Oracle Gap And Signal Fidelity A Fixed Pool Diagno

# Oracle Gap and Signal Fidelity: A Fixed-Pool Diagnostic for Test-Time Collaboration

Derived from arXiv:2607.17531 - Oracle Gap and Signal Fidelity: A Fixed-Pool Diagnostic for Test-Time Collaboration

## Core Concept
Test-time collaboration, including self-consistency, best-of-N selection, critic models, and verifier pipelines, is often credited with broadly improving LLM reasoning, yet its gains are uneven and sometimes negative. We ask when training-free collaboration should be expected to help. For a fixed candidate pool, we decompose a selector or verifier's net gain into measurable factors: recoverable mass, verification-signal coverage, conditional selection quality, and harm to already-correct outputs...
