A reminder for returning to the whole task

Keep the required result and its conditions in view; when the way is unsettled, compare complete available ways, including setup, checking and use, and choose on the evidence and preferences that matter; inquire only when the answer can change that choice enough to justify its burden; perform the selected self, supported or mixed operation and use its result in the whole; distinguish missing knowledge, access, timely observation and ability to act; for a recurring difficulty, compare changed support, changed execution and developed capability; test the chosen change now, after the relevant interval and under changed conditions; retain necessary observations and checks; stop at a usable result or return the exact missing condition.

Use this reminder to resume the explanation, then open the question that matters. It recalls the dependencies worked below; it neither supplies missing evidence nor makes every branch compulsory. The procedure-availability description, current-continuation description and development description answer narrower formal questions after the connected cases.
