mark: Phase 8.2, 8.10 GREEN; create Phase 3 auth tasks

PHASE 8 COMPLETE (10/10 tasks):
- 8.2: X-Service/X-Resource dispatcher ✅
- 8.10: Phase gate - all 5 services routing ✅

Architecture decisions documented:
- Gateway = dumb pipe (Option B)
- SQS: gateway validates JWT (code unverified)
- MinIO, Temporal: native JWT support
- Memory, IAM: service-owned validation
- ConfigMap-based config with Stakater Reloader
- Real integration tests with cluster services

PHASE 3 (Auth) TASKS CREATED (0/3 TODO):
- 3.1: SQS JWT validation vs Authentik JWKS
- 3.2: MinIO native JWT load-test
- 3.3: Temporal JWT jwtKeyProvider configuration

Updates:
- tasks/8.2-x-service-dispatcher.md: marked GREEN
- tasks/8.10-serviceadapter-gate.md: marked GREEN with notes
- tasks/3.1-3.3: new Phase 3 auth tasks
- tasks/INDEX.md: Phase 8 complete, Phase 3 active

-- [ ] `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
+- [x] `internal/server/router.go` X-Service branch before path routing
+- [x] Path-based routes (`/v1/chat/completions`, etc.) unchanged
+- [x] X-Service + X-Resource dispatch to adapter methods
+- [x] 404 for unknown services/resources
+- [x] Auth stub (SQS requires header, others pass-through)
+- [x] HTTP proxying with path rewriting
+- [x] gRPC detection (Temporal, Phase 9)
+- [x] Real integration tests
 
-## Verify
+**Future (not Phase 8.2):**
+- [ ] Blind 5xx retry with backoff (scope: internal/resilience)
+- [ ] {id} path parameter resolution (scope: API design)
+- [ ] Phase 3: JWT signature validation vs Authentik JWKS

+## Notes
+
+- Router moved to dumb pipe (Option B): services validate JWTs independently
+- SQS special case: Gateway checks header (code unverified, Phase 3 will validate signature)
+- MinIO, Temporal: Native JWT support (dumb pipe pass-through)
+- ConfigMap-based config, Stakater Reloader auto-restarts on changes
+- 5 adapters: sqs, workflow (gRPC), memory, s3, iam
