Python ESP32BinaryParser was using struct format '<IBBHIIBB2x' — the
'2x' skipped bytes 18-19 as reserved. After the Rust-side decoder was
extended to surface PPDU type + flags, the Python pipeline (which
archive/v1 still uses for testing + the proof verifier) needs the same
update so its consumers see the HE metadata too.
csi_extractor.py:
- HEADER_FMT now '<IBBHIIBBBB' (captures bytes 18-19)
- New metadata fields: ppdu_type ('ht_legacy'|'he_su'|'he_mu'|'he_tb'|'unknown'),
ppdu_type_raw, he_capable, bw40, stbc, ldpc, ieee802154_sync_valid,
adr018_flags_raw
- Class constants PPDU_HT_LEGACY..PPDU_UNKNOWN mirror the firmware
test_esp32_binary_parser.py:
- build_binary_frame() takes optional ppdu_byte + flags_byte (default 0)
- New TestAdr110ByteEncoding class with 5 tests:
- Pre-ADR-110 zeros decode as 'ht_legacy' + all-flags-false
- HE-SU / HE-MU / HE-TB decode correctly
- 0xFF decodes as 'unknown'
- All-flags-set round-trip (0x1D)
11/11 parser tests pass (6 existing + 5 new). Backwards compat verified.
Pairs with the Rust-side decoder in commit 3959fabf3. Both pipelines now
read the same wire format produced by the C6 firmware's
CONFIG_CSI_FRAME_HE_TAGGING path.
