Dex Miller 8b92982112 Feature/global proxy (#596) 
* refactor(proxy): simplify logging for better readability

- Delete 17 verbose debug logs from handlers, streaming, and response_processor
- Convert excessive INFO logs to DEBUG level for internal processing details
- Add 2 critical INFO logs in forwarder.rs for failover scenarios:
  - Log when switching to next provider after failure
  - Log when all providers have been exhausted
- Fix clippy uninlined_format_args warning

This reduces log noise while maintaining visibility into key user-facing decisions.

* fix: replace unsafe unwrap() calls with proper error handling

- database/dao/mcp.rs: Use map_err for serde_json serialization
- database/dao/providers.rs: Use map_err for settings_config and meta serialization
- commands/misc.rs: Use expect() for compile-time regex pattern
- services/prompt.rs: Use unwrap_or_default() for SystemTime
- deeplink/provider.rs: Replace unwrap() with is_none_or pattern for Option checks

Reduces potential panic points from 26 to 1 (static regex init, safe).

* refactor(proxy): simplify verbose logging output

- Remove response JSON full output logging in response_processor
- Remove per-request INFO logs in provider_router (failover status, provider selection)
- Change model mapping log from INFO to DEBUG
- Change usage logging failure from INFO to WARN
- Remove redundant debug logs for circuit breaker operations

Reduces log noise significantly while preserving important warnings and errors.

* feat(proxy): add structured log codes for i18n support

Add error code system to proxy module logs for multi-language support:

- CB-001~006: Circuit breaker state transitions and triggers
- SRV-001~004: Proxy server lifecycle events
- FWD-001~002: Request forwarding and failover
- FO-001~005: Failover switch operations
- USG-001~002: Usage logging errors

Log format: [CODE] Chinese message
Frontend/log tools can map codes to any language.

New file: src/proxy/log_codes.rs - centralized code definitions

* chore: bump version to 3.9.1

* style: format code with prettier and rustfmt

Dex Miller 5376ea042b Feat/usage improvements (#508) 
* 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
- Use inline format args for better readability

This improves debugging of provider selection and failover behavior.

* feat(database): update model pricing data

- Update Claude models to full version format (e.g. claude-opus-4-5-20251101)
- Add GPT-5.2 series model pricing (10 models)
- Add GPT-5.1 series model pricing (10 models)
- Add GPT-5 series model pricing (12 models)
- Add Gemini 3 series model pricing (2 models)
- Update Gemini 2.5 series model ID format (use dot separator)
- Unify display names by removing thinking level suffixes

* fix(usage): correct Gemini output token calculation

Fix Gemini API output token parsing to use totalTokenCount - promptTokenCount
instead of candidatesTokenCount alone. This ensures thoughtsTokenCount is
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
- Update existing tests to match new calculation logic

* fix(usage): correct cache token billing and add Codex format auto-detection

- Avoid double-billing cache tokens by subtracting from input before calculation
- Add smart Codex parser that auto-detects OpenAI vs Codex API format
- Extract model name from Codex responses for accurate tracking

* fix(proxy): improve takeover detection with live config check

- 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

* Align usage stats to sliding windows

* feat(proxy): add body and header filtering for upstream requests

* feat(proxy): enable transparent passthrough for headers

- Passthrough anthropic-beta header as-is from client
- Passthrough anthropic-version header from client
- Passthrough client IP headers (x-forwarded-for, x-real-ip) by default
- 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

would block all requests causing poor UX. Now bypasses circuit breaker
check in this scenario. Also integrates model mapping into request flow.

* feat(ui): add reasoning model field to Claude provider form

Add ANTHROPIC_REASONING_MODEL configuration field for Claude providers,
allowing users to specify a dedicated model for thinking/reasoning tasks.

* feat(proxy): add openrouter_compat_mode for optional format conversion

Add configurable OpenRouter compatibility mode that enables Anthropic to
OpenAI format conversion. When enabled, rewrites endpoint to /v1/chat/completions
and transforms request/response formats. Defaults to enabled for OpenRouter.

* 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,
or Codex config.toml) instead of always using default test models.

* refactor(ui): remove timeout settings from AutoFailoverConfigPanel

Remove streaming/non-streaming timeout configuration from failover panel
as these settings have been moved to a dedicated location.

- AppProxyConfig: per-app settings (failover, timeouts, circuit breaker)

* refactor(proxy): update service layer for per-app config structure

Adapt proxy service, handler context, and provider router to use
the new per-app configuration model. Read enabled/timeout settings
from proxy_config table instead of settings table.

* feat(commands): add global and per-app proxy config commands

Add new Tauri commands for the refactored proxy configuration:
- get_global_proxy_config / update_global_proxy_config

Update TypeScript types for GlobalProxyConfig and AppProxyConfig.

* refactor(proxy): load circuit breaker config per-app instead of globally

Extract app_type from router key and read circuit breaker settings
from the corresponding proxy_config row for each application.

Jason 9196d07925 feat(proxy): sync UI when failover succeeds 
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.

