* i18n: update cache terminology across all languages
- Change 'Cache Read' to 'Cache Hit' in all languages
- Change 'Cache Write' to 'Cache Creation' in all languages
- Update zh: 缓存读取 → 缓存命中, 缓存写入 → 缓存创建
- Update en: Cache Read → Cache Hit, Cache Write → Cache Creation
- Update ja: キャッシュ読取 → キャッシュヒット, キャッシュ書込 → キャッシュ作成
Affected keys: cacheReadTokens, cacheCreationTokens, cacheReadCost,
cacheWriteCost, cacheRead, cacheWrite
* feat(usage): add cache metrics to trend chart
- Add cache creation tokens visualization (orange line)
- Add cache hit tokens visualization (purple line)
- Add gradient definitions for new cache metrics
- Include cache data in hourly aggregation
- Display cache metrics alongside input/output tokens
This provides better visibility into cache usage patterns over time.
* fix(usage): fix timezone handling in datetime picker
- Add timestampToLocalDatetime() to convert Unix timestamp to local datetime
- Add localDatetimeToTimestamp() with validation for incomplete input
- Fix issue where typing hours/minutes would jump to previous day
- Validate datetime format completeness before conversion
- Use local timezone instead of UTC for datetime-local input
This resolves the issue where users couldn't fine-tune time selection
and the input would jump unexpectedly when editing hours or minutes.
* feat(usage): add auto-refresh for usage statistics
- Add 30-second auto-refresh interval for all usage queries
- Disable background refresh to save resources
- Apply to: summary, trends, provider stats, model stats, request logs
- Queries automatically update when tab is active
- Pause refresh when user switches to another tab
This keeps usage data fresh without manual refresh.
* fix(proxy): improve usage logging and cache token parsing
- Log requests even when usage parsing fails (with default values)
- Add detailed debug logging for usage metrics
- Support cache_read_input_tokens field in Codex responses
- Fallback to input_tokens_details.cached_tokens if needed
- Add test case for cached_tokens in input_tokens_details
- Ensure all requests are tracked in database for analytics
This fixes missing request logs when API responses lack usage data
and improves cache token detection across different response formats.
* style(rust): use inline format args in format! macros
- Replace format!("...", var) with format!("...{var}")
- Update universal provider ID formatting
- Update error message formatting
- Update config.toml generation in Codex provider
Fixes clippy::uninlined_format_args warnings.
* feat(proxy): enhance provider router logging
- Add debug logs for failover queue provider count
- Log circuit breaker state for each provider check
- Add logs for missing current provider scenarios
- Log when no current provider is configured

included in output statistics.
- Update from_gemini_response to calculate output from total - input
- Update from_gemini_stream_chunks with same logic for consistency
- Fix from_codex_stream_events to use adjusted token calculation
- Add test case for responses with thoughtsTokenCount

- Add live config takeover detection for hot-switch decision
- Rebuild takeover when backup is missing or placeholder remains
- Make detect_takeover_in_live_config_for_app public
- Fix is_takeover_active to use actual takeover status
* refactor(usage): simplify model pricing lookup by removing suffix fallback
Replace complex suffix-stripping fallback with direct prefix/suffix cleanup.
Model IDs are now cleaned by removing vendor prefix (before /) and colon
suffix (after :), then matched exactly against pricing table.
* feat(database): add Chinese AI model pricing data
Add pricing for domestic AI models (CNY/1M tokens):
- Doubao-Seed-Code (ByteDance)
- DeepSeek V3/V3.1/V3.2
- Kimi K2/K2-Thinking/K2-Turbo (Moonshot)
- MiniMax M2/M2.1/M2.1-Lightning
- GLM-4.6/4.7 (Zhipu)
- Mimo V2 Flash (Xiaomi)
Also fix test case to use correct model ID and remove invalid currency column.
* refactor(proxy): improve header forwarding with blacklist approach
Change from whitelist to blacklist mode for request header forwarding.
Only skip headers that will be overridden (auth, host, content-length).
This preserves client's original headers and improves compatibility.
* fix(proxy): bypass timeout and retry configs when failover is disabled
When auto_failover_enabled is false, timeout and retry configurations
should not affect normal request flow. This change ensures:
- create_forwarder: passes 0 for all timeout/retry params when failover
is disabled, effectively bypassing these checks
- streaming_timeout_config: returns 0 for both first_byte_timeout and
idle_timeout when failover is disabled
This prevents unnecessary timeout errors and retry attempts when users
have explicitly disabled the failover feature.
* fix(proxy): handle zero value input in failover config fields
* refactor(proxy): remove retry logic and add enabled check for failover
* refactor(proxy): distinguish circuit-open from no-provider errors

