+# Statistics Page – Implementation Plan
+
+**Project:** Mila – Membership Management System  
+**Feature:** Statistics page at `/statistics`  
+**Scope:** MVP only (no export, no optional extensions)  
+**Last updated:** 2026-02-10
+
+---
+
+## Decisions (from clarification)
+
+| Topic | Decision |
+|-------|----------|
+| Route | `/statistics` |
+| Navigation | Top-level menu (next to Members, Fee Types) |
+| Permission | read_only, normal_user, admin (same as member list) |
+| Charts | HTML/CSS and SVG only (no Contex, no Chart.js) |
+| MVP scope | Minimal: active/inactive, joins/exits per year, contribution sums per year, open amount |
+| Open amount | Total unpaid only (no overdue vs. not-yet-due split in MVP) |
+
+Excluded from this plan: Export (CSV/PDF), caching, month/quarter filters, “members per fee type”, “members per group”, and overdue split.
+
+---
+
+## 1. Statistics module (`Mv.Statistics`)
+
+**Goal:** Central module for all statistics; LiveView only calls this API. Uses Ash reads with actor so policies apply.
+
+**Location:** `lib/mv/statistics.ex` (new).
+
+**Functions to implement:**
+
+| Function | Purpose | Data source |
+|----------|---------|-------------|
+| `active_member_count(opts)` | Count members with `exit_date == nil` | `Member` read with filter |
+| `inactive_member_count(opts)` | Count members with `exit_date != nil` | `Member` read with filter |
+| `joins_by_year(year, opts)` | Count members with `join_date` in given year | `Member` read, filter by year, count |
+| `exits_by_year(year, opts)` | Count members with `exit_date` in given year | `Member` read, filter by year, count |
+| `cycle_totals_by_year(year, opts)` | For cycles with `cycle_start` in year: total sum, and sums/counts by status (paid, unpaid, suspended) | `MembershipFeeCycle` read (filter by year via `cycle_start`), aggregate sum(amount) and count per status in Elixir or via Ash aggregates |
+| `open_amount_total(opts)` | Sum of `amount` for all cycles with `status == :unpaid` | `MembershipFeeCycle` read with filter `status == :unpaid`, sum(amount) |
+
+All functions accept `opts` (keyword list) and pass `actor: opts[:actor]` (and `domain:` where needed) to Ash calls. No new resources; only read actions on existing `Member` and `MembershipFeeCycle`.
+
+**Implementation notes:**
+
+- Use `Ash.Query.filter(Member, expr(...))` for date filters; for “year”, filter `join_date >= first_day_of_year` and `join_date <= last_day_of_year` (same for `exit_date` and for `MembershipFeeCycle.cycle_start`).
+- For `cycle_totals_by_year`: either multiple Ash reads (one per status) with sum aggregate, or one read of cycles in that year and `Enum.group_by(..., :status)` then sum amounts in Elixir.
+- Use `Mv.MembershipFees.CalendarCycles` only if needed for interval (e.g. cycle_end); for “cycle in year” the `cycle_start` year is enough.
+
+**Tests:** Unit tests in `test/mv/statistics_test.exs` for each function (with fixtures: members with join_date/exit_date, cycles with cycle_start/amount/status). Use `Mv.Helpers.SystemActor.get_system_actor()` in tests for Ash read authorization where appropriate.
+
+---
+
+## 2. Route and authorization
+
+**Router** ([lib/mv_web/router.ex](lib/mv_web/router.ex)):
+
+- In the same `ash_authentication_live_session` block where `/members` and `/membership_fee_types` live, add:
+  - `live "/statistics", StatisticsLive, :index`
+
+**PagePaths** ([lib/mv_web/page_paths.ex](lib/mv_web/page_paths.ex)):
+
+- Add module attribute `@statistics "/statistics"`.
+- Add `def statistics, do: @statistics`.
+- No change to `@admin_page_paths` (statistics is top-level).
+
+**Page permission** (route matrix is driven by [lib/mv/authorization/permission_sets.ex](lib/mv/authorization/permission_sets.ex)):
+
+- Add `"/statistics"` to the `pages` list of **read_only** (e.g. after `"/groups/:slug"`) and to the `pages` list of **normal_user** (e.g. after groups entries). **admin** already has `"*"` so no change.
+- **own_data** must not list `/statistics` (so they cannot access it).
+- Update [docs/page-permission-route-coverage.md](docs/page-permission-route-coverage.md): add row for `| /statistics | ✗ | ✓ | ✓ | ✓ |`.
+- Add test in `test/mv_web/plugs/check_page_permission_test.exs`: read_only and normal_user and admin can access `/statistics`; own_data cannot.
+
+---
+
+## 3. Sidebar
+
+**File:** [lib/mv_web/components/layouts/sidebar.ex](lib/mv_web/components/layouts/sidebar.ex).
+
+- In `sidebar_menu`, after the “Fee Types” menu item and before the “Administration” block, add a conditional menu item for Statistics:
+  - `can_access_page?(@current_user, PagePaths.statistics())` → show link.
+  - `href={~p"/statistics"}`, `icon="hero-chart-bar"` (or similar), `label={gettext("Statistics")}`.