Jason 5a5ca2a989 fix(proxy): resolve circuit breaker state persistence and HalfOpen deadlock 
This commit addresses several critical issues in the failover system:

**Circuit breaker state persistence (previous fix)**
- Promote ProviderRouter to ProxyState for cross-request state sharing
- Remove redundant router.rs module
- Fix 429 errors to be retryable (rate limiting should try other providers)

**Hot-update circuit breaker config**
- Add update_circuit_breaker_configs() to ProxyServer and ProxyService
- Connect update_circuit_breaker_config command to running circuit breakers
- Add reset_provider_circuit_breaker() for manual breaker reset

**Fix HalfOpen deadlock bug**
- Change half_open_requests from cumulative count to in-flight count
- Release quota in record_success()/record_failure() when in HalfOpen state
- Prevents permanent deadlock when success_threshold > 1

**Fix duplicate select_providers() call**
- Store providers list in RequestContext, pass to forward_with_retry()
- Avoid consuming HalfOpen quota twice per request
- Single call to select_providers() per request lifecycle

**Add per-provider retry with exponential backoff**
- Implement forward_with_provider_retry() with configurable max_retries
- Backoff delays: 100ms, 200ms, 400ms, etc.

Jason ebe2a665ae refactor(proxy): modularize handlers.rs to reduce code duplication 
Extract common request handling logic into dedicated modules:
- handler_config.rs: Usage parser configurations for each API type
- handler_context.rs: Request lifecycle context management
- response_processor.rs: Unified streaming/non-streaming response handling

Reduces handlers.rs from ~1130 lines to ~418 lines (-63%), eliminating
repeated initialization and response processing patterns across the
four API handlers (Claude, Codex Chat, Codex Responses, Gemini).

* fix(proxy): resolve token parsing for OpenRouter streaming responses

Problem:
- OpenRouter and similar third-party services return streaming responses
  where input_tokens appear in message_delta instead of message_start
- The previous implementation only extracted input_tokens from message_start,
  causing input_tokens to be recorded as 0 for these providers

Changes:
- streaming.rs: Add prompt_tokens field to Usage struct and include
  input_tokens in the transformed message_delta event when converting
  OpenAI format to Anthropic format
- parser.rs: Update from_claude_stream_events() to handle input_tokens
  from both message_start (native Claude API) and message_delta (OpenRouter)
  - Use if-let pattern instead of direct unwrap for safer parsing
  - Only update input_tokens from message_delta if not already set
- logger.rs: Adjust test parameters to match updated function signature

Tests:
- Add test_openrouter_stream_parsing() for OpenRouter format validation
- Add test_native_claude_stream_parsing() for native Claude API validation

* fix(pricing): standardize model ID format for pricing lookup

Normalize model IDs by removing vendor prefixes and converting dots to hyphens to ensure consistent pricing lookups across different API response formats.

Changes:
- Update seed data to use hyphen format (e.g., gpt-5-1, gemini-2-5-pro)
- Add normalize_model_id() function to strip vendor prefixes (anthropic/, openai/)
- Convert dots to hyphens in model IDs (claude-haiku-4.5 → claude-haiku-4-5)
- Try both original and normalized IDs for exact matching
- Use normalized ID for suffix-based fallback matching
- Add comprehensive test cases for prefix and dot handling
- Add warning log when no pricing found

This ensures pricing lookups work correctly for:
- Models with vendor prefixes: anthropic/claude-haiku-4.5
- Models with dots in version: claude-sonnet-4.5
- Models with date suffixes: claude-haiku-4-5-20240229

* style(rust): apply clippy formatting suggestions

Apply automatic clippy fixes for uninlined_format_args warnings across Rust codebase. Replace format string placeholders with inline variable syntax for improved readability.

Changes:
- Convert format!("{}", var) to format!("{var}")
- Apply to model_test.rs, parser.rs, and usage_stats.rs
- Fix line length issues by breaking long function calls
- Improve code formatting consistency

All changes are automatic formatting with no functional impact.

* fix(ui): restore card borders in usage statistics panels

Restore proper card styling for ModelTestConfigPanel and PricingConfigPanel by adding back border and rounded-lg classes. The transparent background styling was causing visual inconsistency.

Changes:
- Replace border-none bg-transparent shadow-none with border rounded-lg
- Apply to both loading and error states for consistency
- Format TypeScript code for better readability
- Break long function signatures across multiple lines

This ensures the usage statistics panels have consistent visual appearance with proper borders and rounded corners.

* feat(pricing): add GPT-5 Codex model pricing presets

Add pricing configuration for GPT-5 Codex variants to support cost tracking for Codex-specific models.

Changes:
- Add gpt-5-codex model with standard GPT-5 pricing
- Add gpt-5-1-codex model with standard GPT-5.1 pricing
- Input: $1.25/M tokens, Output: $10/M tokens
- Cache read: $0.125/M tokens, Cache creation: $0

This ensures accurate cost calculation for Codex API requests using GPT-5 Codex models.