- Filter private params (underscore-prefixed fields) from request body
- No database changes required
* feat(proxy): extract session ID from client requests for logging
- Add SessionIdExtractor to parse session ID from Claude/Codex requests
- Support extraction from metadata.user_id, headers, previous_response_id
- Pass session_id through RequestContext to usage logger
- Enable request correlation by session in proxy_request_logs
- Change from UTC to local timezone for daily/hourly trends
- Use SQLite 'localtime' modifier for date grouping
- Replace single().unwrap() with earliest().unwrap_or_else()
to handle DST transition edge cases gracefully
On Windows, npx, npm, yarn, pnpm, node, bun, and deno are actually
.cmd batch files that require cmd /c wrapper to execute properly.
This fixes the Claude Code /doctor warning:
"Windows requires 'cmd /c' wrapper to execute npx"
The transformation is applied when exporting MCP config to ~/.claude.json:
- Before: {"command": "npx", "args": ["-y", "foo"]}
- After: {"command": "cmd", "args": ["/c", "npx", "-y", "foo"]}
Uses conditional compilation (#[cfg(windows)]) for zero overhead on
other platforms.
Closes#453
On Windows, opening the Settings > About section would spawn three
terminal windows when checking CLI tool versions (claude, codex, gemini).
Root cause:
- scan_cli_version() directly executed .cmd files, but child processes
(node.exe) spawned by these batch scripts didn't inherit CREATE_NO_WINDOW
- PATH separator used Unix-style ":" instead of Windows ";"
Fix:
- Wrap command execution with `cmd /C` to ensure all child processes
run within the same hidden console session
- Use platform-specific PATH separators via conditional compilation
* fix(schema): add missing base columns migration for proxy_config
Add compatibility migration for older databases that may be missing
the basic proxy_config columns (proxy_enabled, listen_address,
listen_port, enable_logging) before adding newer timeout fields.
* fix: add proxy_config base column patches for v3.9.0-2 upgrade
Add base config column patches in create_tables_on_conn():
- proxy_enabled
- listen_address
- listen_port
- enable_logging
Ensures v3.9.0-2 users (user_version=2 but missing columns)
can properly upgrade with all required fields added.
* fix: migrate proxy_config singleton to per-app on startup for v2 databases
Add startup migration for legacy proxy_config tables that still have
singleton structure (no app_type column) even with user_version=2.
This fixes the issue where v3.9.0-2 databases with v2 schema but legacy
proxy_config structure would fail with "no such column: app_type" error.
- Call migrate_proxy_config_to_per_app in create_tables_on_conn
- Add regression test to verify the fix

* fix(mcp): 移除同步Codex Provider时的旧MCP同步调用
sync_enabled_to_codex使用旧的config.mcp.codex结构，
在v3.7.0统一结构中该字段为空，导致MCP配置被错误清除。
MCP同步应通过McpService进行。
Fixes#403
* test(mcp): update test to reflect new MCP sync architecture
Remove MCP-related assertions from sync_codex_provider_writes_auth_and_config
test since provider switching no longer triggers MCP sync in v3.7.0+.
MCP synchronization is now handled independently by McpService,
not as part of the provider switch flow.

On macOS, the auto-launch library requires the .app bundle path (e.g.,
/Applications/CC Switch.app) rather than the binary path inside the bundle
(e.g., .app/Contents/MacOS/CC Switch). Using the binary path directly
causes AppleScript login items to open a terminal window.
This fix extracts the .app bundle path from current_exe() on macOS,
ensuring proper integration with macOS login items.
Closes#375

* feat: add sync functionality and JSON preview for Universal Provider
* fix: add missing in_failover_queue field to Provider structs
After rebasing to main, the Provider struct gained a new
`in_failover_queue` field. This fix adds the missing field
to the three to_*_provider() methods in UniversalProvider.
* refactor: redesign AddProviderDialog with tab-based layout
- Add tabs to separate app-specific providers and universal providers
- Move "Add Universal Provider" button from panel header to footer
- Remove unused handleAdd callback and clean up imports
- Update emptyHint i18n text to reference the footer button
* fix: append /v1 suffix to Codex base_url in Universal Provider
Codex uses OpenAI-compatible API which requires the /v1 endpoint suffix.
The Universal Provider now automatically appends /v1 to base_url when
generating Codex provider config if not already present.
- Handle trailing slashes to avoid double slashes
- Apply fix to both backend (to_codex_provider) and frontend preview
* feat: auto-sync universal provider to apps on creation
Previously, users had to manually click sync after adding a universal
provider. Now it automatically syncs to Claude/Codex/Gemini on creation,
providing a smoother user experience.

