Firmware's been done for months. The board hasn't.

On the bench

• SpotOn blocked

  An nRF54L15 sensor node on Zephyr, sampling one ICM-42688-P at 1kHz and pulling modal features out of the impact window on-device.

  Firmware and app are code-complete: FLASH 251,724 B, RAM 159,451 B, behind a CI gate that fails on 2% drift.

  One milestone out of 87 is blocked, and it is the board order itself. Routing came back from the vendor this week at 0 unrouted and LVS pass, so there is a DRC-0 candidate. Three rework items went back.

  

  

  

  

• harness-maker shipping

  v0.45.1. The thing that reads a repo and builds that repo its own agent harness. 47,986 lines, 5,645 tests, 174 SPECs.

  This month it turned out the review auto-fix loop was reproducing defects at roughly 1:1. Nine of thirty findings were introduced by an earlier round’s own fix. It now re-derives the model before it batches.

• EmbedEval published

  v0.2.0. 267 firmware cases across Zephyr, ESP-IDF, STM32 and Yocto, scored through five layers that end in a real cross-compile.

  Sonnet 5 scored 67.0% pass@1 against Sonnet 4.6’s 68.0%. On the 232 cases both models saw, that is 0.9 points down, which is a tie. A model generation went by with no measurable gain on embedded firmware.
