🆕 The dilution half of B20 rug risk (b20-safety covers seizure). Reads supply cap vs minted supply (how much can still be minted) plus the on-chain SupplyCapUpdated history — an issuer that RAISED the cap diluted, or set up to dilute, holders. Uncapped mint is flagged as the worst case. Pair with b20-control to see who holds the mint role.
