# Task EP.1.6.1 Calendar Empty State Rendering Improvement - 2026-07-13

## Scope Delivered

- updated Calendar Day, Week, and Month views to always render calendar grid cells even when there are zero events
- kept Agenda view list-oriented empty state behavior unchanged
- added inline empty overlay for Day/Week/Month instead of replacing the calendar surface
- added `+ Add Activity` entry point from empty calendar overlay using existing Activity workspace route
- kept date/time rendering through `src/lib/date-format.ts`
- preserved Calendar projection, Activity ownership, and Calendar adapter architecture

## Review Summary

Reviewed before implementation:

- `AGENTS.md`
- `plans/task-ep.1.6.1.md`
- `docs/implementation/task-ep1.6-calendar-projection-workspace-big-calendar-foundation-2026-07-13.md`
- `docs/implementation/task-ep1.7-my-day-workspace-foundation-2026-07-13.md`
- `src/features/crm/calendar/components/calendar-workspace.tsx`
- Calendar API contracts under `src/features/crm/calendar/api/types.ts`

## Implementation Notes

- Day view now renders 12 working-hour slots.
- Week view now renders seven day cells.
- Month view now renders a 42-cell month grid.
- Empty Day/Week/Month views show a lightweight non-blocking overlay with Add Activity action.
- Calendar cells remain rendered and selectable via button semantics.
- Agenda retains `CalendarEmptyState` because a list view should show a list empty state.

## Verification

- `npm run typecheck`
- `npx oxlint src/features/crm/calendar/components/calendar-workspace.tsx`

## Outcome

Empty graphical Calendar views now feel like available scheduling capacity rather than a missing screen.
