# Quick Task 7: Fix rustfmt CI Failure Summary

**Auto-formatted vector_reference_test.rs and added cargo-fmt pre-commit hook to catch future formatting issues locally**

## Performance

- **Duration:** 2 min
- **Started:** 2026-03-03T13:05:52Z
- **Completed:** 2026-03-03T13:07:41Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments
- Fixed all rustfmt formatting issues in tests/vector_reference_test.rs (line-length, indentation, call chain formatting across ~12 diff blocks)
- Added local cargo-fmt pre-commit hook so formatting issues are caught before push
- Verified cargo fmt --check exits 0 and all 42 tests pass (36 unit + 5 integration + 1 doc)

## Task Commits

Each task was committed atomically:

1. **Task 1: Run cargo fmt and verify all checks pass** - `8f01f7a` (style)
2. **Task 2: Add cargo fmt check to pre-commit hooks** - `ade0433` (chore)

## Files Created/Modified
- `tests/vector_reference_test.rs` - Auto-formatted by cargo fmt (line wrapping, argument indentation, assert macro formatting)
- `.pre-commit-config.yaml` - Added local cargo-fmt hook entry

## Decisions Made
- Used `repo: local` hook type with `language: system` for cargo fmt -- no external pre-commit repo needed since cargo is already installed locally

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None.

## User Setup Required
None - no external service configuration required.
