Agentic Validation · server-evaluated · privacy-first

Verify interaction consistency, not identity.

This challenge sends one short-lived movement trajectory to Nessco so the server—not browser-supplied summary values—can look for automated timing, perfectly linear motion, repeated steps, and implausible placement. It actively estimates bot risk, but does not prove identity, guarantee humanness, or replace accessible authentication.

  • Scored server-side
  • Raw samples are ephemeral
  • Keyboard path included
LIVE / LOCAL

Move the piece into place.

Pointer, touch, and keyboard input are measured only while this challenge is active. A bounded trajectory is submitted once for in-memory bot-risk scoring; it is never added to browser storage or returned by the API.

CHALLENGE / 01

Horizontal puzzle slider

Loading randomized puzzle…

Pointer or touch: drag the shaped slider left or right and release it over the matching cutout. Vertical movement is ignored. Keyboard: focus the piece, use Left and Right arrows, then press Enter to place it. Home and End jump across the track; Escape restarts this puzzle.

The raw trajectory is sent only to the same-origin verification endpoint, scored in memory, and then discarded. Only the aggregate risk result is returned.

Ready. Choose any supported input method.

NESSCO PRO + MAX

Integrate the signal with explicit policy.

The randomized, server-scored puzzle provides a human-interaction signal for policies that protect credit-consuming agent actions. Backend workspace password access is separate: the server-managed NESSCO_PASS can be entered directly with or without GitHub. A correct password grants workspace access; administrator identity still comes only from verified account claims.

  • Fail-open or step-up policy remains yours.
  • Accessible alternatives are required.
  • Raw interaction samples should remain ephemeral.
