Pilot sweep (all 4 gates, small_plus + medium): verification_type 84.3% (medium, no_gain_stop_scaling) worker_type 80.8% (small_plus, scale_more) automatability 78.3% (medium, decompose_or_relabel) prereq_op 72.2% (small_plus, decompose_or_relabel) Automatability: 2-stage decomposition resolves Directional Collapse. Stage 1 binary (low_entropy vs needs_routing): 100% Stage 2 4-way (specialist/slm/llm/human): 100% Combined 5-way pipeline: 100% Script: specialists/scripts/split_automatability_decompose.py Worker_type: combined dataset (sprint plans + projects) improves implementer class from 42.9% → 75.0%, overall 80.8% → 92.2%. Combined train/eval TSVs added. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
