Field note
Four investigators, three corrections
Separate methods and permission to falsify prior conclusions mattered more than the number of investigators.

How the claim changed
Belief
Using several agents to investigate the same bug should reduce the chance of a shared mistaken diagnosis.
Evidence
A Codex-LB shutdown race was investigated by a code-reading worker and an empirical worker.
Contradiction
A verifier using a different method overturned parts of the earlier diagnosis. Orchestrator remeasurement then found another risk outside the verifier’s coverage.
Correction
Define independence by provenance and method, and explicitly allow each investigation to falsify earlier conclusions.
Current claim boundary
Multiple agents are not automatically multiple independent pieces of evidence.
