For captures like "Kxg4" vs "hxg4"
Searches OCR alternatives and character similarity swaps (R/K, a/g, 3/8, etc.) and surfaces matching legal fixes as clickable suggestions. The toggles below opt specific categories into auto-applying when exactly one fix is legal.
Backtrack through earlier moves to find fixes. Results shown for confirmation.
Phase 1 searches from frontier to stuck move. Phase 2 extends backward.
A move whose top OCR confidence falls below this is flagged for a mandatory review stop (🔍), even when it's a legal move. Tradeoff: lower it and more uncertain moves play straight through — faster now, but a wrong-but-legal read can bite you many moves later. Raise it to catch more errors up front, at the cost of reviewing many more moves.
Launch these searches automatically when entering interactive mode. In batch mode they also gate auto-escalation: a disabled method is never queued (Greedy always runs as the base).
