The phone reported every build as current because the release repository is private. Gitea answers 404 rather than 403 for a repo you cannot see, the client reads that address anonymously, and AndroidUpdateChannel caught the failure and returned null — which IUpdateChannel documented as meaning "this build is the latest". The check had never once succeeded on any phone and nothing anywhere said so. Two faults, and the second is why the first lasted. The seam said null was the honest answer for an unreachable channel, on the reasoning that the caller does the same thing either way. That is true of the six-hourly pass and false of CHECK NOW. UpdateViewModel already draws the line correctly — silent on the timer, the exception's message on the button — and it could only ever draw the first half, because nothing was ever thrown at it. The desktop's channel does not catch, so the interface described neither implementation. So CheckAsync throws now, and null means one thing. A release that is reachable but missing its manifest or the APK it names throws too: "you are up to date" about a half-published feed is the same lie in a smaller costume, and the self-healing that argument protected is untouched, since the timer still swallows everything. The precondition is written down where somebody would look, rather than left as a sentence about where a token could live. ADR 0013 §4 already said a private release repository was incompatible with this design; nobody checked which side of it this repository was on. It is one curl, and manual-checks phase 16 now opens with it — pointedly not against /api/v1/version, which answers 200 from a forge that is up whatever is readable on it, and which is what made this look like nothing was wrong. Phone check 17.4 was the one that passed all along. It now presses CHECK NOW with the network off as well as on, because two different answers are the whole of what makes the first one worth reading.
