Tashika
確か — certain, verified

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.

We measure the part everyone else assumes.

every weekthe gap between what you ship and what you can account for widens

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.

The shift

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.

The readout

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.

Behavior

How much of the work is pinned to something checkable.

Theory

Whether a human still holds the argument, the design, the reasons.

Residue

What neither captures. We report it as a bound, never as zero.

Legibility readoutBTR

Everything we build watches for one thing — drift: work quietly diverging from the verified state it began in.

The Ledger

We write the argument out in full. Read it when it lands.
