+"""Extract curated example blocks from a winning variant artifact (rubric v15, gate 8).
+
+Gate 8 (winner == B) requires, each matching the artifact JSON:
+  - >=2 deep-dive examples with 2 opposing roles on the same company
+  - >=1 screen example
+  - >=1 bullish-to-bearish flip
+  - >=1 neutral-to-bearish flip
+  - >=1 move toward bullish
+  - >=1 confidence tie-break
+
+Each example shows: fundamentals, initial view, peer evidence (where applicable),
+final view, reason. Categories with fewer than the required count print the best
+available and an honest shortfall note — nothing is fabricated.

+Runnable:  python scripts/extract_examples.py --artifact <path> --output <path>
