RAW_BUFFERClick to expand / collapse

What happened?

Interactive Ctrl+C is usually handled by the UI and can route to /quit on the second press. But raw SIGINT, SIGTERM, and SIGHUP are also registered. That path runs runExitCleanup() and exits. It does not validate whether the current session file is complete or resumable. It does not flush any higher-level recording state beyond already-synchronous writes. If the process is interrupted around initialization or recording failure, the session can be left incomplete.

packages/cli/src/utils/cleanup.ts:135

async function gracefulShutdown(_reason: string) {
   if (isShuttingDown) {
     return;
   }
   isShuttingDown = true;

   await runExitCleanup();
   process.exit(ExitCodes.SUCCESS);
 }

packages/cli/src/utils/cleanup.ts:145

  process.on('SIGHUP', () => gracefulShutdown('SIGHUP'));
  process.on('SIGTERM', () => gracefulShutdown('SIGTERM'));
  process.on('SIGINT', () => gracefulShutdown('SIGINT'));

What did you expect to happen?

Signal shutdown should perform a best-effort session integrity check. If the file is metadata-only, missing metadata, or recording was disabled, the CLI should not later imply that it was a healthy saved session. Any cleanup should avoid deleting very recent incomplete files. The shutdown path should preserve recoverability wherever possible.
