Compliance Vectors

The 8 non-negotiable baseline test cases.

To be considered a compliant implementation of the Stellar Address Kit, a package must pass these 8 critical “canary” vectors.

Case	Why it matters
2^53 + 1 Canary	Verifies that the implementation does not lose precision on large IDs.
uint64 Max	Ensures 18,446,744,073,709,551,615 is handled as a string.
uint64 Overflow	Confirms that IDs larger than 64-bit trigger an error.
Lowercase Input	Verifies that addresses are normalized to uppercase in the output.
NOTANADDRESS	Ensures malformed strings return INVALID_CHECKSUM.
Tampered Checksum	Confirms that modifying one character in an address triggers an error.
C-Address Destination	Ensures contracts are flagged as INVALID_DESTINATION for routing.
Invariant Check	Verifies that if an error is present, all other result fields are empty.
