rockandAdmin Bot	a24e4f7174	feat(sessions): SessionAdapter — REST CRUD for sessions/milestones/episodes (#51) ... 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 --------- Co-authored-by: Admin Bot <[email protected]> Reviewed-on: #51	2026-09-28 01:53:20 +00:00
rockandAdmin Bot	ef5e736673	feat(cag): CAG integration — memory adapter, warmup semaphore, cache-aware routing (#47) ... ## 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 --------- Co-authored-by: Admin Bot <[email protected]> Reviewed-on: #47	2026-09-27 11:16:40 +00:00
rock	aaa9a5d1cb	fix: use query params for workflow_id in Poimen endpoints (#42) ... **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. --------- Reviewed-on: #42	2026-09-26 12:52:19 +00:00

rockandpoimen	f2cff13629	fix(ci): relax namespace validation test + add webhook endpoint test (#30) ... ## 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 --------- Co-authored-by: Poimen <[email protected]> Reviewed-on: #30	2026-09-16 03:08:20 +00:00

Admin Bot	139bc80529	refactor: dispatcher as dumb pipe + add gRPC detection for Temporal ... 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.	2026-08-27 11:16:15 -07:00
