Two analytics corrections verified against the production capture:
- pagerite.js suppressed pings with fr == '/_a', but fetch-navigation
away from the analytics page had already GET-ed the target without the
preload header; the orphaned pending hit then flushed to the crawler
list, classifying a real user as a crawler. Navigations away from /_a
now ping normally (the server rejects /_a as a target regardless, and
admin noise is already handled by hide=1).
- _remove_visit only reversed the visit's creation counts, leaving
views/transitions from later pings behind as orphans on the graph with
no matching row in the visitor table. An in-memory per-visit count log
now tracks every count event, so an admin hide=1 scrub reverses the
visit completely.
