The trust problem moved from replay to resume.
Session replay shows what happened. Browser caches remember what the agent saw. Neither is enough when an agent pauses, returns later, and acts on a changing web page.
Verifiable resume trails are becoming the control layer.
A resume trail ties together cached evidence, fresh browser state, user approval, and the final route. It makes delayed autonomy inspectable before the click happens.
- It records the old page state and the refreshed state.
- It marks which changes are harmless and which need approval.
- It shows whether the active account and target page are still correct.
Caches need proof
Cached context is valuable, but a browser agent needs proof before reusing it for action.
Approvals need scope
A user approval should expire when the account, price, recipient, or destination changes.
Logs need timing
A post-action audit log is useful, but it does not protect the resume decision itself.
Where Super fits
Super-style workflows can surface resume trails across computer-use cache, text message AI assistant approvals, and AI agent website building.
