+# 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.
