- Added git branch isolation for autoresearch sessions with automatic branch creation, reuse, and worktree safety checks.
- Added scope definition sections (Files in Scope, Off Limits, Constraints) to autoresearch template for explicit session boundaries.
- Added keybinding matcher utilities for consistent escape/cancel key handling across interactive components.
- Added ASI metadata validation (hypothesis and rollback context) in log_experiment tool for experiment tracking.
