What are mint and freeze authority?
Mint authority is the on-chain permission to create more of a token; freeze authority is the permission to freeze holders' balances. If these stay active, the owner can dilute or lock holders.
Safer tokens usually have mint and freeze authority revoked, so the supply is fixed and balances cannot be frozen. Active authorities are a red flag worth checking on a block explorer.
These are contract-level properties rather than market signals, so they sit in PumpScore's planned factor framework.
