Board symmetry transformations are incorrect and markDuplicateMoveLocs misidentifies symmetric duplicates
Board symmetry transformations are incorrect and markDuplicateMoveLocs misidentifies symmetric duplicates: a task in LegoFlow-SWE (Harbor dataset). Observed symptom Applying a symmetry operation to a board position and then applying its inverse symmetry does not always return the original…
The task
**Observed symptom** Applying a symmetry operation to a board position and then applying its inverse symmetry does *not* always return the original location. This round‑trip failure occurs for several of the 8 supported symmetries (indices 0–7). As a consequence, `markDuplicateMoveLocs` produces an incorrect…
