## 1. Executive Summary
|
||
|
||
PR #73 resolves Issue #71 across all 10 scope items and review refinements (`A`–`F`):
|
||
1. Unifies `attach_command` construction in [`lib_py/agents/sanitize.py::attach_command`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib_py/agents/sanitize.py#L34-L42) (`herdr --session <server> agent attach <sanitized_name>`) across `create_session.sh`, `update_yaml_resumed.sh` (both branches), and `reconcile.sh`, and teaches the `lib.sh` shim's `herdr agent attach` branch to resolve its target via `_resolve_herdr_target`.
|
||
2. Removes `kill_command` and `start_command` from newly written rows, `status.sh --json`, and `SKILL.md` examples, and replaces direct `herdr kill-session` cleanup hints in `create_session.sh` (exit 43) and `id_order.py` with `stop_session.sh --session <name> --herdr-session <srv>`.
|
||
3. Adds row-less session closing (`stop_rowless`) to [`stop_session.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-stop/scripts/stop_session.sh#L123-L165) with strict registry readability gating (`load_state_json strict`), workspace boundary enforcement (`os.path.realpath` prefix-safe check, exit 5 on foreign workspace), server selection parity with `create_session.sh`, and registry immutability.
|
||
4. Consolidates `_sanitize_herdr_agent_name` into a single definition in [`lib.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib.sh#L40-L85) injected into the generated shim via `declare -f`, achieving exact parity with Python's `sanitize_herdr_agent_name` across ASCII, non-ASCII/multibyte, option-like (`-n`, `-e`), and newline-containing names, while failing closed (nonzero, stderr) when no hash tool or `python3` is available instead of emitting `00000000` or truncated names.
|
||
5. Introduces registry format version 2 (`registry_format: 2`) in [`lib_py/registry_format.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib_py/registry_format.py#L1-L92) and [`lib_py/atomic_yaml.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib_py/atomic_yaml.py#L121-L138), migrating under the writer lock (`BEGIN IMMEDIATE`) and repairing stale YAML copies on retry.
|
||
6. Computes `herdr_name` once in `StallWatch.__init__` and passes it as a required keyword-only argument `name` to `HerdrSource`.
|
||
|
||
All 10 review checklist items, macOS `/bin/bash 3.2.57` and `/usr/bin/python3 3.9.6` compatibility checks, negative regression on `base` (`68 failed, 2 passed`), and 461 functional/integration tests on `head` (`461 passed, 1 skipped, 0 failed`) pass on macOS Darwin arm64.
|

|
||
|
||
## 2. Checklist Verification (Items 1–10)
|
||
|
||
### 1. Completion Criteria & Scope Discipline (Issue #71 & Scope Comment Items 1–10)
|
||
- **Verified (`PASS`)**:
|
||
- Every requirement in Issue #71 and the "범위 정리" comment (items 1–10) is implemented and covered by regression tests.
|
||
- Out-of-scope Issue #72 (`multi-agent-mux-update` skill) is not pulled into this PR; only the `python3 -m lib_py.registry_format --yaml <path>` entry point specified in item 9 is provided for #72 to call. `MAM_VERSION` (`4.10.1`) and `VERSIONS.md` are untouched as intended.
|
||
|
||
### 2. Regression Suite `tests/test_issue71_herdr_names.py` (Base vs Head & Reconcile Pane Precondition)
|
||
- **Verified (`PASS`)**:
|
||
- **Base (`29cc4fd90478936f15387a7665e2c95d13a3f14c`)**: Checked out into an isolated temporary directory outside the review worktree and ran `tests/test_issue71_herdr_names.py` (70 tests): **68 failed, 2 passed in 104.17s** (the only 2 passing tests on `base` are `test_the_names_need_converting_and_the_plain_one_does_not` and `test_wrapper_attach_calls_herdr_with_the_herdr_name[lab-plain-creator-claude]`, matching the PR description).
|
||
- **Head (`5f6065344f800c2c5ad6f802e95e9e8ff5cc7b26`)**: All **70 passed** (including all 4 `hashers` parameterizations: `shasum`, `sha1sum`, `openssl`, `python3`).
|
||
- **Reconcile test precondition**: [`test_reconcile_registers_with_the_attach_command`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/tests/test_issue71_herdr_names.py#L128-L141) seeds `mock_herdr` with `agents={name: {"agent": "claude", "status": "running", "cwd": str(mam_sandbox), "workspace_id": "w1", "pid": 9999, "pane_id": "w1:p71", "command": "claude", "buffer": "Ready"}}` and asserts `len(rows) == 1` and `rows[0]["last_visible_note"] == "auto-registered by monitor"` before checking `_assert_new_form(rows[0], rows[0]["herdr_session"])`.
