# Changelog

## 2026-02-16

### Refactor Results

- Modularized CLI command implementations:
  - Added `src/vlm/commands/parse.py`
  - Added `src/vlm/commands/enrich.py`
  - Added `src/vlm/commands/execute.py`
  - Refactored `src/vlm/cli.py` to delegate `parse`, `enrich`, `execute`, and `rollback` to command modules

- Unified I/O layer for JSON handling:
  - Added `load_json_file`, `save_json_file`, `save_analysis_json` in `src/vlm/io.py`
  - Updated analyze/enrich paths to use unified I/O entry points

- Parser/config consistency improvements:
  - Added shared `DEFAULT_VIDEO_EXTENSIONS` in `src/vlm/config.py`
  - Updated `src/vlm/parser.py` to use the shared config constant instead of local hardcoded defaults

- Execution reliability hardening:
  - Updated `src/vlm/executor.py` transaction logging to fail gracefully when `~/.vlm` is not writable (warn + continue)

- Test stability improvements:
  - Standardized test timestamps to timezone-aware UTC (`datetime.now(timezone.utc)`)
  - Added missing `timezone` imports where required

### Verification

- Full test suite passed after refactor:
  - `477 passed`

### Documentation Sync

- Updated repository documentation set to match the refactor baseline:
  - Core docs: `README.md`, `AGENTS.md`, `CLAUDE.md`, `GEMINI.md`
  - Skill docs: `skills/vlm-library-workflow/SKILL.md` and all references under `skills/vlm-library-workflow/references/`
  - Legacy review/plan docs now explicitly marked as historical snapshots and redirected to `CHANGELOG.md` as the current source of truth