+
+---
+
+## 4. Statistics LiveView
+
+**Module:** `MvWeb.StatisticsLive`  
+**File:** `lib/mv_web/live/statistics_live.ex`  
+**Mount:** `:index` only.
+
+**Behaviour:**
+
+- `on_mount`: use `MvWeb.LiveUserAuth, :live_user_required` and ensure role/permission check (same as other protected LiveViews). In `mount` or `handle_params`, set default selected year to current year (e.g. `Date.utc_today().year`).
+- **Assigns:** `:year` (integer), `:active_count`, `:inactive_count`, `:joins_this_year`, `:exits_this_year`, `:cycle_totals` (map with keys e.g. `:total`, `:paid`, `:unpaid`, `:suspended` for the selected year), `:open_amount_total`, and any extra needed for the bar data (e.g. list of `%{year: y, joins: j, exits: e}` for a small range of years if you show a minimal bar chart).
+- **Year filter:** A single select or dropdown for year (e.g. from “first year with data” to current year). On change, send event (e.g. `"set_year"`) with `%{"year" => year}`; in `handle_event` update `assigns.year` and reload data by calling `Mv.Statistics` again and re-assigning.
+
+**Data loading:**
+
+- In `mount` and whenever year changes, call `Mv.Statistics` with `actor: current_actor(socket)` (and optionally `year: @year` where needed). Assign results to socket. Handle errors (e.g. redirect or flash) if a call fails.
+
+**Layout (sections):**
+
+1. **Page title:** e.g. “Statistics” (gettext).
+2. **Year filter:** One control to select year; applies to “joins/exits” and “contribution sums” for that year.
+3. **Cards (top row):**
+   - Active members (count)
+   - Inactive members (count)
+   - Joins in selected year
+   - Exits in selected year
+   - Open amount total (sum of all unpaid cycles; format with `MvWeb.Helpers.MembershipFeeHelpers.format_currency/1`)
+   - Optionally: “Paid this year” (from `cycle_totals_by_year` for selected year)
+4. **Contributions for selected year:** One section showing for the chosen year: total (Soll), paid, unpaid, suspended (sums and optionally counts). Use simple table or key-value list; no chart required for MVP.
+5. **Joins / Exits by year (simple bar chart):** Data: e.g. last 5 or 10 years. For each year, show joins and exits as horizontal bars (HTML/CSS: e.g. `div` with `width: #{percent}%`). Pure HTML/SVG; no external chart library. Use Tailwind/DaisyUI for layout and cards.
+
+**Accessibility:** Semantic HTML; headings (e.g. `h2`) for each section; ensure year filter has a label; format numbers in a screen-reader-friendly way (e.g. no purely visual abbreviations without aria-label).
+
+**i18n:** All user-visible strings via gettext (e.g. “Statistics”, “Active members”, “Inactive members”, “Joins (year)”, “Exits (year)”, “Open amount”, “Contributions for year”, “Total”, “Paid”, “Unpaid”, “Suspended”). Add keys to `priv/gettext` as needed.
+
+---
+
+## 5. Implementation order (tasks)
+
+Execute in this order so that each step is testable:
+
+1. **Statistics module**
+   - Add `lib/mv/statistics.ex` with the six functions above and `@moduledoc`.
+   - Add `test/mv/statistics_test.exs` with tests for each function (use fixtures for members and cycles; pass actor in opts).
+   - Run tests and fix until green.
+
+2. **Route and permission**
+   - Add `live "/statistics", StatisticsLive, :index` in router.
+   - Add `statistics/0` and `@statistics` in PagePaths.
+   - Add `/statistics` to page permission logic so read_only, normal_user, admin are allowed and own_data is denied.
+   - Update `docs/page-permission-route-coverage.md` and add/update plug tests for `/statistics`.
+
+3. **Sidebar**
+   - Add Statistics link in sidebar (top-level) with `can_access_page?` and `PagePaths.statistics()`.
+
+4. **StatisticsLive**
+   - Create `lib/mv_web/live/statistics_live.ex` with mount, assigns, year param, and data loading from `Mv.Statistics`.
+   - Implement UI: title, year filter, cards, contribution section, simple joins/exits bar (HTML).
+   - Add gettext keys and use them in the template.
+   - Optionally add a simple LiveView test (e.g. authenticated user sees statistics page and key labels).
+
+5. **CI and docs**
+   - Run `just ci-dev` (or project equivalent); fix formatting, Credo, and tests.
+   - In [docs/feature-roadmap.md](docs/feature-roadmap.md), update “Reporting & Analytics” to reflect that a basic statistics page is implemented (MVP).
+   - In [CODE_GUIDELINES.md](CODE_GUIDELINES.md), add a short note under a suitable section (e.g. “Reporting” or “LiveView”) that statistics are provided by `Mv.Statistics` and displayed in `StatisticsLive`, if desired.
+
+---
+
+## 6. Out of scope (not in this plan)
+
+- Export (CSV/PDF).
+- Caching (ETS/GenServer/HTTP).
+- Month or quarter filters.
+- “Members per fee type” or “members per group” statistics.
+- Overdue vs. not-yet-due split for open amount.
+- Contex or Chart.js.
+- New database tables or Ash resources.
+
+These can be added later as separate tasks or follow-up plans.
