The 2026 development
Google announced Chrome auto browse for bounded tasks such as appointments and parking reservations.
The governance gap
An errand may spend money, accept terms or create a booking. The agent needs a bounded task, a payment ceiling and a clear stop before it commits.
Where CAIN-42 fits: Moat 5 — Predictive Trust & Blast Radius
Core question: What could happen before we let it happen? Pre-execution analysis of reach, exposure and consequence, including simulations.
Declare the errand's bounds before browsing: sites, spend, time and acceptable commitments. The firewall refuses a checkout or a terms acceptance outside the declaration.
How the wiring works
- Declare allowed sites, spend ceiling and commitment types.
- Score each action against the declaration.
- Pause before payment or binding terms.
- Record the confirmation and the receipt.
What is real today
LIVE A public route in this deployment exercises this mechanism today, within its stated scope.
The browser firewall demo evaluates fixed presets. It does not drive Chrome or book anything.
