| Know before using | The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. | The record does not reproduce licensed code diagrams, verify a user's proposed code, authorize an ISO and ASTM crosswalk, select a construction, set stitch density or machine settings, prove supplier repeatability or performance, or replace the licensed standards and qualified construction, sewing, production, testing, safety, and quality review. | A foundational library, not yet an exhaustive stitch encyclopedia. |

| What the source establishes | Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. | The guide cites the official DLA cancellation record for FED-STD-751A and the current public scopes and statuses of ISO 4915:1991, ISO 4916:1991, and ASTM D6193-16(2025). It records ISO 4915's July 2026 systematic review and keeps classification, ambiguous-code recovery, translation, complete process definition, physical verification, and performance evidence separate. | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. |
