Tap the version seven times and the app now has a developer tab: startup timings, every request it makes, how stale each cache is, and how many frames it dropped. The interesting part was not building it, it was working out what it is allowed to say, because this thing is holding somebody’s Neptun password. So the list of stored keys is an allowlist rather than a blocklist, meaning a key I add next year is hidden until I say otherwise, and the cached grades and messages only ever show their size. The redaction lives in the recorder instead of the screen, which matters more than it sounds, because one of my own URLs turned out to be a credential and a log that printed URLs would have published it.
