## Wiring Verification

### Phase 01 (Script Skeleton) Exports

| Export | Used By | Status |
|--------|---------|--------|
| `gitsl.py:main()` | Entry point | CONNECTED (direct execution) |
| `parse_argv` | `gitsl.py` | CONNECTED |
| `ParsedCommand` | All `cmd_*.py` handlers | CONNECTED (7 handlers) |
| `is_debug_mode` | `gitsl.py` | CONNECTED |
| `print_debug_info` | `gitsl.py` | CONNECTED |
| `VERSION` | `gitsl.py` | CONNECTED |

### Phase 02 (Test Infrastructure) Exports

| Export | Used By | Status |
|--------|---------|--------|
| `run_gitsl` | 10 test files | CONNECTED |
| `run_git` | `test_harness.py` | CONNECTED |
| `CommandResult` | `conftest.py`, `test_harness.py` | CONNECTED |
| `run_command` | `conftest.py`, 3 test files | CONNECTED |
| `compare_exact` | `test_harness.py` | CONNECTED |
| `compare_semantic` | `test_harness.py` | CONNECTED |
| `assert_commands_equal` | `test_harness.py` | CONNECTED |
| `git_repo` fixture | 5 test files | CONNECTED |
| `sl_repo` fixture | 6 test files | CONNECTED |
| `sl_repo_with_commit` fixture | 4 test files | CONNECTED |
| `sl_repo_with_commits` fixture | `test_cmd_log.py` | CONNECTED |

### Phase 03 (Execution Pipeline) Exports

| Export | Used By | Status |
|--------|---------|--------|
| `run_sl` | `cmd_status.py`, `cmd_log.py`, `cmd_diff.py`, `cmd_init.py`, `cmd_add.py`, `cmd_commit.py` | CONNECTED (6 handlers) |
| Handler interface `handle(ParsedCommand) -> int` | All `cmd_*.py` | CONNECTED (7 handlers) |

### Command Handler Wiring

| Handler | Dispatched From | Uses `run_sl` | Uses `ParsedCommand` |
|---------|-----------------|---------------|----------------------|
| `cmd_status.py` | `gitsl.py:61` | YES | YES |
| `cmd_log.py` | `gitsl.py:64` | YES | YES |
| `cmd_diff.py` | `gitsl.py:67` | YES | YES |
| `cmd_init.py` | `gitsl.py:70` | YES | YES |
| `cmd_rev_parse.py` | `gitsl.py:73` | NO (capture_output) | YES |
| `cmd_add.py` | `gitsl.py:76` | YES | YES |
| `cmd_commit.py` | `gitsl.py:79` | YES | YES |

**Note:** `cmd_rev_parse.py` intentionally uses `subprocess.run` directly with `capture_output=True` for output transformation, not `run_sl`. This is documented as "capture_output pattern" in Phase 04-02 SUMMARY.

## E2E Flow Verification

### Flow 1: Git Workflow (status --porcelain -> add -> commit -> log --oneline)

| Step | Command | Handler | Output | Status |
|------|---------|---------|--------|--------|
| 1 | `gitsl status --porcelain` | `cmd_status.py` | `" M file.txt\n?? new.txt\n"` | PASS |
| 2 | `gitsl add -A` | `cmd_add.py` | `"adding new.txt\n"` | PASS |
| 3 | `gitsl commit -m "msg"` | `cmd_commit.py` | Commit hash | PASS |
| 4 | `gitsl log --oneline` | `cmd_log.py` | `"<12-char-hash> msg\n"` | PASS |

**Verification:** Tested manually in sl init'd repo. All steps complete, status clean after commit.

### Flow 2: Debug Mode for All Commands

| Command | Debug Output | Status |
|---------|--------------|--------|
| `GITSL_DEBUG=1 gitsl status --porcelain` | `[DEBUG] Would execute: sl status --porcelain` | PASS |
| `GITSL_DEBUG=1 gitsl log --oneline -5` | `[DEBUG] Would execute: sl log --oneline -5` | PASS |
| `GITSL_DEBUG=1 gitsl add -A` | `[DEBUG] Would execute: sl add -A` | PASS |
| `GITSL_DEBUG=1 gitsl commit -m "test"` | `[DEBUG] Would execute: sl commit -m test` | PASS |
| `GITSL_DEBUG=1 gitsl push origin main` | `[DEBUG] Would execute: sl push origin main` | PASS |

**Note:** Debug mode intercepts before handler dispatch, so unsupported commands also show debug output.

### Flow 3: Unsupported Commands (Graceful Fallback)

| Command | stdout | stderr | Exit Code | Status |
|---------|--------|--------|-----------|--------|
| `gitsl push origin main` | (empty) | `gitsl: unsupported command: git push origin main` | 0 | PASS |
| `gitsl rebase main` | (empty) | `gitsl: unsupported command: git rebase main` | 0 | PASS |
| `gitsl fetch --all` | (empty) | `gitsl: unsupported command: git fetch --all` | 0 | PASS |
| `gitsl checkout -b feature` | (empty) | `gitsl: unsupported command: git checkout -b feature` | 0 | PASS |

**Verification:** Exit code 0 ensures calling tools don't break.

### Flow 4: Entry Point Special Cases

| Input | Expected Output | Exit Code | Status |
|-------|-----------------|-----------|--------|
| `gitsl --version` | `gitsl version 0.1.0` | 0 | PASS |
| `gitsl --help` | Usage text | 0 | PASS |
| `gitsl` (no args) | `usage: git <command> [<args>]` to stderr | 1 | PASS |

**Total:** 91 tests across 11 test files

## Orphaned Code Analysis

### Orphaned Exports: NONE

All exports from all phases are used by at least one consumer.

### Orphaned Test Utilities: NONE

All test fixtures and helpers are used in tests.

### Dead Code: NONE

No unused functions, classes, or imports detected.

---

## Missing Connections: NONE

All expected phase-to-phase connections are present:
- Entry point dispatches to all handlers
- All handlers use common.py utilities
- All tests use test infrastructure
- All flag translations are tested

---

## Broken Flows: NONE

All 4 E2E flows complete without breaks:
1. Git workflow completes successfully
2. Debug mode works for all command types
3. Unsupported commands exit gracefully
4. Entry point handles special cases correctly

---

## Unprotected Routes: N/A

This is a CLI tool, not a web application. No auth protection required.

---
