Culprit Finds the Bottleneck Hiding Across the Stack

Why it surfaced

Instead of another dashboard, Culprit applies ten deterministic rules to CPU, memory, disk I/O, networking, browser JavaScript, databases, and downstream APIs. Its single static server binary and shared-session model give the tool a clear operational point of view: reproduce the slowdown once, then get evidence for what actually caused it.

Culprit correlates browser and server telemetry from the same test run, then produces a ranked performance diagnosis.
