Vendor Claims Drift (monthly)

Monthly evidence counts from selected software claim checks, wording monitoring, reviewed Price Watch captures and exit tests. We pair vendor wording and its reading date with an observation on the named plan and test date. The unit is a recorded claim check, not a vendor; several checks may concern one tool. Contradicted means the claim and observation describe a comparable quantity but differ in this test; buyer direction is recorded separately. Not comparable and not testable are not contradictions. Wording events mean the original wording was absent after a successful source read; they do not establish intent. Failed reads are not changes. The watch event ledger counts detections, not necessarily unique claims. Price Watch uses paired monthly captures and human-reviewed changes, including restructuring and withdrawals. Dates mark observations or detection, not the exact time a vendor edited a page. We do not measure announcements, intent, all features, all plans, paid production use or the software market. Selection reflects our tool catalogue and available trials/free accounts; these tests use small synthetic datasets. Exit loss refers only to the tested route and records, not complete portability; without file inspection it is unknown. No percentages are reported, including for groups with n below 20. These results cannot be extrapolated to the market.
