Phase 1 Plan 1: State Persistence Layer Summary

SessionState dataclass with atomic saves, backup rotation, and automatic fallback for crash-safe persistence

Performance

• Duration: 7 min
• Started: 2026-03-10T16:32:46Z
• Completed: 2026-03-10T16:39:55Z
• Tasks: 4
• Files modified: 5

Accomplishments

• SessionState dataclass with all required fields for session metadata
• Atomic save_state() using tempfile + os.replace pattern
• load_state() with schema validation and automatic backup fallback
• StateManager class providing clean interface with workspace path resolution

Task Commits

Each task was committed atomically:

1. Task 1: Create state schema with dataclasses - 9ef5733 (feat)
2. Task 2: Implement atomic state save with backup rotation - 8e0c973 (feat)
3. Task 3: Implement state load with validation and fallback - b221c5a (feat)
4. Task 4: Create StateManager class with workspace path resolution - b2175b3 (feat)

Files Created/Modified

• src/gsd_openclaw/state_manager.py - SessionState dataclass, save_state, load_state, StateManager
• src/gsd_openclaw/__init__.py - Package exports
• tests/test_state_manager.py - 25 comprehensive tests
• tests/conftest.py - Added tmp_state_dir and sample_state fixtures
• pyproject.toml - Python package configuration

Decisions Made

• Atomic write pattern: Use tempfile.mkstemp in target directory, then os.replace for POSIX-atomic rename
• Backup strategy: Single backup file (state.json.bak), rotated on each save
• Validation: Schema version must be "1.0", required fields: session_id, project_name, tmux_session_name
• Fallback behavior: On JSON or validation errors, automatically try backup file

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None - all tasks completed smoothly following TDD approach.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• State persistence layer complete and tested
• Ready for Phase 1 Plan 02 (tmux session management)
• StateManager can be imported by other components for state access
