# Phase 4: Direct Command Mappings Verification Report

**Phase Goal:** Simple git commands translate directly to sl equivalents
**Verified:** 2026-01-18T03:55:00Z
**Status:** passed
**Re-verification:** No - initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | git status runs sl status and shows output | VERIFIED | Existing cmd_status.py handler, tested in Phase 3 |
| 2 | git log runs sl log and shows output | VERIFIED | cmd_log.py exists (13 lines), wired in gitsl.py line 60-61, 3 E2E tests pass |
| 3 | git diff runs sl diff and shows output | VERIFIED | cmd_diff.py exists (13 lines), wired in gitsl.py line 63-64, 3 E2E tests pass |
| 4 | git init runs sl init and creates repo | VERIFIED | cmd_init.py exists (13 lines), wired in gitsl.py line 66-67, 2 E2E tests pass (including .hg directory check) |
| 5 | git rev-parse --short HEAD returns current commit hash | VERIFIED | cmd_rev_parse.py exists (33 lines), wired in gitsl.py line 69-70, 5 E2E tests pass (7-char hex output verified) |

**Score:** 5/5 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `cmd_log.py` | Handler for git log command | VERIFIED | 13 lines, exports handle(), uses run_sl() |
| `cmd_diff.py` | Handler for git diff command | VERIFIED | 13 lines, exports handle(), uses run_sl() |
| `cmd_init.py` | Handler for git init command | VERIFIED | 13 lines, exports handle(), uses run_sl() |
| `cmd_rev_parse.py` | Handler for git rev-parse command | VERIFIED | 33 lines, exports handle(), uses subprocess with capture_output, truncates to 7 chars |
| `tests/test_cmd_log.py` | E2E tests for log command | VERIFIED | 46 lines, 3 tests (2 basic, 1 exit code) |
| `tests/test_cmd_diff.py` | E2E tests for diff command | VERIFIED | 46 lines, 3 tests (2 basic, 1 exit code) |
| `tests/test_cmd_init.py` | E2E tests for init command | VERIFIED | 38 lines, 2 tests (repo creation, .hg directory) |
| `tests/test_cmd_rev_parse.py` | E2E tests for rev-parse command | VERIFIED | 53 lines, 5 tests (7-char, hex, order, exit codes) |
| `tests/conftest.py` (sl_repo fixtures) | Sapling repo fixtures | VERIFIED | sl_repo and sl_repo_with_commit fixtures added (lines 141-173) |

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| gitsl.py | cmd_log.py | import and dispatch | WIRED | line 14: `import cmd_log`, line 60-61: dispatch |
| gitsl.py | cmd_diff.py | import and dispatch | WIRED | line 15: `import cmd_diff`, line 63-64: dispatch |
| gitsl.py | cmd_init.py | import and dispatch | WIRED | line 16: `import cmd_init`, line 66-67: dispatch |
| gitsl.py | cmd_rev_parse.py | import and dispatch | WIRED | line 17: `import cmd_rev_parse`, line 69-70: dispatch |
| cmd_log.py | common.py | run_sl() | WIRED | line 3: `from common import ParsedCommand, run_sl` |
| cmd_diff.py | common.py | run_sl() | WIRED | line 3: `from common import ParsedCommand, run_sl` |
| cmd_init.py | common.py | run_sl() | WIRED | line 3: `from common import ParsedCommand, run_sl` |
| cmd_rev_parse.py | sl whereami | subprocess.run | WIRED | line 16-20: subprocess.run(["sl", "whereami"], capture_output=True) |

### Requirements Coverage

| Requirement | Status | Evidence |
|-------------|--------|----------|
| CMD-01: git status -> sl status | SATISFIED | Already implemented in Phase 3 (cmd_status.py) |
| CMD-04: git log -> sl log | SATISFIED | cmd_log.py + E2E tests pass |
| CMD-05: git diff -> sl diff | SATISFIED | cmd_diff.py + E2E tests pass |
| CMD-06: git init -> sl init | SATISFIED | cmd_init.py + E2E tests, .hg directory created |
| CMD-07: git rev-parse --short HEAD -> sl whereami | SATISFIED | cmd_rev_parse.py, returns 7-char hex hash |

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| gitsl.py | 73 | `[STUB] Would process` | Info | Expected - fallback for unimplemented commands |

No blocking anti-patterns found. The STUB message is intentional fallback behavior for commands not yet implemented.

### Test Results

All 53 tests pass:
- Phase 4 specific tests: 13 tests pass
  - test_cmd_log.py: 3 tests
  - test_cmd_diff.py: 3 tests
  - test_cmd_init.py: 2 tests
  - test_cmd_rev_parse.py: 5 tests
- No regressions in existing tests

### Manual Verification Performed

Commands tested manually against actual Sapling repository:

1. **git init**: Creates .hg directory successfully
2. **git log**: Shows commit history in Sapling format
3. **git diff**: Shows unified diff for modified files
4. **git rev-parse --short HEAD**: Returns exactly 7 hex characters (e.g., "c62d1fa")
5. **git status**: Shows modified files (M file.txt)

Debug mode verified for all commands:
- `GITSL_DEBUG=1 gitsl log` -> `[DEBUG] Would execute: sl log`
- `GITSL_DEBUG=1 gitsl diff` -> `[DEBUG] Would execute: sl diff`
- `GITSL_DEBUG=1 gitsl init` -> `[DEBUG] Would execute: sl init`
- `GITSL_DEBUG=1 gitsl rev-parse --short HEAD` -> `[DEBUG] Would execute: sl rev-parse --short HEAD`

### Human Verification Required

None. All must-haves verified programmatically through:
1. Artifact existence and substantiveness checks
2. Key link verification (imports and dispatches)
3. E2E test execution (13 tests pass)
4. Manual command execution verification

## Summary

Phase 4 goal "Simple git commands translate directly to sl equivalents" is **achieved**.

All 5 observable truths verified:
- git log, git diff, git init translate correctly to sl equivalents
- git rev-parse --short HEAD returns 7-character hex hash via sl whereami
- All handlers follow established patterns (passthrough or capture_output)
- All E2E tests pass (13 new tests, 53 total)
- No regressions in existing functionality

Requirements CMD-01, CMD-04, CMD-05, CMD-06, CMD-07 are all satisfied.
