Public interactive demo · regression memory for AI coding agents

Evidence that
survives the agent.

Coding agents can edit code and run tests. Issue2Proof adds durable, executable memory of failures that were already fixed—and replays that evidence before related changes ship.

The missing layer

Rules tell an agent
what to remember.

→

Issue2Proof preserves
what was verified.

One failure becomes future protection

A closed evidence loop

Model confidence never becomes proof by itself. Each important claim is connected to execution.

01

Learn

Reproduce the original failure in a disposable Nebius Sandbox before accepting a repair.

Investigation →02

Remember

Freeze the behavioral claim, regression, hashes, assumptions, boundaries, and provenance.

Memory Capsule →03

Replay

Recall the capsule inside any agent or pull request, then audit the proposed revision independently.

Not another coding interface

Keep the agent.
Add an evidence memory.
