Reproduce the break
Run the original tests in a fresh container to capture the actual runtime error.
AGENT RUSH / BLAST RADIUS ZERO
When dependencies break,
prove the fix.
Reproduce a supported failure, generate a scoped patch, and inspect the tests that prove the change. Explore Python, JavaScript, TypeScript, SQL, and compiled-language examples.

01 / HOW IT WORKS
From failure to evidence.
Change the failing call
Update the incompatible API while keeping the rest of the project and its tests intact.
Retest and inspect
Review the diff, before-and-after output, and the checksum of the unchanged tests.
02 / ARCHITECTURE
Follow the work.
Vultr Cloud Compute
The web API queues work and stores evidence. A separate worker controls execution and holds the model credential.
Vultr Inference
The configured coding model receives the failing test output and the relevant source. The server validates its proposed change.
Disposable Docker sandboxes
Each baseline, verification, and probe runs in its own container. The workspace shows its ID and cleanup result.
Measured on controlled examples.
GLM 5.3 Flash verified twelve repairs and rejected the seeded regression in the thirteen-profile model evaluation. Every outcome includes its candidate patch, test output, and provider receipt.

When would a team use VersionBridge?
Use it to investigate a failing dependency upgrade, compare test results, and hand a verified patch to a maintainer for review.
What can I repair?
Explore thirteen scoped examples across Python, JavaScript, TypeScript, Go, Rust, Java, C++, SQLite, and PostgreSQL. The public demo runs curated workloads. Compatible Python repository imports are available in private development mode.
Does it change my repository?
The patch applies to a temporary copy. Download the diff and decide whether to apply it to your project.
