Debugging guide should add a hard gate before declaring root cause

[wtmoose]

Friction

Agents repeatedly declare a root cause and apply fixes without sufficient discriminating evidence or human approval. The current guide mentions getting human approval but doesn't make it a prominent hard gate, leading to the most common failure mode in LLM-assisted debugging: premature root cause declaration followed by speculative fixes.

Suggestion

Add a prominent stop-gate to the debugging guide: "STOP GATE: Before declaring a root cause, you MUST have discriminating evidence that rules out alternative explanations. Before applying a fix, you MUST present the root cause and proposed fix to the human and get explicit approval. Violations of this gate are the #1 failure mode in LLM-assisted debugging."
