43 outdated/completed task files (phases 0-8) - All design docs (REQUIREMENTS, ADR, routing design, etc) - Phase-specific docs (temporal, JWT, tool calls, testing guides) - Redundant API docs (API-llm, API-sqs, SERVICE-USAGE) Kept: README.md (project overview) New: Comprehensive API.md - Single source of truth for api.riotpiao.com - All services in one place: LLM, workflows, queues, memory, IAM, S3 - Complete request/response examples - Authentication via JWT bearer tokens + capabilities - Error handling (RFC 9457) - Rate limits, timeouts, status codes - Real-world examples (RAG pipeline, workflow orchestration) Benefits: ✅ Developer finds everything in API.md ✅ No duplicate/stale docs ✅ Reduced maintenance burden ✅ Single source of truth --- API.md | 1325 ++++++++--------- API_ROUTING_HYBRID_DESIGN.md | 532 ------- INTEGRATION_TESTS.md | 122 -- JWT_VS_RANDOM_TOKEN.md | 486 ------ LLM_TOOL_CALLS.md | 499 ------- REQUIREMENTS.md | 367 ----- TEMPORAL_GRPC_MIGRATION.md | 176 --- TEMPORAL_USAGE.md | 1210 --------------- TESTING_GUIDE.md | 560 ------- docs/API-llm.md | 324 ---- docs/API-sqs.md | 262 ---- docs/MIGRATION-kong.md | 143 -- docs/SERVICE-USAGE.md | 542 ------- .../ADR-0001-retire-kong-for-go-gateway.md | 136 -- tasks/0.1-module-and-entrypoint.md | 32 -

This -revision reflects decisions made while reviewing the repo against the actual state: -`internal/auth/` was empty, `s3`/`sqs`/`iam` didn't exist as handlers, and only a -body-action `POST /workflow` endpoint was real. Four extensions were decided: -CRD-driven service onboarding, `X-Resource`-based REST verbs replacing body actions, -unified JWT auth (bearer token or service-account password, one validation path), and -blind 5xx retry. - -Known constraints, and how these decisions land on them: -- Rule G2 (originally specced in the now-retired `tasks/6.2-kubernetes-manifests.md`, - deleted 2026-08-25 since Phase 6 shipped and is live in-cluster) mandated **no - ServiceAccount/RBAC** on the gateway pod, and routes loaded from a git-sourced - ConfigMap with a pod roll on every change. The gateway pod now consumes the CRD - directly — no separate operator/controller pod. This is a deliberate, acknowledged - supersession of G2 for this one narrow purpose: the existing `api-gateway` - `ServiceAccount` (already bound to the pod at `k8s/rbac.yaml:1-7`, currently with - zero Role — see `k8s/rbac.yaml:9-10`'s own comment "the gateway has no k8s API - access") gains a namespace-scoped `Role` limited to read-only access on one CRD, - defined in this same repo and synced by the existing `api-gw` ArgoCD Application - (`homelab/k8s/argocd/apps/55-api-gateway.yaml`) — no new repo, no new Application. - Static ConfigMap-sourced routes keep the existing roll-on-change behavior; - CRD-sourced routes update live in-process instead (see §1). -- Retired `kmsvc.io` `TemporalWorker`/`Queue` CRD (`homelab/k8s/apps/messaging/queue-crd/`, - controller in the separate `kmsvc-manage` repo) broke via an uncleared finalizer and - RBAC rules that drifted out of sync with the CRD's resources - (`temporalworkers.kmsvc.io is forbidden ... at the cluster scope`). Cluster-scoped - RBAC, RBAC/CRD drift, and finalizer complexity are explicitly avoided this time — - this CRD is namespace-scoped (`api` only) and read-only from the gateway's side. - ---- - -## 0.

