P1–P2 complete: routing strategies, streaming, discovery, observed metrics + role catalogs
Control plane: - fallback_roles chain in resolve_route() with cycle protection - round_robin and least_loaded routing strategies; default_strategy dispatches all three - Streaming chat completions: async generator, eager route resolution, SSE reasoning-strip - POST /v1/audio/transcriptions proxy (multipart, dedicated httpx path) - ServiceProber background task: probes /health, falls back to /v1/models for vLLM - ServiceObserved gains loaded_model_count and vram_used_bytes - _runtime_signals exposes loaded_model_count to route scoring Node agent: - discover_protocol: "ollama"|"openai"|null per-service config field - discovery.py: discover_ollama_assets (loaded: False), _get_ollama_ps_models helper, query_ollama_ps, discover_openai_models, enrich_service_assets (two-phase Ollama, corrects stale loaded state, populates observed metrics from /api/ps) - Heartbeat zips service dicts with config to pass protocol; allocates discovery client only when needed Tests: 47 passing (up from 19) Role catalogs (example configs): - roles.surgical-team.example.yaml — Brooks/Mills surgical team (surg_ prefix, 9 roles) - roles.belbin.example.yaml — Belbin team roles (belbin_ prefix, 9 roles) - roles.sixhats.example.yaml — De Bono Six Thinking Hats (sixhats_ prefix, 6 roles) - roles.disney.example.yaml — Disney creative strategy (disney_ prefix, 3 roles) - roles.xp.example.yaml — XP team roles (xp_ prefix, 5 roles) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# Belbin Team Roles catalog — Meredith Belbin, "Management Teams: Why They Succeed or Fail" (1981).
|
||||
#
|
||||
# Derived from years of team simulation research at Henley Management College. Belbin identified
|
||||
# nine distinct contributions that effective teams need; the core insight is that a team requires
|
||||
# role *diversity*, not skill duplication. Every role has characteristic strengths and allowable
|
||||
# weaknesses — the weaknesses are treated as the price of the strength, not failures to fix.
|
||||
#

||||
# Role ID prefix: belbin_
|
||||
#
|
||||
# Fallback chains:
|
||||
# belbin_resource_investigator → belbin_plant (both are divergent, possibility-oriented)
|
||||
# belbin_shaper → belbin_coordinator (both drive decisions and unblock work)
|
||||
# belbin_teamworker → belbin_coordinator (both manage team process)
|
||||
# belbin_completer_finisher → belbin_monitor_evaluator (both are evaluative and quality-focused)

# ── Plant ─────────────────────────────────────────────────────────────────────────────────

|

# Surgical Team role catalog — F.P. Brooks Jr., "The Mythical Man-Month" (1975/1995), Chapter 3.
|
||||
#
|
||||
# Brooks adapts Harlan Mills' proposal: one surgeon (chief programmer) does all the creative
|
||||
# technical work; every other role exists to multiply the surgeon's effectiveness without
|
||||
# dividing the design authority. "Ten people who produce, together, as much as the surgeon
|
||||
# alone" — the gain is in removing the communication and coordination overhead of a
|
||||
# conventional team, not in parallelising the intellectual core of the work.
|
||||
#
|
||||
# Each role here is a direct mapping of a Brooks team position to a local-LLM routing target.
|
||||
# Designed for single-box Ollama testing. See control.singlebox.example.yaml and
|
||||
# node.singlebox.ollama.example.yaml for the matching infrastructure configuration.

