The variant-B firmware load hardcoded one drive's F1 vendor-verify token
and a fixed 0x9C0 firmware size. Across the 140 B drives the verify CDB
has 39 distinct per-drive values, and the real firmware length is encoded
in each drive's MODE SELECT CDB (2192..2528 bytes) — so the constants were
wrong for ~139 of 140 drives and truncated 13.
- DriveProfile gains fw_verify_cdb (the per-drive 0xF1 verify).
- variant_b uploads firmware.len() (now the correct per-drive size from
the regenerated profiles.json) and issues profile.fw_verify_cdb, falling
back to the const only for legacy profiles.
- profiles.json regenerated: 79 firmware fields corrected (13 truncated
recovered to full length, 66 over-reads trimmed).
- Adds a recording-transport regression test asserting the profile's F1
verify is issued (not the const) and MODE SELECT carries firmware.len().
libfreemkv owns the Unlocker trait + registry; this repo holds the concrete
unlocker plugins. LibreDrive moves to the ld/ member (package freemkv-unlock-ld
unchanged). Workspace root + repo README describe the general-unlocker model;
adding an unlocker = a new member + one register_unlocker line in the consumer.
libfreemkv dep is the crates.io version; local dev resolves it via the
gitignored .cargo/config.toml patch.