Service onboarding (new backend service = code change vs. YAML) - -### Existing System -- No CRD, no controller, no generic service registry anywhere in either repo. -- Adding a service today means: write a new Go handler, add a `switch` case, redeploy - the gateway image. Only `workflow` exists (`internal/temporal/handler.go`); `s3`, - `sqs`, `iam` don't exist in code at all. -- `internal/config/config.go` + `loader.go` load only static, hand-edited route config - from the ConfigMap already live per Phase 6 (`k8s/configmap.yaml`) — no per-service - schema, no CRD. - -### Future System -New CRD **`ServiceAdapter`** (`gateway.riotpiao.com/v1`, namespace-scoped to `api` -only — deliberately *not* cluster-scoped, unlike the retired CRD). Named for what it -actually does — adapts an in-cluster service to the gateway's -`X-Service`/`X-Resource` contract — rather than a generic "Definition". - -**No separate operator pod.** The API gateway pod itself consumes the CRD directly: it -runs a `client-go` informer against `ServiceAdapter` in namespace `api` and keeps an -in-memory route registry that adds/updates/removes entries as CRs change — no -ConfigMap render step, no restart-to-pick-up-changes, no second binary/Deployment/image -to build and operate. - -**Where the CRD is defined — this repo, not `homelab`.** Confirmed at -`homelab/k8s/argocd/apps/55-api-gateway.yaml:42-45`: the `api-gw` ArgoCD Application -already sources this repo's own `k8s` path directly (kustomize — Deployment, Service, -ConfigMap, RBAC, NetworkPolicy), auto-syncing on every push to `main`, wave 7. So the -CRD manifest is just another file in that same kustomization: new -`k8s/crd-serviceadapter.yaml`, added to `k8s/kustomization.yaml`'s `resources:` list. -When a new `ServiceAdapter` CR is introduced (i.e. someone commits a CR YAML for a new -service), ArgoCD syncs it through this same already-existing Application, and the -already-running `api-gw` pod's informer notices it and starts accepting -`X-Service: ` calls — no new Application, no new repo, no manual step in -`homelab` at all. Go API types back the CRD from -`apis/gateway/v1/serviceadapter_types.go` (new package, generates the CRD YAML via -`controller-gen`, same struct also used by the informer). - -`spec.auth.capability` is the default capability required for every resource on the -service. A method entry may override it with its own `auth.capability` — needed once -a service splits read vs. write access (see §6's `memory` adapter). No override means -inherit the spec-level default; `auth.required: false` at either level means no -capability check at all for that scope. - -**Example CR** (onboarding a hypothetical `postgres` service — no Go code, no image -rebuild, no manual gateway restart): - -```yaml -apiVersion: gateway.riotpiao.com/v1 -kind: ServiceAdapter -metadata: - name: postgres - namespace: api -spec: - serviceName: postgres # matches X-Service: postgres - upstream: - url: http://kmsvc-postgres-helper.sqs.svc.cluster.local:8080 - timeoutSeconds: 10 - auth: - required: true - capability: postgres:access # checked against the caller's JWT claims - retryable: true # eligible for the blind 5xx retry middleware, §4 - resources: - - name: query # X-Resource: query - methods: - - verb: POST - upstreamPath: /v1/query - requestSchema: - fields: - sql: string - params: array - required: ["sql"] - responseSchema: - fields: - rows: array - - name: table - methods: - - verb: GET - upstreamPath: /v1/tables/{id} # {id} filled from the trailing path segment - - verb: DELETE - upstreamPath: /v1/tables/{id} -status: - phase: Ready - observedGeneration: 1 -``` - -Calling it once reconciled — straight to the gateway root, no dedicated sub-path: - -```bash -curl -X POST https://api.riotpiao.com/ \ - -H 'Authorization: Bearer ' \ - -H 'X-Service: postgres' \ - -H 'X-Resource: query' \ - -d '{"sql": "select 1"}' -``` - -**RBAC** — extend `k8s/rbac.yaml` in place (same file that already defines the -`api-gateway` `ServiceAccount` at lines 1-6, currently role-less per its own "the -gateway has no k8s API access" comment). A namespace-scoped `Role` (not `ClusterRole`), -read-only, nothing else — this is the entire RBAC footprint added to the gateway pod, -shipped in the same repo/PR as the CRD itself: - -```yaml -apiVersion: rbac.authorization.k8s.io/v1 -kind: Role -metadata: - name: api-gateway-serviceadapter-reader - namespace: api -rules: - - apiGroups: ["gateway.riotpiao.com"] - resources: ["serviceadapters"] - verbs: ["get", "list", "watch"] ---- -apiVersion: rbac.authorization.k8s.io/v1 -kind: RoleBinding -metadata: - name: api-gateway-serviceadapter-reader - namespace: api -roleRef: - apiGroup: rbac.authorization.k8s.io - kind: Role - name: api-gateway-serviceadapter-reader -subjects: - - kind: ServiceAccount - name: api-gateway - namespace: api -``` - -No `status`/`finalizers` verbs, no write access at all — the gateway only ever reads. -No new `ServiceAccount`, no new Deployment, no new container image. - -**Gateway-side consumer** — new `internal/serviceadapter/registry.go`: a `client-go` -`SharedInformer` on `ServiceAdapter` in namespace `api`, feeding an in-memory map keyed -by `spec.serviceName` that the `internal/serviceadapter` dispatcher (§2) reads on every -request.

