- Add [ignore] tags around system instruction to prevent model from
identifying as "Antigravity" when asked "Who are you?"
- Replace full system instruction with minimal version used by
CLIProxyAPI/gcli2api to reduce token usage and improve response quality
Fixes#76

Adopts issue template pattern from opencode-antigravity-auth:
- Bug report template with [BUG] prefix and 6-item checklist
- Feature request template with [FEATURE] prefix
- Config disables blank issues, adds links to Google Cloud Support, TOS, and Discussions

- Add standalone Models tab with real-time quota/status display
- Move model identity table from Dashboard to Models tab
- Slim down Dashboard to KPI cards and charts only
- Dashboard charts now use unfiltered data (independent of Models filters)
Settings > Models improvements:
- Remove redundant Alias column (only Mapping is functional)
- Fix column misalignment bug (empty td)
- Add column widths and hidden row opacity styling
- Single row edit constraint (only one Mapping editable at a time)
- showHiddenModels toggle now only affects Settings (not Models tab)
- Update description text to match current functionality
i18n:
- Add 'models' and 'modelsPageDesc' keys (EN/ZH)
- Add 'modelMappingHint' for Claude CLI guidance
- Update 'modelsDesc' to reflect new functionality
Fixes issue #71 - 'No accounts available' error when API returns 429
The Google Cloud Code API can return 429 RESOURCE_EXHAUSTED errors even
when accounts have quota available due to:
- Temporary API load/throttling
- Per-minute request limits (not per-day quota)
- Transient backend issues
This fix adds:
1. A 500ms buffer after waiting for rate limits to expire
2. Optimistic rate limit reset when all accounts appear stuck
3. Retry logic that clears rate limits and tries again
The fix works in conjunction with the server-level optimistic reset
that already exists, providing multiple layers of protection against
false 'No accounts available' errors.

- Add test:emptyretry script and include in test suite
- Fix test-interleaved-thinking: use complex prompt to force thinking
- Fix test-multiturn-thinking-tools: make Turn 2 lenient (thinking optional)
- Fix test-multiturn-thinking-tools-streaming: same lenient approach
- Use TEST_MODELS helper instead of hardcoded model ID
Models may skip thinking on obvious next steps - this is valid behavior.
Tests now only require thinking on first turn to verify signatures work.

Adds comprehensive test for the empty response retry mechanism:
- Verifies EmptyResponseError class exists and works correctly
- Tests basic requests still work (no regression)
- Validates error class behavior and detection
All tests pass successfully.

Issues found by Claude Opus 4.5 + Gemini 3 Pro:
HIGH PRIORITY FIXES:
- Mark account rate-limited when 429 occurs during retry (was losing resetMs)
- Add exponential backoff between retries (500ms, 1000ms, 2000ms)
- Fix 5xx handling: don't pass error response to streamer, refetch instead
- Use recognizable error messages (429/401) for isRateLimitError/isAuthError
MEDIUM PRIORITY FIXES:
- Refactor while loop to for loop for clearer retry semantics
- Simplify logic flow with early returns

When Claude Code sends requests with large thinking_budget values,
the model may spend all tokens on "thinking" and return empty responses,
causing Claude Code to stop mid-conversation.
This commit adds a retry mechanism that:
- Throws EmptyResponseError instead of emitting fake message on empty response
- Retries up to 2 times before giving up
- Emits fallback message only after all retries are exhausted
Changes:
- src/errors.js: Added EmptyResponseError class and isEmptyResponseError()
- src/cloudcode/sse-streamer.js: Throw error instead of yielding fake message
- src/cloudcode/streaming-handler.js: Added retry loop with fallback
Tested for 6+ hours with 1,884 API requests and 88% recovery rate
on empty responses.

