You should be able to follow them.

A PATH YOU CAN FOLLOW

01 / A RUN TAKES SHAPE

A question becomes a sequence of decisions. Keep the path, not just the answer.

THE PRODUCT IS TAKING SHAPE

Project pages are an interactive preview. Local artifact checks are available; accounts and private run repositories use this installation’s configured services. Code mirrors are still being built.

EVIDENCE BESIDE THE FORGE

Code has a home.
Give its history one, too.

Your code stays at GitHub, GitLab, Forgejo, or your chosen upstream. An OpenTine project will pair its read-only mirror with the agent runs that belong beside it.

Files and commits on one side. Decisions and run evidence on the other. One place to understand the relationship.

YOUR UPSTREAM

The code you already own.

  • Files and README
  • Branches and commit history
  • A read-only view, with its source named

YOUR RUN REPOSITORY

The story behind the changes.

  • Recorded steps and branches
  • Portable run evidence
  • Browser artifact verification
Illustrative product model. No upstream code or run evidence has been loaded.

THE SERVER IS NOT TRUSTED

Keep the original.
Check it yourself.

The host can store and index evidence. It should never be the source of truth about that evidence. That is why OpenTine puts verification in the viewer’s browser and preserves independent, offline verification.