Deliberately a flat key→type map, author-facing (whoever writes the CR -specifies it, no JSON Schema knowledge needed): - -```yaml -requestSchema: - fields: - sql: string # one of: string | number | boolean | array | object - params: array - required: ["sql"] # optional; omit if every field is optional - strict: false # optional, default false — true rejects unlisted keys -responseSchema: - fields: - rows: array -``` - -One level deep only — `params: array` checks "is this an array," not what's -inside it. No enums, no formats, no nested field validation. Accepted limitation: -none of the adapters in this doc (postgres, workflow, iam, memory) need more than -top-level shape checking. - -**Extension forced by real upstream shapes (poimen-memory, §6):** the DSL above -only describes a top-level JSON *object*. `GET /memory/projects` returns a bare -array (`["poimen", ...]`), `GET /memory/query` returns an array of objects, and -`GET /memory/skills` returns objects with an explicit `"generated_from": null`. -Neither is expressible in the object-only form, so two additions, kept minimal -rather than backsliding toward full JSON Schema: - -```yaml -responseSchema: - type: array # top-level shape; default "object" if omitted - items: string # scalar array — every element must be this type -responseSchema: - type: array - items: - fields: # object array — one level deep INSIDE each item - level: string - sha256: string - score: number -responseSchema: - fields: - generated_from: { type: string, nullable: true } # long form only needed for nullable -``` - -Rule: a field written as a bare type string (`sql: string`) is shorthand for -`{type: string, nullable: false}`. `null` satisfies any field marked -`nullable: true` regardless of its declared type; a `null` on a non-nullable -field is a `type_mismatch`. Still one level deep — `items: { fields: {...} }` -does not itself accept a nested `items`. - -Validated in Go via `internal/serviceadapter/validate.go` (new, ~40 lines, no -external dependency): `json.Unmarshal` the body into `map[string]interface{}`, -check `Required` fields are present, check each present field in `Fields` against -its Go runtime type (`string`→string, `float64`→number, `bool`→boolean, -`[]interface{}`→array, `map[string]interface{}`→object), and if `strict: true` -reject any body key not listed in `Fields`. Compiled once per CR add/update in the -informer callback above, not per-request — the parsed `FieldSchema` struct is -stored directly in the same registry map entry as the route. - -Request-side violations are enforced: 400, RFC 9457 `problem+json`, body -`{type, title, detail, errors: [{field, reason}]}` where `reason` is one of -`missing`, `type_mismatch: want X got Y`, or `unknown_field` (strict mode only). -Response-side violations are **not** enforced — the response is forwarded to the -caller unchanged; a mismatch only emits a -`serviceadapter_response_schema_mismatch{service,resource}` metric and a log line. -Rationale: request validation is a trust boundary (external caller input); -response validation is contract-drift detection against our own upstream — turning -a backend field-shape typo into a caller-facing 502 does more harm than logging it. - ---- - -## 2. Request shape: body action vs. header verb - -### Existing System -- `internal/temporal/handler.go`: `POST /workflow` only, body is - `{action, namespace, payload}` (`RequestPayload` struct) — action dispatch happens - by reading and branching on the JSON body, not by header/method. -- `internal/server/router.go` dispatches purely by **path**: exact-matches - `/healthz`, `/readyz`, `/workflow`, `/workflow/health`, `/workflow/metrics`, and - falls through everything else (including `/v1/chat/completions`) to - `upstreamHandler`. There is no header-based dispatch anywhere in the router today. -- `s3`/`sqs`/`iam` bodies with `operation`/`action` fields, and a `/unified` sub-path, - were only ever prose in an earlier draft of this doc — never implemented, and now - dropped. - -### Future System -No new sub-path is introduced. `internal/server/router.go`'s `ServeHTTP` gets one new -branch, checked **before** the existing path switch: if the request carries an -`X-Service` header, dispatch straight to a new `internal/serviceadapter/router.go` -dispatcher, regardless of `r.URL.Path` (callers hit `https://api.riotpiao.com/` at the -root). `/v1/chat/completions`, `/v1/embeddings`, `/v1/rerank`, `/healthz`, `/readyz` -keep their existing path-based routing in `internal/proxy/router.go` — those never -carry `X-Service` and are matched first. `/workflow*` stays mounted during migration, -delegating internally to the same dispatcher, then gets removed once callers move to -header-based calls. - -Dispatch key becomes **`X-Service` header → adapter**, then **HTTP method + -`X-Resource` header → `{verb, upstreamPath}`** — e.g. `GET` to the gateway root + -`X-Service: iam` + `X-Resource: user` → list Authentik users. This replaces the body -`action`/`operation` field convention everywhere, not just for `iam` — so the -rewritten `workflow` adapter looks like: -- `POST X-Resource: workflow` → `START_WORKFLOW` -- `GET X-Resource: workflow/{id}` → `QUERY_WORKFLOW` -- `GET X-Resource: workflow` → `LIST_WORKFLOWS` -- `DELETE X-Resource: workflow/{id}` → `TERMINATE_WORKFLOW` -- `GET X-Resource: workflow/{id}/history` → `GET_WORKFLOW_HISTORY` -- Same pattern for new `s3` (`bucket/{key}`) and `sqs` (`queue/{name}/message`) - adapters — built fresh, since they don't exist in code today. - -`/v1/chat/completions`, `/v1/embeddings`, `/v1/rerank` in `internal/proxy/router.go` -are **unchanged** — local-LLM-only, no `X-Service` involvement. - ---- - -## 3. IAM access to Authentik - -### Existing System -- No `X-Service: iam` adapter in the gateway. -- Authentik admin API access exists today only client-side, in the Rust `core` CLI - (`/Users/rockliang/workplace/core/src/cmd/iam/*.rs`), which already calls - `{authentik_url}/api/v3/core/applications/`, `/api/v3/providers/oauth2/`, - `/api/v3/core/flows/`, `/api/v3/crypto/certificatekeypairs/` for apps/providers/flows - — confirmed at `core/src/cmd/iam/app.rs:136,160,191,205,219`. No users/groups/roles - coverage there, and none of it is reachable through the gateway. - -### Future System -New `internal/iam/handler.go` server-side adapter, reachable at the gateway root with -`X-Service: iam`, mapping `X-Resource` + method onto Authentik's `/api/v3/...` surface: - -| X-Resource | Method | Authentik endpoint | -|---|---|---| -| `user` | GET/POST | `/api/v3/core/users/` | -| `user/{id}` | GET/PATCH/DELETE | `/api/v3/core/users/{id}/` | -| `service-account` | POST | `/api/v3/core/users/service_account/` | -| `role` (group) | GET/POST | `/api/v3/core/groups/` | -| `permission` | GET/POST | `/api/v3/rbac/permissions/` | -| `flow` | GET | `/api/v3/flows/instances/` | - -This is additive to, not a replacement of, the `core iam` CLI subcommand — different -caller (server vs. local CLI), same upstream API. - ---- - -## 4. Auth: how a caller proves identity - -### Existing System -- `internal/auth/` is an **empty directory** — zero implementation. `tasks/` Phase 3 - (JWKS fetch/rotation, Bearer validation, Authentik service account, flag-gated - rollout, capability authorization) was retired 2026-08-25 — this doc is now the spec - for that work instead of those deleted task files. -- `kmsvc.riotpiao.com` (separate service) has an auth interceptor - (`kmsvc-manage/internal/api/interceptors/auth.go`, JWKS validation via - `lestrrat-go/jwx/v2/jwt`) but it's **never wired in** — `cmd/server/main.go` builds a - bare `grpc.NewServer()` (`kmsvc-manage/cmd/server/main.go:84`), and the REST surface - bypasses gRPC interceptors entirely even once fixed. Useful code to reference, not to - copy the deployment of. -- The `core` CLI already does human OIDC login (`core auth login` — device-code/OOB - against Authentik) and caches a token at `~/.cache/talos/authentik_id_token` - (`core/src/cmd/auth/mod.rs:336-338`) — a **different** token/cache than what §5 adds. - -### Future System -Implement in `internal/auth`, with two entry paths converging on one validated-JWT -middleware — no separate downstream logic per path: -1. **Bearer passthrough** — `Authorization: Bearer ` sourced from - `~/.talos/.riotpiao-auth` (written by `mwinit`, §5), validated against Authentik's - JWKS. -2. **Service-account password grant** — Authentik service-account username/password - exchanged for a JWT. Reuse the validation *logic* already written (but unwired) in - `kmsvc-manage/internal/api/interceptors/auth.go`, not its deployment config. - -Retry middleware (`internal/resilience/retry.go`, new) wraps every outbound upstream -call from the `internal/serviceadapter` dispatcher: **blind retry on any 5xx**, bounded -attempts with backoff, no idempotency-key gating — Temporal (and other backends) own -dedup on their side. `ServiceAdapter.spec.retryable` (default `true`) is the only -opt-out. - ---- - -## 5. `CLI-MWNINIT.md` (separate doc) - -### Existing System -The Rust `core` CLI (`/Users/rockliang/workplace/core`) has `core auth login` -(`src/cmd/auth/mod.rs`) for human OIDC device-code/OOB login, and a separate `core iam` -subcommand tree (`src/cmd/iam/`) for app/group/scope management. There is no -service-account login path and no `~/.talos/` token file — the existing cache is -`~/.cache/talos/authentik_id_token`, and `~/.talos` today only holds Talos *node* -config (`TALOSCONFIG`, per `core/src/config.rs:25-26`), unrelated to Authentik JWTs. - -### Future System -New `core mwinit` subcommand (new `src/cmd/mwinit/mod.rs`, same structure as -`src/cmd/auth/mod.rs` — not a new binary), documented in a separate `CLI-MWNINIT.md`: -- **Purpose** — authenticate as a dedicated Authentik service account (not a human - device-code login) and cache the resulting JWT for use against `api.riotpiao.com`. -- **Two paths**: `core mwinit login --username --password <...>` - (Authentik service-account grant, same `AUTHENTIK_URL` default as `core auth login`, - `core/src/cmd/auth/config.rs:18`), or `core mwinit login --token ` to - just re-cache an already-issued token. -- **Storage**: `~/.talos/.riotpiao-auth` — a new, separate path from `core auth - login`'s `~/.cache/talos/authentik_id_token`, so the two tools never collide. -- **Usage**: `curl -H "Authorization: Bearer $(cat ~/.talos/.riotpiao-auth)" -H 'X-Service: ...' https://api.riotpiao.com/ ...`. -- **Lifecycle**: `core mwinit status` / `core mwinit clear` (mirroring `core auth - status`/`clear`); gateway behavior on expired token is 401 + `WWW-Authenticate`, - RFC 9457 problem+json. - ---- - -## 6. `X-Service: memory` — poimen-memory - -### Existing System -`poimen-memory` (`~/workplace/Poimen/memory`) is real and **already deployed** — -namespace `poimen`, Service `poimen-memory.poimen.svc.cluster.local:8080`, 2 pods -`Running`.

