# TeamBrain — incremental CodeMap update (R16, opt-in)
#
# On merge to the default branch, re-summarize only the files that changed
# (hash-manifest diff) and commit the refreshed .teambrain/codemap/ tree
# directly — CodeMap is a derived artifact, not PR-gated (Tech Brief §4.8).
# Requires codemap.enabled: true in .teambrain/brain.yaml and an LLM key.
