Admin Bot 16ddd6d4ad feat(sessions): sandbox resource — per-session k8s Pod+PVC+Service (§4.15.4)
CI / CI (pull_request) Successful in 2m8s
New X-Resource: sandbox on X-Service: sessions

POST ?session_id=  → CreateOrResume
  1. Ensure PVC workspace-session-<id> (Longhorn 1Gi)
  2. If pod already Running → return DNS (resume path, idempotent)
  3. Ensure pi-session-sandbox NetworkPolicy (shared, created once)
  4. Create Pod pi-session-<id> + Service pi-session-<id>:8787
  5. Wait up to 30s for Pod Ready
  6. Fire-and-forget: merge pod_name/pvc_name/svc_dns/last_active_at
     into session memory_entity summary

DELETE ?session_id= → delete Pod + Service + PVC

Idle reaper goroutine (5min interval, configurable via
SANDBOX_REAPER_INTERVAL_MINUTES): lists pi-session-* pods,
deletes Succeeded/Failed ones, preserves PVCs for resume.

Security: runAsNonRoot/1000, readOnlyRootFilesystem, drop ALL
caps, RuntimeDefault seccomp, automountServiceAccountToken:false.
Resources: 500m/512Mi req, 1/1Gi limit.
NetworkPolicy: egress → DNS + api:8080 only; ingress ← poimen-frontend.

RBAC: Role session-sandbox-manager + RoleBinding in poimen ns.
7 unit tests — all pass (mock k8s server).

rockandAdmin Bot a24e4f7174 feat(sessions): SessionAdapter — REST CRUD for sessions/milestones/episodes (#51)
CI / CI (push) Successful in 3m15s
Closes #50

## Changes

- `internal/sessions/handler.go` — new Handler; 7 endpoints dispatched via `X-Upstream-Path`; writes to `poimen-memory` via `/memory/ingest`; reads from `poimen-graphql` via GraphQL `hybridSearch`/`entity`
- `internal/serviceadapter/session_adapter.go` — `NewSessionAdapter()` + `GetSessionSpec()` with 5 resources
- `cmd/gateway/main.go` — register sessions adapter after memory adapter
- `internal/serviceadapter/adapters.go` — add `sessions` case to factory
- `internal/sessions/handler_test.go` — 30 tests, all pass

## Design

- `X-Service: sessions` + `X-Resource: <sessions|session|milestones|episodes|episode>`
- IDs via query params (`?session_id=`, `?episode_id=`) — dispatcher does not substitute path params
- `episode_id = sha256(session_id+milestone_id+attempt)` per §4.14 Q6
- Content JSON-encoded (injection-safe)
- `tracing.NewTransport` wired for cross-service trace propagation
- GraphQL `errors` array detected, surfaced as 502
- limit capped at 200

rockandAdmin Bot ef5e736673 feat(cag): CAG integration — memory adapter, warmup semaphore, cache-aware routing (#47)
CI / CI (push) Successful in 3m20s
## Summary

Three issues in one PR. Implements Cache-Augmented Generation (CAG) support in the api-gw.

---

### #44 — Memory ServiceAdapter: standing-context resource

- Code-registers `memory` adapter with `standing-context` resource (`POST /memory/standing-context`)
- Fixes dispatcher bug: method-level `Auth.Capability` override now respected (was always using verb-derived capability)
- Auth: `memory:read` required via method-level override; `memory:write` for ingest
- `MEMORY_UPSTREAM_URL` env configures upstream

### #45 — Continuous batching: warmup deprioritisation + per-backend semaphore

- In-memory bounded queue per backend: `VLLM_MAX_QUEUE_DEPTH` slots (default 20)
- Concurrency limiter: `VLLM_MAX_NUM_SEQS` slots (default 4)
- `X-Poimen-Warmup: true` → sleep `WARMUP_DELAY_MS` (default 500ms) before queue entry, strip header, add `X-Priority: low`
- Queue full → 503 immediately, no goroutine pile-up
- Metrics: `warmup_requests_delayed_total`, `queue_full_requests_total` at `/metrics`

### #46 — Cache-aware routing: rendezvous hash + prefix cache hit logging

- `addresses: [...]` YAML field for multi-backend models (backward-compat with `address`)
- `X-Poimen-Cache-Key` header → rendezvous-hash backend selection (same key = same GPU)
- No cache key → round-robin
- Failed backend excluded 30s; next-highest-score fallback
- `vllm-num-cached-tokens` response header captured → `vllm_prefix_cache_hit_tokens_total` counter + structured log

## Verification

```
go build ./...    ✅
go vet ./...      ✅
go test -race ./... ✅ (all packages, 0 races)
```

## Reviewer verdicts

- reviewer-sre: SIGN-OFF
- reviewer-quality: SIGN-OFF

## Non-blocking findings (🟡🔵 only)

- `getOrCreateTransport` not goroutine-safe by design; pre-population invariant documented
- `time.Sleep(warmupDelay)` holds goroutine; context-cancel alternative left as TODO
- OTel trace_id not propagated into CAG log events (existing gap)

Closes #44 Closes #45 Closes #46

rock aaa9a5d1cb fix: use query params for workflow_id in Poimen endpoints (#42)
CI / CI (push) Successful in 3m7s
**Root cause:** ServiceAdapter dispatcher sets X-Upstream-Path to template strings like `/v1/poimen/executions/{id}/stream` with literal `{id}`. The handler extracted `{id}` as the workflow ID instead of the actual value.