Perfect for homelab scale - -**Setup:** -1. Configure Authentik OIDC provider -2. Enable "Use claims-based access tokens" option -3. Add groups to token claims -4. Developers get JWT instead of random string -5. Git hook validates JWT locally (no API call) - -**Code example for git hook:** -```bash -#!/bin/bash -# .git/hooks/update (server-side) - -token=$(git log -1 --pretty=%B | grep "X-SOPS-Token" | cut -d' ' -f2) - -# Verify JWT signature -jwt verify $token --key /path/to/authentik/public.key - -# Decode and check groups -groups=$(jwt decode $token | jq .groups) -if [[ !

The gateway doesn't validate or enforce tool support. - -**Q: Can I mix OpenAI and Anthropic tool formats?** -A: Not in the same request. OpenAI clients expect `tool_calls`, Anthropic clients expect `tool_use` blocks. The upstream API determines the format. - -**Q: How are tool arguments limited?** -A: By the per-route `maxBodySize` config.

Runtime and configuration - -### 1.1 Process - -Single static Go binary. Reads configuration at startup, serves HTTP, exits cleanly -on SIGTERM after draining in-flight requests. - -Must run with **no cluster, no kubeconfig and no credentials** so that behaviour can -be verified in a closed loop before touching live traffic. Upstreams are -configuration; pointing them at local stubs is the entire mechanism. This is a hard -requirement, not a convenience — see §7. - -### 1.2 Configuration - -Route and upstream configuration is declarative and loaded at startup. It must -express, per upstream: address, path rewrite, connect/read/write timeouts, maximum -body size, and whether the route requires authentication. - -Configuration errors fail startup loudly. A gateway that starts with a silently -dropped route is worse than one that refuses to start. - -**Configuration lives in git**, mounted as a ConfigMap and synced by Argo. Not a -CRD. A CRD would require the gateway to watch the API server, which needs RBAC and -contradicts G2 — and CRD-driven routing is precisely the indirection being retired -with Kong, where the routing table was split across six `KongPlugin` CRs, seven -Ingresses and a Helm values file. - -A CRD earns its keep when someone other than the repo owner must register routes. -That is not true here. If it becomes true, the additive answer is a controller that -renders this same ConfigMap — the gateway stays credential-free either way. - -### 1.3 Health - -- `GET /healthz` — liveness, no upstream checks, always cheap. -- `GET /readyz` — readiness; may fail while configuration is invalid or JWKS has - never been successfully fetched. - -Neither requires authentication. - ---- - -## 2. Proxy core - -### 2.1 Reverse proxying - -Standard reverse proxy to configured upstreams. Connection reuse across requests. -Hop-by-hop headers stripped correctly. `X-Forwarded-*` set from the nginx-supplied -values, not fabricated. - -### 2.2 Streaming - -SSE and chunked responses pass through without buffering. Tokens must reach the -client as the upstream emits them, not on completion. - -WebSocket upgrade must work — `agent-pod/console` depends on it. - -### 2.3 Disconnect propagation - -When a client disconnects, the upstream request is cancelled immediately. This is -load-bearing: an orphaned generation holds a vLLM sequence slot, and there are only -eight in the cluster. - -### 2.4 Timeouts - -Per-route, explicit. Current Kong values, which are deliberate and must be preserved -unless changed knowingly: - -| Route class | connect | read | write | -|---|---|---|---| -| chat | 10s | 1h | 1h | -| embeddings, rerank | 10s | 10m | 10m | - -The 1-hour read timeout exists because a 32B model on a Volta GPU routinely exceeds -60s. Any shorter application-level cap must be enforced *by the gateway's own -logic*, not by shortening the proxy timeout — otherwise long legitimate generations -truncate mid-stream. - ---- - -## 3. LLM surfaces — `api.riotpiao.com` - -Two protocol dialects, permanently. Both translate into one dialect-neutral canonical -request, and both pass through **one shared slot controller** before reaching a -predictor. - -| Prefix | Dialect | Primary client | -|---|---|---| -| `/v1/*` | OpenAI-compatible | pi, generic OpenAI SDKs | -| `/llm/*` | Anthropic Messages | the riotpiao frontend (first-party only) | - -``` - /v1/* (OpenAI) /llm/* (Anthropic) - | | - +-----------+------------+ - v - canonical request dialect-neutral - v - slot controller keyed by UPSTREAM, not by route - v - reasoning-predictor / ornith-predictor -``` - -**The slot controller is keyed by upstream and shared across dialects.