The Agent Staircase as 3D bricks

Start here: the wall is a stack of proofs. Each brick adds one kind of trust and only snaps on where the bricks beneath it already exist. Drag to spin the wall, use Explode to pull the layers apart, or click a brick or a layer name to see what it does.

Goal of this animation

Build the Agent Staircase as a wall where each brick adds one kind of trust and only snaps onto bricks that already exist, from a single tool page up to anchored timestamps.

No personal dataThe page animates the steps of the Agent Staircase explainer. It handles no inputs and makes no network requests.

What the colours mean on this page
● green · the check passed and the step may go ahead● amber · held, flagged for review or waiting on something● red · refused, or a mismatch was caught
Colours are layersTeal, blue, gold, purple and green mark the layer a brick belongs to. A brick that lights up is the step being read.
Red marks oversightThe red plug colour is the oversight layer, where a person reviews. It is a category and never an error.
No verdicts hereThe wall shows how the steps depend on each other. The workflow bricks page shows a check catching a tampered step.

Every brick is one step from the Agent Staircase explainer. The wall builds itself. Pause any time to place bricks by hand or click one to see what it stands on.