**Fix:** All handlers read `workflow_id` from query params (`?workflow_id=xxx`). Paths changed to flat resource names without path parameters.

**API contract:**
```
GET  /executions                         — list
GET  /executions/detail?workflow_id=xxx   — describe
GET  /executions/history?workflow_id=xxx  — history
GET  /executions/stream?workflow_id=xxx   — SSE
POST /executions/signal?workflow_id=xxx   — signal
DELETE /executions/detail?workflow_id=xxx — terminate
```

All accessed via `X-Service: poimen` + `X-Resource: <name>` headers.

rockandpoimen f2cff13629 fix(ci): relax namespace validation test + add webhook endpoint test (#30)
CI / CI (push) Failing after 18m58s
## Problem
CI integration test runs against the **live deployed gateway** (old image). The namespace validation test expects 400, but old image returns 404 → CI never promotes new image → chicken-and-egg.

## Fix
- Accept 400 or 404 for namespace test during rollout
- Add unit test confirming WorkflowAdapter returns 400 (passes locally)
- Add integration test for `POST /v1/webhooks/forgejo`

## Tests
- `go test ./internal/serviceadapter/... -run TestWorkflowListRequiresNamespace` passes locally

30e0a83a50 feat(network): SSE optimization for local LLM streaming (#31 #32 #33) (#26)
CI / CI (push) Successful in 3m35s
Addresses three critical network issues for LLM streaming performance:

**#33 Disable proxy buffering for SSE**
- Add X-Accel-Buffering: no header to response
- Tells nginx/Ingress to stream events immediately instead of buffering

**#32 HTTP/2 multiplexing for concurrent streams**
- Enable HTTP/2 in server config via http2.ConfigureServer()
- Increase MaxConnsPerHost to 10 for better concurrency
- Allows multiple concurrent LLM requests without blocking

**#31 TCP backpressure for streaming LLM responses**
- Set TCP_NODELAY on dialer to disable Nagle's algorithm
- Reduces latency by sending small packets immediately
- Critical for low TTFT (time-to-first-token) under load

**Tests added:**
- TestTCPBackpressure: Verifies TCP backpressure handling with slow client
- TestConcurrentSSEStreams: Confirms HTTP/2 multiplexing works correctly

poimenandrock 74ecfe7107 feat(serviceadapter): enforce JWT auth on X-Service dispatch (#16)

Admin Bot 9d9395d938 feat: Phase 3.1 - SQS JWT validation against Authentik JWKS
CI / Vet, test, build (push) Successful in 2m4s
CI / Build and push image (push) Failing after 18s
Implements gateway-level JWT validation for SQS requests:
- Validates JWT signature against Authentik JWKS
- Verifies claims: iss, aud, exp, nbf (with 60s skew)
- Checks 'permissions' claim for sqs:read/sqs:write/wildcard
- Returns 403 with error details on validation failure
- JWKS caching with 15min TTL and auto-refresh on key rotation

Architecture:
- SQS: Gateway validates JWT (kmsvc code unverified)
- MinIO, Temporal: Native JWT support (pass-through)
- Memory, IAM: Service-owned JWT validation

Integration tests added:
- Reject requests without Authorization header (403)
- Accept requests with valid JWT from Authentik
- Pass through Authorization header unchanged for other services

Uses github.com/MicahParks/keyfunc/v2 for JWKS handling:
- Automatic refresh every 15 minutes
- On-demand refresh if kid not found
- Handles RS256 signatures

CI / Build and push image (push) Successful in 45s
Auth strategy clarified per service:
- SQS: Gateway validates JWT (kmsvc code unverified, needs Phase 3)
- MinIO: Native JWT/OIDC support (validates itself, Phase 3: load-test)
- Temporal: Native JWT via jwtKeyProvider (Phase 3: configure)
- Memory, IAM: Services validate JWTs (dumb pipe)

SQS now requires Authorization header at gateway.
Phase 3 will implement actual JWT signature validation against Authentik.

Admin Bot 139bc80529 refactor: dispatcher as dumb pipe + add gRPC detection for Temporal
CI / Vet, test, build (push) Canceled after 24s
CI / Build and push image (push) Canceled after 0s
BREAKING CHANGE: Gateway no longer validates JWTs at dispatcher level.
Each upstream service (MinIO, Authentik, Temporal) validates bearer
tokens independently. Gateway passes Authorization header through unchanged.

Changes:
- Removed JWT validation from Dispatcher
- Removed internal/auth JWT validator usage
- Added gRPC URL scheme detection (grpc://)
- Added temporal-frontend with gRPC config (returns 501 not-implemented)
- All adapters now auth: required: false (services validate own tokens)
- Gateway is now a transparent routing layer, not auth gateway

gRPC forwarding requires grpcproxy middleware (future Phase 9).
For now, gRPC clients should connect directly to temporal-frontend:7233.
