- Added test coverage for auto-compaction entry warning attribution during dead-end scenarios.
- Verified automatic continuation and warning suppression when image-drop recovery successfully clears context pressure.
- Mocked session context usage and image-drop functionality to simulate high-usage state recovery.
- Enabled persistence of dangling tool calls during transcript rebuilds by adding `keepDanglingToolCalls` configuration.
- Integrated `seal()` logic for pending tool blocks to properly finalize history during idle session states.
- Enhanced UI helpers and session context to preserve assistant turns during streaming or mid-turn rebuilds.
- Added comprehensive unit and integration tests to verify correct tool call tracking and transcript integrity.
Avoided reattaching snapcompact archive image blocks when rebuilding collapsed transcript contexts so live TUI resumes do not retain archived frames.
Added regression coverage for collapsed transcripts while preserving full transcript and provider context frame reattachment.
