# Architecture

`core/device.ts` owns capability collection, the explicit probe registry and redaction. Passive checks use only synchronous API presence, media queries, display fields, `getSupportedConstraints` and `canPlayType`. Probe functions are separate and reachable only from individual UI actions.

Results retain human-readable local details in React state for the current page lifetime. Report creation builds a new allow-listed structure and buckets high-entropy values. It never serializes navigator objects, media devices, GPU adapters, streams or raw exceptions. Camera/microphone/screen functions stop every track before returning.

All Vite assets use relative paths for nested portal mounting. Release packaging fixes ZIP ordering, timestamps and permissions.
