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. UUIDs.Strings converts a slice of UUIDs into a slice of 36-character hyphenated UUID strings in matching order
  2. UUIDs.Strings on a nil UUIDs slice returns an empty string slice
  3. UUIDs.Strings on an empty non-nil UUIDs slice returns an empty string slice
  4. UUIDs.Strings preserves uuid.Nil formatted as the standard 36-byte zero UUID string
  5. UUIDs.Strings output strings round-trip with uuid.Parse to recreate the original UUID slice
