Task outcomes are a transparent knobbed model grounded in published anchors (Agent Forest saturation ~4; imperfect-verifier K<=5 inversion; MAST step-repetition 15.7%; naive MAS ~33-59% correct) and the real injection quarantine evidence in docs/benchmarks/LIVE-RESULTS.md. Cost columns are joined verbatim from the MEASURED fanbench artifact experiments/fanout/fanbench-research.csv. This lane proves the cost/quality SEPARATION; it does not prove real-model quality.",
