ChallengeValidationError class

Base class for all challenge validation errors in SEP-0010 authentication.

Thrown when a challenge transaction received from the WebAuth server fails validation checks according to SEP-10 requirements. This ensures that clients only sign legitimate challenge transactions and protects against various attack vectors.

Challenge transactions must meet strict requirements:

• Must be ENVELOPE_TYPE_TX transaction type
• Must have sequence number of 0
• Must contain only ManageData operations
• Must have valid time bounds within grace period
• Must be signed by the server's signing key
• Must have correct source accounts for all operations
• Must include proper home domain and web auth domain values

Subclasses provide specific validation error types for different failures. Always validate challenge transactions before signing them to prevent signing malicious or manipulated transactions.
