inventory() parses both response formats: slots=1 -> single tag dict (or None); slots=16 -> list of tags from the iso15_inventory_response_t anti-collision struct, each CRC15-validated. Optional request-level AFI filter and client-side DSFID filter. One 16-slot round drops colliding slots (full tree-walk resolution is a follow-up); scan() stays the single-tag convenience.

The sync REPL proxy forwarded methods via __getattr__, so dir()/tab-completion never saw them and the sync wrapper reported (*args, **kwargs) instead of the real signature. Add __dir__ delegating to the wrapped target, and decorate the async wrapper with functools.wraps so inspect.signature()/help() report the real params + docstring.

lf.tune sends the 2-byte {mode,divisor} the firmware requires (was 3 -> EINVARG/0V). t55.writebl packs the 10-byte {data,pwd,blockno,flags} struct with a single bit-packed flags byte (was 12). t55.wakeup packs 5 bytes {pwd,flags}. t55.config is maintained client-side (firmware has no GET). LF_SAMPLING_SET_CONFIG uses send_ng_no_response (firmware never replies). Pre-existing, independent of the rebase.
14a.sim sent a MIX frame but the handler is NG casting a packed {tagtype,u16 flags,uid[10],exitAfter,rats[20],ulauth...} struct -> whole struct garbled, flags never arrived. Rewrite to send_ng with the exact struct and expose tagtype (2=Ultralight,7=NTAG) so Ultralight/NTAG sim works. 14a.sniff sent MIX (args stripped -> empty asBytes); send NG with the 1-byte param. Pre-existing, independent of rebase.

dropfield waited on a reply the firmware never sends (bare hf_field_off();break;) -> 2s stall + raise; use send_ng_no_response. hf.sniff under-sent the 10-byte {u32,u32,u8,u8} struct and mis-parsed the uint16 reply. hw.standalone sent an empty payload for a {arg,mlen,mode[10]} struct and blocked; pack it + fire-and-forget. Pre-existing, independent of rebase.

wrbl padded key to 16 (firmware reads block at asBytes+10) -> corrupt writes; pad to 10. nested sent {block,keytype,key,target...} but firmware struct is {block,keytype,target_block,target_keytype,calibrate,key[6]} -> attacked wrong target; reorder + add calibrate + decode reply. cident/sim sent empty/MIX payloads for NG handlers -> send the packed structs. mf.sniff (no firmware handler) reroutes to CMD_HF_ISO14443A_SNIFF. Pre-existing, independent of rebase.

ISO15_READ_RESPONSE was 0x10 but the firmware bit is 0x20 (0x10 is HIGH_SPEED, which pm3py lacked), so scan/rdbl/wrbl sent flags 0x19 with READ_RESPONSE never set -> firmware never listened and replied empty. The ARM firmware also ignores ISO15_APPEND_CRC (the C client adds the CRC host-side via AddCrc15), so pm3py's CRC-less frames were never answered by a real tag.
Fix flag values to match firmware include/iso15.h, add crc15 (CRC-16/X-25), and route all iso15 commands through _iso15_payload (appends CRC, sends CONNECT|HIGH_SPEED|READ_RESPONSE=0x31). Payload now byte-matches the C client getUID. Pre-existing bug, independent of the firmware rebase.

CMD_MEASURE_ANTENNA_TUNING_HF requires a 1-byte mode arg (firmware rejects length!=1 with EINVARG) and returns the voltage as uint16, not uint32. tune() sent no arg (empty reply -> 0 mV) and parsed <I. Now sends mode 1/2/3 (START/MEASURE/STOP) and parses <H. Verified vs firmware appmain.c handler; C client reads the same ~15V on this firmware.

Merges the package refactor (core/ sub-package, normalized naming,
scaffolded sub-packages) while preserving all in-progress sniff
infrastructure. Git rename detection carried WIP changes to new paths.

In-progress work — committing before refactor merge so git rename
detection can carry changes to new file locations.

Phase 1 of package refactor. Moves all source modules into pm3py/core/
with file renames (hf_14a→hf_iso14a, hf_15→hf_iso15, hf_mf→hf_mfc)
and client attribute normalization (hf.a14→hf.iso14a, hf.mf→hf.mfc).
pm3py/__init__.py re-exports from core for backward compat.
