"""Phase 1 pipeline runner — executes all Phase 1 scripts in sequence.

This script runs the complete Phase 1 pipeline:
  1. Electrochemical stability windows (Li/Na entries)
  2. CAVD channel dimensionality (all Li/Na entries with structures)
  3. SSE candidate score (all entries, 5-gate system)
  4. Mechanical properties (all entries, geometric proxy)
  5. Oxidation states (all entries, BVA + heuristic)
  6. JARVIS EaH (internal convex hull)
  7. Commercial-safe edition extraction
  8. Garnet enrichment (structure-based reclassification)

Usage:
    python scripts/run_phase1_pipeline.py                        # full pipeline
    python scripts/run_phase1_pipeline.py --steps 1,3,5          # specific steps only
    python scripts/run_phase1_pipeline.py --dry-run              # stats only, no writes
    python scripts/run_phase1_pipeline.py --skip-write           # compute but don't save
