SOTA iter 2 (cron c40dab4a tick 2). The §D-workaround that v0.6.6 left
on TX-only soak coverage is now empirically complete end-to-end.
Parallel 60 s capture with COM9 (206ef117053c) + COM12 (206ef1170084)
both on default v0.6.7, no WiFi associations needed:
* RX rate cross-board:
- COM12: tx=301 rx=297 match=297 (98.7 %)
- COM9: tx=301 rx=300 match=300 (99.7 %)
- 0 TX failures on either side over 30 s of beacons
* Leader election fired for the first time in ADR-110:
+27336 ms COM9: "stepping down: heard lower-id leader 206ef1170084
(we are 206ef117053c)" — the lowest-EUI-wins protocol the original
c6_timesync was designed to run, now actually working because the
transport is healthy.
* Cross-board sync offset converged and stable:
COM9 offset_us: -1462 -> -950 -> -954 -> -957 -> -948
±10 µs jitter once leader-following stabilises, hitting the ±100 µs
target named in ADR-110 §2.4.
802.15.4 c6_ts path stayed rx=0 across both 60 s captures — D1 still
broken in IDF v5.4, exactly as documented. ESP-NOW is confirmed as the
working multistatic time alignment transport.
