Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. assert @babel/plugin-transform-destructuring exports a plugin factory function and AST helper methods
  2. assert array destructuring transforms indexed assignments, default values, hole skips, and rest elements
  3. assert object destructuring transforms property extraction, identifier renaming, default values, and rest properties
  4. assert nested destructuring patterns correctly unpack combined object and array structures
  5. assert destructuring in assignment expressions transforms existing variable targets
  6. assert function parameter destructuring correctly handles default parameter objects and unpacked arguments
  7. assert destructuring transformations support iterableIsArray and objectRestNoSymbols compiler assumptions
