# Phase 21: Rev-Parse Expansion Verification Report

**Phase Goal:** Users can query repository metadata using git rev-parse flags that tools commonly depend on
**Verified:** 2026-01-21T02:30:00Z
**Status:** passed
**Re-verification:** No - initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | git rev-parse --show-toplevel returns repository root path | VERIFIED | Handler `_handle_show_toplevel()` calls `sl root` and prints result. 3 tests pass: `test_show_toplevel_returns_absolute_path`, `test_show_toplevel_from_subdirectory`, `test_show_toplevel_fails_outside_repo` |
| 2 | git rev-parse --git-dir returns .sl or .hg directory path | VERIFIED | Handler `_handle_git_dir()` calls `sl root`, detects .sl/.hg dir. 2 tests pass: `test_git_dir_returns_vcs_directory`, `test_git_dir_fails_outside_repo` |
| 3 | git rev-parse --is-inside-work-tree returns true inside repo, false outside | VERIFIED | Handler `_handle_is_inside_work_tree()` returns "true"/"false" with exit 0. 2 tests pass: `test_is_inside_work_tree_returns_true`, `test_is_inside_work_tree_returns_false_outside` |
| 4 | git rev-parse --abbrev-ref HEAD returns current bookmark name or HEAD if detached | VERIFIED | Handler `_handle_abbrev_ref()` uses `sl log -T {activebookmark}`, falls back to "HEAD". 2 tests pass: `test_abbrev_ref_returns_bookmark_name`, `test_abbrev_ref_returns_head_when_detached` |
| 5 | git rev-parse --verify validates reference exists and returns full hash | VERIFIED | Handler `_handle_verify()` translates HEAD to `.`, uses `sl log -T {node}`. 3 tests pass: `test_verify_valid_ref_returns_hash`, `test_verify_invalid_ref_fails`, `test_verify_bookmark_returns_hash` |
| 6 | git rev-parse --symbolic returns input in symbolic form | VERIFIED | Handler `_handle_symbolic()` echoes input ref. 2 tests pass: `test_symbolic_head_returns_head`, `test_symbolic_ref_returns_ref` |

**Score:** 6/6 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `cmd_rev_parse.py` | Rev-parse command with expanded flag support | VERIFIED | 179 lines, has all 6 handlers: `_handle_show_toplevel`, `_handle_git_dir`, `_handle_is_inside_work_tree`, `_handle_abbrev_ref`, `_handle_verify`, `_handle_symbolic` |
| `tests/test_rev_parse.py` | E2E tests for all rev-parse requirements | VERIFIED | 183 lines, has 6 test classes: `TestRevParseShowToplevel`, `TestRevParseGitDir`, `TestRevParseIsInsideWorkTree`, `TestRevParseAbbrevRef`, `TestRevParseVerify`, `TestRevParseSymbolic` |

**Level 1 (Existence):** Both files exist
**Level 2 (Substantive):** Both files exceed minimum lines (80+, 100+), no stub patterns found
**Level 3 (Wired):** cmd_rev_parse.py is imported by gitsl.py (line 18), dispatched (line 85-86)

### Key Link Verification

| From | To | Via | Status | Details |
|------|-----|-----|--------|---------|
| cmd_rev_parse.py | sl root | subprocess for --show-toplevel | WIRED | Lines 12, 26, 51 call `["sl", "root"]` |
| cmd_rev_parse.py | sl log -T | subprocess for --abbrev-ref and --verify | WIRED | Lines 67 and 93 use `sl log -r ... -T` |
| gitsl.py | cmd_rev_parse | import and dispatch | WIRED | Line 18: `import cmd_rev_parse`, Lines 85-86: `if parsed.command == "rev-parse": return cmd_rev_parse.handle(parsed)` |

### Requirements Coverage

| Requirement | Status | Evidence |
|-------------|--------|----------|
| REVP-01: `--show-toplevel` translates to `sl root` | SATISFIED | `_handle_show_toplevel()` verified |
| REVP-02: `--git-dir` returns `.sl` directory path | SATISFIED | `_handle_git_dir()` verified |
| REVP-03: `--is-inside-work-tree` returns true/false | SATISFIED | `_handle_is_inside_work_tree()` verified |
| REVP-04: `--abbrev-ref HEAD` returns current bookmark name | SATISFIED | `_handle_abbrev_ref()` verified |
| REVP-05: `--verify` validates object reference | SATISFIED | `_handle_verify()` verified |
| REVP-06: `--symbolic` outputs in symbolic form | SATISFIED | `_handle_symbolic()` verified |
| REVP-07: Document `--short HEAD` already implemented | SATISFIED | Existing tests pass (3 tests in TestRevParseShortHead) |

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| None | - | - | - | No anti-patterns detected |

No TODO/FIXME comments, no placeholder patterns, no empty returns found in cmd_rev_parse.py.

### Test Results

**Rev-parse tests:** 19/19 passed
- TestRevParseShortHead: 3 tests
- TestRevParseExitCodes: 2 tests
- TestRevParseShowToplevel: 3 tests
- TestRevParseGitDir: 2 tests
- TestRevParseIsInsideWorkTree: 2 tests
- TestRevParseAbbrevRef: 2 tests
- TestRevParseVerify: 3 tests
- TestRevParseSymbolic: 2 tests

**Full test suite:** 211/211 passed (no regressions)

### Human Verification Required

None - all requirements can be verified programmatically through tests.

### Summary

Phase 21 goal is fully achieved. Users can now query repository metadata using:
- `git rev-parse --show-toplevel` - repository root path
- `git rev-parse --git-dir` - VCS directory (.sl/.hg)
- `git rev-parse --is-inside-work-tree` - true/false
- `git rev-parse --abbrev-ref HEAD` - current bookmark/branch name
- `git rev-parse --verify <ref>` - validate and get full hash
- `git rev-parse --symbolic <ref>` - symbolic output

All 6 new flag handlers are implemented, tested (14 new tests), and wired. The existing `--short HEAD` functionality is preserved (REVP-07). All 211 tests pass with no regressions.
