# AI-spel static asset service
- Own only public, version-pinned Piper and ONNX speech assets.
- Serve under `/static/` on `https://ai-spel.k3s.k0.nu`.
- `VERSION` is the only release version source. Use `scripts/bump-version.py`.
- Gitea Actions on the existing `large` runner verifies, builds, and publishes. Never run tests, builds, containers, images, or binaries locally; do not create runners.
- Git release commit/tag, image, Helm chart, and manifest use the same version.
- Use Harbor project `ai-spel`, Argo CD project `ai-spel`, and Kubernetes namespace `ai-spel`.
- `/static/piper-wasm-v1/` is immutable and cached for one year. Incompatible asset updates require a new path and coordinated frontend change.
- No secrets or runtime network access.

Swedish Piper voice models
==========================
This service distributes the Swedish medium Piper models Alma, Lisa, and NST
from the rhasspy/piper-voices repository, pinned to revision
c10ece1aade47bb51c153c893d14e5bf8e5b7117. Model weights are published under
/static/piper-wasm-v1/voices/ after integrity verification in CI.
Alma (sv_SE-alma-medium)
Source: https://huggingface.co/rhasspy/piper-voices/tree/c10ece1aade47bb51c153c893d14e5bf8e5b7117/sv/sv_SE/alma/medium
The model card states CC BY 4.0 and identifies the upstream voice project at
https://huggingface.co/yeagersthlm/piper-voice-sv-alma.
Lisa (sv_SE-lisa-medium)
Source: https://huggingface.co/rhasspy/piper-voices/tree/c10ece1aade47bb51c153c893d14e5bf8e5b7117/sv/sv_SE/lisa/medium
The upstream model card describes this as fine-tuned from the Norwegian
talesyntese medium voice.
NST (sv_SE-nst-medium)
Source: https://huggingface.co/rhasspy/piper-voices/tree/c10ece1aade47bb51c153c893d14e5bf8e5b7117/sv/sv_SE/nst/medium
The upstream model card identifies the NST Swedish TTS dataset as CC0 and
credits KBLab at the National Library of Sweden for training the voice.
The upstream model files and model cards remain the source of truth for license
terms. Exact source revision and per-file integrity checks are in
scripts/assets.mjs.

# AI-spel static assets
This repository publishes Piper/ONNX runtime assets and Swedish voice models through a dedicated Nginx service. The game keeps the same origin: ingress routes `/static/` here, `/` to the frontend, and `/api` to Rust.
The service contains only public, version-pinned files. Gitea Actions on the existing `large` runner downloads and verifies model files, runs checks, builds a `linux/amd64` image, bumps the patch version, and publishes the image, Helm chart, and rendered manifest to Harbor. Argo CD tracks the latest chart in the existing `ai-spel` project and namespace.
## Asset URLs and caching
Assets under `/static/piper-wasm-v1/` are served with `Cache-Control: public, max-age=31536000, immutable`. Keep this path and its contents stable. To change assets, publish under a new asset path and update the frontend to reference it after the new static release is healthy.
- `/static/piper-wasm-v1/voices/` — Alma, Lisa, and NST Swedish voices, plus attribution.
- `/static/piper-wasm-v1/onnx/` — ONNX Runtime WASM and ES module loader.
- `/static/piper-wasm-v1/piper/` — Piper phonemizer WASM and data.
- `/static/version.txt` — active deployment version, without long-lived caching.
The frontend worker remains bundled with the frontend; it fetches these large assets from same-origin static URLs. The browser does not request models from an external host.
## Argo CD bootstrap
After the first chart has been published, bootstrap the app once from `deploy/argocd/application.yaml`:
```sh
kubectl -n argocd apply -f deploy/argocd/application.yaml
```
It tracks the newest chart (`*`), uses automated sync/self-heal without pruning, and deploys to `ai-spel`. Later releases do not need manual Argo actions.
## Local policy
Do not build or run locally. CI runs static checks, tests, image build, and Helm lint/render on the existing runner; runtime verification happens on Kubernetes.
