## Summary
- Add provider quota usage to an expanded-by-default subsection in the
session Status panel.
- Resolve the active provider and model automatically from the current
session.
- Display localized quota windows, reset times, values, and color-coded
progress bars inside the same bordered rounded container used by
neighboring subsections.
## Server implementation
- Add GET /api/usage/:providerId with optional modelId filtering.
- Add a 60-second in-memory cache and deduplicate concurrent provider
requests.
- Read credentials only on the server and never return secrets through
the API.
- Support Claude, Codex, GitHub Copilot, Google/Gemini/Antigravity,
Kimi, NanoGPT, OpenRouter, z.ai, Zhipu, MiniMax global/CN, Cursor,
Ollama Cloud, Wafer, and OpenCode Go.
- Use existing OpenCode and Antigravity access tokens for Google calls;
optional environment-provided OAuth client values are required only for
token refresh.
## UI behavior
- Keep Provider usage open by default while allowing it to collapse like
the other Status subsections.
- Show loading, unsupported, not configured, unavailable, and no-session
states.
- Localize all user-visible strings across the nine existing locales.
## Attribution
- Include the MIT notice for the OpenChamber usage-provider
implementation used as the reference.
## Validation
- Server typecheck
- UI typecheck
- 7 targeted usage tests
- Production UI build
- Server build and npm package-content verification
- Tauri release build without bundling
- git diff checks
