Baseband (proc_flex.cpp): - Fix numeric vector field width (3-bit n+1 for types 3,4,7) - Fix capcode range classification for long address components - Add long address decode (Set 1-2, 1-3/1-4, 2-3) - Add vector checksum validation (4-bit nibble sum) - Add tone-only boundary detection via vector pre-scan - Add idle phase detection (skip all-zeros/all-ones before BCH) - Skip spurious TON for capcode 1 (BCH-corrected idle artifact) - Add BIW parsing: SSID1/SSID2, DATE, TIME, TZ, SYSMSG, CHAN - Add alpha fragment flags: frag, more_frag, seq, new, maildrop, sig - Add secure message enc= field (alpha/binary/separate) - Add numbered numeric flags: seq, new, fmt - Add HEX/Binary header decode: block_bits, new, maildrop, rtl - Add short instruction decode: temp group slot/target, sys events - Add short message (SMSG) decode: tone/numeric/source/numbered - Add group/temp-group/priority flags per address - Add S2 C-pattern detection with ±1 symbol boundary correction - Extract FIW roaming, repeat, traffic fields - Replace snprintf with lightweight str_* helpers (no heap/_sbrk) - Mark uncorrectable BCH words as ? instead of aborting phase - ETX/NUL handling: trim trailing padding, show mid-message as ? App (ui_flex_rx.cpp): - Add status bar: cycle/frame, bitrate, polarity, time, timezone - Add network info bar: LID, CZ, CC, roaming flag - Pipe-delimited serial output for all message types - BIW events to serial and status bar (not console) - Human-readable console: +GRP for temp group, G/TG/P flags - USB serial via UsbSerialAsyncmsg Packet (flex_defs.hpp): - uint64_t capcode (long address support) - 256-byte message buffer - Fragment flags, BIW raw values, address type, group/priority Known limitation: phase label unreliable on multi-phase modes (3200/2FSK, 6400/4FSK). Data always decodes correctly.
