# gstack-security-dashboard — community prompt-injection attack stats
#
# Reads the `security` section of the community-pulse edge function response
# (supabase/functions/community-pulse/index.ts). Shows aggregated attack
# data across all gstack users on telemetry=community.
#
# Call signature:
#   gstack-security-dashboard           # human-readable dashboard
#   gstack-security-dashboard --json    # machine-readable (CI / scripts)
#
# Env overrides (for testing):
#   GSTACK_DIR                    — override auto-detected gstack root
#   GSTACK_SUPABASE_URL           — override Supabase project URL
#   GSTACK_SUPABASE_ANON_KEY     — override Supabase anon key
