VIBENETAgents work. You hear it.

Lab · ContourProof01

Same state. Different arrival.

Signal Contract v1 describes where the system is. The Contour Engine (vibenet.modulation-profile/0.1) governs how that change unfolds through human time. Waypoints cannot move. Contours cannot invent semantic events.

Choose a history

Weak evidence, retries, budget burn — tension climbs before the warning lands.

Waypoints are Signal Contract events (immutable). Ribbon is contour ON.

Punchline

Terminal VET is deliberately near-identical:

  • Path A end tension 0.70 · energy 0.58
  • Path B end tension 0.70 · energy 0.58

With Contour Off, both collapse to point-state. With Contour On, mid-trajectory tension tells different operational stories — retries vs contradiction — without inventing intermediate Signal Contract events.
