Hard rules

1. The calendar must merge three sources in its agenda view: calendar_items, social_posts (status in draft|scheduled with scheduled_at IS NOT NULL), email_campaigns (status in draft|approved with scheduled_at IS NOT NULL). Don't drop any source without owner OK.
2. Never push to a real external calendar (Google Calendar, Outlook, etc.) without:
   • OAuth client id + secret already configured in Supabase Auth providers
   • ALLOW_CALENDAR_SYNC=true (or equivalent) env flag, which today does not exist — that's an explicit sprint to add
   • Owner-clicked "Sync calendar" button
3. Calendar items have an item_type (suggested values: reminder, meeting, task, content_milestone). Add new types via an enum migration; never via free-form string.
4. Don't mutate social_posts.scheduled_at or email_campaigns.scheduled_at from the calendar surface. Editing those rows is the marketing-studio-builder's territory.
5. Time zones: the database stores UTC. The UI renders in browser local TZ. The form uses native <input type="datetime-local"> which is local. Convert via new Date(value).toISOString() only at submit.
6. Don't create recurring-event infrastructure unless explicitly asked — that's a serious schema move.

Project context

• calendar_items table columns of interest: id, user_id, organization_id, title, description, starts_at, ends_at, item_type, metadata, created_at, updated_at.
• Owner sees all rows in the org. Other roles see their own rows + team-shared via RLS.
• Dashboard already reads calendar_items + scheduled social/email for the next 7 days into an upcoming array. Keep that contract stable.
• Brand: "Plan Content" is the user-visible label for the Calendar entry on Quick Launch.

Working method

1. Read brief. Decide whether it's view (week/agenda/month layout) or data (new column / new metadata field).
2. For view changes: edit app/(app)/calendar/page.tsx. Use server-side data fetching (force-dynamic). Group by day for agenda view, by week for week view, by month for month view. Don't add date-fns features beyond what's already imported.
3. For data changes: extend the schema in CreateCalendarItem.tsx + the matching INSERT. Persist new fields in metadata jsonb unless they're queryable, in which case add a column via a migration owned by the user.
4. Confirm with a manual create → re-fetch → see in agenda flow. Use /calendar directly via dev server.
5. Hand to integrator with the new view name or the new metadata key.

Verification checklist

• Agenda / week / month view renders without crash on an empty database AND on a database with 30+ items.
• Scheduled social drafts visible on the right day.
• Scheduled email campaigns visible on the right day.
• No external calendar API call made.
• Time-zone math: a row scheduled at "Mon 9am PT" shows on Monday for a viewer in PT and Tuesday only if they're in a +12 TZ. Spot-check with new Date(scheduled_at).toLocaleString().

Final output format

View: agenda | week | month
Files: <comma list>
Sources merged: calendar_items | social_posts | email_campaigns
Item count rendered: <number>
External calendar sync: still off (no creds yet)
