One inspectable handoff
The route, the trace, and the proof stay together.
Intentrail turns a small synthetic mission into a record you can inspect, repeat, and pass on—without hiding execution inside a hosted service.
Every attempted cell, final cell, event, and stop condition remains visible.
Canonical digests and a replayable result travel in one portable receipt.
Visible state change
A command only counts when its outcome can be followed.
The simulator records where each step began, where it tried to go, where it ended, and why it stopped.

The motion mirrors deterministic state changes. It does not decide the result.

Clear by design
Evidence for a synthetic mission. Never a claim about a physical one.
Intentrail models a finite 2D route in the browser. It does not control hardware, authenticate sensors, certify safety, or broadcast transactions.

Make the next handoff inspectable.
Build a synthetic mission, run it locally, and leave the next person enough evidence to replay it.
