The client (public/app.js's submitNumber) only accepts whole numbers matching /^\\d+$/ that pass Number.isSafeInteger, so zero or positive integers up to Number.MAX_SAFE_INTEGER — there is no declared upper bound beyond that. One record per distinct value; the client dedupes client-side against listRecords before writing, but nothing server-side stops duplicates or negative/fractional values from being written directly. Written by an authenticated user to their own repo; read unauthenticated (com.atproto.repo.listRecords) both for the signed-in user's own board and for anyone else's public board view. Written and read by numbergrid (https://numbergrid.bisks.net).",
