CWR error: The header doesn't say what kind of sender you are
What it means
The header's sender type says what kind of party you are (PB publisher, SO society, AA agency, WR writer). A value outside that list makes receivers distrust the whole file.
How to fix it
Use the two-letter code for your role — for most publisher-side senders that's PB.
