/reflect-tree-update — Tree Update Protocol

This sub-skill implements the shared Tree Update Protocol used by /reflect-on-outcome (Hypothesis mode) and /reflect-on-self (Patterns mode). It is invoked after any reflection that updates memory tree nodes, to propagate new insights upward through the tree hierarchy. After EVERY reflection, update the memory tree to propagate new insights upward.

Step 0: Load Conventions

Step 0: Load Conventions — Bash: load-conventions.sh with each name from the conventions: front matter. Read only the paths returned (files not yet in context). If output is empty, all conventions already loaded — proceed to next step.

Step 1: Identify Affected Node (Dynamic Lookup)

Use dynamic lookup to find the right node — never hardcode category->path:

node=$(bash core/scripts/tree-find-node.sh --text "{hypothesis.category}" --leaf-only --top 1)
# Returns: {key, score, file, depth, summary, node_type}
target_file = node.file

Also update performance nodes as needed:

• Pattern/violation discovery → bash core/scripts/tree-find-node.sh --text "pattern-extraction" --top 1
• Calibration insight → bash core/scripts/tree-find-node.sh --text "calibration-analysis" --top 1
• Accuracy change → bash core/scripts/tree-find-node.sh --text "hypothesis-accuracy" --top 1

Step 2: Update Target Node (Depth-Generic)

Behavior depends on whether the target node is a leaf or interior node:

If target is a LEAF node AND insight is substantial (>1 sentence) AND depth < D_max (20):

1. Create a NEW child .md file under the leaf's directory
2. Register child and convert former leaf to interior: echo '{"key":"","summary":""}' | bash core/scripts/tree-update.sh --add-child --encoding-source reflect-tree-update

   --encoding-source attributes the new child to the Shared Tree Update Protocol

   in meta/l1-pick-log.jsonl (S9). Auto-logging fires regardless; this enriches

   the entry. Pass --encoding-reason "" when there's a 1-line

   semantic justification worth capturing.

   The add-child enforces a pre-create dedup gate (Phase 2 curation).

   On exit 3 (summary overlap with an existing sibling under the new parent),

   read the rejected JSON from stderr for sibling_key and UPDATE that sibling

   in place with the new insight — do NOT retry with a different key.

   Exit 2 (exact key match) signals the new-child name collides with a sibling.

   bash core/scripts/tree-update.sh --set node_type interior
3. Move the original leaf content into a child if needed, then add the new child
4. Invoke /tree validate to check the structural change
