RESIGN_REQUIRED

The assigned relayer can no longer be used, so the transaction must be signed once more.

HTTP status	409
Group	Relay path
Retryable	No — sending it again changes nothing
Re-sign	NEW_SIGNATURE_SAME_NONCE — one new signature, same nonce, new relayer

What happened

The relayer is no longer renewable, or its exposure headroom or hourly signing budget is spent on every host that holds its key. Nothing was signed or broadcast.

What to do

Take the new relayer from the assignment member, rebuild the transaction with the same nonce, and have the user sign it — once.
