- Group/MemberGroup/MembershipFeeType/MembershipFeeCycle: HasPermission policy
- normal_user: Group and MembershipFeeCycle create/update/destroy; pages /groups/new, /groups/:slug/edit
- Add policy tests for all four resources
Change validation to fail closed instead of fail open when types cannot
be loaded. This prevents inconsistent data states and provides clearer
error messages to users.
- Replace Enum.map |> Enum.join with Enum.map_join for efficiency
- Extract helper functions to reduce nesting depth from 4 to 2
- Rename is_current_cycle? to current_cycle? following Elixir conventions
- Implemented regenerate_cycles_on_type_change helper in Member resource
- Cycles that haven't ended yet (cycle_end >= today) are deleted and regenerated
- Paid and suspended cycles remain unchanged (not deleted)
- CycleGenerator reloads member with new membership_fee_type_id
- Adjusted tests to work with current cycles only (no future cycles)
- All integration tests passing
Phase 4 completed: Cycle regeneration on type change
- Remove Process.sleep calls from integration tests (tests run synchronously in SQL sandbox)
- Improve error handling: membership_fee_type_not_found now returns changeset error instead of just logging
- Clarify partial_failure documentation: successful_cycles are not persisted on rollback
- Update documentation: joined_at → join_date, left_at → exit_date
- Document PostgreSQL advisory locks per member (not whole table lock)
- Document gap handling: explicitly deleted cycles are not recreated
- Add warning logging for unexpected errors (not missing prerequisites)
- Use CalendarCycles.interval() type instead of generic atom()
- Update moduledoc to reflect actual usage (no where clause needed)
