# Quick Task 2: Convert Python Scripts to uv Scripts Summary

**PEP 723 inline metadata on setup_ducklake.py and test_ducklake.py with uv run Justfile recipes, tracked fuzz/Cargo.lock, gitignored dbt/**

## Performance

- **Duration:** 2 min
- **Started:** 2026-02-28T00:22:14Z
- **Completed:** 2026-02-28T00:24:19Z
- **Tasks:** 2
- **Files modified:** 5

## Accomplishments
- Both Python scripts (configure/setup_ducklake.py, test/integration/test_ducklake.py) now declare duckdb dependency via PEP 723 inline metadata
- Justfile setup-ducklake and test-iceberg recipes use `uv run` instead of hardcoded venv path
- fuzz/Cargo.lock committed for reproducible fuzz builds
- dbt/ directory gitignored (reference material, not project code)

## Task Commits

Each task was committed atomically:

1. **Task 1: Add PEP 723 inline metadata to Python scripts and update justfile** - `ab4bf0c` (feat)
2. **Task 2: Gitignore dbt/ and commit fuzz/Cargo.lock** - `bb1309f` (chore)

## Files Created/Modified
- `configure/setup_ducklake.py` - Added PEP 723 inline script metadata declaring duckdb dependency
- `test/integration/test_ducklake.py` - Added PEP 723 inline script metadata declaring duckdb dependency
- `Justfile` - Updated setup-ducklake and test-iceberg recipes to use `uv run`, updated comment
- `.gitignore` - Added dbt/ exclusion
- `fuzz/Cargo.lock` - Newly tracked (was untracked)

## Decisions Made
- Rewrote Justfile comment referencing `configure/venv` path to use generic wording ("its Python venv") so zero configure/venv references remain in Justfile

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Justfile comment still referenced configure/venv**
- **Found during:** Task 1 verification
- **Issue:** Plan verification requires zero `configure/venv` references in Justfile; a comment on line 56 still contained the literal path
- **Fix:** Rewrote comment from "installed by `make configure` into configure/venv" to "installed by `make configure` into its Python venv"
- **Files modified:** Justfile
- **Verification:** `grep 'configure/venv' Justfile` returns nothing
- **Committed in:** ab4bf0c (Task 1 commit)

---

**Total deviations:** 1 auto-fixed (1 blocking)
**Impact on plan:** Minor comment rewording to satisfy zero-venv-reference verification. No scope creep.

## Issues Encountered
None.

## User Setup Required
None - no external service configuration required. Users need `uv` installed to run the scripts (standard Python tooling).

## Next Phase Readiness
N/A - standalone quick task, no follow-on phases.
