Found in the alpha load test: client-chosen pairing codes collide by birthday paradox, the provisioning INSERT hit UNIQUE(devices.pairing_code), the SqliteError threw out of the (synchronous) socket handler -> uncaughtException -> logFatalAndExit -> the WHOLE server exited and every device dropped. The colliding flood crash-LOOPED the container (2 restarts). Two layers, same "one device can't take down the fleet" theme as #142/#143/#144: 1. Narrow (deviceSocket.js): wrap the device:register provisioning INSERT in try/catch — a UNIQUE pairing_code collision (or ANY db error) rejects THAT registration (device:auth-error -> client retries) instead of throwing. currentDeviceId/authenticated now set only AFTER the row exists (no half-auth socket on failure). 2. Broader (lib/safe-socket.js): protectSocket() overrides socket.on per connection so any handler throw is caught, logged (event + id + stack), the socket told, and DISCONNECTED — per-CONNECTION fail-fast, not whole-PROCESS. We don't keep serving a connection from possibly-half-mutated state (honors the existing fail-fast intent), we just contain it to "one device reconnects" (a non-event after beta5). Wired into both the /device and /dashboard connection handlers; auto-covers future handlers. Audited first: no handler throws as control flow, so blanket-wrapping is safe. Tests (mutation-verified, fail without their fix): - register-insert-crash.test.js: a pairing_code collision AND a general bind error each reject-one-device with no uncaughtException; server keeps serving. - socket-handler-isolation.test.js: a throwing handler disconnects only that socket; the server + other sockets stay alive.
