#12: All 5 untranslated SpeckDL patterns now emit valid JS: - notIn → !.has(), old() → drop, union → Set spread, set diff → filter, append() → [...X, Y], length() → .length - ==/!= operator replacement fixed (word-boundary regression) - Postcondition object comparisons get @ts-expect-error TS2839 #11: Generator auto-detects opaque identifier types used in state variables and action params, emits 'type X = any' before class. - State properties use ! (non-null assertion) for strict mode TigerBeetleLedger → tsc --noEmit = 0 errors. 37/37 tests pass.
