The migrate-deploy.ts script was throwing an error when the drizzle migration journal was not found. This caused worker deployments to fail when: 1. The .dockerignore excludes the drizzle/ folder 2. The worker service uses the same railway.json as the API Now the script gracefully exits with success (exit code 0) when the migration journal is not found, logging a warning message. This is expected behavior for worker deployments which don't need to run migrations - only the API service should handle migrations. Co-authored-by: armin.naimi <[email redacted]>

The deploy migration script now: - Uses bunx drizzle-kit migrate for actual migration execution - Only handles connection retries and db:push detection as a wrapper - Drizzle Kit manages transactions and SQL execution properly This is safer than custom SQL parsing and execution. Co-authored-by: armin.naimi <[email redacted]>

This commit introduces a robust migration system that handles: - Fresh databases and databases set up with db:push - Automatic migration running on Railway deployments - Connection retries with exponential backoff - Clear diagnostics and logging Changes: - Add scripts/migrate-deploy.ts: Deploy-safe migration script with retry logic - Add scripts/sync-migrations.ts: Tool to sync migrations with database state - Update scripts/check-migrations.ts: Better diagnostics and JSON output - Update railway.json: Run migrations before app starts - Update package.json: Add new migration commands - Update _journal.json: Add missing 0017_password_reset_tokens entry - Update RAILWAY.md: Document new migration workflow - Update LIVE_MIGRATION_STRATEGY.md: Document deploy migration script New commands: - bun run db:migrate:deploy - Deploy-safe migration with retries - bun run db:sync status|mark-all|reset|introspect - Migration sync tools - bun run db:check --json|--verbose|--fix - Enhanced migration checking Co-authored-by: armin.naimi <[email redacted]>

Pass the current form state (name, description) to AICoverGenerator instead of the saved pack values. This allows users to update the pack name or description and have those changes reflected in the AI cover generation without needing to save first. Co-authored-by: armin.naimi <[email redacted]>

- Changed floatingConfig from function to object form to match other working popover implementations (Header, WorkspaceSwitcher, SequencerTrack) - Removed external 'open' state management in favor of popover's internal state - Moved state reset logic to () that reacts to popover.open changes - This fixes the issue where the popover appeared at top-left of screen instead of positioned relative to the trigger button Co-authored-by: armin.naimi <[email redacted]>

- Change reasoningEffort from "none" to "minimal" in both ai-tagging and audio-analysis services to enhance AI processing capabilities.
