Forecasting Without Prophecy: a plain-text discipline

Back to notes I am a fire Aries ruled by Mars, and even I will not pretend the future is a thing you can read off a chart. Calibrated uncertainty does the work prediction promises. The difference shows up six months later, when you can still grade wh...

The Boundary That Makes iOS Capture Safe on the Web

When raw capture data lies The first time I compared a crop from a different source resolution, the box looked right until I did the math. The coordinates were being treated as if every image had the same pixel grid, and that assumption quietly poiso...

Phase 2 Calibration: Per‑Category OOD Thresholds + Group‑Relative Reward Normalization in My Scene Compiler

I didn’t add per‑category OOD thresholds because it was academically elegant. I added them because my baseline runs were telling me the same story over and over: some prompt categories were systematically getting mis-gated by a single global uncertai...
