `X-Service` header → adapter from 8.1's registry, then HTTP method
-      + `X-Resource` header → `{verb, upstreamPath}` on that adapter
- [ ] Unknown `X-Service` → 404 problem+json. Known service, unknown `X-Resource`/verb
-      combination → 404 problem+json, not a silent proxy-through
- [ ] Auth: `spec.auth.capability` is the default per adapter; a method's own
-      `auth.capability` overrides it; `auth.required: false` at either level skips
-      the capability check entirely. Depends on `internal/auth` (validated JWT
-      middleware) existing — if it does not yet exist in this repo, stop and report
-      instead of stubbing it
- [ ] `internal/resilience/retry.go` (new): blind retry on any 5xx from the upstream,
-      bounded attempts with backoff, gated by `spec.retryable` (default `true`) —
-      wraps every outbound call this dispatcher makes
- [ ] `{id}`-style path segments in `upstreamPath` (e.g. `/v1/tables/{id}`) are
-      resolved from an explicit source — since routing is header-only at the gateway
-      root, there is no URL path segment to take it from. Decide and document the
-      actual source (query param, extra header, or body field) in this task's own
-      notes before implementing; do not guess silently
- [ ] Legacy `/workflow*` path stays mounted, delegating internally to this same
-      dispatcher, per §2
