A mark, not a metric

A metric is frictionless on purpose. Tap, log, move on. The ease is the product — the less you feel it, the more of it you'll do. But the things that change a person are rarely the things you don't feel.

Carving is the opposite. You drag a finger through sand and the grain resists, then gives. It takes a second longer than a tap, and that second is where the entry lands. You can't carve absent-mindedly. The gesture asks you to be there.

And a mark doesn't reset. A metric is built to be consumed — yesterday's number is noise the moment today's arrives. A mark stays where you left it. Come back enough times to the same rock and the sand around it wears in, worn the way a path wears across a lawn: not because anyone measured the crossings, but because you kept walking it.

That's the trade RITEN makes. Slower than a tracker, and heavier — on purpose. You're not feeding a graph. You're leaving a record, in your own hand, of having been here and meant it.
