// Step 1879 TDD: GR-010 — SemanticCompletionGate enforces meaningful semantic threshold
//
// ImprovementPromotionGate had a threshold of 0.02 (nearly anything passes) and no
// depth tracking. SemanticCompletionGate requires score >= 0.70 and depth <= 5.
//
//  t1: score=0.95, depth=0, humanApproved=false → passed (score >= 0.90 auto-pass)
//  t2: score=0.75, depth=0, humanApproved=true → passed (human approved)
//  t3: score=0.50, depth=0, humanApproved=false → NOT passed (below threshold)
//  t4: score=0.95, depth=6 → NOT passed (depth exceeded)
//  t5: score=0.75, depth=3, humanApproved=false → NOT passed (needs human approval)
