Its target changed before the verdict was used.
Owner, identity and version matter more than branch color.

Full written post / accessibility read
Imagine two tidy branches leaving two agent worktrees. They never edit the same file. Both point at one bright red staging tenant. One worker changes a permission fixture while the other captures a green screenshot. No merge conflict warns either one.
The screenshot and test log are authentic for the moment they ran. They are not proof about the resource after another worker changed it. That is why the visual shows both branch SHAs and one changing tenant version at the bottom.
For a disposable environment, give each worker its own tenant when possible. When sharing is necessary, use a lease and record version before and after the acceptance probe. The WAL should name the external target and its owner, not merely say test passed.
Show file isolation and external-resource isolation as separate boxes in the workflow. Refuse a green verdict when the target version no longer matches its evidence. This avoids asking the next agent to trust a correct test of a world that has already moved.

Four-beat scene transcript
1. Two clean branches. One red tenant.
Imagine two tidy branches leaving two agent worktrees. They never edit the same file. Both point at one bright red staging tenant. One worker changes a permission fixture while the other captures a green screenshot. No merge conflict warns either one.
Visual: File separation does not separate the customer effect.
2. The test can be right and stale.
The screenshot and test log are authentic for the moment they ran. They are not proof about the resource after another worker changed it. That is why the visual shows both branch SHAs and one changing tenant version at the bottom.
Visual: Its target changed before the verdict was used.
3. Put a label on the resource.
For a disposable environment, give each worker its own tenant when possible. When sharing is necessary, use a lease and record version before and after the acceptance probe. The WAL should name the external target and its owner, not merely say test passed.
Visual: Owner, identity and version matter more than branch color.
4. Track what the branches touch.
Show file isolation and external-resource isolation as separate boxes in the workflow. Refuse a green verdict when the target version no longer matches its evidence. This avoids asking the next agent to trust a correct test of a world that has already moved.
Visual: Re-run evidence when shared state changes.
