+# Phase 1, Plan 1: Project Scaffolding Summary
+
+**Python project scaffolding with pyproject.toml (hatchling), ruff linting, pre-commit hooks, and src layout structure**
+
+## Performance
+
+- **Duration:** 8 min
+- **Started:** 2026-01-16T15:00:00Z
+- **Completed:** 2026-01-16T15:08:00Z
+- **Tasks:** 3
+- **Files created:** 7
+
+## Accomplishments
+- Created pyproject.toml with all dependencies and tool configurations
+- Configured pre-commit with ruff linting/formatting and standard hygiene hooks
+- Established src layout package structure matching SPEC.md architecture
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create pyproject.toml** - `39b1781` (build)
+2. **Task 2: Create pre-commit configuration** - `5856e6b` (chore)
+3. **Task 3: Create src layout and package structure** - `44e2322` (feat)
+
+**Plan metadata:** (pending)
+
+## Files Created/Modified
+- `pyproject.toml` - Project metadata, dependencies, ruff/pytest config
+- `.pre-commit-config.yaml` - Pre-commit hooks configuration
+- `src/moai/__init__.py` - Package root with __version__
+- `src/moai/bot/__init__.py` - Bot subpackage marker
+- `src/moai/bot/handlers/__init__.py` - Handlers subpackage marker
+- `src/moai/core/__init__.py` - Core subpackage marker
+- `tests/__init__.py` - Test package marker
+
+## Decisions Made
+- Used hatchling with explicit `packages = ["src/moai"]` for src layout (required for editable install)
+- Selected ruff-pre-commit v0.14.13 (latest stable as of 2026-01-16)
+- Used pre-commit-hooks v5.0.0 for standard hooks
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Added hatch build configuration for src layout**
+- **Found during:** Task 1 (pyproject.toml creation)
+- **Issue:** Hatchling couldn't find package without explicit src layout config
+- **Fix:** Added `[tool.hatch.build.targets.wheel] packages = ["src/moai"]`
+- **Files modified:** pyproject.toml
+- **Verification:** pip install -e ".[dev]" succeeds
+- **Committed in:** 39b1781 (Task 1 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (blocking issue), 0 deferred
+**Impact on plan:** Auto-fix was necessary for hatchling to work with src layout. No scope creep.
+
+## Issues Encountered
+None - all tasks completed successfully after the hatchling configuration fix.
+
+## Next Phase Readiness
+- Project scaffolding complete, ready for Phase 1 Plan 2 (database models)
+- All tooling in place: ruff, pre-commit, pytest
+- Package importable and version accessible
