MFC gets the same memory-map hinting as NTAG, at the block level:
block 0 manufacturer block — UID, BCC, SAK, ATQA, vendor data
sector trailer Key A [0-5], access bits [6-8] + GPB [9], Key B [10-15]
other blocks data block (sector N)
Handles 1K (16 sectors), Mini (5 sectors) and 4K — including the eight 16-block sectors 32-39
(trailer = last block, e.g. 143 = sector 32, 255 = sector 39). landmark_pages lists block 0 +
every sector trailer (the map skeleton; data blocks are uniform), so READ( / raw 30 surface it
in the completion dropdown. Also routes "MIFARE Mini" to the MFC catalog (was falling through to
Type 2).
Tests cover the block roles, large-sector trailers, bounds, Mini routing, and the dropdown map.
Path verified end-to-end with a mocked SAK-0x08 scan (identify -> catalog -> completer). Live
hardware verify still needs an actual Classic card on the antenna. 1339 green.