|
||
|
||
### 3. `attach_command` (`lib_py/agents/sanitize.py`) & `lib.sh` Wrapper `agent attach`
|
||
- **Verified (`PASS`)**:
|
||
- [`lib_py/agents/sanitize.py:34-42`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib_py/agents/sanitize.py#L34-L42) defines:
|
||
```python
|
||
def attach_command(server, name):
|
||
return "herdr --session %s agent attach %s" % (
|
||
shlex.quote(server or "default"), shlex.quote(sanitize_herdr_agent_name(name)))
|
||
```
|
||
- Always writes `--session default` when `server` is `"default"` or empty/falsy, and applies `shlex.quote` to both the server and sanitized agent name.
|
||
- Used by all three writers:
|
||
- `create`: [`create_session.sh:512, 566`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-create/scripts/create_session.sh#L512-L566)
|
||
- `resume` (new row and existing row): [`update_yaml_resumed.sh:119, 150, 160`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-resume/scripts/update_yaml_resumed.sh#L119-L160)
|
||
- `reconcile`: [`reconcile.sh:569, 676`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-monitor/scripts/reconcile.sh#L569-L676)
|
||
- In [`lib.sh:605-613`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib.sh#L605-L613), the shim's `agent attach` branch shifts `<target>` (`t="$1"; shift`), resolves `tgt=$(_resolve_herdr_target "$t" || true)`, fails with exit 1 if empty, and invokes `_real_herdr agent attach "$tgt" "$@"`, preserving trailing flags such as `--takeover`.
|
||
|
||
### 4. Removal of `kill_command` & `start_command` and Updated Cleanup Hints
|
||
- **Verified (`PASS`)**:
|
||
- `git grep -E 'kill_command|start_command'` across the repository confirms no production code, skill doc, or active schema assertion reads or writes `kill_command` or `start_command` (the only remaining mentions are in `registry_format.py` to drop them during v1 -> v2 migration and in `test_issue71_herdr_names.py` / `test_tier2_component.py` asserting their absence).
|
||
- [`status.sh:221-231`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-status/scripts/status.sh#L221-L231) and [`multi-agent-mux-status/SKILL.md:94-101`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-status/SKILL.md#L94-L101) no longer include `start_command`, and nothing in the codebase reads `start_command` from `status.sh --json`.
|
||
- The shim's `new-session` and `kill-session` translation branches in `lib.sh` are properly retained because `create_session.sh`, `resume_session.sh`, `stop_session.sh`, and `reconcile.sh` call them internally.
|
||
- Both user-facing cleanup hints now point to `stop_session.sh`:
|
||
- [`create_session.sh:364`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-create/scripts/create_session.sh#L364): `bash .agents/skills/multi-agent-mux-stop/scripts/stop_session.sh --session $SESSION_NAME --herdr-session ${HERDR_SESSION_NAME:-default}`
|
||
- [`lib_py/agents/id_order.py:359-360`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib_py/agents/id_order.py#L359-L360): `bash .agents/skills/multi-agent-mux-stop/scripts/stop_session.sh --session {m['session']} --herdr-session {srv}`
|
||
|
||
### 5. Row-less `stop` (`stop_session.sh`) & Strict Registry Read (`load_state_json strict`)
|
||
- **Verified (`PASS`)**:
|
||
- **Strict registry read gate**: [`stop_session.sh:170-193`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-stop/scripts/stop_session.sh#L170-L193) calls `STATE_JSON=$(load_state_json strict)` first. In [`lib.sh:1597-1631`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib.sh#L1597-L1631), `load_state_json strict` re-raises `sqlite3.OperationalError` on missing `state` or `sessions` tables as well as corrupt DB / malformed YAML, printing to `stderr` and exiting `1`. Furthermore, `MAPPED_DATA` exits `7` **only** when `d.get('herdr_sessions', [])` was validly iterated and had no matching dict row; non-dict rows (`herdr_sessions: [- 42]`) exit `1` (`cannot read the row`).
|
||
- **Workspace boundary check**: [`stop_rowless` (`stop_session.sh:145-155`)](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-stop/scripts/stop_session.sh#L145-L155) resolves both `PANE_CWD` and `WORKSPACE_ROOT` via `os.path.realpath` and checks `cwd == root or cwd.startswith(root + os.sep)`. Verified on macOS that this prevents prefix confusion (`/tmp/ws` vs `/tmp/ws-other`), handles symlinks (`/var` -> `/private/var`), and normalizes trailing slashes; out-of-workspace sessions are refused with exit code `5` before any `kill-session`.
