fix: the ml artifact was in a second list I never grepped for (4311)
ac70f2a removed the `ml` image but CI went red on six tests:
`tests/test_artifact_identity.py` parametrises over its own
`ARTIFACTS = ("web", "ml", "agent", "extension")`, and every case now hits
the dispatch guard that same commit added.

My miss, and a specific one. I grepped for `fabledcurator-ml` and `ML_PATHS`
and called the survey done — but the artifact is also named as a bare `"ml"`,
which neither pattern finds. Rule 90 (grep pinned tests when changing a
shared symbol) was surfaced to me while I was making the change and I ran a
narrower sweep than it asks for. Lesson #4275 names the shape exactly: an
absence claim is only as good as the search behind it, and a grep that
matched nothing looks identical to a grep that asked the wrong question.

The re-run was done by value, not by name: every occurrence of a bare `ml` in
the repo, then filtering. That distinguishes the two things the token means —
the celery LANE `ml` and the `backend/app/services/ml` package both stay and
account for nearly every hit; only the IMAGE name went. Worth stating in the
test, since the next person to grep will hit the same ambiguity.

Also swept the prose the first pass left describing the old pipeline: "Four
artifacts" (README, ci-requirements), "leaves web and ml alone" (×5 in
build.yml, plus both docs), "CI publishes it alongside the web/ml images"
(agent/README). The run 4896 build-time measurements keep their `ml` number —
that was measured when ml was a real build — with a note saying the name has
since gone.

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.

0. Host prerequisite — NVIDIA Container Toolkit

Docker needs the toolkit to hand the GPU to a container (else: "could not select device driver nvidia with capabilities gpu"). On Arch/CachyOS:

sudo pacman -S nvidia-container-toolkit
sudo nvidia-ctk runtime configure --runtime=docker
sudo systemctl restart docker
# verify:
docker run --rm --gpus all nvidia/cuda:12.4.1-base-ubuntu22.04 nvidia-smi

1. Get a token

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

2. Pull (CI publishes it alongside the web image)

docker pull git.fabledsword.com/bvandeusen/fabledcurator-agent:latest

Local build for development instead: docker build -t fc-gpu-agent 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 \
  git.fabledsword.com/bvandeusen/fabledcurator-agent:latest

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.
