_A Mac with Apple silicon doesn’t permit native arm64 code to execute unless a valid signature is attached. This signature can be as simple as an ad hoc code signature (cf. codesign(1)) that doesn’t bear any actual identity from the secret half of an asymmetric key pair (it’s simply an unauthenticated measurement of the binary)._

_For binary compatibility, translated x86_64 code is permitted to execute through Rosetta with no signature information at all. No specific identity is conveyed to this code through the device-specific Secure Enclave signing procedure, and it executes with precisely the same limitations as native unsigned code executing on an Intel-based Mac._

Maybe it's Rosetta bins? - src from Apple:
