How Watchdog handles data
Every marker belongs to a source, refresh rule and access tier. Proprietary Watchdog markers remain explainable: the original public facts stay distinguishable from the calculation built on top of them.
Authoritative sources
Core sources include the New Jersey Division of Taxation, Department of Community Affairs, Department of Environmental Protection, county/municipal property records and other identified public agencies. Marker detail pages identify the relevant source family and known limitations.
Refresh policy
Annual, quarterly, monthly and live-query datasets are tracked separately. Publication by the authoritative agency always takes precedence over an estimated calendar. Watchdog monitors supported official endpoints for publisher changes and routes changes through validation before new data becomes production input.
Derived markers
A derived marker combines public or previously governed inputs into a new decision signal. Formula versions, input lineage, scope, plan tier and professional fit are recorded in the marker registry/formula system. Missing evidence should reduce confidence or neutralize an input rather than be silently interpreted as favorable evidence.
Corrections and provenance
Government corrections can change historical results. Watchdog keeps release history and source-freshness records so a professional can understand when inputs changed. The authoritative agency record controls whenever Watchdog conflicts with it.
Privacy and Daniel's Law
Watchdog does not rebuild owner-name data that has been removed from the public distribution. Property intelligence is organized around the parcel and jurisdiction, not a hidden personal-data dossier.
