The Multi-Layered Evaluation Framework as a sequential diagnostic cascade
that STOPS at the first failing layer. Layer 0 is a zero-shot hallucination
gate (NLI grounding, catches 60-70% of hallucinations at under 5% of
full-judge compute). Layer 1 is a context evaluator (binary sufficient/not).
Layer 2 is a cognitive fault isolator (KNOWLEDGE vs REASONING). Layer 3 is
the TIR-Judge (correctness times format times tool, MULTIPLICATIVE
so a well-formatted wrong answer scores 0). The cascade emits a diagnostic report that names the
failure mode, locates it by node, and prescribes an intervention. Use to
autopsy a failed agent execution and route the fix (retrieval / prompt /…
