witness: ESP-NOW 300 s soak — 2951 tx 0 fail (2.5x sample) 

Confirmation run vs the earlier 120 s soak. Same firmware, same board,
longer window:

  Captured 67307 bytes over 300 s
  ESP-NOW samples: 60
    first: tx=1    fail=0 rx=0 match=0 leader=1 offset=0
    last:  tx=2951 fail=0 rx=0 match=0 leader=1 offset=0
    TX rate: 9.83/s (target 10/s)
    TX failure rate: 0.0000%
  app_main calls (reset detector): 1  -> no crash

2.5x sample size, identical zero-failure rate, marginally higher
sustained rate (9.83 vs 9.60) — FreeRTOS timer settling. Adds a second
data point to WITNESS-LOG-110 §D-workaround.

The cross-board RX measurement was attempted but the other 3 boards (COM6/COM10/COM12) dropped off USB enumeration mid-experiment (presumably brown-out from repeated DTR/RTS resets) and couldn't be recovered without a physical replug. **Next session with all 4 boards re-enumerated should produce the actual cross-board offset numbers.** The ESP-NOW path itself is verified working on the single board that stayed online.
