APDS governance
Traceable data. Visible uncertainty.
AVRelated separates source claims, normalized values and editorial interpretation.
Source first
Important product claims identify the authoritative source that supports them.
Conditions preserved
Measurement conditions remain attached to values used in filtering and comparison.
Unknown is valid
Missing data is shown as unknown; it is never invented to make a record look complete.
Lifecycle tracked
New, current, legacy and discontinued states retain dates and evidence.
Corrections logged
Material changes retain the reason, source, reviewer and revision date.
Promotion separated
Manufacturer language and commercial relationships never masquerade as independent technical judgement.
