## New Features

- Added `thread/compact` to the v2 app-server API as an async trigger RPC, so clients can start compaction immediately and track completion separately. (#10445)
- Added websocket-side rate limit signaling via a new `codex.rate_limits` event, with websocket parity for ETag/reasoning metadata handling. (#10324)
- Enabled `unified_exec` on all non-Windows platforms. (#10641)
- Constrained requirement values now include source provenance, enabling source-aware config debugging in UI flows like `/debug-config`. (#10568)

## Bug Fixes
- Fixed `Esc` handling in the TUI `request_user_input` overlay: when notes are open, `Esc` now exits notes mode instead of interrupting the session. (#10569)
- Thread listing now queries the state DB first (including archived threads) and falls back to filesystem traversal only when needed, improving listing correctness and resilience. (#10544)
- Fixed thread path lookup to require that the resolved file actually exists, preventing invalid thread-id resolutions. (#10618)
- Dynamic tool injection now runs in a single transaction to avoid partial state updates. (#10614)
- Refined `request_rule` guidance used in approval-policy prompting to correct rule behavior. (#10379, #10598)

## Documentation
- Updated app-server docs for `thread/compact` to clarify its asynchronous behavior and thread-busy lifecycle. (#10445)
- Updated TUI docs to match the mode-specific `Esc` behavior in `request_user_input`. (#10569)

## Chores
- Migrated state DB helpers to a versioned SQLite filename scheme and cleaned up legacy state files during runtime initialization. (#10623)
- Expanded runtime telemetry with websocket timing metrics and simplified internal metadata flow in core client plumbing. (#10577, #10589)