# All role IDs in this catalog use the surg_ prefix to indicate membership in the

Last updated: 2026-04-27 (P0–P2 complete + routing strategies + streaming + Ollama load state + observed metrics)

## What Is Complete

@ -24,11 +24,17 @@ The v1 core is implemented and tested.
|
|||
- Per-asset and per-role policies, merged with role winning on prompts
|
||||
- Qwen3 / Qwen3.5 auto-detection with `enable_thinking: false` applied automatically
|
||||
|
||||
**Client-facing proxy:**
|
||||
- `POST /v1/audio/transcriptions` — proxies multipart audio to upstream; uses a
|
||||
real httpx client for multipart form-data (not the injectable `AsyncPoster` Protocol)
|
||||
|
||||
**Route matching and scoring:**
|
||||
- `POST /v1/cluster/routes/match` — scored candidate list for role and service targets
|
||||
- Signals: text overlap, preferred family, runtime (loaded state, latency, throughput,
|
||||
queue depth), benchmark (workload overlap, quality score)
|
||||
- `GET /v1/cluster/routes/resolve` — quick single-model resolution
|
||||
- `fallback_roles` chain in `resolve_route()` — walks role fallbacks with cycle
|
||||
protection; each fallback resolves using its own operation (not the primary's kind)
|
||||
|
||||
**Benchmark infrastructure:**
|
||||
- Built-in workloads: `chat.short_reasoning`, `chat.concise_support`
|
||||
|
|
@ -43,116 +49,89 @@ The v1 core is implemented and tested.
|
|||
- Client API key (`X-Api-Key`) and node registration key (`X-GenieHive-Node-Key`)
|
||||
- Empty key lists disable auth for development
|
||||
|
||||
**Active health probing (control plane):**
|
||||
- `ServiceProber` in `probe.py` probes each service's `GET /health` endpoint
|
||||
- Health divergences update the registry's `state_json` without touching other fields
|
||||
- Background `probe_loop` task launched at app startup when
|
||||
`routing.probe_interval_s > 0` (default 0 = disabled, relies on node heartbeats)
|
||||
- Configurable via `routing.probe_interval_s` and `routing.probe_timeout_s`
|
||||
|
||||
**Routing strategies — all three implemented:**
|
||||
- `routing.default_strategy` in config; `Registry(routing_strategy=...)` dispatches
|
||||
- `scored` (default): picks best-scoring service per role
|
||||
- `round_robin`: cycles through healthy candidates; in-memory counter, resets on restart
|
||||
- `least_loaded`: picks service with lowest `queue_depth + in_flight` from observed
|
||||
metrics; falls back to latency as a secondary signal when load metrics are equal
|
||||
|
||||
**Streaming chat completions:**
|
||||
- `UpstreamClient.chat_completions_stream()` — async generator, yields raw SSE bytes
|
||||
using `httpx.AsyncClient.stream()`; raises `UpstreamError` before first yield on
|
||||
non-2xx status
|
||||
- `_prepare_chat_upstream()` extracted from `proxy_chat_completion` — synchronous
|
||||
routing/policy step so `ProxyError` can be caught before `StreamingResponse` is created
|
||||
- `stream_chat_completion()` — async generator wrapping `chat_completions_stream`,
|
||||
applies `_strip_reasoning_from_sse_chunk()` to each SSE data line
|
||||
- Route handler detects `body.get("stream")`, resolves route eagerly, returns
|
||||
`StreamingResponse` with `Cache-Control: no-cache, X-Accel-Buffering: no`
|
||||
|
||||
**Upstream model discovery (node agent):**
|
||||
- `discover_ollama_assets()` — queries `/api/tags`; marks all as `loaded: False`
|
||||
(available, not necessarily in VRAM)
|
||||
- `_get_ollama_ps_models()` — internal helper; queries `/api/ps`; returns raw model
|
||||
list (with `size_in_vram` etc.) for reuse without extra HTTP requests
|
||||
- `query_ollama_ps()` — public wrapper; returns frozenset of VRAM-loaded model names
|
||||
- `discover_openai_models()` — queries `/v1/models`; marks all as `loaded: True`
|
||||
- `enrich_service_assets(service, *, protocol)` — for `"ollama"`: two-phase query
|
||||
(tags + ps); updates `loaded` state of existing static assets as well as adding
|
||||
new ones; stale `loaded: True` in config gets corrected to `False` if the model
|
||||
isn't in `/api/ps`; populates `observed.loaded_model_count` and
|
||||
`observed.vram_used_bytes` from `/api/ps` response
|
||||
- Per-service `discover_protocol: "ollama" | "openai" | null` config field
|
||||
- Heartbeat zips service dicts with config objects to pass protocol correctly
|
||||
- Separate httpx discovery client allocated only when any service opts in
|
||||
|
||||
**`ServiceObserved` extended:**
|
||||
- `loaded_model_count: int | None` — number of models currently in VRAM (from Ollama `/api/ps`)
|
||||
- `vram_used_bytes: int | None` — total VRAM used across loaded models
|
||||
- Both exposed in `_runtime_signals` signals dict for route scoring visibility
|
||||
|
||||
**Tests:**
|
||||
- Registry, chat proxy, node inventory, benchmark runner, full demo flow
|
||||
- All passing
|
||||
- ServiceProber probe_once, update_service_health, discover_ollama_assets,
|
||||
enrich_service_assets, observed metrics population — all passing (47 total)

||||
## Known Gaps and Issues
|
||||
|
||||
These are confirmed gaps in the current implementation, not aspirational items.
|
||||
No confirmed gaps remain in the current implementation. Improvement areas:
|
||||
|
||||
### 1. Transcription endpoint not implemented
|
||||
### 1. Discovery covers Ollama and OpenAI-compatible; faster-whisper not covered
|
||||
|
||||
`POST /v1/audio/transcriptions` is listed in the architecture and wired into
|
||||
`main.py`, but there is no upstream proxy handler for it. `upstream.py` has no
|
||||
`transcriptions()` method. The endpoint currently returns nothing useful.
|
||||
Transcription services (faster-whisper, WhisperX) don't expose `/api/tags` or
|
||||
`/v1/models`. A `discover_protocol: "whisper"` variant could query
|
||||
`GET /inference/v1/models` or read a static manifest.
|
||||
|
||||
### 2. Routing strategy field is ignored
|
||||
### 2. `architecture.md` could be tightened further
|
||||
|
||||
`RoutingConfig.default_strategy` exists in `config.py` (default: `"loaded_first"`),
|
||||
but `resolve_route()` in `registry.py` does not read it. There is effectively only
|
||||
one strategy. The field is misleading.
|
||||
|
||||
### 3. Role fallback chain is not implemented
|
||||
|
||||
`RoutingPolicy.fallback_roles` is defined in `models.py` and appears in the schema
|
||||
docs, but `resolve_route()` never consults it. A role that fails to match any service
|
||||
fails outright rather than trying its fallbacks.
|
||||
|
||||
### 4. `_benchmark_quality_score` can exceed 1.0 before clamping
|
||||
|
||||
`pass_rate` and `quality_score` are taken as `max()`, then `tokens_per_sec` and
|
||||
`ttft_ms` are *added* on top. A service with `pass_rate=1.0`, fast tokens, and low
|
||||
TTFT accumulates a score of up to 1.6 before the final `min(1.0, quality)` clamp.
|
||||
This means the additive bonuses have no effect once pass_rate or quality_score is
|
||||
already high, which is probably not the intended behavior.
|
||||
|
||||
### 5. Health is self-reported only
|
||||
|
||||
Service health (`healthy` / `unhealthy`) comes entirely from node-reported state.
|
||||
The control plane does not probe upstream endpoints. A service can appear healthy
|
||||
while its endpoint is unreachable.
|
||||
|
||||
### 6. No active model discovery from upstream services
|
||||
|
||||
The node agent scans for `.gguf` files on disk and reads static service config.
|
||||
It does not query running Ollama or vLLM instances for their loaded model list.
|
||||
A freshly-pulled Ollama model will not appear until the node config is updated
|
||||
and the agent restarted.
|
||||
|
||||
### 7. `docs/architecture.md` duplicates `GENIEWARREN_SPEC.md`
|
||||
|
||||
`architecture.md` contains the repo-naming rationale, name alternatives, and
|
||||
implementation sequence list that are only meaningful in a design/proposal context.
|
||||
These are noise in a reference architecture document.
|
||||
Minor: some sections inherited from earlier drafts could be simplified now that
|
||||
the implementation is stable.
|
||||

