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

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

Verify MinIO OIDC config in k8s/infra (not this repo)
Create JWT token with homelab-admins group
Test S3 operations (ListBuckets, GetObject, PutObject)
Add load test to integration suite

Verification

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')

# List buckets
aws s3 ls --endpoint-url https://api.riotpiao.com/ \
  --header "Authorization: Bearer $JWT"

# Get object
curl -H "Authorization: Bearer $JWT" \
  https://api.riotpiao.com/ \
  -H 'X-Service: s3' -H 'X-Resource: list-objects'

Notes

Not Phase 8.2: Phase 8 was routing, Phase 3 is auth verification
MinIO owner responsibility: Verify config in k8s/infra cluster
Gateway responsibility: Pass JWT through unchanged (dumb pipe)
Test coverage: Real JWT token, real S3 operations
