There was a problem hiding this comment.
LGTM.
Persistent CMP dictionary values now correctly survive between runs, maybe it would worth to benchmark.

Stacked on #15814.
This PR moves transaction and sequence generation into
foundry-evm-fuzzbehind concreteTxGenerator,FuzzState,SequenceGenerator, andSequencePlantypes. Stateless fuzzing uses a fixed depth-one plan, while invariant fuzzing retains isolated worker feedback, lazy target discovery, and lazy sequence continuation.The existing execution loops remain separate. Corpus persistence and replay stay in the executor crate, while sequence and ABI/CMP mutation move into the fuzz crate. There is no implicit funding behavior or on-disk format change.
This is the second staged PR because the shared input pipeline must exist before execution campaigns can be unified. Commit, check, replay, shrinking, scheduling, and result semantics remain deferred to PR 3.
