Uses a simple heuristic: if a value has a next sibling in the parsed structure, it must be complete. For the last sibling, we don't know until the parent completes - but that's fine because parent validation will cover it. Example: tracker = JsonCompleteness() # Incomplete - missing closing brace tracker.analyze('{"name": "Alice", "address": {"city": "NY') tracker.is_path_complete("") # False - root incomplete tracker.is_path_complete("name") # True - has next sibling "address" tracker.is_path_complete("address") # False - last sibling, unknown # Complete tracker.analyze('{"name": "Alice"}') tracker.is_path_complete("") # True - root complete c"t|_y)N)set_complete_pathsselfs r __init__zJsonCompleteness.__init__6s ),c<t|_|r|jsy t|j }|j |dy#t $rYnwxYw t|j d}n#t $rYywxYw|j|dy)z>Analyze a JSON string and determine completeness of each path.Nztrailing-strings) partial_mode)rrrrr _mark_allr _check_siblings)rr parseds r analyzezJsonCompleteness.analyze9s"ux~~/  x01F NN62 &     x0?QRF    VR(s#+A AA A<< BBc>|jj|t|tr6|j D]"\}}|r|d|n|}|j ||$yt|t r,t|D]\}}|j ||d|dyy)z3Recursively mark path and all children as complete..[]N)radd isinstancedictitemsrlist enumerate)rdatapathkeyvalue child_pathiitems r rzJsonCompleteness._mark_allPs   & dD !"jjl 2 U04vQse_# uj1 2d #$T? 54tvQqc^4 5$rct|trtt|j}t |D]L\}}|r|d|n|}|t |dz kr|j |||8|j|||Nyt|trRt |D]C\}}|d|d}|t |dz kr|j ||2|j||Eyy)z Check completeness using sibling heuristic.
