# node_pattern_refinement.py — Step 2 of Nelson's framework (PLACEHOLDER)
# ============================================================================
#
# PURPOSE (from Nelson 2020)
# --------------------------
# "The pattern refinement step returns to an interpretive engagement with
# the data through qualitative deep reading or further exploration of
# the data."
#
# Traditional grounded theory mapping: AXIAL CODING — the researcher
# examines discovered patterns, reads representative texts deeply, and
# refines cluster boundaries through interpretive judgment.
#
# STATUS
# ------
# This is a PLACEHOLDER. Real implementation requires human-in-the-loop
# UI (per-sentence reassignment, cluster renaming, noise rescue) that
# will be built in a subsequent round.
#
# When built, this node will:
# 1. Read state.detection_result
# 2. Present each cluster's representative sentences to the researcher
# 3. Let the researcher reassign sentences / rename clusters / merge
# or split clusters
# 4. Write the refined clustering back to state.refinement_result
