Commit Range Audit (base..head) The branch contains 9 atomic commits implementing requirements F1–F6 plus review follow-up R1: 1. `75936f1`: `test(followups): F1 - A8 writes the marker lstart as loop_lock.sh reads it` 2. `5edf913`: `fix(followups): F2 - Python entry points report an unreadable env file in one line` 3. `71ea809`: `fix(followups): F3 - .mam.env BOM, repeated keys and a missing MAM_ENV_FILE` 4. `8b04639`: `fix(followups): F4a/F4c - the runner's wait knobs follow the integer rule; MAM_WAIT_GRACE_S documented` 5. `fb1b93c`: `fix(followups): F4b - bash integer knobs that reach [ -ge/-le/-gt ] or sleep go through mam_int_knob` 6. `c252ac4`: `fix(followups): F5 - no test switch in the stall watcher` 7. `1e92ddc`: `test(followups): F6 - the wrapper vanishes inside the second wait; the <= 60 s is the herdr wait's` 8. `95eabc6`: `fix(followups): F2 - job_subscriber returns the env-file failure by name` 9. `75f364e`: `fix(followups): F2 review R1 - a failed env load is not cached as loaded` --- ## 3. Requirement Verification & Findings ### F1: Date-dependent Test Bug Resolution - **Issue**: `tests/test_issue21_acceptance.py::test_a8_second_loop_is_refused_before_a_scheduler_exists` failed on calendar days 1–9 due to `ps -o lstart=` double-space padding vs `mam_lstart` single-space normalization (`tr -s ' '`). - **Implementation**: - `_marker_lstart` normalizes ps output with `" ".join(out.split())` in [`tests/test_issue21_acceptance.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/tests/test_issue21_acceptance.py#L554-L559). - Parameterized with `_PADDED_PS` shim to deterministically test single-digit day padding across all runs. - **Verification**: `test_issue21_acceptance.py` passes completely (10/10 passed). ### F2: Python Entry Point EnvFileError Reporting & Retry Behavior (including R1) - **Issue**: Missing/unreadable `.mam.env` should produce a single error line (`ERROR: : cannot read ()`) and exit with returncode 1, without a Python traceback or leaking secrets. Furthermore, a failed load must not be cached as loaded so subsequent entry point invocations in the same process can retry or fail consistently. - **Implementation**: - [`load_env_or_report()`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/lib_py/delegation/mqtt_common.py#L130-L141) wraps `ensure_env_loaded()` and prints `ERROR: ` to `sys.stderr` returning `False`. - In [`mqtt_common.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/lib_py/delegation/mqtt_common.py#L125), `_env_loaded = True` is only assigned after `_load_dotenv()` successfully completes. - All process entry points (`publish_event`, `registry`, `job_subscriber`, `cli`, `bench`, `heartbeat`, `remote`) guard their main functions with `if not mqtt_common.load_env_or_report(): return 1`. - Added [`test_a1_a_failed_load_is_not_cached_as_loaded`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/tests/test_issue26_envfile.py#L721-L740) validating that consecutive invocations with broken files fail with rc 1 and do not register jobs, and once repaired, reload and succeed. - Updated documentation in [`MESSAGING.md`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/MESSAGING.md#L509-L511). - **Verification**: `tests/test_issue26_envfile.py` passes all 38 tests. ### F3: `.mam.env` Refinements - **Implementation**: - `parse()` in [`lib_py/delegation/envfile.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/lib_py/delegation/envfile.py#L58) uses `utf-8-sig` encoding, properly ignoring leading BOMs. - Repeated keys retain their first defined value, documented in [`.mam.env.example`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.mam.env.example#L497). - Missing `MAM_ENV_FILE` is skipped silently without falling back to ambient search. - **Verification**: Regression tests `test_a7_a_leading_bom_is_not_part_of_the_first_key`, `test_a7_a_repeated_key_keeps_its_first_value_as_documented`, and `test_a7_a_missing_explicit_file_loads_nothing_and_says_nothing` all pass. ### F4: Integer Knob Expansion & `lib_int.sh` - **Implementation**: - Created standalone [`.agents/skills/lib_int.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/lib_int.sh) containing `mam_int` and `mam_int_knob`. Added to [`deploy/remove.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/deploy/remove.sh#L85). - Sourced by scripts executed with and without `lib.sh` ([`loop_lock.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/multi-agent-mux-loop/scripts/loop_lock.sh), [`diff_collect.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/multi-agent-mux-loop/scripts/diff_collect.sh), [`lib.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/lib.sh), [`reconcile.sh`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/multi-agent-mux-monitor/scripts/reconcile.sh)). - Python loop runner [`LoopRunner._int_knob`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/lib_py/loop/runner.py#L355) parses `MAM_WAIT_GRACE_S`, `MAM_CHILD_WAIT_S`, and `MAM_JOB_TREE_MAX`, falling back cleanly to defaults upon invalid input. - Documented in [`multi-agent-mux-loop/SKILL.md`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/multi-agent-mux-loop/SKILL.md#L427). - Fractional float nature of `SKS_QUIESCENT_INTERVAL` is preserved and documented in `NOT_ARITHMETIC`. - **Verification**: `tests/test_issue26_ints.py` passes all 93 test cases. ### F5: Removal of Test Hooks in Production Code - **Implementation**: - Removed `MAM_TEST_UNRELIABLE_AGENT` from [`lib_py/stall_watch.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/lib_py/stall_watch.py). - [`tests/test_issue30_stall_watch.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/tests/test_issue30_stall_watch.py#L924-L938) sets `adapter.agent_status_reliable = property(lambda self: False)` via test-side injection. - **Verification**: `test_s13_the_unreliable_case_needs_no_switch_in_the_product` and all 48 stall watch tests pass. ### F6: Documentation Precision & Mid-Wait Termination Testing - **Implementation**: - Refined `<= 60 s` comment in [`multi-agent-mux-delegate-job/SKILL.md`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/.agents/skills/multi-agent-mux-delegate-job/SKILL.md#L412) to specifically denote herdr wait duration. - Added `in_wait` hook in [`tests/test_issue30_stall_watch_stop.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2/tests/test_issue30_stall_watch_stop.py#L979-L1018) ensuring deterministic termination during the second wait tick. - **Verification**: All 11 tests in `test_issue30_stall_watch_stop.py` pass cleanly. --- ## 4. Test Suite Execution Results All required test suites were executed inside the verification path (`/var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261001T230324Z-b511bf/2`) using Python venv with `--basetemp=/tmp/pytest-followups-clean`: | Test Suite | Result | Time | |---|---|---| | `tests/test_issue26_envfile.py` | 38 passed | 8.26 s | | `tests/test_issue26_ints.py` | 93 passed | 38.29 s | | `tests/test_issue30_stall_watch_stop.py` + `tests/test_version_consistency.py` | 14 passed | 31.16 s | | `tests/test_tier1_unit.py` | 67 passed | 59.75 s | | `tests/test_issue21_acceptance.py` | 10 passed | 39.56 s | | `tests/test_issue30_stall_watch.py` | 48 passed, 1 skipped | 263.44 s | **Total Tests**: 270 passed, 1 skipped, 0 failed. --- ## 5.
