The cost of making things has collapsed. The cost of blindly trusting them went up.
Tashika — the legibility gauge for AI-generated work.
It measures whether AI-generated work holds up — and whether anyone still understands it.
Production runs on one clock. Comprehension on the clock it always was.
One through-line: measurement. Everything we build reads a legibility state and watches it for drift.
Three things happened, in order.
Generation got cheap.
Anyone can produce a draft, a design, a whole system in seconds.
Verification became the bottleneck.
The slow, expensive step is no longer making the work. It's confirming the work is right.
Comprehension is what no one measures.
A team can ship work that passes every check and that no human actually understands. The gap stays invisible until something breaks.
Three quantities, read at every layer.
Legibility: whether what your systems do is written down anywhere, and whether anyone still knows it. It isn't one number — it moves on three axes, and they move independently.
How much of the work is pinned to something checkable.
What neither captures. We report it as a bound, never as zero.
Everything we build watches for one thing — drift: work quietly diverging from the verified state it began in.
We write the argument out in full. Read it when it lands.
