Key Observations

• supportedstandards is ["NEP-17"] — the compiler detected all five required methods and the Transfer event.
• permissions includes StdLib.serialize and CryptoLib.keccak256 — these are required by the mapping storage access pattern, not by any explicit cross-contract call in the source.
• trusts reflects the NatSpec override, restricting callers to the NEO native contract.
• safe: true on symbol, decimals, totalSupply, and balanceOf because they are pure or view functions.
• extra merges compiler defaults with NatSpec overrides. The Author field is overridden by the NatSpec tag.
