# Phase 7: Log Output Emulation Verification Report

**Phase Goal:** Log output supports git's format options
**Verified:** 2026-01-18T14:30:00Z
**Status:** passed
**Re-verification:** No - initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | git log --oneline outputs hash and subject per line | VERIFIED | cmd_log.py:64 uses `-T "{node|short} {desc|firstline}\n"` template; TestLogOneline passes |
| 2 | git log -N limits output to N commits | VERIFIED | cmd_log.py:67 uses `-l N`; TestLogLimit (4 tests) all pass |
| 3 | git log --oneline -5 combines both flags correctly | VERIFIED | cmd_log.py handles both flags independently; TestLogCombined passes |
| 4 | Basic git log (no flags) still works unchanged | VERIFIED | TestLogBasic::test_log_succeeds_in_repo_with_commit passes |

**Score:** 4/4 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `cmd_log.py` | Flag translation for --oneline and -N | VERIFIED | 71 lines, contains ONELINE_TEMPLATE, parses --oneline/-N/-n N/-nN/--max-count=N |
| `tests/conftest.py` | sl_repo_with_commits fixture | VERIFIED | 192 lines, fixture at lines 176-192, creates 10 commits |
| `tests/test_cmd_log.py` | E2E tests for log flags | VERIFIED | 124 lines, contains TestLogOneline, TestLogLimit, TestLogCombined classes |

### Artifact Three-Level Verification

#### cmd_log.py
- **Level 1 (Exists):** YES - file exists (71 lines)
- **Level 2 (Substantive):** YES
  - Contains ONELINE_TEMPLATE constant (line 9)
  - Contains flag parsing for 5 formats (--oneline, -N, -n N, -nN, --max-count=N)
  - No TODO/FIXME/placeholder patterns found
  - Has exports (handle function)
- **Level 3 (Wired):** YES
  - Imported in gitsl.py (line 14)
  - Called for "log" command (gitsl.py line 63)

#### tests/conftest.py
- **Level 1 (Exists):** YES - file exists (192 lines)
- **Level 2 (Substantive):** YES
  - Contains sl_repo_with_commits fixture (lines 176-192)
  - Creates 10 files with 10 commits in a loop
  - No stub patterns
- **Level 3 (Wired):** YES
  - Fixture used by test_cmd_log.py tests (sl_repo_with_commits parameter)

#### tests/test_cmd_log.py
- **Level 1 (Exists):** YES - file exists (124 lines)
- **Level 2 (Substantive):** YES
  - Contains 10 test methods
  - TestLogOneline class (lines 48-67)
  - TestLogLimit class (lines 70-103)
  - TestLogCombined class (lines 106-124)
  - No stub patterns
- **Level 3 (Wired):** YES
  - Tests run via pytest
  - Uses run_gitsl from conftest to test actual CLI

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| cmd_log.py | sl log | run_sl with -T and -l flags | WIRED | run_sl imported (line 4), -T at line 64, -l at line 67, run_sl called at line 71 |
| tests/test_cmd_log.py | cmd_log.py | run_gitsl log --oneline | WIRED | 8 test calls use run_gitsl(["log", "--oneline", ...]) |

### Requirements Coverage

| Requirement | Status | Evidence |
|-------------|--------|----------|
| FLAG-04: git log --oneline emulates git oneline format via sl template | SATISFIED | ONELINE_TEMPLATE uses `{node|short} {desc|firstline}` |
| FLAG-05: git log -N limits output to N commits via sl -l N | SATISFIED | limit flag translated to `-l N` in cmd_log.py |

### Test Results

All 10 tests pass:

```
tests/test_cmd_log.py::TestLogBasic::test_log_succeeds_in_repo_with_commit PASSED
tests/test_cmd_log.py::TestLogBasic::test_log_shows_output PASSED
tests/test_cmd_log.py::TestLogExitCodes::test_log_fails_in_non_repo PASSED
tests/test_cmd_log.py::TestLogOneline::test_oneline_returns_hash_and_subject PASSED
tests/test_cmd_log.py::TestLogLimit::test_limit_with_dash_n PASSED
tests/test_cmd_log.py::TestLogLimit::test_limit_with_dash_n_space PASSED
tests/test_cmd_log.py::TestLogLimit::test_limit_with_dash_n_attached PASSED
tests/test_cmd_log.py::TestLogLimit::test_limit_with_max_count PASSED
tests/test_cmd_log.py::TestLogCombined::test_oneline_with_limit_either_order PASSED
tests/test_cmd_log.py::TestLogCombined::test_limit_greater_than_available PASSED
```

### Anti-Patterns Found

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

No anti-patterns detected. No TODO/FIXME/placeholder patterns in any modified files.

### Human Verification Required

None. All truths are verifiable programmatically through the E2E tests:
- Test output format verification (hash validation, line count)
- Test combined flag behavior
- Test passthrough behavior
