M2 mesh status:
  M1 crypto: PASS on 3 ARM boards (X25519 + ChaCha20-Poly1305)
  M2 mesh: blocked by identical MAC on switch (documented)
  Workaround: loopback 3-node mesh on single board (tested, blocked by sshd hang)

Blocker for M2: identical MAC = switch can't route between boards.
Solution: per-board MAC in baked image (persistent) or USB-Ethernet adapter.

Documents the WORKING recipe proven 2026-07-07:
  - 5 SD card files (BOOT.BIN, uImage, DTB, ramdisk, uEnv.txt)
  - Boot switch QSPI/SD, USB power, Ethernet
  - SSH: sshpass -p analog ssh -o PubkeyAuthentication=no root@192.168.1.1N
  - Multi-board: ip addr add .11/.12/.13, then del .10
  - WARNING: ethaddr in uEnv does NOT propagate to Linux (DT MAC wins)
  - WARNING: do NOT delete .10 while SSH'd through it

3 boards confirmed alive simultaneously:

CRITICAL FINDING: P201Mini auto-detects SD card regardless of switch.
JTAG position + SD card = boots from SD perfectly.
Do NOT tell user to change boot switch for SD boot.

Board 1 death cause updated:
- NOT boot switch (was in JTAG, works fine)
- MMU stuck from JTAG experiments (ps7_init, kernel load)
- Recovery needs Vivado/XSDB or JTAG MMU disable

Proven recipe: vendor BOOT.BIN (2.9MB) + ethaddr change only
phi^2 + phi^-2 = 3

Comprehensive report covering 20+ hour session:
  P1: Boards dead (POR cleared, FSBL parks)
  P2: QSPI driver bug (W25Q256 vs N25Q256A)
  P3: JTAG DAP intermittent (adapter usb location)
  P4: MMU blocks DAP access
  P5: Identical MAC collision (6 fix attempts documented)
  P6: Kuiper vs Vendor BOOT.BIN
  P7: Board 1 JTAG MMU damage (permanent)
  P8: SD card wear (20+ cycles)
  P9: Boot switch irrelevant (Article VIII)
  P10: macOS limitations (raw disk, FTDI conflict, sshpass)

Solutions that worked + remaining blockers + tri CLI commands.

phi^2 + phi^-2 = 3

PROVEN on board 3 (2026-07-08):
  Boot switch in JTAG position
  SD card inserted
  → Linux boots from SD
  → MAC 02:00:00:00:00:03 (from uEnv.txt)
  → AD9361 detected, SSH works

Boot switch position is IRRELEVANT for SD boot on P201Mini.
BootROM auto-detects SD card presence regardless of switch.

Also updated:
  - Do NOT modify ramdisk (mkimage CRC issues)
  - sshpass needs -o PreferredAuthentications=password
  - Vendor BOOT.BIN = correct PL Ethernet (Kuiper = broken)

16-QAM core correct but modem clean FER 46.6% (vs QPSK 0%): amplitude decisions

Full-stack e2e test (encrypted video through QPSK+RS mesh, 2 nodes) + the timing
