One folded note a day. Nothing to solve, nothing to get right, and no reason to hurry back.
These were written for this jar. Nowhere else in the cabinet does that — everything else here that states something is sourced, checked and linked, and inventing the content would be the whole problem. This drawer is the one exception, and deliberately so: a reassurance is not a fact, it has no source to cite, and a quotation lifted off the internet and misattributed would be exactly the failure the rest of the cabinet is built to avoid. So none of these is attributed to anybody, because nobody else said them.
One a day, decided by the date. Everyone opening the jar on the same day gets the same note, and it changes at your own midnight rather than somebody else's. The jar does not run out — it comes round again eventually, and a note you have had before is not a fault.
What you have already unfolded is kept in this browser and nowhere else. There is no account, nothing is sent anywhere, and clearing your browser data is the only thing that empties it.
