The goal is simple: keep the compare surface useful without faking certainty. We would rather show a blank, a baseline label, or a follow-up note than silently guess a spec and make the page look complete when it is not.
A blank field usually means we have not verified that spec yet, not that the mower lacks that capability.
This is deliberate. Leaving gaps visible makes it easier to prioritize follow-up work and prevents fake precision from slipping into the compare surface.
When a source is added or reviewed later, the model row and its review history update together.
Not all sources carry the same weight, so each one is labeled accordingly.
Manufacturer pages, manuals, and support documents are the primary baseline whenever they exist.
Retailers, reviews, and trusted third-party listings help fill gaps, but they do not override better primary documentation.
Reddit and community roundups can seed coverage early, but they stay clearly labeled until a better source confirms them.
The source exists in the system, but nobody has confirmed it manually yet.
A person has checked the live source and added reviewer metadata or notes.
The source was checked, but the claim still needs more verification or clarification.
Seed the model with a source-backed baseline row.
Attach source records for the claims we currently know.
Mark review state explicitly instead of pretending every field is verified.
Leave blanks in place until a stronger source fills them.
