Fix-Finding Pipeline

Layer 1: Quick Fixes

Try OCR alternatives and character similarity swaps (R/K, a/g, 3/8, etc.) Auto-applies if exactly ONE fix is legal.

OCR autofix

Auto-applies the OCR alternative if exactly one is legal. Check moves flagged with ⟳ carefully — OCR may pick a legal but wrong move.

Similarity autofix

Auto-applies character similarity swaps (R/K, a/g, 3/8, etc.) if exactly one is legal.

Layer 2: Deep Search

Backtrack through earlier moves to find fixes. Results shown for confirmation.

Search depth:

Phase 1 searches from frontier to stuck move. Phase 2 extends backward.
