Raises the Nexmon path from a normalized record format to parsing what the patched Broadcom firmware actually emits, end to end. napi-c shim (ABI 1.0 -> 1.1, additive): - rvcsi_nx_csi_udp_header / rvcsi_nx_csi_udp_decode — parse the real nexmon_csi UDP payload: the 18-byte header (magic 0x1111, rssi int8, fctl, src_mac[6], seq_cnt, core/spatial-stream, Broadcom chanspec, chip_ver) + nsub complex CSI samples (modern int16 LE I/Q export — what CSIKit/csireader.py read for the BCM43455c0 / 4358 / 4366c0; nsub = (len-18)/4). rvcsi_nx_csi_udp_write to synthesize payloads for tests. rvcsi_nx_decode_chanspec — d11ac chanspec -> channel (chanspec & 0xff) / bandwidth (bits [13:11], cross-checked against the FFT size) / band (bits [15:14], cross-checked against the channel number). Still allocation-free, bounds-checked, structured errors, never panics. - ffi.rs wraps it: decode_chanspec / parse_nexmon_udp_header / decode_nexmon_udp / encode_nexmon_udp + DecodedChanspec / NexmonCsiHeader; every unsafe block documented; the ABI guard now expects 1.1. rvcsi-adapter-nexmon: - pcap.rs — a dependency-free classic-libpcap reader (all four byte-order / timestamp-resolution magics; Ethernet / raw-IPv4 / Linux-SLL link types; tolerates a truncated final record; pcapng is a follow-up) + extract_udp_payload + a synthetic_udp_pcap / synthetic_nexmon_pcap test/example generator. - NexmonPcapAdapter (a CsiSource) — reads the CSI UDP packets out of a `tcpdump -i wlan0 dst port 5500 -w csi.pcap` capture, decodes each via the C shim, stamps the frame timestamp from the pcap packet time; non-CSI packets counted as "skipped" in health. rvcsi-runtime: decode_nexmon_pcap, summarize_nexmon_pcap (+ NexmonPcapSummary: link type, CSI frame count, channels, bandwidths, subcarrier counts, chip versions, RSSI range, time span), CaptureRuntime::open_nexmon_pcap[_bytes]. rvcsi-node (napi-rs): nexmonDecodePcap, inspectNexmonPcap, decodeChanspec, RvcsiRuntime.openNexmonPcap. @ruv/rvcsi SDK + .d.ts updated (NexmonPcapSummary, DecodedChanspec). rvcsi-cli: `record --source nexmon-pcap`, `inspect-nexmon`, `decode-chanspec`. 161 rvcsi tests pass (adapter-nexmon 9->22), 0 failures, clippy-clean. ADR-096 §2.2/§2.3/§5, CHANGELOG, CLAUDE.md updated. https://claude.ai/code/session_01CdYAPvRTjcch6YrYf42n1z
