Functions
Result< std::array< unsigned char, 32 > >	purify::accountable::nonce_evaluation_input (const ConflictContext &context, purify_secp_context *secp_context)
	Derive the candidate deterministic Purify input from the registered slot.
Result< FieldElement >	purify::accountable::signature_challenge (const ConflictContext &context, std::span< const unsigned char > canonical_body, purify_secp_context *secp_context)
	Compute the versioned Q/U/T/body challenge, without a nonce point.
Result< std::array< unsigned char, 33 > >	purify::accountable::reconstruct_nonce (const ConflictContext &context, std::span< const unsigned char > canonical_body, const ScalarSignature &signature, purify_secp_context *secp_context)
	Reconstruct the full nonce point as sigma*G - e*Q, rejecting infinity.
Result< std::array< unsigned char, 32 > >	purify::accountable::recover_same_slot_key (const ConflictContext &context, std::span< const unsigned char > first_body, const ScalarSignature &first_signature, std::span< const unsigned char > second_body, const ScalarSignature &second_signature, purify_secp_context *secp_context)
	Recover the exact signing scalar exposed by two same-slot responses.
