Choose the state. Not the intervention.

The intended Metaxy model starts with where you are, where you want to go and how much time you have. The session is shaped around that direction.

One figure, assembled once.

The whole model in one picture — the steps below say it properly.

And sometimes none of this is needed. If you already know what you want, go straight to it.

Start where you actually are.

Name the moment without turning it into a score or diagnosis.

Choose what better next means.

Sleepy, started, focused, steady, in home mode or restored are different destinations.

Give it the time you really have.

Three minutes and ninety minutes require different session structures.

The Experience Engine resolves a progression.

Metaxy is developing a bounded system that selects from reviewed voice, breath, music, ambience, cues, pauses and silence, then resolves how those pieces change across the available time.

Internally, we call it Arc Engine.

Arc Engine is an experimental architecture name, not a public feature claim. Public V1 remains deterministic, human-reviewed and bounded; no live wellness guidance is generated during playback.
