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 merge recursively merges properties of source objects into destination object
  2. assert merge recursively merges nested plain objects and arrays
  3. assert merge applies multiple source objects from left to right overwriting previous assignments
  4. assert merge does not overwrite existing destination values when source property is undefined
  5. assert merge mutates and returns the destination object directly
