# 🍝 jscpd — deterministic copy-paste/duplication scan.
#
# Runs jscpd against this repo and uploads the full JSON+HTML report, plus
# the report split into BUCKET_COUNT small JSON files, so a caller can
# download one small bucket at random per invocation instead of the full
# report (which can run into tens of MB on a monorepo this size).
#
# Reporters/ignores/threshold come from this repo's own .jscpd.json; this
# workflow passes none of those flags itself.