* feat(ui): add OpenRouter compatibility mode toggle
Add UI toggle for OpenRouter providers to enable/disable compatibility
mode which uses OpenAI Chat Completions format with SSE conversion.
* feat(stream-check): use provider-configured model for health checks
Extract model from provider's settings_config (ANTHROPIC_MODEL, GEMINI_MODEL,

Add column check in create_tables to handle existing v2 databases
that were created before the failover queue refactor.
* fix(ui): differentiate active provider border color by proxy mode
- Use green border/gradient when proxy takeover is active
- Use blue border/gradient in normal mode (no proxy)
- Improves visual distinction between proxy and non-proxy states
* fix(database): clear provider health record when removing from failover queue
When a provider is removed from the failover queue, its health monitoring
is no longer needed. This change ensures the health record is also deleted
from the database to prevent stale data.

- Add Tauri commands and frontend API integration
- Add toggle in WindowSettings with i18n support (en/zh/ja)
- Fix hardcoded Chinese text in tests to use i18n keys
OpenRouter now supports Claude Code compatible endpoint (/v1/messages),
eliminating the need for Anthropic ↔ OpenAI format conversion.
- Disable format transformation for OpenRouter (keep old logic as fallback)
- Pass through original endpoint instead of redirecting to /v1/chat/completions
- Add anthropic-version header for ClaudeAuth and Bearer strategies
- Update tests to reflect new passthrough behavior
Tauri 2.0 platform config merging is shallow, not deep. The Windows
config only specified titleBarStyle, causing minWidth/minHeight to
be missing on Windows. This allowed users to resize the window below
900px, causing header elements to misalign.
- Add support for ANTHROPIC_API_KEY in Claude auth extraction
- Only update existing token fields during sync, avoid adding fields
that weren't originally configured by the user
- Add tests for both scenarios
- Detect takeover residue in Live configs even when proxy is not running

* fix(ui): improve AboutSection styling and version detection
- Add framer-motion animations for smooth page transitions
- Unify button sizes and add icons for consistency
- Add gradient backgrounds and hover effects to cards
- Add notInstalled i18n translations (zh/en/ja)
- Fix version detection when stdout/stderr is empty
* fix(proxy): persist per-app takeover state across app restarts
- Fix proxy toggle color to reflect current app's takeover state only
- Restore proxy service on startup if Live config is still in takeover state
- Preserve per-app backup records instead of clearing all on restart
- Only recover Live config when proxy service fails to start
The #[cfg(target_os = "macos")] restriction was a historical artifact
from when RunEvent was only used for macOS-specific events (Reopen, Opened).
After c9ea13a added ExitRequested handling for all platforms, the import
should have been updated but was overlooked.
Add guard functions to check if Claude/Codex/Gemini CLI has been
initialized before attempting to sync MCP configurations. This prevents
creating unwanted config files in directories that don't exist.
- Claude: check ~/.claude dir OR ~/.claude.json file exists
- Codex: check ~/.codex dir exists
- Gemini: check ~/.gemini dir exists
When the target app is not installed, sync operations now silently
succeed without writing any files, allowing users to manage MCP servers
for apps they actually use without side effects on others.
- Remove server from live config when app is disabled during upsert
- Merge enabled flags instead of overwriting when importing from multiple apps
- Normalize Gemini MCP type field (url-only → sse, command → stdio)
- Use atomic write for Codex config updates
- Add tests for disable-removal, multi-app merge, and Gemini SSE import
Replace global live takeover with granular per-app control:
- Add start_proxy_server command (start without takeover)
- Add get_proxy_takeover_status to query each app's state
- Add set_proxy_takeover_for_app for individual app control
- Use live backup existence as SSOT for takeover state
- Refactor sync_live_to_provider to eliminate code duplication
- Update ProxyToggle to show status per active app
- Update Codex `model_providers.<model_provider>.base_url` to the proxy origin with `/v1`
- Add route fallbacks for `/responses` and `/chat/completions` (plus double-`/v1` safeguard)
- Add unit tests for the TOML base_url takeover logic
- Set takeover flag before writing proxy config to fix race condition
where crash during takeover left Live configs corrupted but flag unset
- Add fallback detection by checking for placeholder tokens in Live
configs when backups exist but flag is false (handles legacy/edge cases)
- Improve error handling with proper rollback at each stage of startup
- Clean up stale backups when Live configs are not in takeover state
to avoid long-term storage of sensitive tokens
Previously, UI sync was triggered only when failover happened (retry count > 1).
This missed cases where the first provider in the failover queue succeeded but
was different from the user's selected provider in settings.
Now we capture the current provider ID at request start and compare it with
the actually used provider. This ensures UI/tray always reflects the real
provider handling requests.
This commit addresses two critical issues in the proxy failover logic:
1. Circuit Breaker HalfOpen Concurrency Bug:
- Introduced `AllowResult` struct to track half-open permit usage
- Added state guard in `transition_to_half_open()` to prevent duplicate resets
- Replaced `fetch_sub` with CAS loop in `release_half_open_permit()` to prevent underflow
- Separated `is_available()` (routing) from `allow_request()` (permit acquisition)
2. Error Classification Conflation:
- Split retry logic into `should_retry_same_provider()` and `categorize_proxy_error()`
- Same-provider retry: only for transient errors (timeout, 429, 5xx)
- Cross-provider failover: now includes ConfigError, TransformError, AuthError
- 4xx errors (401/403) no longer waste retries on the same provider
- Skip live writes when takeover is active and proxy is running
- Refresh live backups from provider edits during takeover
- Sync live tokens to DB without clobbering real keys with placeholders
- Avoid injecting extra placeholder keys into Claude live env
- Reapply takeover after proxy listen address/port changes
- In takeover mode, edit dialog uses DB config and keeps API key state in sync
* feat(proxy): add error mapper for HTTP status code mapping
- Add error_mapper.rs module to map ProxyError to HTTP status codes
- Implement map_proxy_error_to_status() for error classification
- Implement get_error_message() for user-friendly error messages

