# Phase 22: Log Flags Verification Report

**Phase Goal:** Users can filter, format, and customize git log output using the full range of commonly-used git log flags
**Verified:** 2026-01-21T13:05:11Z
**Status:** passed
**Re-verification:** No - initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | User running `git log --graph` sees ASCII commit graph | VERIFIED | cmd_log.py:143-145 - translates to `-G`, test_graph_flag passes |
| 2 | User running `git log --stat` sees diffstat with each commit | VERIFIED | cmd_log.py:147-149 - passes `--stat` through, test_stat_flag passes |
| 3 | User running `git log --author=<name>` sees only commits by that author | VERIFIED | cmd_log.py:155-162 - translates to `-u <pattern>`, both syntax tests pass |
| 4 | User running `git log --since='date'` sees only commits after that date | VERIFIED | cmd_log.py:185-191 - translates to `-d ">date"`, date filter tests pass |
| 5 | User running `git log --name-only` sees only filenames changed per commit | VERIFIED | cmd_log.py:201-203, template at line 36, test_name_only_flag passes |
| 6 | User running `git log --pretty=oneline` sees oneline format | VERIFIED | cmd_log.py:214-234, PRETTY_PRESETS dict at line 48, test_pretty_oneline passes |
| 7 | User running `git log -S` warns about pickaxe not being supported | VERIFIED | cmd_log.py:244-251, prints warning to stderr, test_pickaxe_S_warns passes |
| 8 | All 20 LOG requirements have E2E test coverage | VERIFIED | 45 tests across 14 test classes, each LOG-XX referenced in tests |
| 9 | Tests verify flag translation produces correct sl arguments | VERIFIED | TestLogDisplayFlags, TestLogFilterFlags, TestLogBehaviorFlags classes |
| 10 | Tests verify output format for --name-only, --name-status | VERIFIED | TestLogOutputFormatFlags class with test_name_only_flag, test_name_status_flag |
| 11 | Tests verify warning messages for unsupported -S/-G flags | VERIFIED | TestLogPickaxeWarnings class with test_pickaxe_S_warns, test_pickaxe_G_warns |

**Score:** 11/11 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `cmd_log.py` | Complete git log flag translation, 150+ lines | VERIFIED (312 lines) | Exists, substantive, wired via gitsl.py import |
| `tests/test_log.py` | E2E tests for all log flag requirements, 300+ lines | VERIFIED (458 lines) | Exists, 45 tests, uses run_gitsl helper |

### Key Link Verification

| From | To | Via | Status | Details |
|------|-----|-----|--------|---------|
| cmd_log.py | sl log | run_sl(sl_args) | WIRED | Line 312: `return run_sl(sl_args)` |
| gitsl.py | cmd_log.py | import and dispatch | WIRED | Line 15: `import cmd_log`, Line 77: `return cmd_log.handle(parsed)` |
| tests/test_log.py | cmd_log.py | run_gitsl calling handle() | WIRED | 48 calls to `run_gitsl(["log", ...])` |

| LOG-03: --patch/-p pass-through | SATISFIED | Implementation + 2 tests |
| LOG-04: --author -> -u | SATISFIED | Implementation + 2 tests |
| LOG-05: --grep -> -k | SATISFIED | Implementation + 2 tests |
| LOG-06: --no-merges pass-through | SATISFIED | Implementation + 1 test |
| LOG-07: --all pass-through | SATISFIED | Implementation + 1 test |
| LOG-08: --follow -> -f | SATISFIED | Implementation + 1 test |
| LOG-09: --since/--after -> -d | SATISFIED | Implementation + 2 tests |
| LOG-10: --until/--before -> -d | SATISFIED | Implementation + 2 tests |
| LOG-11: --name-only -> template | SATISFIED | Implementation + 1 test |

| LOG-13: --decorate -> template | SATISFIED | Implementation + 1 test |
| LOG-14: --pretty/--format -> -T | SATISFIED | Implementation + 6 tests |
| LOG-15: --first-parent -> revset | SATISFIED | Implementation + 1 test |
| LOG-16: --reverse -> revset | SATISFIED | Implementation + 1 test |
| LOG-17: -S pickaxe warning | SATISFIED | Implementation + 1 test |
| LOG-18: -G pickaxe warning | SATISFIED | Implementation + 1 test |
| LOG-19: -n/--max-count documented | SATISFIED | Implementation + 2 tests |
| LOG-20: --oneline documented | SATISFIED | Implementation + 1 test |

**Total:** 20/20 requirements satisfied

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| - | - | - | - | No anti-patterns found |

No TODO/FIXME/placeholder patterns found in cmd_log.py or tests/test_log.py.

### Human Verification Required

While automated verification passed, these items benefit from human testing:

#### 1. Visual Graph Output
**Test:** Run `git log --graph -5` in a repo with multiple branches
**Expected:** ASCII graph with proper alignment and visual structure
**Why human:** Graph aesthetics cannot be verified programmatically

#### 2. Date Format Edge Cases
**Test:** Run `git log --since="1 week ago"` 
**Expected:** Only commits from the last week appear
**Why human:** Relative date parsing may vary between sl versions

#### 3. Custom Format Output
**Test:** Run `git log --format=format:"%h - %an: %s"` 
**Expected:** Output matches format: `abc123 - John: Subject line`
**Why human:** Template translation needs visual verification

### Phase Summary

Phase 22 (Log Flags) has achieved its goal:

**Implementation Complete:**
- cmd_log.py extended from basic `-n`/`--oneline` to comprehensive 20-flag support
- 312 lines of substantive implementation
- Proper modular structure with helper functions and constant definitions
- All flag categories covered: display, filter, date, output format, complex

**Testing Complete:**
- tests/test_log.py with 45 E2E tests across 14 test classes
- Every LOG requirement has at least one dedicated test
- Both flag syntaxes tested where applicable (e.g., `--author=X` and `--author X`)
- Warning message tests for unsupported pickaxe flags

**Wiring Verified:**
- cmd_log.py properly imported and dispatched from gitsl.py
- Tests use run_gitsl helper that invokes actual command handling
- run_sl properly called with translated arguments
