| Where | I believed | Then I measured | So I |
|---|---|---|---|
| BeatMind, GPU | The GPU was doing the work | It had silently fallen back to the CPU. One missing library, libcublasLt.so.13 |
Fixed it. About a minute became 23 seconds (two different tracks, so "about") |
| BeatMind, rights | A tick box saying "I own this" is enough | A checkbox is not a rights check | Deleted it. Export now needs a fingerprint match |
| BeatMind, billing, 2026-09-20 | Refunds on a downgrade were fair | They refunded cash for credits already spent | Found it fact-checking one sentence for a client. Fixed the same day |
| Vivid, speed | A "turbo" model, 5.9× cheaper, was a win | Faces got worse and people were duplicated | Did not ship it |
| UPI Fraud Engine, Jan 2026 | 0.9106 ROC-AUC, ready to go | A column that only existed in my synthetic data matched the label 100% | Removed it and retrained. 0.8953 is the honest number |
| QueryPilot | A hallucination rate of 100% | My detector was reading dictionary keys, not table names. The real rate was 0% | Fixed the detector |
