Case contract

codes "aisle-bay-level" with decimal parts and optional surrounding whitespace. Valid aisles 1-40, levels 1-6. Canonical form "AA-BB-L" (two-digit aisle and bay). Duplicates collapse. Sequence: aisles ascending; odd aisles walk bays ascending, even aisles descending; level ascending within a bay. Invalid codes are returned as given, sorted, duplicates kept. Return [sequence, invalid].

Why this case matters

Pick paths are sequenced from location codes in a serpentine walk.
