## 3. Evaluation of Review Items

### Item 1: Accuracy of Code Block Classification
- **Removed (a) Blocks (5 blocks)**:
  1. `multi-agent-mux-resume` Workflow (base lines 59–118): Replaced by `resume_session.sh` entry point call. All original steps are accounted for in [`resume_session.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261003T222707Z-a0de27/1/.agents/skills/multi-agent-mux-resume/scripts/resume_session.sh):
     - Session ID resolution: lines 111–130 (`resolve_session_id.sh`).
     - Fresh-spawn fallback for Class A agents: lines 133–144.
     - herdr alive check: lines 147–158 (updates YAML row and exits 0; attach is intentionally separate).
     - Command construction (`CMD_FULL`): lines 172–197 (via adapter `resume-spec`/`spawn-spec`).
     - Spawning session: line 237 (`herdr new-session`).
     - Dialog handling: line 241 (`handle_startup_dialogs`).
     - YAML update: lines 247–250 (`update_yaml_resumed.sh`).
  2. `multi-agent-mux-stop` Pre-flight (base lines 38–63): Checked directly inside [`stop_session.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261003T222707Z-a0de27/1/.agents/skills/multi-agent-mux-stop/scripts/stop_session.sh) at lines 99, 140–143, and 184–188.
  3. `multi-agent-mux-create` Pre-flight (base lines 35–52): Checked directly inside [`create_session.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261003T222707Z-a0de27/1/.agents/skills/multi-agent-mux-create/scripts/create_session.sh) at lines 111–156 (herdr installation, agent binary, auth, workspace).
  4. `multi-agent-mux-create` Workflow (base lines 168–220): Checked and handled entirely by [`create_session.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261003T222707Z-a0de27/1/.agents/skills/multi-agent-mux-create/scripts/create_session.sh) (adapter `spawn-spec`, TUI readiness wait, exit code handling).
  5. `multi-agent-mux-create` Manual YAML row append (base lines 226–252): Handled automatically by [`create_session.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261003T222707Z-a0de27/1/.agents/skills/multi-agent-mux-create/scripts/create_session.sh) at lines 491–610.
- **Retained (b) Blocks (5 blocks)**:
  - `create` post-create checks, `monitor` agent-run polling loop, `resume` post-resume checks, `status` pre-flight checks, and `stop` post-stop checks. None of these have a standalone script entry point; they remain documented as manual/verification steps and provide input for Stage 3.
- **Conclusion**: Classification across all 37 blocks is verified with valid `file:line` evidence.

### Item 2: Option Tables, Exit Codes, and Documentation Corrections
- **Exit Code Tables**:
  - `create_session.sh`: Codes 0, 1, 2, 3, 4, 42, 43, `other`. Passthrough `4` from Python `SystemExit(4)` on duplicate running row (`create_session.sh:515`) is explicitly verified.
  - `resume_session.sh`: Codes 0, 1, 2, `other`.
  - `stop_session.sh`: Codes 0, 1, 2, 3, 4, `other`. Follow-up R1 (`e6a46cd`) and R2 (`8d26106`) verified that passthrough code `1` from post-stop registry update (`stop_session.sh:310`) is properly declared in `entry_points.passthrough` and explained in the table.
- **Documentation Discrepancy Corrections**:
  1. `resume` Case 3: Accurately documents that an already-running session updates the row and exits 0 without auto-attaching or checking permissions (`SKILL.md:240`).
  2. `stop` `--purge-conversation`: Clarified that `--yes` is required to avoid exit 3 (`SKILL.md:461`).
  3. `status` `--json`: Aligned schema with `reconcile.sh` drift object and `sessions_detail` list (`SKILL.md:364-414`).
  4. `create` `cmd_full`: Replaced static table with note that command line is determined by adapter `spawn-spec` (`SKILL.md:218`).
  5. `create` nonexistent `agent-sessions-yaml-edit`: Reference removed (`SKILL.md:218`).

### Item 3: Agent Executability & Safety
- Each skill workflow now directs the agent to a clear, robust one-line CLI invocation.
- Destructive workflows (e.g., `--purge-conversation`) explicitly mandate interactive user confirmation before passing `--yes`.
- Error recovery guidance (e.g., inspecting status if post-kill or post-spawn updates fail) is thoroughly documented.

### Item 4: Robustness of Test Guard (`test_issue42_skill_blocks.py`)
- Code block parsing accurately accounts for variable fence lengths, indentation inside lists, and language tags.
- Exit code analysis (`_scan_exits`) skips comments and heredoc blocks to separate shell `exit N` from Python `SystemExit(N)`.
- Test suite validates that all 8 skills have inventories, all removed blocks have valid script replacements, all declared exit codes and passthroughs match script reality, and all evidence pointers reference valid file lines.
- Existing documentation tests in [`tests/test_tier2_component.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261003T222707Z-a0de27/1/tests/test_tier2_component.py) continue to pass completely (42/42 passed).

### Item 5: Scope & Boundaries
- `git diff --stat` confirms only documentation (`SKILL.md`), test data (`tests/data/skill_code_blocks.json`), and test code (`tests/test_issue42_skill_blocks.py`) were changed.
- No product logic changed.
- No version bump.

### Item 6: Inquiry on `tests/test_issue10_13_purge.py` Baseline
- Executed `tests/test_issue10_13_purge.py` in the verification environment: 23 passed in 11.10 s.
- Confirmed that the 12 failures cited in PR description refer to existing Linux-specific CI baselines (Issue #28). On this macOS host, all tests pass cleanly and are unrelated to PR #46.

## 4. Test Suite Execution Results

All tests executed in the verification worktree (`/var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261003T222707Z-a0de27/1`) with `--basetemp=/tmp/pytest-pr46-review`:

| Test File | Result | Duration |
|---|---|---|
| `tests/test_issue42_skill_blocks.py` | 28 passed, 1 skipped* | 0.07 s |
| `tests/test_tier2_component.py` | 42 passed | 249.66 s |
| `tests/test_orc_onboard.py` | 13 passed | 2.59 s |
| `tests/test_loop_cli.py` | 20 passed | 37.19 s |
| `tests/test_o1_rebuttal.py` | 11 passed | 1.83 s |
| `tests/test_version_consistency.py` | 15 passed | 2.69 s |
| `tests/test_issue10_13_purge.py` | 23 passed | 11.10 s |

*\* Note: `test_claude_skills_link_resolves_to_agents_skills` skipped as expected because `.claude/skills` symlink is untracked and absent in the detached review worktree.*

**Total Tested**: 152 passed, 1 skipped, 0 failed.

## 5. Conclusion

All requirements for Issue #42 Stages 1 and 2 are cleanly and accurately satisfied without product regressions or scope creep.

[VERDICT: PASS]
