Documents are edited by UER only — deliberately, so there is always one authoritative version.

Use the Feedback form above: pick the document, write your comment, attach one file if it helps (marked-up PDF, sketch, voice note — max 10 MB). Every submission is logged, lands instantly in the review inbox, and is answered — accepted, deferred, or rejected with the reason — in a consolidated comment-response log issued with the next revision.

Alternatively, reply to the cover email — that route stays open. If you drop files there, start each file name with your initials and the document number (for example FA_PRC-0008_isolation_valve.pdf).

Every comment is logged and answered — accepted, deferred, or rejected with the reason — in a consolidated comment-response log issued with the next revision.
