The build log
Field notes
from the garage
What actually happened while building PONNE — post-mortems included. Written when there is something worth saying, not on a schedule. RSS.
Post-mortem · 2026-07-25
My own app took me out of the Spa 12 Hours
Hour nine of a 12-hour team race: a button-capture bug spammed iRacing until my USB devices dropped and I lost the wheel mid-stint. The four defences that came out of it.
Post-mortem · 2026-07-25“Revoke device” didn’t revoke anything
The revoke button deleted the device but left its 30-day token alive. What broke, how a review pass caught it, and the test discipline that came out of it.
