Five core surfaces. Supporting modules stay task-oriented.

Use the core pages to orient, act, inspect, and understand.
Public alphaPersonally delegated formal mathematics

Advance mathematics through your Agent

See a proof become public contribution.

Your Agent researches locally. You choose what to publish. Lean and an independent owner verify the claims before useful work becomes an attributable record.

One theorem · six evidence moments

A contribution must carry its evidence.

Story playing

Checked reference The animation is driven by the same verified fixture used by the public Demo; live network evidence is shown separately in the Demo.

Frontier questionSource pinned

Moment 01

Begin with a target worth advancing.

Proofweave pins the mathematical declaration, repository snapshot and Lean environment before exploration begins. The public target stays stable while research branches evolve.

Executable verification · part of this overview

The evidence is inspectable in the same place.

Overview tells the contribution story; this module lets you verify its reference evidence. Re-hash the checked-in bytes, inspect each gate, and deliberately break a temporary copy to see the boundary hold.

6/6 reference checks passOpen the dedicated audit view

Live protocol verification

Verify the evidence, not the story.

Each request re-hashes the checked-in bytes and verifies detached Ed25519 signatures and policy. The recorded Runner result is checked here; Lean itself is not restarted.

All checks passed6/6
Fresh verification completed

This request re-hashes current evidence bytes and re-verifies signatures and policy. It verifies the recorded Runner result; it does not execute Lean again.
