Bug Description

server.js has no process.on(unhandledRejection) or process.on(uncaughtException) handlers. Combined with the async routes lacking try/catch (see #68), any unhandled promise rejection from Express 4 async handlers will crash the process with no structured error reporting.

The only process exit points are in the main() catch block for startup failures.

Affected Files

server.js (missing)

Impact

Silent process crashes in production with no structured logging. Difficult to diagnose recurring crashes.

Recommended Fix

Add:
process.on(unhandledRejection, (reason, promise) => { logger/error tracking });
process.on(uncaughtException, (err) => { logger/error tracking; graceful shutdown });
