## Description
|
|
|
|
<!-- SECTION:DESCRIPTION:BEGIN -->
|
|
`MusicLibrary.Repo.extension_path/1` raises `"Unsupported OS or platform"` when run on an unrecognised OS/architecture combination. This is called at startup via `config/runtime.exs` to resolve paths for `unicode` and `vec0` SQLite extensions.
|
|
|
|
Instead of silently degrading (which would cause confusing downstream failures), add early detection:
|
|
|
|
1. Add `MusicLibrary.Repo.supported_platform?/0` that returns a boolean
|
|
2. In `config/runtime.exs`, check this BEFORE the `load_extensions` config block
|
|
3. If unsupported, raise with a helpful message listing supported platforms and the detected OS/arch
|
|
|
|
The existing `raise` in `extension_path/1` stays as a defensive fallback (should not be reached if runtime.exs catches it first).
|

## Acceptance Criteria
|
|
<!-- AC:BEGIN -->
|
|
- [x] #1 #1 `Repo.supported_platform?/0` returns true/false based on OS/arch
|
|
- [x] #2 #2 `config/runtime.exs` checks `supported_platform?/0` before loading extensions and raises with a helpful message on unsupported platforms
|
|
- [x] #3 #3 Existing supported platforms (darwin-amd64, darwin-arm64, linux-amd64, linux-arm64) continue to load extensions correctly
|
|
- [x] #4 #4 `extension_path/1` raise stays as a defensive fallback
|
