Submit a published form (no auth — by public token)

POST 
/api/forms/public/:token/submit

Submit a published form. The body may be a {values:{…}} envelope or a flat field map, plus the optional __url and __utm context.

Doc 90: r (personal link token) binds the answers to its contact and is single-use; a SIGNED form needs __version (the version shown, 409 version_changed otherwise) and signing: \{name, signature (data URL JPEG/PNG), clauses: \{key: true\}\}.

Keys that are not one of the form's fields are DROPPED, not stored — only defined fields are validated, so an undefined key was never checked. The consent field named in the form's settings is the one exception and is always accepted.

Bounded: the body may not exceed 64 KB or 100 fields (413 / 422), and the endpoint is rate-limited per form token as well as per client IP.
