The protection was real but rested entirely on how the connection is assembled, so a future change to that assembly could have opened writing with no test noticing. Any write added later inherits the check. +- **Names and text read out of your records now carry an explicit boundary when handed to a connected assistant**, matching what the app already does for its own assistant. +- **Reading a medication list from a photo measured its cost against the server-wide limit even when you use your own key.** It now uses your own limit. The older way of counting that caused this — the third surface to have it — is removed entirely rather than fixed in place, so nothing can reach for it again. +- Removed a module that read as a check on generated recommendations but had not run for some time. It could not simply be switched on: it required fields the current format does not have, so enabling it would have rejected nearly every generation.
