pub fn classify_403_auth_block(
req: &ProbeDefinition,
res: &ResponseSurface,
) -> Option<AuthBlockSignature>Expand description
Classifies a 403 response. Returns Some only when an auth-layer signal is present —
WWW-Authenticate header or insufficient_scope / invalid_token body. Otherwise
returns None so the 403 propagates as potential oracle evidence (BOLA / IDOR territory).
