A surveillance surface grows when a system collects detailed information across time and makes it searchable, linkable, or available to automated inference. Personal context can reveal more when combined than individual records reveal separately.
The surface is shaped by retention, access, integrations, logging, model capabilities, and secondary uses. Limiting collection, separating purposes, enforcing access, auditing queries, and providing deletion controls can reduce exposure while preserving bounded personalization.

A surveillance surface is the information and access that could be used to watch or build a detailed profile of someone. It becomes larger as more personal records are collected and connected over time.
For example, an assistant that stores messages, locations, contacts, purchases, and health questions could reveal a great deal about a user if all of that context is searched together. Strong limits should control collection, access, retention, and reuse.
