# Phase 27: Grep and Blame Flags Verification Report

**Phase Goal:** Users can search code and view file history with the full range of grep and blame flags
**Verified:** 2026-01-22
**Status:** passed
**Re-verification:** No -- initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | User can search with git grep flags and get correct results | VERIFIED | cmd_grep.py handles all 14 GREP flags (line 57-135); 26 tests pass |
| 2 | User can use git blame flags for enhanced annotation output | VERIFIED | cmd_blame.py handles all 7 BLAM flags (line 42-91); 12 tests pass |
| 3 | User gets helpful warnings for unsupported flags | VERIFIED | Warnings for GREP-04,-10,-12,-13 and BLAM-03,-04,-05,-06; tests verify warning output |
| 4 | git grep -v correctly inverts match (translated to sl -V) | VERIFIED | cmd_grep.py:79-80 translates -v to -V; test_grep_invert_match_v passes |
| 5 | git blame -b correctly ignores space changes (translated to sl --ignore-space-change) | VERIFIED | cmd_blame.py:49-50 translates -b to --ignore-space-change; test_blame_ignore_space_change_b passes |
| 6 | All 14 grep flag requirements have E2E test coverage | VERIFIED | tests/test_grep_flags.py covers GREP-01 through GREP-14 (26 tests) |
| 7 | All 7 blame flag requirements have E2E test coverage | VERIFIED | tests/test_blame_flags.py covers BLAM-01 through BLAM-07 (12 tests) |
| 8 | Tests verify flag translation and warning behavior | VERIFIED | TestGrepTranslation, TestGrepUnsupported, TestBlameTranslation, TestBlameUnsupported classes |
| 9 | Tests follow established test patterns in codebase | VERIFIED | Uses sl_repo_with_commit fixture, run_gitsl helper, pytest marks |

**Score:** 9/9 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `cmd_grep.py` | Grep flag extraction and translation (80+ lines) | VERIFIED | 144 lines, handles 14 requirements, no stubs |
| `cmd_blame.py` | Blame flag extraction and translation (60+ lines) | VERIFIED | 100 lines, handles 7 requirements, no stubs |
| `tests/test_grep_flags.py` | E2E tests for GREP-01 through GREP-14 (150+ lines) | VERIFIED | 179 lines, 26 tests, all pass |
| `tests/test_blame_flags.py` | E2E tests for BLAM-01 through BLAM-07 (80+ lines) | VERIFIED | 102 lines, 12 tests, all pass |

### Key Link Verification

| From | To | Via | Status | Details |
|------|-----|-----|--------|---------|
| cmd_grep.py | sl grep | run_sl call with translated flags | WIRED | Line 144: `return run_sl(sl_args)` where sl_args starts with "grep" |
| cmd_blame.py | sl annotate | run_sl call with translated flags | WIRED | Line 100: `return run_sl(sl_args)` where sl_args starts with "annotate" |
| gitsl.py | cmd_grep.py | import + dispatch | WIRED | Line 26: `import cmd_grep`, Line 109-110: grep dispatch |
| gitsl.py | cmd_blame.py | import + dispatch | WIRED | Line 22: `import cmd_blame`, Line 97-98: blame dispatch |
| tests/test_grep_flags.py | cmd_grep.py | run_gitsl(['grep', ...]) calls | WIRED | 26 test methods call run_gitsl with grep commands |
| tests/test_blame_flags.py | cmd_blame.py | run_gitsl(['blame', ...]) calls | WIRED | 12 test methods call run_gitsl with blame commands |

**All 21 requirements satisfied.**

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| (none) | - | - | - | No anti-patterns found |

No TODO, FIXME, placeholder, or stub patterns detected in any phase artifacts.

### Human Verification Required

None required. All phase goals can be verified programmatically through:
1. Module imports succeed
2. All 38 E2E tests pass
3. Flag translation and warning behavior verified by tests
4. Critical semantic translations (-v to -V, -b to --ignore-space-change) verified

## Summary

Phase 27 goal fully achieved. Users can search code with git grep flags and view file history with git blame flags. All 21 requirements (14 grep + 7 blame) are implemented with:
- Direct pass-through for compatible flags
- Critical translations for semantic mismatches (grep -v to sl -V, blame -b to sl --ignore-space-change)
- Helpful warnings for unsupported flags with alternative suggestions
- Comprehensive E2E test coverage (38 tests, all passing)
