- FE-PR-003: Essential create/edit modal with type selector and partial refresh already implemented in ProposalDetailPage
- FE-PR-004: Accept modal with milestone selector and generated tasks display already implemented
- FE-PR-005: Remove 'story' from TASK_TYPES in CreateTaskPage and CreateTaskModal - all story/* must come from Proposal Accept workflow
- PATCH /calendar/plans/{plan_id}: edit a recurring schedule plan
- Validates period-parameter hierarchy after merge
- Rejects edits to inactive (cancelled) plans
- Detaches future materialized slots so they keep old data
- Past materialized slots remain untouched
- POST /calendar/plans/{plan_id}/cancel: cancel (soft-delete) a plan
- Sets is_active=False
- Detaches future materialized slots (plan_id -> NULL)
- Preserves past materialized slots, returns their IDs
- Added SchedulePlanEdit and SchedulePlanCancelResponse schemas
- Imported guard_plan_edit/cancel_no_past_retroaction from slot_immutability
- Add POST /calendar/slots/{slot_id}/cancel for real slot cancellation
- Add POST /calendar/slots/virtual/{virtual_id}/cancel for virtual slot cancellation
- Virtual cancel materializes the slot first, then marks as Skipped
- Both endpoints enforce past-slot immutability guard
- Both endpoints detach from plan (set plan_id=NULL)
- Status set to SlotStatus.SKIPPED on cancel
- Add TimeSlotCancelResponse schema
- Import guard_cancel_real_slot and guard_cancel_virtual_slot
- Add GET /calendar/day endpoint with optional ?date= query param
- Returns unified CalendarDayResponse merging real slots + virtual plan slots
- New CalendarSlotItem schema supports both real (id) and virtual (virtual_id) slots
- Excludes inactive slots (skipped/aborted) from results
- All slots sorted by scheduled_at ascending
- Add TimeSlotCreate, TimeSlotResponse, TimeSlotCreateResponse schemas
- Add SlotConflictItem, SlotTypeEnum, EventTypeEnum, SlotStatusEnum to schemas
- Add POST /calendar/slots endpoint with:
- Overlap detection (409 on conflict)
- Workload warning computation (advisory, returned in response)
- Support for event_type + event_data (job/system/entertainment)
- Default date to today if not provided
- Add _slot_to_response helper for ORM -> schema conversion
- Virtual slot ID: plan-{plan_id}-{YYYY-MM-DD} format with parse/make helpers
- Plan-date matching: on_month/on_week/on_day hierarchy with week_of_month calc
- Materialization: convert virtual slot to real TimeSlot row, copy plan template
- Detach: clear plan_id after edit/cancel to break plan association
- Bulk materialization: materialize_all_for_date for daily pre-compute
- 23 tests covering all paths (matching, virtual gen, materialize, detach, bulk)
Decision: retain DB column, mark DEPRECATED. Existing rows still return
feat_task_id via API. New accept flow (BE-PR-007) does not write it.
Clients should migrate to generated_tasks / Task.source_proposal_id.
- Backend: model/schema/router deprecation comments updated
- Backend: added docs/BE-PR-010-feat-task-id-deprecation.md
- Tests: updated to work with Essential-based accept flow
- Tests: all 21 proposal tests pass
- TASKLIST: BE-PR-010 marked complete
