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. FormData appends text fields and generates standard multipart boundary
  2. FormData.getHeaders returns multipart/form-data content-type with boundary and merges extra headers
  3. FormData.hasKnownLength returns true for buffer and string fields and getLengthSync returns total byte length
  4. FormData.getBuffer returns complete multipart payload containing field names and values
  5. FormData appends buffer with custom filename and contentType options
  6. FormData.setBoundary sets a custom boundary string for stream and headers
  7. FormData.getLength asynchronously calculates total byte length matching getLengthSync
