# Phase 6: Status Output Emulation Verification Report

**Phase Goal:** Status output matches git's format exactly for tooling compatibility
**Verified:** 2026-01-18T04:58:56Z
**Status:** PASSED
**Re-verification:** No - initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | git status --porcelain outputs 2-char XY codes matching git format | VERIFIED | `transform_to_porcelain()` function at line 46 transforms sl output using `SL_TO_GIT_STATUS` mapping dict |
| 2 | git status --short outputs same format as --porcelain | VERIFIED | Line 87: `'--short' in parsed.args` triggers same `transform_to_porcelain()` code path |
| 3 | Untracked file shows as ?? filename | VERIFIED | Line 16: `'?': '??'` in SL_TO_GIT_STATUS mapping |
| 4 | Modified file shows as " M" filename (space + M) | VERIFIED | Line 13: `'M': ' M'` in SL_TO_GIT_STATUS mapping |
| 5 | Added file shows as "A " filename (A + space) | VERIFIED | Line 14: `'A': 'A '` in SL_TO_GIT_STATUS mapping |
| 6 | Removed file shows as "D " filename (D + space) | VERIFIED | Line 15: `'R': 'D '` in SL_TO_GIT_STATUS mapping |
| 7 | Missing file shows as " D" filename (space + D) | VERIFIED | Line 17: `'!': ' D'` in SL_TO_GIT_STATUS mapping |
| 8 | git status (no flags) still passthroughs to sl status | VERIFIED | Lines 108-109: `return run_sl(['status'] + parsed.args)` when no transform flags detected |
| 9 | Clean repo with --porcelain outputs empty string | VERIFIED | Lines 74-76: only appends newline if lines exist, returns `''` for empty output |

**Score:** 9/9 truths verified

### Required Artifacts

| Artifact | Expected | Exists | Substantive | Wired | Status |
|----------|----------|--------|-------------|-------|--------|
| `cmd_status.py` | Handler with porcelain/short output transformation, contains `transform_to_porcelain` | YES (109 lines) | YES - Contains SL_TO_GIT_STATUS mapping, parse_sl_status_line(), transform_to_porcelain(), handle() | YES - Imported in gitsl.py line 13, dispatched at line 60 | VERIFIED |
| `tests/test_status_porcelain.py` | E2E tests for porcelain format (min 80 lines) | YES (168 lines) | YES - 11 test methods covering all status scenarios | YES - Uses run_gitsl from conftest.py, sl_repo fixtures | VERIFIED |

**Artifact Details:**

#### cmd_status.py (109 lines)
- **Level 1 (Exists):** VERIFIED - File exists at `/Users/vmakaev/NonWork/gitsl/cmd_status.py`
- **Level 2 (Substantive):** VERIFIED
  - Contains `SL_TO_GIT_STATUS` dict with 6 status code mappings (lines 12-19)
  - Contains `parse_sl_status_line()` function (lines 22-43)
  - Contains `transform_to_porcelain()` function (lines 46-76)
  - Contains `handle()` function with flag detection (lines 79-109)
  - No TODO/FIXME/placeholder patterns found
  - No empty returns or stub patterns
- **Level 3 (Wired):** VERIFIED
  - Imported: `import cmd_status` in gitsl.py line 13
  - Called: `return cmd_status.handle(parsed)` in gitsl.py line 60
  - Uses `subprocess.run` with `capture_output=True` (lines 94-98)
  - Uses `run_sl` from common.py for passthrough (line 109)

#### tests/test_status_porcelain.py (168 lines)
- **Level 1 (Exists):** VERIFIED - File exists at `/Users/vmakaev/NonWork/gitsl/tests/test_status_porcelain.py`
- **Level 2 (Substantive):** VERIFIED
  - 11 test methods across 9 test classes
  - Tests: untracked, added, modified, removed, missing, clean repo, mixed states, --short, -s, passthrough
  - Tests use exact assertions: `assert result.stdout == "?? untracked.txt\n"`
  - No TODO/FIXME/placeholder patterns found
- **Level 3 (Wired):** VERIFIED
  - Imports `run_gitsl` from conftest.py
  - Uses `sl_repo` and `sl_repo_with_commit` fixtures
  - Uses `run_command` from helpers.commands
  - Syntax validated with Python AST parser

### Key Link Verification

| From | To | Via | Status | Evidence |
|------|----|-----|--------|----------|
| cmd_status.py | subprocess | capture_output pattern | WIRED | Line 96: `capture_output=True` in subprocess.run call |
| cmd_status.py | common.py | run_sl for passthrough | WIRED | Line 109: `return run_sl(['status'] + parsed.args)` |
| gitsl.py | cmd_status.py | import + dispatch | WIRED | Line 13: import, Line 60: dispatch to handle() |
| test_status_porcelain.py | conftest.py | run_gitsl | WIRED | Line 12: `from conftest import run_gitsl` |
| test_status_porcelain.py | helpers.commands | run_command | WIRED | Line 13: `from helpers.commands import run_command` |

### Requirements Coverage

| Requirement | Status | Evidence |
|-------------|--------|----------|
| FLAG-01: git status --porcelain emulates exact git porcelain format | SATISFIED | transform_to_porcelain() produces 2-char XY codes with proper spacing |
| FLAG-02: git status --short emulates git short format | SATISFIED | --short flag triggers same transform_to_porcelain() as --porcelain |

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| (none) | - | - | - | - |

No anti-patterns detected:
- No TODO/FIXME/placeholder comments in cmd_status.py
- No TODO/FIXME/placeholder comments in test_status_porcelain.py
- No empty returns (`return null`, `return {}`, `return []`)
- No console.log-only implementations
- All functions have real implementations

### Human Verification Required

| # | Test | Expected | Why Human |
|---|------|----------|-----------|
| 1 | Run `git status --porcelain` in sl repo with modified file | Output: ` M filename` (space + M + space + filename) | Verify exact byte format matches git (no extra whitespace or characters) |
| 2 | Test with external workflow | External tool parses status output without errors | Integration test with actual tooling that depends on format |

These items require human verification because:
1. Exact byte-for-byte format matching needs visual inspection with `cat -A` or similar
2. Integration with external tools requires running the actual workflow

### Test Coverage Summary

11 tests covering:
- `TestPorcelainUntracked`: 2 tests (single file, multiple files)
- `TestPorcelainAdded`: 1 test
- `TestPorcelainModified`: 1 test
- `TestPorcelainRemoved`: 1 test
- `TestPorcelainMissing`: 1 test
- `TestPorcelainCleanRepo`: 1 test
- `TestPorcelainMixedStates`: 1 test
- `TestShortFlag`: 2 tests (--short, -s)
- `TestNormalStatusPassthrough`: 1 test

## Summary

**Phase 6 goal ACHIEVED.** All 9 must-haves verified:

1. **Code Implementation:** `cmd_status.py` correctly transforms sl status output to git porcelain format
2. **Status Code Mapping:** All required mappings present (M->" M", A->"A ", R->"D ", ?->"??", !->" D")
3. **Flag Detection:** --porcelain, --short, and -s flags correctly trigger transformation
4. **Passthrough:** Normal status command correctly passes through to sl status
5. **Test Coverage:** 11 E2E tests cover all status scenarios
6. **Requirements:** FLAG-01 and FLAG-02 are satisfied