|
||
- **Server selection order**: Matches `create_session.sh:184-188`: `--herdr-session` (`HERDR_SERVER_OPT`) -> ambient `HERDR_SESSION_NAME` (when non-empty and `!= "default"`) -> workspace server via `resolve_herdr_session`.
|
||
- **`--purge-conversation` and exit codes**: Refuses `--purge-conversation` on a row-less session with exit `1`, exits `6` if `herdr has-session` still succeeds after `kill-session`, never mutates `agent-sessions.yaml` or `agent-sessions.db`, and matches [`multi-agent-mux-stop/SKILL.md:59-67`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-stop/SKILL.md#L59-L67).
|
||
|
||
### 6. Single Sanitize Rule in `lib.sh` & macOS BSD / Locale Parity
|
||
- **Verified (`PASS`)**:
|
||
- [`lib.sh:40-85`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib.sh#L40-L85) has the single definition of `_sanitize_herdr_agent_name`. [`_init_herdr_isolation` (`lib.sh:179-182`)](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib.sh#L179-L182) writes `declare -f _sanitize_herdr_agent_name` into the generated shim (`$wrapper_dir/herdr`).
|
||
- Removed the duplicate definition in the shim heredoc, removed `"00000000"` and `${s:0:32}` fallbacks, and removed `has-session`'s relative-path `sys.path.insert(0, os.path.abspath(".agents/skills"))` + `lambda s: s.lower()[:32]` fallback (`lib.sh:633-647` now computes `ssess=$(_sanitize_herdr_agent_name "$sess") || exit 1` in bash and passes `TARGET_SAN="$ssess"`).
|
||
- **macOS `/bin/bash 3.2.57`, BSD `tr`/`sed`, and locale (`LC_ALL=C` and `LC_ALL=en_US.UTF-8`) verification**:
|
||
- Pure-ASCII check uses `LC_ALL=C tr -d '\000-\177'`. For ASCII inputs, `printf '%s' "$n" | tr '\n' '-' | tr '[:upper:]' '[:lower:]' | sed -E 's/[^a-z0-9_-]/-/g'` avoids `echo` flag parsing (`-n`, `-e`, `-En`) and converts `\n` to `-` before `sed` or command substitution `$(...)` can strip trailing newlines.
|
||
- For non-ASCII inputs (`İ`, `é`, `ü`, `K`, CJK/Hangul, emoji), it delegates lowercasing and `re.sub(r"[^a-z0-9_-]", "-", ...)` to `python3` so character-by-character replacement and Unicode case folding (`\u0130`.lower() -> `'i\u0307'` -> `'i-'`) match `lib_py.agents.sanitize.sanitize_herdr_agent_name` byte-for-byte, and fails closed (exit 1, stderr) if `python3` is unavailable.
|
||
|
||
### 7. Registry Format Version 2 (`lib_py/registry_format.py`, `lib_py/atomic_yaml.py`)
|
||
- **Verified (`PASS`)**:
|
||
- Inside [`atomic_dump_yaml_main` (`lib_py/atomic_yaml.py:121-138`)](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib_py/atomic_yaml.py#L121-L138), after acquiring the flock and `BEGIN IMMEDIATE` and loading `state` + `sessions`, if `from_version < registry_format.CURRENT` (`2`), `registry_format.migrate(d)` runs before the caller's mutation and sets `force_yaml = True`.
|
||
- Migrates all rows in `herdr_sessions` (`running`, `stopped`, `terminated`, `archived`), drops `kill_command` and `start_command`, recomputes `attach_command`, and sets `d["registry_format"] = 2`.
|
||
- If the DB was already at format 2 (`elif row:`) but an earlier YAML `os.replace` failed after `conn.commit()`, `force_yaml = registry_format.stored_version(y) < registry_format.CURRENT` detects the stale YAML and rewrites it on the next write.
|
||
- **Future format preservation**: Verified that when `registry_format` > 2 (e.g., `3`), `stored_version(d)` returns `3`, `from_version < CURRENT` is `False`, and `force_yaml` is `False` — the writer neither downgrades `registry_format` nor clobbers future fields.
|
||
- **Other registry paths**: Checked all references to `agent-sessions.yaml` across `.agents/skills/`; `atomic_dump_yaml` is the sole writer in production (`create_session.sh`, `update_yaml_resumed.sh`, `stop_session.sh`, `reconcile.sh`, `orc_onboard.sh`), while `load_state_json` (`lib.sh` / `lib_py/state.py`) is strictly read-only.
