The best thing our engine does is refuse to answer
Why we deleted a feature so TRONORIGIN would stop naming a controller when it has no evidence — and how a benchmark caught it guessing on 13 out of 13 accounts.

Field Notes
Practical write-ups from real projects — AI, crypto engineering, and the things we learned building them.
