 ## Status
 
-Pre-v1. Not yet functional.
+In production. `main` is continuously deployed — every merge to `main` builds
+and publishes `:latest` images, so whatever is on `main` is what is running.
+Day-to-day work happens on `dev`, which publishes `:dev` images.
+
+## What's in here
+
+Five deployable pieces, built by `.forgejo/workflows/build.yml`:
+
+| Piece | Built from | Image | Role |
+| --- | --- | --- | --- |
+| **Web / workers** | `Dockerfile` | `fabledcurator` | Quart API + the built Vue SPA in one image. `entrypoint.sh` picks the role: `web`, `worker`, `scheduler`. The `maintenance-long` service is a second `worker` pinned to the long-running maintenance queue. |
+| **ML worker** | `Dockerfile.ml` | `fabledcurator-ml` | Same app, plus `requirements-ml.txt` — tagging and embedding models that run in-container. |
+| **GPU agent** | `agent/Dockerfile` | `fabledcurator-agent` | Optional desktop-GPU worker (`agent/`). Leases jobs over **HTTP only** — never touches the database or Redis. Run it for a burst, stop it to reclaim the card. See `agent/README.md`. |
+| **Firefox extension** | `extension/` | signed XPI | MV3 extension: pushes platform session cookies into FC and adds a creator as a Source in one click. AMO-signed on `main` only, then bundled into the web image and served from Settings → Maintenance. See `extension/README.md`. |
+| **Data** | — | `pgvector/pgvector:pg16`, `redis:7-alpine` | Postgres with pgvector for embeddings; Redis as the Celery broker. |

+The GPU agent is deployed separately, on the machine with the card —
+`agent/docker-compose.yml`, not this stack.
+
 ## Deployment posture
 
 FabledCurator is designed to run inside a self-hosted homelab environment over plain HTTP. If you want TLS, terminate it at your reverse proxy. The app does not generate certificates, redirect to HTTPS, or set HSTS.
 
 ## CI / Forgejo setup
 
-The repo's workflows expect:
+Three workflows: `ci.yml` (lint, extension-version guard, backend unit tests,
+frontend build, integration), `extension.yml` (extension lint, vitest, XPI
+content verification), and `build.yml` (sign + publish).
 
-- **Runner label `python-ci`** — a Forgejo runner with Python 3.14, ruff, and Node 22 pre-installed. Both `ci.yml` and `build.yml` use this label. The runner image (`runner-base:python-ci`) is built from `CI-Runner/CI-python/` in the operator's workspace; `make push` from that directory builds and pushes a new image when toolchain pins change.
-- **Repo secret `RELEASE_TOKEN`** — a Forgejo PAT with the following scopes:
+**The toolchain each job runs in is its `container.image`, not its `runs-on`
+label.** `runs-on: python-ci` only schedules the job onto a runner; every job
+then names the image it actually wants. `ci-requirements.md` is the current,
+authoritative list of images and per-job installs — read that rather than a
+copy here, so the two can't drift.
+
+The repo expects one secret:
+
+- **`RELEASE_TOKEN`** — a Forgejo PAT with:
   - `write:package` + `read:package` — for `docker push` to `git.fabledsword.com`
-  - `write:release` — for future release-cutting workflows
-  - `write:issue` — for future issue-management automation
+  - `write:release` — for the `ext-<version>` releases that cache the signed XPI
+  - `write:issue` — for issue-management automation
 
   Generate at https://git.fabledsword.com/user/settings/applications. The injected `GITHUB_TOKEN` cannot be used because it lacks `write:package`.
 
+AMO signing additionally needs `MOZILLA_AMO_JWT_KEY` / `MOZILLA_AMO_JWT_SECRET`; it runs on
+`main` only and is cached per version, since AMO rejects a re-signed version.
