Firmware:
- fix(protocol): SNR type i8→i16 to match lora_phy PacketStatus
- fix(display): combine splash + waiting into one screen
- fix(display): move TX power to row 0 right-justified
- feat(display): sparkline distinguishes TX from RX — TX bars are dotted
(alternating pixel rows), RX bars are solid. TX-only slots show a short
marker. TX takes precedence over RX in the same time slot.
Host tool (tools/meshcore_rx.py):
- feat: full MeshCore packet decoder with colored ANSI output
- feat: GRP_TXT decryption using 276 channels from channels.csv
- feat: Watchman loop/collision reporter to #watchman
- feat: ADVERT-informed node registry with 12h TTL persistence
- feat: transport code fallback for older MeshCore firmware
- fix: robust error handling for long-running operation
- fix: collision detection uses evidence-based reasoning from advert cache
Channel directory (tools/channels.csv): 276 channels
Test corpus (corpus/): JSON Schema, 28 hand-crafted vectors, Hypothesis generator
Switch all ESP32-S3 boards from UsbSerialJtag to USB OTG CDC-ACM via
embassy-usb. The USB device stack is now shared code — boards only
provide the platform-specific embassy-usb Driver.
- Custom VID:PID 1209:5741 (open-source VID, "WA" PID)
- CDC-ACM class with proper device enumeration
- COBS+postcard protocol over CDC-ACM packet read/write
- Concurrent USB device loop + protocol loop via join()
- On disconnect: sends DisplayCommand::Reset to show "Waiting for host..."
- Justfile: espflash no longer uses --monitor (OTG steals PHY)
- Test script updated to detect by new VID:PID

- Fix CodingRate encoding: postcard uses 0-based variant index, not
repr(u8) value. CR 4/5 is variant 0, not 1.
- Shorten RSSI/SNR display line to fit 21-char width
- Python script auto-detects DongLoRa by USB VID:PID (303a:1001),
reconnects on device reset/disconnect, no more crash on RST

Protocol:
- SetConfig, StartRx, StopRx now send Response::Ok on success
(host was timing out waiting for acks that never came)
Display:
- Full frequency precision: 910.525MHz not 910.5MHz
- Full bandwidth labels: 62.5kHz not 62k
- RSSI/SNR row shows units (dBm, dB)
- Separator line moved down 3px to give RSSI/SNR breathing room
- Sparkline is now time-based: each bar = 1 second, scrolls left,
showing ~1 minute of RSSI history. Empty slots = no packets.
