Julien Calixte 5540f901de docs(sd): mark SD-on-SPI3 verified on hardware
Re-ran the spike on the dedicated SPI3 wiring (CLK 14 / MOSI 15) with
the same clean mount + atomic round-trip result. Flip the docs from
"pending a re-run" to verified.

Postmortems

Bench + bring-up debugging write-ups: what broke, how we found the root cause, and the decisions that came out of it. One file per incident, named YYYY-MM-DD-<slug>.md. These capture why a spike stalled or a design turned — the kind of context that's expensive to reconstruct later.

Project overview: ../../README.md. Bring-up spikes: ../v0.1-mvp-technical.md.

Date Incident Status
2026-07-05 Spike 3 (SD) — card rejects CMD59 (SPI-mode CRC) Paused — awaiting a compliant microSD; wiring + firmware proven
2026-07-05 Spike 7 (git push) — ADR-004 kill-switch fired: gix can't push over HTTPS Turned — pivoted to libgit2; git mechanics proven on desktop, device build next
