Find the cause of network failures with evidence.
Investigates network failures through falsifiable experiments and delivers a documented diagnosis with fix verification.
When to use it
Use for network, streaming, or protocol symptoms when the cause is uncertain and a diagnosis risks resting on one circumstantial observation.
Give it a reported network problem; it investigates and returns an incident report covering evidence, rejected hypotheses, the decisive experiment, and fix verification.
Python 3 runs the bundled mock upstream when a controlled SSE idle-timeout experiment is needed.
Flask is required when using the bundled mock upstream; the script exits if it is unavailable.
