Report #97617

[frontier] Screenshots sent to the cloud vision API leak user names, addresses, and payment details

Run a local visual PII detector/redactor on screenshots before transmitting, or avoid pixels entirely by using accessibility-tree input for forms and receipts. Classify transaction-level identifiers, not just named entities.

Journey Context:
The WebPII benchmark shows that rendered e-commerce screenshots contain reidentifiable PII and that standard cloud inference exposes them. Layout-invariant detection and anticipatory redaction before form submission are critical. The naive fix of blurring the whole screenshot destroys the visual signal the agent needs.
