# Seed 27 scenario-gap GitHub issues from scenario-gaps.json.
#
# Run from repo root. Requires `gh` (authenticated) and `jq`.
# Idempotent-ish: skips a gap if a same-titled open issue already exists.
#
# Usage:
#   scripts/seed-scenario-gap-issues.sh                # dry run, prints titles
#   scripts/seed-scenario-gap-issues.sh --apply        # actually create issues
#   scripts/seed-scenario-gap-issues.sh --apply --only SEC-01,DB-01
