Result
The simulation yields 64 non-uncertain results out of 72 and 8 uncertain states. It avoids false favourable outcomes, but retains three false negatives and turns disagreements into abstentions.
Simulated pipeline coverage
Simulation over 72 historical corpus cells; not a production result.
Trade-off
Average simulated cost is below Sonnet alone because verification is conditional. However, the P90 workflow reserve can be higher and pedagogical signal worsened.
What remains useful
Disagreement carries information: it signals a case where LearnX should abstain. But models should no longer be the authority assigning final levels.