** Per-dialect -semaphores are wrong: the 8 sequence slots are physical, so two independent gates -would each believe they were within budget while together exceeding it. Requests from -both surfaces contend for the same slots and the same queue, in arrival order. - -Dispatch, budgets, logging and metrics all operate on the canonical request. Adding a -third dialect later must not require touching the controller. - -### 3.1 Body-based model dispatch - -`POST /v1/chat/completions` selects its upstream from the request body's `model` -field. This is the single most important requirement in this document: it is the -capability Kong OSS lacked, and the reason the gateway exists. - -Unknown or missing `model` is a client error with a useful message listing valid -values — not a 500, and not a silent fallback to a default model. - -### 3.2 Upstream map - -Verified live. `served-model-name` values are what clients send. - -| `model` in body | Upstream Service | Engine | -|---|---|---| -| `reasoning` | `reasoning-predictor.llm-serving:80` | vLLM, DeepSeek-R1-Distill-Qwen-32B | -| `ornith:35b` | `ornith-predictor.llm-serving:80` | Ollama | -| `qwen2.5:3b-instruct` | `ornith-predictor.llm-serving:80` | Ollama, same pods | -| `nomic-ai/nomic-embed-text-v2-moe` | `embeddings-predictor.llm-serving:80` | TEI | -| `BAAI/bge-reranker-base` | `reranker-predictor.llm-serving:80` | TEI | - -`reasoning` runs 2 replicas × `--max-num-seqs=4` = **8 concurrent sequence slots -total**, `--max-model-len=16384`, `--reasoning-parser=deepseek_r1`, -`--enable-auto-tool-choice --tool-call-parser=hermes`. - -Note `ornith:35b` and `qwen2.5:3b-instruct` share pods; both stay resident via -`OLLAMA_MAX_LOADED_MODELS=2` and `OLLAMA_KEEP_ALIVE=-1`, so dispatching between them -does not trigger a model swap. - -### 3.3 Path rewriting - -Upstreams expect canonical paths. `/v1/chat/completions` and `/v1/embeddings` pass -through unchanged. Rerank is the exception: TEI serves `/rerank`, not `/v1/rerank`, -so that route rewrites. - -### 3.4 Legacy path aliases - -`/v1/{reasoning,ornith,qwen}/chat/completions` must keep working during cutover — -pi is a live caller. They behave exactly as the canonical endpoint with `model` -forced to the corresponding value, overriding whatever the body says. - -These are temporary. They exist to make the cutover reversible, and are removed once -callers have migrated. - -### 3.5 `GET /v1/models` - -Derived from the configured upstream map, never hardcoded. Kong served a static -list, and its own manifest flags that the list can drift from what the engines -actually serve. The gateway's list must be incapable of disagreeing with what -routing will accept. - -OpenAI list shape: `{"object":"list","data":[{"id","object":"model","owned_by","created"}]}`. - -### 3.6 Behaviour to preserve - -Verified against the live endpoint: - -- The upstream returns `reasoning_content` separately from `content` for the - `reasoning` model. Pass both through untouched. -- Tool calling works with explicit `tool_choice`, and is unreliable with - `tool_choice: auto` on the R1-distill model. The gateway does not compensate for - this — it is a model property, not a gateway concern. Do not add retries or - rewriting to work around it. - ---- - -## 4. Authentication — Authentik - -### 4.1 Current state - -**The model API is unauthenticated today.** Confirmed live: `/v1/reasoning/chat/completions` -answers with no credentials. - -Kong's `key-auth` was retired because it accepts a raw `apikey:` header but rejects -`Authorization: Bearer`, which hard-blocks every OpenAI-compatible client. See -`~/workplace/homelab/k8s/apps/api/model-auth.yaml`. - -### 4.2 Requirement - -Bearer tokens in `Authorization`, validated against Authentik -(`https://authentik.riotpiao.com`) by fetching and caching JWKS at runtime. - -Key rotation must be handled by refetching JWKS, not by pinned PEMs. The -pinned-`rsa_public_key` approach in `AUTH-PLAN.md` and its rotation runbook exist -only to route around a Kong OSS limitation and must not be carried forward. - -Service accounts obtain tokens via `client_credentials` against Authentik's token -endpoint. - -### 4.3 Rollout - -Auth ships behind a flag, defaulting off, and is enabled deliberately. - -Enabling it breaks every current caller until they hold a token — pi included, whose -`models.json` currently sends a `customHeaders: {apikey: ...}` block that will need -replacing with a Bearer token. - -### 4.4 Authorization - -Beyond authentication, a token must be checked for the right to invoke the -capability it is calling. A token minted for queue access should not invoke a GPU. - ---- - -## 5. Rate limiting and budgets - -No `rate-limiting` plugin exists anywhere in the cluster today — this is net new -work, not a migration. Verified: six Kong plugins exist, none is `rate-limiting`. - -Requirements, in priority order: - -1. **GPU slot protection.** `reasoning` has 8 total sequence slots. Concurrent - in-flight requests to it must be capped below that, leaving operator headroom. - Excess requests queue up to a bounded depth, then are rejected with a retryable - status. -2. **Per-caller budgets.