Typing the page/block argument of a READ/WRITE now pops the identified tag's memory landmarks
as completions, each labelled with its datasheet role, so you pick a location by meaning:
READ( -> 0x00 UID / serial number
0x03 Capability Container (CC)
0x04 user memory
0xE3 CFG0 — MIRROR / MIRROR_PAGE / AUTH0
0xE5 PWD (32-bit password) ...
READ(0xE -> filters to the E-page landmarks
memory.landmark_pages() derives the notable pages from the same _LAYOUTS the hint/annotation use
(NTAG21x / Ultralight EV1 landmarks; T5577 blocks 0-7). The completer matches the partial in
0x-, bare-hex, or decimal form and inserts canonical 0xNN. A comma ends the page argument, so
data args get no page suggestions; tags with no known layout (MIFARE Classic) offer nothing.
Hardware-verified: completer run against a real identified NTAG216 lists 0x00..0xE6 with roles.
Tests for the map, partial filtering, second-arg guard, T5577 blocks, and the no-layout case.
1269 green.
