feat: add project profiles for snapshot-based config switching
Add a profile feature that captures the current provider, MCP, skills and prompt state for Claude Code and Codex as a named snapshot, and re-applies it in one click from the header switcher or the tray Projects submenu. - New profiles table (schema v12) with current marker in settings - ProfileService orchestrates the four existing switch primitives (provider first, then MCP diff, skills diff, prompt enable) - Best-effort apply: dangling references become warnings, no rollback - Header combobox switcher + snapshot-style manage dialog - Tray Projects submenu shared with the UI apply/event pipeline - i18n for zh/en/ja/zh-TW under the new profiles domain - Integration tests covering roundtrip, dangling refs and clear |

feat(providers): seed an official preset on startup for Claude/Codex/Gemini
New and existing users now see a built-in "Claude Official" / "OpenAI Official" / "Google Official" entry in their provider list, so switching back to the official endpoint is one click away instead of buried in the README. - New providers_seed.rs holds the three seeds (id, name, settings_config, icon) keyed by AppType, with a single is_official_seed_id() helper that scans OFFICIAL_SEEDS so the id list has one source of truth. - Database::init_default_official_providers() runs once per database (gated by an official_providers_seeded setting flag), appends each seed to the end of the sort order, and never touches is_current. - Startup also auto-imports the live config (settings.json / auth.json / .env) as a "default" provider before seeding, so users with an existing manual config don't lose it when they click the official preset. - Database::has_non_official_seed_provider() replaces the get_all_providers call in import_default_config's gating check with an id-only scan, dropping the N+1 endpoint sub-queries from every startup. |

feat: add usage daily rollups, incremental auto-vacuum, and sync-aware backup
- Add usage_daily_rollups table (schema v6) to aggregate proxy request logs into daily summaries, reducing query overhead for statistics - Add rollup_and_prune DAO that aggregates old detail logs (>N days) into rollup rows and deletes the originals - Update all usage stats queries to UNION detail logs with rollup data - Introduce incremental auto-vacuum for SQLite, with startup and periodic cleanup of old stream_check_logs and request log rollups - Split backup export/import into full vs sync variants: WebDAV sync now skips local-only table data (proxy_request_logs, stream_check_logs, provider_health, proxy_live_backup, usage_daily_rollups) while preserving them on import - Add enable_logging guard to skip request log writes when disabled - Apply cargo fmt formatting fixes across multiple modules |

refactor: remove OMO common config two-layer merge system
Each OMO provider now stores its complete configuration directly in settings_config.otherFields instead of relying on a shared OmoGlobalConfig merged at write time. This simplifies the data flow from a 4-tuple (agents, categories, otherFields, useCommonConfig) to a 3-tuple and eliminates an entire DB table, two Tauri commands, and ~1700 lines of merge/sync code across frontend and backend. Backend: - Delete database/dao/omo.rs (OmoGlobalConfig struct + get/save methods) - Remove get/set_config_snippet from settings DAO - Remove get/set_common_config_snippet Tauri commands - Replace merge_config() with build_config() in services/omo.rs - Simplify OmoVariant (remove config_key, known_keys) - Simplify import_from_local and build_local_file_data - Rewrite all OMO service tests Frontend: - Delete OmoCommonConfigEditor.tsx and OmoGlobalConfigFields.tsx - Delete src/lib/api/config.ts - Remove OmoGlobalConfig type and merge preview functions - Remove useGlobalConfig/useSaveGlobalConfig query hooks - Simplify useOmoDraftState (remove all common config state) - Replace OmoCommonConfigEditor with read-only JsonEditor preview - Clean i18n keys (zh/en/ja) |

feat: add Universal Provider feature (#348)
* feat: add Universal Provider feature - Add Universal Provider data structures and type definitions - Implement backend CRUD operations and sync functionality - Add frontend UI components (UniversalProviderPanel, Card, FormModal) - Add NewAPI icon and preset configuration - Support cross-app (Claude/Codex/Gemini) configuration sync - Add website URL field for providers - Implement real-time refresh via event notifications - Add i18n support (Chinese/English/Japanese) * feat: integrate universal provider presets into add provider dialog - Add universal provider presets (NewAPI, Custom Gateway) to preset selector - Show universal presets with Layers icon badge in preset selector - Open UniversalProviderFormModal when universal preset is clicked - Pass initialPreset to auto-fill form when opened from add dialog - Add i18n keys for addSuccess/addFailed messages - Keep separate universal provider panel for management * refactor: move universal provider management to add dialog - Remove Layers button from main navigation header - Add 'Manage' button next to universal provider presets - Open UniversalProviderPanel from within add provider dialog - Add i18n keys for 'manage' in all locales * style: display universal provider presets on separate line - Move universal provider section to a new row with border separator - Add label '统一供应商:' to clarify the section * style: unify universal provider label style with preset label - Use FormLabel component for consistent styling - Add background to 'Manage' button matching preset buttons - Update icon size and button padding for consistency * 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. --------- Co-authored-by: Jason <farion1231@gmail.com> |

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. |
