The verification must be unbounded---it must hold for slices of arbitrary length.
The verification must hold for generic type T (no monomorphization).
All proofs must automatically ensure the absence of the following undefined behaviors ref:
- Accessing (loading from or storing to) a place that is dangling or based on a misaligned pointer.
- Reading from uninitialized memory except for padding or unions.
- Mutating immutable bytes.
- Producing an invalid value
Note: All solutions to verification challenges need to satisfy the criteria established in the challenge book in addition to the ones listed above.
