feat(agent): desktop GPU agent container — CCIP + figure crops over HTTP (#114)
The last piece: a Dockerised desktop-GPU worker that talks to FC ONLY over HTTP
(lease → fetch pixels → detect figures + CCIP-embed → submit), so Redis/Postgres
stay private. New top-level agent/ (outside CI scope — verified by running it):
- fc_agent/worker.py: the lease/compute/submit loop, concurrency 1, start/pause/
  stop (stop frees the card; unprocessed leases expire + re-queue).
- fc_agent/models.py: imgutils wrappers — detect_person (figures) + CCIP embed.
  The two API seams to verify against the installed dghs-imgutils (flagged).
- fc_agent/media.py: stills + video frame sampling (ffmpeg) at FC's cadence →
  per-frame instances (the bag).
- fc_agent/crops.py: vendored crop primitive. client.py: the FC HTTP client.
- fc_agent/app.py: FastAPI localhost control UI (start/pause/stop + progress +
  queue depth). Dockerfile (CUDA + onnxruntime-gpu + ffmpeg) + requirements +
  README (token → build → run --gpus all → Start; CPU-fallback path).

This completes the CCIP pipeline end to end: agent produces region CCIP vectors →
RegionService stores → matcher suggests characters → rail. Verified by running on
the desktop (not CI). README calls out the imgutils API + model-string checks.

FabledCurator GPU agent

A desktop-GPU worker that embeds characters (CCIP) + figure crops for FabledCurator. It talks to FC only over HTTP — it leases jobs, fetches image pixels, runs the models on your GPU, and posts results back. Your FC database and Redis stay private; the agent never touches them.

You run it when you want a burst and stop it to reclaim the card.

1. Get a token

In FC: Settings → Tagging → GPU agent → Generate token (or Rotate). Copy it.

2. Build

cd agent
docker build -t fc-gpu-agent .

3. Run (on the machine with the GPU)

docker run --rm --gpus all -p 8770:8770 \
  -e FC_URL=http://curator.traefik.internal \
  -e FC_TOKEN=<paste-the-token> \
  -v fc-agent-models:/models \
  fc-gpu-agent

Then open http://localhost:8770 — the control page. Click Start to begin draining the queue; Pause/Stop to yield the GPU. The -v fc-agent-models volume caches the downloaded ONNX models so restarts are fast.

Kick off a backfill from FC (GPU agent card → Queue character embedding), then watch the queue counts on the control page (or FC's card) drain.

Config (env)

var default meaning
FC_URL http://localhost:8000 FC base URL
FC_TOKEN the bearer token (required)
AGENT_ID desktop-agent identifies this agent's leases
BATCH_SIZE 4 jobs leased per round (still processed one at a time)
CCIP_MODEL imgutils default CCIP model name
DETECTOR_LEVEL m person-detector size: n < s < m < x
POLL_IDLE_SECONDS 10 wait between empty leases

⚠️ Verify on first run

This part can't be CI-tested (no GPU/models in CI), so confirm against your installed dghs-imgutils (pip show dghs-imgutils) — see fc_agent/models.py:

  • imgutils.detect.detect_person(image, level=...) returns [((x0,y0,x1,y1), label, score), ...].
  • imgutils.metrics.ccip_extract_feature(image, model=...) returns a vector (768-d for caformer). If you want the F1-0.94 variant, set CCIP_MODEL=ccip-caformer_b36-24 (verify the exact string in imgutils).

If FC's matcher under/over-fires, tune the cosine threshold in backend/app/services/ml/ccip.py (DEFAULT_SIM_THRESHOLD) and use GET /api/ccip/overview + /api/ccip/images/<id> to spot-check.

CPU fallback

Swap onnxruntime-gpuonnxruntime in requirements.txt and drop --gpus all to grind it slowly on the server instead. Same agent, no card.