* Merge branch 'main' into feature/error-request-logging
- Remove `is_proxy_target` field from Provider struct (Rust & TypeScript)
- Remove related DAO methods: get_proxy_target_provider, set_proxy_target
- Remove deprecated Tauri commands: get_proxy_targets, set_proxy_target
- Add `is_available()` method to CircuitBreaker for availability checks
without consuming HalfOpen probe permits (used in select_providers)
- Keep `allow_request()` for actual request gating with permit tracking
- Update stream_check to use failover_queue instead of is_proxy_target
- Clean up commented-out reset circuit breaker button in ProviderActions
- Remove unused useProxyTargets and useSetProxyTarget hooks
Clear all provider_health records when stopping the proxy server,
ensuring health badges reset to "healthy" state. This fixes the
inconsistency where circuit breakers (in memory) would reset on
stop but health badges (in database) would retain stale state.
Previously, only 429, 408, and 5xx errors triggered failover to the next
provider. Other 4xx errors (like 400) were considered non-retryable and
caused immediate disconnection.
This was problematic because different providers have different restrictions
(e.g., "Do not use this API outside Claude Code CLI"), and a 400 error from
one provider doesn't mean other providers will fail.
Now all upstream HTTP errors trigger failover, allowing the system to try
all configured providers before giving up.
Add FailoverSwitchManager to handle provider switching after successful
failover. This ensures the UI reflects the actual provider in use:
- Create failover_switch.rs with deduplication and async switching logic
- Pass AppHandle through ProxyService -> ProxyServer -> RequestForwarder
- Update is_current in database when failover succeeds
- Emit provider-switched event for frontend refresh
- Update tray menu and live backup synchronously
The switching runs asynchronously via tokio::spawn to avoid blocking
API responses while still providing immediate UI feedback.
- Make usage script credential fields optional with provider config fallback
- Optimize multi-plan card display: show plan count by default, expandable for details
- Add hint text to explain credential fallback mechanism
- Fix HalfOpen counter underflow: increment half_open_requests when
transitioning from Open to HalfOpen to prevent underflow in
record_success/record_failure
- Fix Gemini config field names: unify to GEMINI_API_KEY and
GOOGLE_GEMINI_BASE_URL (removed GOOGLE_API_KEY and GEMINI_API_BASE)
- Fix Codex proxy takeover: write base_url to config.toml instead of
OPENAI_BASE_URL in auth.json (Codex CLI reads from config.toml)
