- Rewrote CORRECTIVE_PROMPT_TEMPLATE to clearly distinguish option→child
vs action→sibling next_node_id semantics with concrete examples
- Added global check in ai_tree_validator that action next_node_ids
actually reference existing nodes in the tree (was silently unchecked)
- Added max_tokens truncation warning to branch_detail logger
- Added test for action next_node_id referencing nonexistent node
