# SC6 content-retention decision — extracted from 99-dryrun.sh so the DROP detector (the deterministic
# guard against the llm-security 87-file-drop class, commit 836b8e9) is independently unit-testable
# (5d112cb). Given the extract's git-tracked file count, the live monorepo's count for the same paths, and
# whether an intentional >1MB blob-strip applies to this target, it prints the SC6 report-cell label and
# EXITS NON-ZERO on a real DROP — a shortfall NOT explained by a blob-strip. A blob-strip target may
# legitimately shed >1MB blobs, so a shortfall there is reported (exit 0), never failed.
#
# Usage: sc6-check.sh <ext_files> <live_files> <blob_strip>
#   blob_strip: True/true → intentional >1MB strip (shortfall allowed); anything else → shortfall = DROP.
