# scripts/generate-reports.sh
# Convenience wrapper: run both the profiler and the coverage report for a
# suite into a single timestamped directory under reports/.
#
# POSIX sh; works under mingw bash, WSL bash and Alpine/busybox ash.
#
# Usage:
#   scripts/generate-reports.sh [-s all|unit|integration] [-o OUTDIR]
#                               [-p] [-m MIN_PERCENT] [-t "file.sh ..."]
#
#   -s SUITE       suite to run (default: integration)
#   -o OUTDIR      base output directory (default: reports/run-<timestamp>)
#   -p             include per-line hotspots in the profile report
#   -m MIN_PERCENT coverage threshold to enforce (default: 0 = no gate)
#   -t LIST        space-separated target source files (default: trbldoc.sh)