** Identified callers get a request budget over a window. -3. **Body size caps**, per route. - -Rejections use RFC 9457 `application/problem+json` and set `Retry-After` where a -retry time is knowable. - ---- - -## 6. Observability - -Kong's cluster-wide `prometheus` plugin is being retired. The gateway must expose at -least equivalent signal or observability regresses at cutover: request rate, -latency, status codes, bandwidth, and upstream health, labelled by route and -upstream. - -Gateway-specific signals that Kong could not provide, and which are the reason for -several requirements above: in-flight requests per upstream, queue depth, GPU slot -occupancy, and rejections by reason. - -Structured logging. Every rejected request is logged with the reason. No secrets, no -tokens, no request bodies in logs. - ---- - -## 7. Local development and verification - -An agent must be able to close a change/verify loop with no cluster, no kubeconfig -and no credentials. This is a hard requirement because it determines whether work can -proceed unattended. - -Concretely: it must be possible to start the gateway locally, point it at stub -upstreams, issue requests, and assert on the responses — including streaming -responses and client disconnects. - -Verification of any API-shaped task means asserting on the **actual HTTP response**: -status, headers, and body. "It compiles" and "it starts" are not verification. - -Parity with Kong is verified by comparing gateway and Kong responses for the same -request, for every route in the migration inventory, before cutover. - ---- - -## 8. Deployment - -Container: distroless or scratch, `runAsNonRoot`, read-only root filesystem, all -capabilities dropped, `seccompProfile: RuntimeDefault`, no shell. - -Image tags are commit SHAs, never `:latest` — Argo's `selfHeal` cannot roll out a -mutable tag reliably. - -NetworkPolicy: egress only to the upstreams it proxies plus Authentik; ingress from -`ingress-nginx` only. - -Deployed as an Argo Application in the `homelab-root` GitOps repo. Verified live: -zero Argo Applications anywhere in the cluster source from any Forgejo URL, so -`github.com/Riotpiaole/riotpiao.homelab.com` is authoritative. - ---- - -## 9. Capability surface — path-based - -Every capability is a path prefix on the single host `api.riotpiao.com`. One DNS -record, one Cloudflare tunnel hostname, one nginx Ingress, one Service. - -| Prefix | Backs onto | Status | -|---|---|---| -| `/v1/*` | `llm-serving` predictors | v1 — **reserved**, see below | -| `/sqs/*` | kmsvc management-service, Kafka/Strimzi (`sqs` ns) | future | -| `/workflow/*` | Temporal (`temporal` ns) | future | -| `/cluster/*` | atlas, separate repo `riotpiao-backend` | future | -| `/db/*` | CloudNativePG, MinIO, monitoring reads | future | - -**`/v1/*` is reserved for the OpenAI-compatible surface and nothing else.** G3 pins -it: an SDK expects `/v1/chat/completions` at the base URL, so that prefix can never -be repurposed or nested. Every other capability gets its own prefix that cannot -collide with a current or future OpenAI path. - -Subdomains are deliberately *not* used. Paths keep hostname configuration to a -single entry — and hostname configuration is the demonstrated failure mode here, as -the unresolved apex 403 shows. Promoting a prefix to its own subdomain later is an -additive host rule that can run alongside the path; the reverse is not, because -clients hardcode hostnames. - -Notes carried from the cluster: - -- Temporal namespace registration is automatic via queue-operator, never manual. -- `management-service` already exposes gRPC at `kmsvc.riotpiao.com`; the `/sqs` - prefix is a new surface, not a replacement for it. -- atlas keeps its own informers and RBAC. The gateway proxies to it and holds no - cluster credentials of its own (G2). -- `/db/*` read surfaces need particular care — see G2 before designing them. - ---- - -## 10. Known cluster facts worth not rediscovering - -- `kmsvc-redis-master.sqs:6379` has **no authentication** — `ALLOW_EMPTY_PASSWORD=yes`, - TLS off. Any workload with network reach has full unauthenticated read/write. A - NetworkPolicy is the only control. -- `reasoning-predictor` listens on port **80**, not 8080. -- `prometheus-operated.monitoring` is **headless** (ClusterIP None) — egress policies - need pod selectors, not ClusterIPs. -- `agent-pod/console` is publicly routed, unauthenticated, accepts free-form prompts - into a shell-capable container, and serves a WebSocket. Putting it behind gateway - auth is a security fix, not merely a port. -- Eight `*.example.com` hosts exist on istio-class Ingresses in `llm-serving`. KServe - defaults, not public, out of scope — do not mistake them for gateway routes. diff --git a/TEMPORAL_GRPC_MIGRATION.md b/TEMPORAL_GRPC_MIGRATION.md deleted file mode 100644 index b6c38ce..0000000 --- a/TEMPORAL_GRPC_MIGRATION.md +++ /dev/null @@ -1,176 +0,0 @@ -# Temporal gRPC Integration - Migration Status - -## Overview - -Temporal REST ↔ gRPC bridge is being implemented.

