Model-Guided Escalation & Synthesis Role
When-not-to-use failure boundary summarizer
5-Role Component Pod: 0-Call Slot / Solver + OpenSearch / Split-Supervisor (≤4k tok) / Diagnostic Repair + Twin Shim / CPOP + Sister Distiller.
Enforced Category State Machine: rux_harness_benchmark_audit
Commit Invariant: Enforces identical tool/prompt scaffold parity across models on uncontaminated holdouts and flags scaffold inflation whenever retry budgets or custom wrappers diverge.
Architectural Problem Solved: Separates genuine model or substrate lift from benchmark-specific scaffold gaming.
