Small code-review leftover: efArrSc() keeps only the last '83' key reference
of a malformed multi-reference AT control reference template (compliant CRTs
carry exactly one, ISO 7816-4 6.3.1) - now said so in the code.
The scp81-findings log needs no new rows: no new live SCP81 tests were run
(it is current through 2026-09-16h; the "load/store over SCP81" item in its
Next-tests list is already verified).
Comment-only index.html change -> sw cache simple-v257 (version stays 3.5.4).
549 frontend / 421 Python green.