Workers create/manage queues automatically -❌ **Complex State** - Queue state changes automatically with worker connections - ---- - -### Option 2: Hidden Implementation Detail (NOT RECOMMENDED) - -**Design**: Don't expose TaskQueue operations; let workers manage queues - -**Pros**: -✅ **Simpler API** - Fewer operations -✅ **Fewer Bugs** - Less user confusion -✅ **Less Operational Burden** - Workers handle it - -**Cons**: -❌ **No Visibility** - Can't see queue status -❌ **Harder Debugging** -

Widening scope is a code change with a test, not an accident. - ---- - -## Shared behaviour, both dialects - -**One slot controller, keyed by upstream.** A `/v1` request and a `/llm` request contend for the same 8 `reasoning` slots and the same queue, in arrival order. Per-dialect semaphores would each believe they were within budget while together exceeding the physical limit. - -**Streaming is unbuffered** and a client disconnect cancels the upstream immediately. An orphaned generation holds a slot until it completes on its own, which for a 32B model on a Volta GPU can run to minutes. - -**Timeouts** [LIVE]: chat routes are connect 10s / read 1h / write 1h. The hour is deliberate — a 32B model on this hardware routinely exceeds 60s. Any shorter application cap is enforced in gateway logic, never by shortening the proxy timeout. - -**Tool calling** [LIVE]: `reasoning` honours an explicit `tool_choice` but returns `tool_calls: []` under `tool_choice: "auto"` — it reasons about the tool in prose instead. `ornith:35b` returns `finish_reason: "tool_calls"` correctly under `auto`.

OIDC is Enterprise-only.** -`k8s/apps/api/AUTH-PLAN.md` routes around the missing `openid-connect` plugin using the -built-in `jwt` plugin, which requires pinning Authentik's RSA public key onto a -KongConsumer. That plan lists its own consequence: - -> Pinning `rsa_public_key`: Authentik key rotation would break it — document a rotation -> runbook, or have the provision script re-export the cert PEM into the Kong credential on -> each run. - -A rotation runbook is a standing operational liability accepted only because the gateway -cannot fetch JWKS itself. - -**3. `key-auth` cannot read `Authorization: Bearer`.** -From `k8s/apps/api/model-auth.yaml`: - -> a raw `apikey: ` header succeeds (200), the same request with only -> `Authorization: Bearer ` fails (401).

But the path-per-model surface stays -non-standard, the RSA pinning runbook stays, and auth stays off until someone writes a -`request-transformer` shim to copy Bearer into an `apikey` header. Every new capability -(`sqs`, `workflow`) inherits the same constraints. - -**B. Buy Kong Enterprise.** -`ai-proxy-advanced` and `openid-connect` solve 1 and 2. Does not solve the genuinely -application-level requirements at all — signed session cookies, per-session daily message -budgets, a 6-of-8 GPU sequence-slot semaphore with a bounded queue, and -disconnect-cancels-upstream are not gateway features in any tier. Cost for a homelab is not -justifiable. - -**C. Go gateway, Kong retained for LLM paths only.** -Gradual migration, lower risk. But it means running two gateways indefinitely, splitting the -routing table across Kong CRDs and Go code, and keeping the Kong Helm release and its CRDs. -The split is the thing most likely to drift. - -**D. Go gateway, Kong retired entirely.** — chosen -One routing table, one auth implementation, one place to reason about timeouts. The logic -being replaced is small: four `request-transformer` plugins that set a body field and -rewrite a URI, one `request-termination` serving a static JSON model list, and one -`prometheus` plugin. That is on the order of a hundred lines of Go, against roughly 480 -lines of YAML it retires. - -## Consequences - -### Gained - -- **Standard OpenAI surface.** One `POST /v1/chat/completions`, model selected from the - request body.
