| 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. | An account is required and community, publisher, designer, shop, yarn, project, and connected-app records can vary in currency and accuracy. The checked public pages do not establish API credential eligibility, current endpoints, scopes, rate limits, support, app quality, or a complete account export. Search results, ratings, favorites, and project examples do not establish pattern accuracy, yarn availability, seller reliability, fit, gauge, or project suitability. Confirm current developer terms, files, errata, license, purchase and refund terms, measurements, yarn details, and shop information with the responsible source. | A profile, match, uploaded credential, training credit, award, or platform ranking is not independent certification of a supplier or proof of current capability, performance, impact, capacity, or project fit. The platform's own ranking inputs and paid visibility affect discovery. Verify credentials with the issuer and check the legal entity, production site, claims, samples, references, terms, and compliance directly. | The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. |

| Free-account boundary | Not yet reviewed at this level. | A free account requires a valid email signup link and enables the database, notebook, directories, groups, and forums. The public Goodies page sends developers to an account-gated API group; it does not establish current credential eligibility, scopes, endpoints, rate limits, or support. | A free account provides a personal or business profile, limited monthly connections, free content, and up to three portfolio items. | Not yet reviewed at this level. |
| Payment boundary | Not yet reviewed at this level. | The core platform account is free. Individual patterns and other marketplace items may have separate provider-set prices; those purchases are not a user subscription. | PRO adds unlimited connections, paid content and training, more profile capacity, and business sourcing workflows. Monthly and annual routes use provider-set terms. | Not yet reviewed at this level. |
| Cancellation or exit | Not yet reviewed at this level. | The checked public about, login, and signup pages do not establish cancellation, deletion, or post-exit access.

| Saved work and data | Not yet reviewed at this level. | The Goodies page documents a stash spreadsheet and a Project Progress API JSON route, but it says exports are limited and does not establish one complete account export. Keep source files and critical records locally. | Profiles can contain files, work history, product galleries, and sustainability evidence. The current access and pricing pages do not establish full export or deletion; retain originals. | Not yet reviewed at this level. |

| 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. | Ravelry's official description identifies a user-driven database of knitting and crochet patterns and yarns, searchable directories, and a personal notebook. Community members and volunteer editors maintain database records. The current official Goodies page exposes an account-gated developer API route, a limited Project Progress API JSON export, and a stash spreadsheet; the official apps directory lists third-party apps that connect to Ravelry. | Common Objective currently offers free individual and business profiles, personalised matches, supplier and content search, and limited monthly connection requests. Paid tiers unlock unlimited connections, additional content, training credits, and the CO Create sourcing workflow. Businesses enter their own profile information and upload certification or membership evidence; profile completeness, sustainability material, training credits, awards, and paid capabilities can influence visibility or ranking. | The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. |
