FSK_PCM at 12.5 us/bit, CRC-16 (poly 0x8005, init 0x0000). Ported and
independently re-verified from an unmerged fork (hakong/rtl_433,
feat-typhur branch) referenced in the issue: re-derived the sync word
and payload location via raw bit search (not trusting the fork's own
CRC self-check), confirmed CRC valid on all 19 real captures across
two physical probes, and confirmed the decoded values are physically
sane -- T1-T5 and ambient temperatures match the reporter's own noted
ranges, battery voltage is stable per probe, and the counter
increments monotonically per probe ID.
