libfreemkv must stay firmware-clean for crates.io. Move ALL drive-unlock
knowledge — firmware blobs, WRITE_BUFFER/MODE SELECT upload, unlock CDBs,
the MT1959 variant-A/B handshake, the 800 KB profiles.json database, and
the DriveProfile parsing — out into the freemkv-unlock-ld crate.
libfreemkv now keeps only the seam:
- Unlocker trait (name/matches/unlock) + a process-wide ordered registry
(register_unlocker / route_unlock) in src/unlock.rs
- Drive::init() walks the registry; the first unlocker whose matches(id)
is true runs unlock(scsi, id); if none match the drive is left in
stock mode and the host-cert AACS handshake (the OEM route) carries
the disc.
The unlocker issues its own CDBs through the public ScsiTransport::execute,
so libfreemkv knows nothing about how unlocking happens.
Removed:
- profiles.json
- src/platform/mt1959/{mod,variant_a,variant_b}.rs
- src/profile.rs (DriveProfile, ProfilesFile, find_by_drive_id, ...)
- the PlatformDriver trait
Because the Unlocker seam reports only success/failure (no extended-access
marker), VID acquisition is now always via the cert-based handshake; the
per-drive OEM-VID-CDB shortcut and Drive::is_unlocked() (now const false)
are removed/neutralized. Disc-speed calibration moved into the unlocker's
unlock(); Drive::probe_disc() is a no-op.
git grep over src/ is firmware-blob/profiles/WRITE_BUFFER/mt1959-free.
All tests pass on Rust 1.86 (precommit green).
