M1 + M2 hardware-verified 2026-06-14 (Waveshare ESP32-P4-ETH)

First end-to-end bench verification. Board is the Waveshare
ESP32-P4-ETH (Amazon B0FN7JQ2V8), 32 MB PSRAM, 32 MB flash silkscreen,
ESP-IDF v5.4.1. No panel attached, just board on USB power + LAN.

What passed
-----------
M1 — Ethernet driver up; DHCP lease landed at 10.0.13.83 (gw
10.0.13.1, netmask 255.255.255.0). MAC e8:f6:0a:e0:90:94. 31.7 MB
PSRAM free. Boot completes in ~4s after the kernel handoff.

M2 — GET http://10.0.13.83/state returns the full spec JSON shape
(name=null, configured=false, state=unconfigured, resolution=480x800,
ip=10.0.13.83, free_heap=520995, free_psram=31730048, all counters at
0). mDNS browse from macOS (dns-sd -B _scrypted-viewport._tcp local.)
finds one instance named "viewport" within ~100ms.

Bare-board behavior (Ethernet unplugged) verified too: boot completes
cleanly with summary line `boot complete — subsystems [EMHdJ-B]
ip=(no link)`. Lowercase d = display down because no panel attached;
- for touch because it shares the panel I²C bus.

README status snapshot updated to reflect M1+M2 ✅ on hardware;
TESTING.md M1 and M2 sections gain the 2026-06-14 verification note
plus the three fixes that bring-up exposed (RXD0/RXD1 swap, mDNS
hostname order, elegant subsystem degradation — already shipped in
commit 220ee4c).

-> Combined hardware verification of M1+M2 is fine — they both run from the same flash session.
+**Status**: ✅ verified 2026-06-14 on Waveshare ESP32-P4-ETH (Amazon B0FN7JQ2V8, 32 MB PSRAM, 32 MB flash silkscreen, IDF v5.4.1). DHCP lease landed at 10.0.13.83. Three fixes were needed during bring-up — see commit 220ee4c:
+> 1. **RXD0 / RXD1 GPIO swap**: ESP32-P4 EMAC iomux fixes RXD0=29, RXD1=30. The original pin map had them transposed.
+> 2. **mDNS hostname order**: `mdns_service_add()` returns INVALID_ARG if hostname isn't set yet. Now init → hostname → service_add → TXT.
+> 3. **`app_main` best-effort everywhere**: any one missing subsystem (no LAN, no panel) used to abort the boot. Now each is independent; final log line summarizes which letters of `EMHDJTB` came up.