|
||
- **CLI entry point**: `PYTHONPATH=.agents/skills python3 -m lib_py.registry_format --yaml <path>` prints `registry-format: <from> -> <to>, rows changed: <n>` and exits `0` (or nonzero with `registry-format: error: ...` on stderr when missing/failing), matching its module docstring contract.
|
||
|
||
### 8. `stall_watch.py` Single Sanitization Point
|
||
- **Verified (`PASS`)**:
|
||
- In [`.agents/skills/lib_py/stall_watch.py:158-163, 229-230`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/lib_py/stall_watch.py#L158-L230), `StallWatch.__init__` computes `self.herdr_name = sanitize_herdr_agent_name(args.target)` once and passes `name=self.herdr_name` (required keyword-only parameter) to `HerdrSource`.
|
||
- `tests/test_issue66_stall_watch_sanitized_name.py` is unmodified in `git diff` and all 7 of its tests pass.
|
||
|
||
### 9. Test Updates, `skill_code_blocks.json`, and `test_s11` Anchor (`0fc162e`)
|
||
- **Verified (`PASS`)**:
|
||
- `tests/test_issue50_pane_lock.py`, `tests/test_issue21_worktree_prereqs.py`, `tests/test_tier1_unit.py`, `tests/test_tier2_component.py`, and `tests/test_tier3_integration.py` preserve their original test intent after replacing assertions on removed `start_command`/`kill_command` fields.
|
||
- `tests/data/skill_code_blocks.json` and `tests/test_issue42_skill_blocks.py` pass all 96 skill-block verification tests.
|
||
- In [`tests/test_issue23_24_startup_path.py:306-335`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/tests/test_issue23_24_startup_path.py#L306-L335), `test_s11_this_branch_does_not_change_the_generated_shim` pins `base = os.environ.get("MAM_BASE_SHA", "0fc162e")` and extracts both `_sanitize_herdr_agent_name() { ... }` and the `cat <<'EOF'` heredoc body in `_heredoc_body`. Commit `0fc162e` is an ancestor of `HEAD` (`5f60653`) on `fix/issue-71`; when merged into `main` via merge commit (as documented in PR #73), `0fc162e` remains reachable in git history so `test_s11` actively verifies the shim rather than skipping. (The `if show.returncode != 0: pytest.skip(...)` guard is pre-existing for shallow/archive checkouts without history.)
|
||
|
||
### 10. macOS Compatibility (`/usr/bin/python3 3.9.6`, `/bin/bash 3.2.57`, BSD Userland, SQLite WAL)
|
||
- **Verified (`PASS`)**:
|
||
- Parsed all 16 modified/added Python files with `/usr/bin/python3` (`3.9.6`) `ast.parse(..., feature_version=(3, 9))` and imported `lib_py.agents.sanitize`, `lib_py.registry_format`, `lib_py.atomic_yaml`, and `lib_py.stall_watch` under system Python 3.9.6.
|
||
- Checked all 7 modified bash scripts and the generated `.mam/shim/herdr` with `/bin/bash -n` (`GNU bash 3.2.57(1)-release`); no bash 4+ constructs (`declare -A`, `${var,,}`, `mapfile`, `readarray`) are used.
|
||
- In `tests/test_issue71_herdr_names.py:514-527`, `test_stop_does_not_take_an_unreadable_registry_for_no_row` unlinks `agent-sessions.db*` / `agent-sessions.db-*` before writing corrupt DB/YAML fixtures, properly accounting for macOS SQLite's persistent `-wal`/`-shm` sidecars.

## 4. Defects & Observations
|
||
|
||
### Blocking Defects
|
||
- None.
|
||
|
||
### Non-Blocking Observations
|
||
- In [`.agents/skills/multi-agent-mux-delegate-job/multi-agent-mux-delegate-job:1021`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261026T133440Z-c8961b/2/.agents/skills/multi-agent-mux-delegate-job/multi-agent-mux-delegate-job#L1021), the informational message after `send-keys` prints `(연결하려면: HERDR_SESSION_NAME=$HERDR_SESSION_NAME herdr agent attach $sess — lib.sh를 source한 셸에서 실행)`. Because PR #73 updated the `lib.sh` shim's `herdr agent attach` handler to resolve `$sess` via `_resolve_herdr_target`, this command works as stated when `lib.sh` is sourced, though a future cleanup could also print the native `herdr --session ... agent attach ...` form.
