+# Cross-review: Issue #3 implementation (daemon detach + Class A resume)
+
+- **Reviewer**: `reviewer-creator-grok-01`
+- **Job**: `dccd6220`
+- **Diff**: `lib.sh` shim bootstrap, `resume_session.sh`, `update_yaml_resumed.sh`, tests (`test_uuid_target.py`, `test_herdr_shim_contract.py`)
+- **Method**: live code + `pytest` of t8/t14/t15/t16/h26 and full `test_uuid_target.py`. `verify_session.py` has **no** git diff.
+
+---
+
+## 1. Daemon spawn (`lib.sh` / `.mam/shim/herdr`)
+
+Replaces `nohup … & disown` with:
+
+```bash
+_mam_server_pid=$(python3 -c '
+import subprocess, sys
+p = subprocess.Popen(sys.argv[1:], start_new_session=True, ...)
+print(p.pid)
+' "$REAL_HERDR" --session "$_MAM_SESSION" server)
+```
+
+- `python3 -c` → `sys.argv[0]=='-c'`, `sys.argv[1:]` is the herdr argv. Correct.
+- Single-quoted `-c` body, so `$_MAM_SESSION` is expanded by bash as an argument, not inside Python. Correct.
+- Child is session-leader via `os.setsid`; short-lived Python parent exits; herdr is reparented. PGID no longer follows the shim.
+- `test_h26` extracts the **shipped** statement and asserts child PGID ≠ shell PGID.
+
+**Met.** Portable (no macOS `setsid` binary).
+
+## 2. Class A 0-turn resume
+
+Empty UUID: `agy|hermes|opencode` → `FRESH_SPAWN=1` + `spawn-spec` (not `resume-spec`). `claude|grok` still `exit 1`. YAML update allows empty `--uuid`, stamps `herdr_session_epoch` / `pending-discovery` / `session_id_verified: false` so reconcile cannot pin a pre-resume transcript.
+
+Tests: t14 (agy dry-run, no `--conversation`), t15 (claude never-created still RC=1), t16 (live resume bumps epoch).
+
+**Met.** `--role` handoff is no longer required for Class A 0-turn recovery.
+
+## 3. Class B hatch — preserved
+
+`verify_session.py:99-101` unchanged (`git diff` empty). `test_t8_resume_unmaterialized_assigned_id` **passed** in this run.
+
+## Tests (this reviewer)
+
+```
+pytest tests/test_uuid_target.py \
+       tests/test_uuid_target.py::test_t8_… \
+       tests/test_uuid_target.py::test_t14_… \
+       tests/test_uuid_target.py::test_t15_… \
+       tests/test_uuid_target.py::test_t16_… \
+       tests/test_herdr_shim_contract.py::test_h26_…
+→ 20 passed in 246.19s
+```
+
+`bash -n` on `lib.sh`, `resume_session.sh`, `update_yaml_resumed.sh` clean.
+
+## Residual nits (do not block)
+
+- Already-running Class A + empty UUID still calls `update_yaml_resumed.sh --uuid ""`, which **re-stamps epoch** without respawning. Rare (resume-when-alive). Prefer skipping the epoch reset on the has-session attach path.
+- No `MAM_VERSION` bump (still `4.1.2`). Fine if this lands in the same unreleased PATCH; bump to 4.1.3 if 4.1.2 already shipped.
+- Resume `SKILL.md` still says empty UUID → create. Docs drift only.
+
+No `[ESCALATE: PLANNER]`.
+
+---
+
+[VERDICT: PASS]
