+//! upstream of that gap is the only durable reason for a paid feed to exist:
+//! not "we have the same list as everyone else", but "we saw it first".

+//! The raw material is entirely public. npm publishes a CouchDB `_changes`

+//! here needs a single byte of user data — which is the answer to how a
+//! product with no telemetry grows its detection.

+//! each package to the detectors Hound already has. The analysis is the same
+//! code that runs on a developer's laptop. That matters twice over — it is
+//! less to maintain, and a rule that fires here fires there identically.
