Frame JSON Schema

The downloadable JSON Schema validates the raw ASCII frame envelope:

  • Literal { and } boundaries.
  • Two uppercase command characters.
  • Comma-separated printable ASCII content.
  • Four uppercase hexadecimal CRC characters.
  • A conservative maximum frame length.

After envelope validation, select the command-specific field order from the command catalog JSON, then verify CRC with the authorized PW suffix.

JSON Schema cannot prove physical behavior or authorization. It must be followed by field, CRC, message-ID, order-state and role/scope checks.
