- Implemented mutable session titles with audit tracking, including storage persistence for SQL and Redis backends.
- Added comprehensive session management features such as idle recap triggers, incremental subagent yield submissions, and automated title refreshing.
- Enhanced task tracking in the TodoTool with progress prioritization and improved session cleanup logic.
- Introduced citation tag handling for OpenAI-compatible source markers and improved edit parsing.
- Added session-domain modules and exports for session-entries, context, listing, loader, and migrations.
- Changed persistence to async append writes plus writeTextAtomic, removing sync line APIs.
- Added compaction-aware session context rebuild with dangling tool-call cleanup.
- Added resumable session resolution with status inference, id/stem/suffix matching, and backup recovery.
- Added `IndexedSessionStorage` with `SessionStorageBackend` for index-based storage reads.
- Removed `readTextSync` from the public `SessionStorage` API and sync backends.
- Changed Redis and SQL backends to warm `{size, mtimeMs}` metadata and read via `readTextSlices`.
- Added per-path write queues and `drain()` to serialize operations and surface first failures.
- Column truncation is now applied to a cloned array so `collectedLines` retains on-disk content for snapshot recording.
- Snapshots bound to hashline TAGs now hold the original file text, preventing hash-mismatch failures on subsequent edits to files with long lines.
- Added regression tests covering full-file, range, multi-range reads and a live edit-after-read scenario.
