- Move blocking usage queries and core lifecycle operations to background
workers, limit concurrency, and prevent overlapping core operations
- Coalesce statistics refreshes and consolidate category aggregations,
reducing unfiltered analysis queries from 11 to 4
- Cache bundled model prices, reuse management API connections, and reduce
redundant checks in the usage collector
- Throttle download progress and guide positioning updates, and avoid
redundant renders when core status is unchanged
- Bound and coalesce configuration watcher events, and reuse a single
model catalog refresh worker
- Stop scheduling remaining health checks when the dialog closes and
limit backend health-check concurrency
- Replace overlapping OAuth polling with sequential requests, retry
backoff, timeouts, and stale callback protection
- Add regression tests and a statistics benchmark script, and move
performance verification documentation to agent_docs
- Align fallback defaults and instruction structure with upstream Codex while preserving Fast availability for all models
- Stop forcing fallback reasoning levels or inferring original-image support
- Sync managed catalogs on model refresh, configuration changes, and every 30 seconds
- Remove unavailable models, replace missing defaults, and handle empty-list recovery
- Preserve existing configuration on request failures or invalid responses
- Serialize refreshes, update UI model lists, and preserve backups across restarts
- Add regression coverage for fallback compatibility, stale-model cleanup, and configuration recovery
- split Tauri business logic out of main.rs by domain
- separate agent and core configuration submodules
- organize Rust tests by feature with shared test support
- split frontend locale resources
