Greptile Summary

This PR couples schedule deployment with workflow deployment, removing the separate "Save" button for schedules.

Key Changes:

• Schedules are now automatically created/updated when a workflow is deployed and deleted when undeployed
• Removed the manual schedule save functionality (ScheduleSave component, use-schedule-management hook, POST /api/schedules)
• Added client-side pre-deploy validation that checks schedule configuration before allowing deployment
• New ScheduleInfo component displays read-only schedule status (next run, last run, failure count)
• Simplified /api/schedules/[id] route to only support reactivation of disabled schedules
• Added comprehensive validation functions in validation.ts for all schedule types
• Added extensive test coverage for the new schedule deploy utilities

Architecture: The change simplifies the schedule lifecycle by eliminating the need for users to manually save schedules. This reduces complexity and ensures schedules are always in sync with deployed workflows.

Confidence Score: 4/5

• This PR is safe to merge with good test coverage and clean architectural changes.
• Well-structured refactoring that simplifies the schedule management system. Comprehensive test coverage added. Minor code quality items noted in previous reviews (unused prop) but no critical issues.
• apps/sim/lib/workflows/schedules/deploy.ts - verify behavior with multiple schedule blocks is as intended

Important Files Changed

Filename	Overview
apps/sim/lib/workflows/schedules/deploy.ts	New file implementing schedule creation/deletion during workflow deployment. Uses upsert pattern with workflowId+blockId conflict target. Minor consideration: generates new UUID on each upsert but existing ID is preserved on conflict.
apps/sim/lib/workflows/schedules/validation.ts	New client-safe validation functions for schedule block configuration. Well-structured with proper validation for all schedule types.
apps/sim/app/api/workflows/[id]/deploy/route.ts	Modified to validate schedules before deployment and create schedule records during deploy. Deletes schedules within transaction on undeploy. Schedule creation happens outside transaction but with proper error handling.
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/deploy/hooks/use-deployment.ts	Enhanced deployment hook with client-side pre-deploy validation. Shows error notifications on validation failure. Clean implementation.
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/schedule-info/schedule-info.tsx	New read-only schedule status component replacing the old schedule-save. Shows cron description, next/last run times, and failure states with redeploy action.
apps/sim/app/api/schedules/route.ts	Simplified to GET-only endpoint. POST endpoint removed as schedule creation now happens during deployment.
apps/sim/app/api/schedules/[id]/route.ts	Simplified to PUT-only (reactivate action). DELETE removed as schedule deletion now handled during workflow undeploy.
