An unlocker removes a drive-level bus-encryption barrier so the drive serves readable (de-bus'd / de-scrambled) sectors. Content-key decryption is a separate concern — the consumer's job.

This crate defines the Unlocker contract and a generic SCSI transport contract, and holds the self-contained unlocker modules. The consumer (libfreemkv) depends on this crate and dispatches through all_unlockers(); it never names an individual unlocker, and clients of libfreemkv are oblivious to unlockers entirely (as they are to the SCSI layer).

for u in freemkv_unlock::all_unlockers() {
    if u.matches(&ctx) {
        return u.unlock(&mut scsi, &ctx);
    }
}

To remove an unlocker, delete its module directory and its one line in all_unlockers() — nothing else changes.
