# Dependency graph
requires:
  - phase: 04-direct-command-mappings
    provides: Basic command handler pattern with ParsedCommand
provides:
  - Porcelain output transformation for status command
  - Status code mapping (sl -> git XY format)
  - E2E tests for format verification
affects: [07-diff-format-support, any-phase-needing-git-status-parsing]

# Tech tracking
tech-stack:
  added: []
  patterns: [capture_output pattern for output transformation, status code mapping dict]

key-files:
  created: [tests/test_status_porcelain.py]
  modified: [cmd_status.py]

key-decisions:
  - "Status code mapping: sl M -> git ' M' (space+M), sl A -> git 'A ' (A+space)"
  - "Use capture_output=True pattern from cmd_rev_parse.py for output transformation"
  - "Empty output for clean repo (no trailing newline)"

patterns-established:
  - "SL_TO_GIT_STATUS mapping dict for sl->git status code translation"
  - "transform_to_porcelain function for output format conversion"
  - "Porcelain test pattern: exact byte-for-byte format verification"

# Phase 6 Plan 1: Porcelain Status Output Summary

**Implemented --porcelain/--short/-s flags for git status with sl->git status code mapping**

## Performance

- **Duration:** 4 min
- **Started:** 2026-01-18T04:51:39Z
- **Completed:** 2026-01-18T04:55:07Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments
- Status command transforms sl output to git porcelain format when --porcelain/--short/-s flags used
- Status code mapping: untracked(??), added(A ), modified( M), removed(D ), missing( D)
- Normal status command still passthroughs to sl status
- 11 E2E tests covering all status code scenarios

## Task Commits

Each task was committed atomically:

1. **Task 1: Enhance cmd_status.py with porcelain output transformation** - `f7a6e96` (feat)
2. **Task 2: Create E2E tests for porcelain status format** - `ef8ebc8` (test)

## Files Created/Modified
- `cmd_status.py` - Handler with porcelain/short output transformation, SL_TO_GIT_STATUS mapping
- `tests/test_status_porcelain.py` - E2E tests for porcelain format (168 lines)

## Decisions Made
- Used existing capture_output pattern from cmd_rev_parse.py
- Status code mapping based on sl's no-staging-area model:
  - sl M (modified) -> git " M" (unstaged modification)
  - sl A (added) -> git "A " (staged addition)
  - sl R (removed) -> git "D " (staged deletion)
  - sl ! (missing) -> git " D" (working tree deletion)
- Empty string output for clean repos (no trailing newline)

## Deviations from Plan
None - plan executed exactly as written.

## Issues Encountered
None

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

## Next Phase Readiness
- Status output emulation complete for --porcelain, --short, -s flags
- Ready for additional status options (--branch, etc.) if needed
- Pattern established for other output transformation commands
