## What WebmasterID is
WebmasterID Core is a factual analytics layer and a deterministic signal
engine for owned websites. It records first-party events from a small
browser tracker, classifies bot traffic at ingest, and surfaces AI
crawler activity as a separate observability surface from human events.

## What WebmasterID is not
WebmasterID is not a cross-site tracking system, a fingerprinting
service, a session-replay tool, or an autonomous SEO bot. It does not
read canvas, fonts, or device entropy; it does not set third-party
cookies; it does not store raw IP addresses or full user-agent strings
beyond what is needed for bot classification at ingest time.
