+-- Migration 018: Model Visibility
+-- ==========================================
+-- Replace binary is_enabled with three-state visibility:
+--   'enabled'  — visible to all users in model selector
+--   'disabled' — hidden from everyone
+--   'team'     — only available to team admins for building presets
+-- ==========================================
+
+-- Add new column (idempotent)
+ALTER TABLE model_configs ADD COLUMN IF NOT EXISTS visibility VARCHAR(10) DEFAULT 'disabled';
+
+-- Backfill from is_enabled if it still exists
