 ## CI
 
-`.gitea/workflows/ci.yaml` runs `go vet` and `go test` for all four modules (`gen`, `ai-gateway`, `ha-gateway`, `discord-bot`), then builds and pushes Docker images for the three services on pushes to `main`.
+`.gitea/workflows/ci.yaml` runs `go vet` and `go test` for all five modules (`gen`, `ai-gateway`, `ha-gateway`, `discord-bot`, `tts-gateway`), then builds and pushes Docker images for `ai-gateway`, `ha-gateway`, and `discord-bot` on pushes to `main`. `tts-gateway` is deliberately excluded from the build/push step for now — its production image (CUDA base, model artifact distribution, etc.) is a separate decision, not yet made. Note that `ai-gateway/Dockerfile`, `ha-gateway/Dockerfile`, and `discord-bot/Dockerfile` each `COPY` every other service directory (not just their own) because `go.work` lists all five modules as workspace members — Go's workspace-mode module resolution needs every listed directory present in the build context, even ones a given service doesn't otherwise depend on. Adding a new module to `go.work` means adding a matching `COPY` line to the other Dockerfiles too, or their builds break.
