ShotUn.Trace.Node (shot_un v0.1.9)

Copy Markdown View Source

A single node in a ShotUn.Trace decision tree.

Each node represents the state reached after applying rule to its parent's state. The root has kind: :start, rule: :init and no parent; leaves are either :solution or :fail. All term-bearing fields are pre-formatted strings captured while the term-factory scratchpad was alive, so the tree remains meaningful after the algorithm tears down its scratchpad.
