It was the kind of error message that made systems administrators break out in a cold sweat. On a humid Tuesday night in late October, the main server cluster at NexusTech Solutions began to fail. Not with a bang, but with a persistent, pulsing yellow light on the primary node and a single line of text on the console: Dual Core Scheduler Mismatch. Kernel Panic Imminent.

She didn't have credentials, but the old forum post (#39) had contained a hint: "The key is in the L2 cache." Back then, it was a joke. Now, she realized it was literal.
