- identify clears the previous field/protocol/transponder up front, so
consecutive identifies (esp. when swapping tags) never show stale data.
- LF identify: probe a T5577 by reading config block 0 (lf.t55.readbl(0)).
A valid config confirms the T5577 and, decoded via T5577Config, names
what it's emulating — "T5577 (EM4100 / EM4102)", "T5577 (HID Prox)", etc.
(exact-word map, else modulation family). Tightly gated (status ok,
non-trivial config, known modulation, sane max_block) so no-tag reads
don't false-positive; lf.search() couldn't do this without demod.
- format_summary shows the config word for LF (no UID).
4 tests (T5577 emulation report, no-T5577, stale-clear).