Ensure proper encoding for international characters in error and success pages
by specifying charset=utf-8 in Content-Type headers and adding meta charset tags.
Replace generic Error instances with NativeModuleError in loadDatabaseModule
to provide more structured error information, including rebuild status and
restart requirements. Update getAuthStatus to re-throw NativeModuleError
instances without wrapping.
Add a new error class to handle native module errors, including version mismatches and rebuild requirements. This supports the auto-rebuild functionality by providing structured error information for rebuild success and restart needs.
Remove the local clearRequireCache function from database.js and import it from
utils/native-module-helper.js. Update the function call to pass require.cache
as the second parameter for proper cache clearing.
The function has been renamed to clearRequireCache and updated to recursively
clear the require cache for a module and all its dependencies, preventing
cycles with a visited set. This improves reliability after rebuilding native
modules by ensuring complete cache invalidation. Removed unused createRequire
import as it's no longer needed.
Add detailed stdout/stderr capture and logging for failed npm rebuild commands to improve troubleshooting. Also log successful rebuild output for debugging purposes.
Improve the findPackageRoot function to correctly detect filesystem root on all platforms by checking if dirname returns the same path, replacing the Unix-specific '/' check.
When Node.js is updated, native modules like better-sqlite3 can become
incompatible due to NODE_MODULE_VERSION differences. This change adds
automatic detection and rebuild capability:
- Add native-module-helper.js utility for detecting version errors
- Lazy-load better-sqlite3 to catch import errors at runtime
- Automatically run npm rebuild when version mismatch is detected
- Clear require cache and retry loading after successful rebuild
- Provide clear instructions if automatic rebuild fails
Fixes the issue where users running via npx encounter module errors
after updating Node.js.
## Summary
Add an optional Web UI for managing accounts and monitoring quotas.
WebUI is implemented as a modular plugin with minimal changes to server.js (only 5 lines added).
## New Features
- Dashboard: Real-time model quota visualization with Chart.js
- Accounts: OAuth-based account management (add/enable/disable/refresh/remove)
- Logs: Live server log streaming via SSE with search and level filtering
- Settings: System configuration with 4 tabs
- Interface: Language (EN/zh_CN), polling interval, log buffer size, display options
- Claude CLI: Proxy connection config, model selection, alias overrides (~/.claude.json)
- Models: Model visibility and ordering management
- Server Info: Runtime info and account config reload
## Technical Changes
- Add src/webui/index.js as modular plugin (all WebUI routes encapsulated)
- Add src/config.js for centralized configuration (~/.config/antigravity-proxy/config.json)
- Add authMiddleware for optional password protection (WEBUI_PASSWORD env var)
- Enhance logger with EventEmitter for SSE log streaming
- Make constants configurable via config.json
- Merge with main v1.2.6 (model fallback, cross-model thinking)
- server.js changes: only 5 lines added to import and mount WebUI module
## Bug Fixes
- Fix Alpine.js $watch error in settings-store.js (not supported in store init)
- Fix "OK" label to "SUCCESS" in logs filter
- Add saveSettings() calls to settings toggles for proper persistence
- Improve Claude CLI config robustness (handle empty/invalid JSON files)
- Add safety check for empty config.env in claude-config component
- Improve config.example.json instructions with clear Windows/macOS/Linux paths
## New Files
- src/webui/index.js - WebUI module with all API routes
- public/ - Complete Web UI frontend (Alpine.js + TailwindCSS + DaisyUI)
- src/config.js - Configuration management
- src/utils/claude-config.js - Claude CLI settings helper
- tests/frontend/ - Frontend test suite
## API Endpoints Added
- GET/POST /api/config - Server configuration
- GET/POST /api/claude/config - Claude CLI configuration
- POST /api/models/config - Model alias/hidden settings
- GET /api/accounts - Account list with status
- POST /api/accounts/:email/toggle - Enable/disable account
- POST /api/accounts/:email/refresh - Refresh account token
- DELETE /api/accounts/:email - Remove account
- GET /api/logs - Log history
- GET /api/logs/stream - Live log streaming (SSE)
- GET /api/auth/url - OAuth URL generation
- GET /oauth/callback - OAuth callback handler
## Backward Compatibility
- Default port remains 8080
- All existing CLI/API functionality unchanged
- WebUI is entirely optional
- Can be disabled by removing mountWebUI() call
- Fix extractCodeFromInput destructuring: returns { code, state } not
{ code, extractedState }, so state validation was being bypassed