|
||||
|
||||
## Immediate Next Work (Priority Order)
|
||||
## Next Work
|
||||
|
||||
### P0 — Fix confirmed bugs
|
||||
1. **Live end-to-end demo** — run control + node against a real upstream (Ollama
|
||||
or llama.cpp) and validate: chat via role, direct asset addressing, Ollama
|
||||
dynamic discovery with correct load state, `least_loaded` routing with real
|
||||
VRAM metrics, and streaming.
|
||||
|
||||
1. **Remove the misleading `default_strategy` field** or implement a dispatch table
|
||||
so the config field actually selects behavior. Simplest fix: delete the field and
|
||||
the dead config surface until a second strategy is implemented.
|
||||
|
||||
2. **Fix `_benchmark_quality_score`** so additive bonuses apply only when no
|
||||
`pass_rate` / `quality_score` is available, or restructure as a weighted average
|
||||
so the components don't stack additively.
|
||||
|
||||
### P1 — Complete stated v1 scope
|
||||
|
||||
3. **Implement transcription proxy** — add `upstream.transcriptions()` and wire
|
||||
the handler in `chat.py` and `main.py`.
|
||||
|
||||
4. **Implement role fallback chain** — when `resolve_route()` finds no matching
|
||||
service for a role, walk `fallback_roles` in order before failing.
|
||||
|
||||
### P2 — Close the most important self-reported-only gaps
|
||||
|
||||
5. **Add active health probing** — the control plane should periodically probe
|
||||
registered service endpoints (a lightweight `GET /health` or `GET /v1/models`
|
||||
is sufficient) and update health state independently of node heartbeats.
|
||||
|
||||
6. **Add upstream model discovery for Ollama** — query `GET /api/tags` (Ollama)
|
||||
or `GET /v1/models` (OpenAI-compatible) from the node agent and merge loaded
|
||||
model names into the service's asset list. This enables dynamic model tracking
|
||||
without config restarts.
|
||||
|
||||
### P3 — Documentation cleanup
|
||||
|
||||
7. **Revise `architecture.md`** — remove the design-phase repo-naming rationale
|
||||
and first-implementation-sequence list; replace with a description of the actual
|
||||
running system (the four layers as implemented, data flow diagram if possible).
|
||||
|
||||
8. **Update `roadmap.md`** — this file (done).
|
||||
|
||||
---
|
||||
|
||||
## Near-Term Milestones (After P0–P3)
|
||||
|
||||
- **Live LLM demo** — run control + node against a real upstream (Ollama or
|
||||
llama.cpp) and document the end-to-end flow, including chat via role and
|
||||
direct asset addressing
|
||||
- **Validate Codex-friendly `/v1/models` offload** — test `GET /v1/models` as
|
||||
2. **Validate Codex-friendly `/v1/models` offload** — test `GET /v1/models` as
|
||||
a programmatic service catalog for a Claude Code or Codex client selecting
|
||||
a GenieHive-hosted model for lower-complexity subtasks
|
||||
- **Richer node metrics** — queue depth, in-flight count, and rolling performance
|
||||
averages reported from node to control on every heartbeat
|
||||
- **Second routing strategy** — implement `round_robin` or `least_loaded` as a
|
||||
second selectable strategy, then make `default_strategy` actually dispatch
|
||||
a GenieHive-hosted model for lower-complexity subtasks.
|
||||
|
||||
3. **`queue_depth` / `in_flight` from Ollama** — populate from `/api/ps` model
|
||||
count or from a sidecar queue tracker; currently only set from static config.
