It defines all ten evidence labels and what each does not mean, names the six dates a fact can carry, says what a profile shows when a connector disconnects, a source disappears or two sources disagree, and states what a profile does not establish. An invented example company can be inspected without an account; selecting a fact shows its source, label, dates and processing. Two sentences the earlier page carried were wrong and are gone: it said the outcome of every settled dispute is shown on a company's Trust Profile, which stopped being true on September 26, and it said every reading is signed, while the profile's facts and a company's declarations are not signed. ## Why it changed The earlier page could not be cited: it had no version, no effective date and no owner, and two of its sentences described the product wrongly. ## Who is affected - **Affected:** Anyone reading a Trust Profile, citing Trooth's methodology, or deciding whether to rely on a profile. Nobody's integration is affected. - **Availability:** Public. No account needed. - **Release stage:** Available. - **Areas:** Methodology, Trust Profiles. ## What to do **No action required.** No field, endpoint, label value or profile changed. Checked against the change itself: it touched the methodology page and its metadata only. **What comes next:** A material change will move the version and be listed here and on the methodology page before it takes effect. ## Versions and migration - **Methodology:** `1.0` ## Profiles **Published profiles were not reprocessed.** No profile was reprocessed. Version 1.0 writes down how profiles were already produced; it does not change how any fact is labeled. ## Dates - **Announced:** September 27, 2026, the day this entry was written. Entries are never backdated. - **Effective:** September 27, 2026. - **Released:** September 27, 2026. - **Methodology version 1.0 effective:** September 27, 2026. ## What this does not fix The correction policy names five outcomes for a settled challenge and the product records four, with different meanings for withdrawn; until one is changed to match the other, the methodology names neither list. The page has not yet been tested with readers from each audience it is written for. ## Corrections and later changes - **Corrected September 27, 2026:** Two sentences on the earlier methodology page were removed as wrong: that settled disputes are shown on a Trust Profile, and that every reading is signed. ## Read more - [Methodology](https://trooth.co/methodology) - [Publication, Correction and Right-of-Reply Policy](https://trooth.co/corrections) On this page - What changed - Why it changed - Who is affected - What to do - Versions and migration - Profiles - Dates - What this does not fix - Corrections and later changes - Read more [Methodology](https://trooth.co/changelog?type=methodology)[Improvement](https://trooth.co/changelog?type=improvement)[Fix](https://trooth.co/changelog?type=fix)[Methodology](https://trooth.co/changelog?area=methodology)[Trust Profiles](https://trooth.co/changelog?area=trust-profile) [Back to changelog](https://trooth.co/changelog) ## Related changes - [SEP.26NewA bill of materials for every Worker, and Trooth's own record correctedPlatform +1](https://trooth.co/changelog/2026-09-26-worker-bills-of-materials) - [SEP.26ImprovementCounts on a profile now come from the signed witness statementTrust Profiles +2](https://trooth.co/changelog/2026-09-26-counts-from-signed-statement) - [SEP.26ImprovementDisputes are handled privately; framework rollups and the old badge are retiredTrust Profiles +4](https://trooth.co/changelog/2026-09-26-disputes-private-rollups-retired) - [SEP.04DeprecationThe 0-100 figure is deletedTrust Profiles +3](https://trooth.co/changelog/2026-09-04-single-figure-deleted) - [JUL.24NewAPI keys, live outside-in reads, dispute path, /verifyAPI +2](https://trooth.co/changelog/2026-07-24-api-keys-live-reads) - [JUL.23NewTrooth Network on real directory dataNetwork +1](https://trooth.co/changelog/2026-07-23-network-on-directory-data) ## Follow what changes at Trooth Every entry by email, or a feed narrowed to one area or to the changes that need you to act. ## Product updates by email Occasional notes when something on this page changes.
