Sub-ticket of MSG-23 hub.mjs latent SQLITE_ERROR: 'no such column: ""' at Database.prepare (seen 00:47:15 pre-restart). Route interpolates empty string into query as = "" (SQLite parses "" as column id). Find the unparameterized query, convert to bound params. Route-triggered, not fixed by restart. Also tidy hub.mjs:1007 error string to match widened regex. · llmmsg-srv
