# finrod

Tiny web translator backed by Ollama on radagast. Named for Finrod Felagund, Noldor loremaster of the tongues of Men.

## Run

```sh
uv run uvicorn app:app --host 127.0.0.1 --port 8000 --reload
```

Then open http://127.0.0.1:8000.

## Config

| Env var | Default | Notes |
|---|---|---|
| `OLLAMA_URL` | `http://radagast.jpnadas.xyz:11434` | Ollama base URL |
| `MODEL_FILTER` | `gemma,aya` | Comma-separated substrings; model matches if it contains any. Empty = show all |

## Models

For Pt/Nl/En translation, three worth A/B-ing:

```sh
ssh radagast 'ollama pull gemma2:9b'      # already there — big-and-broad baseline
ssh radagast 'ollama pull gemma3:4b'      # newer multilingual training, ~2-3× faster on Ivy Bridge
ssh radagast 'ollama pull aya-expanse:8b' # Cohere multilingual model, strong on Dutch
```

All three fit in radagast's 10 GB at Q4. Switching models in the dropdown forces Ollama to load the new weights — expect a 5-15 s pause on the first call after a switch while it reads from disk.

## Build / push image

Built locally and pushed to Scaleway — no Gitea runners on the homelab yet, so there's no CI workflow.

One-time setup (host needs buildx + QEMU for cross-arch):

```sh
docker buildx create --name multi --use
docker run --privileged --rm tonistiigi/binfmt --install all
docker login rg.nl-ams.scw.cloud -u nologin -p <SCW_SECRET_KEY>
```

Then on every change:

```sh
./build.sh
```

That builds `linux/amd64,linux/arm64` and pushes three tags:
- `:latest` — moving pointer
- `:<git-short-sha>` — immutable, traceable
- `:<pyproject-version>` (e.g. `:0.1.0`) — semver

## Deploy

Cluster manifests live in `valinor/apps/finrod/` (bjw-s app-template, internal-only ingress at `finrod.jpnadas.xyz`). To roll out a new build, bump `tag:` in `valinor/apps/finrod/values.yaml` to the new semver on a branch → PR → merge → ArgoCD syncs.

## Release workflow

This project uses [Semantic Versioning](https://semver.org/) and keeps a human-edited [CHANGELOG.md](./CHANGELOG.md).

To cut a release:

1. On a branch, edit `CHANGELOG.md`: move accumulated `[Unreleased]` notes into a new `## [X.Y.Z] - YYYY-MM-DD` section.
2. Bump `version` in `pyproject.toml` to `X.Y.Z`.
3. PR → merge to `main`.
4. Tag the merge commit:
   ```sh
   git checkout main && git pull
   git tag -a vX.Y.Z -m "vX.Y.Z"
   git push origin vX.Y.Z
   ```
5. `./build.sh` — the image now also gets `:X.Y.Z` (read from `pyproject.toml`).
6. In `valinor`, bump `apps/finrod/values.yaml` `tag:` from the previous version to `X.Y.Z` on a branch → PR → ArgoCD picks it up.
