METHOD / EVIDENCE FIREWALL
A directory that shows its work.
Every listing is an observation recorded on a date and linked to a vendor or PMS source. We do not assign ratings, user scores, or invented capacity figures.
Checked means the site, pricing path, PMS evidence, and portfolio guidance were reviewed.
Platform-bound means the product requires a named PMS. Not stated means the source did not publish the fact.
Source hierarchy: official vendor product and integration pages first; official PMS marketplaces and association exhibitor pages second; other sources are not used to confirm compatibility.
Integration claims are scheduled for monthly review; a record should be treated as stale when its latest observation is older than 31 days.
Sponsored placement is labeled and cannot change a verification state or move ahead of a verified organic result.
Security, privacy, and compliance statements are quoted as vendor claims with a source date. PropAtlas does not turn them into an independent certification.
