- 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 a focused-agent left-key input listener that consumes double left taps when the input is empty.
- Routed focused session left-tap behavior through #handleFocusedLeftTap so it matches the Esc-style unfocus timing.
- Updated tests/fixtures for the new listener flow and refreshed a hashline block-edit error assertion.
- Added a SessionFocusController to switch transcript and input context between main and subagent sessions.
- Added agent-hub Enter activation and double-left return behavior for focused local agents.
- Added view-session-based event and render logic to avoid stale focus-session state.
- Added status-line focused agent display with ghost icon and focused-mode border dimming.
- Enabled resume picker to preload sessions and toggle folder/all scope with Tab.
- Enabled resume flow to fall back to all-project sessions and switch cwd on resume.
- Added centralized applyCwdChange to refresh caches, commands, and UI after cwd updates.
- Updated session restoration to adopt restored session cwd and sessionDir when present.
- Session metadata now stores on-disk size bytes, populated from file stats when collecting sessions.
- The session selector metadata line now renders file size using formatBytes instead of message counts.
- Session test fixtures were updated with the new size property so they match the revised SessionInfo shape.
- Updated selector-controller session-delete test mocks to include updateEditorBorderColor.
- Extended session deletion expectations to verify updateEditorBorderColor is called.
- Refined a long chunk-mode test string assertion to multiline formatting for readability.
- Extracted OpenAI compatibility detection and resolution logic into dedicated `openai-completions-compat` module.
- Refactored `detectCompat()` and `getCompat()` to delegate to new compat module functions with simplified conditional logic.
- Fixed OAuth redirect URI validation to preserve exact configured values without trailing slash normalization.
- Improved session deletion to return boolean status and display error messages in UI instead of silently failing.
- Added `/session delete` command with Delete key support and confirmation dialogs for session management.
