 # Technical Changelog

+## 2026-04-28 - Phase 110 Plan 01: Statistics Summary
+
+**Co zrobiono:**
+- `/statistics/summary` - nowy widok podsumowania w menu `Statystyki -> Podsumowanie`.
+- `OrdersStatisticsController::summary()` - buduje miesieczny view-model dla wykresow liczby i wartosci zamowien.
+- `OrdersStatisticsRepository::aggregateByMonth()` - agreguje istniejace zamowienia po miesiacu i kanale/integracji.
+- `public/assets/js/modules/statistics-summary-charts.js` - renderer dwoch interaktywnych wykresow liniowych oparty o Chart.js 4.4.8 CDN.
+- `resources/views/statistics/summary.php` - filtry zgodne z raportem dziennym, dwa wykresy obok siebie na desktopie oraz dwie tabele fallback pod nimi.
+- Domyslny poczatek historii ustawiony na `2026-04-01` (`04-2026`) mimo starszych danych.
+
+**Dlaczego:**
+- Operator potrzebuje szybkiego trendu miesiecznego przed przejsciem do szczegolowych dziennych statystyk.
+- Wykresy uzywaja obecnych tabel `orders`, `integrations`, `order_status_groups` i `order_statuses`, wiec migracja DB nie jest potrzebna.
+- Seria `Razem` jest liczona z tych samych danych co serie integracji, co ulatwia sprawdzenie sum miesiecznych.

+## Goal
+Add a new first submenu item `Statystyki -> Podsumowanie` with two monthly line charts:
+- monthly order count per integration plus a total line,
+- monthly order value per integration plus a total line.
+
+## Purpose
+The operator needs a quick trend view before opening detailed daily order statistics. The summary should show how each sales integration contributes month by month and how the total business volume changes over time.
+
+## Output
+- New authenticated endpoint `/statistics/summary`.
+- Sidebar order: `Podsumowanie` first, existing `Zamowienia` second.
+- New summary view with compact filters and two charts.
+- Backend monthly aggregation using existing orders data, grouped by integration/channel.
+- Technical documentation updates. No database migration is expected.

+- Existing statistics code already has filter parsing patterns, channel labels, status group defaults, collation handling, and amount fallback logic. Reuse those rather than creating a separate query style.
+- `SPECIAL-FLOWS.md` requires `sonar-scanner` after APPLY and before UNIFY; frontend-design is optional for this UI work.

+<acceptance_criteria>
+
+## AC-1: Sidebar Navigation
+```gherkin
+Given the user is authenticated
+When the sidebar statistics section is visible
+Then the first item under "Statystyki" is "Podsumowanie"
+And the second item remains "Zamowienia"
+And clicking "Podsumowanie" opens `/statistics/summary`
+And the active state highlights "Podsumowanie" on that page
+```
+
+## AC-2: Monthly Order Count Chart
+```gherkin
+Given orders exist across multiple months and integrations
+When the user opens `/statistics/summary`
+Then the page shows an order count chart grouped by month
+And each integration has its own line
+And an additional "Razem" line sums all selected integrations per month
+```
+
+## AC-3: Monthly Order Value Chart
+```gherkin
+Given orders exist across multiple months and integrations
+When the user opens `/statistics/summary`
+Then the page shows an order value chart grouped by month
+And each integration has its own line
+And an additional "Razem" line sums all selected integrations per month
+And values are displayed as money with two decimal places
+```
+
+## AC-4: Existing Statistics Semantics Reused
+```gherkin
+Given the user changes the date range, channel selection, or status group selection
+When the summary page reloads
+Then both charts use the same selected filters
+And channel labels match existing statistics labels
+And default status groups still exclude the cancelled group
+```
+
+## AC-5: Empty and Degraded States
+```gherkin
+Given the selected filters return no orders
+When the user opens `/statistics/summary`
+Then the page shows a clear empty state instead of broken charts
+
+Given JavaScript fails to load
+When the user opens `/statistics/summary`
+Then the monthly data remains visible in an HTML table fallback

+    - Add repository method `aggregateByMonth(string $dateFrom, string $dateTo, array $channels, array $statusCodes): array`.
+    - The query must reuse the existing effective date, channel, gross amount, and status SQL semantics from `aggregateByDay()`.
+    - Group rows by `DATE_FORMAT(effective_date, "%Y-%m")` and channel key.

+## DO NOT CHANGE
+- Import/synchronization modules for Allegro/shopPRO.
+- Existing `/statistics/orders` route contract and GET parameter names.
+- Database migrations unless a blocker proves the existing schema cannot support the charts.
+- Runtime DB env behavior: do not wire `DB_HOST_REMOTE` into application runtime.
+
+## SCOPE LIMITS
+- This plan adds only summary charts for orders. It does not add exports, product charts, inventory charts, or accounting reports.
+- Values chart uses the existing gross amount semantics from current order statistics unless the user explicitly asks for net values.
+- Chart interactivity is limited to readable lines/legend/tooltips if implemented locally; advanced drill-down is out of scope.
+- No new native alerts or confirms.

+# Phase 110 Plan 01: Statistics Summary
+
+Monthly statistics summary shipped with two interactive Chart.js line charts, compact filters, per-integration series, total series, and table fallbacks.
+
+## Performance
+
+| Metric | Value |
+|--------|-------|
+| Duration | ~90min |
+| Started | 2026-04-28T22:20:00+02:00 |
+| Completed | 2026-04-28T23:50:00+02:00 |
+| Tasks | 3 auto tasks + 1 human verification checkpoint |
+| Files modified | 18 |
+
+## Acceptance Criteria Results
+
+| Criterion | Status | Notes |
+|-----------|--------|-------|
+| AC-1: Sidebar Navigation | Pass | `Podsumowanie` added first under `Statystyki`; `/statistics/summary` route registered with active state. |
+| AC-2: Monthly Order Count Chart | Pass | Count chart model contains one dataset per selected integration plus `Razem`; rendered by Chart.js. |
+| AC-3: Monthly Order Value Chart | Pass | Value chart model contains one dataset per selected integration plus `Razem`; values formatted as money in tooltips/table. |
+| AC-4: Existing Statistics Semantics Reused | Pass | Controller reuses channel/status filter flow; repository reuses effective date/channel/status/gross SQL helpers. |
+| AC-5: Empty and Degraded States | Pass | Empty state shown when no data; tables remain visible as fallback below charts. |
+
+## Accomplishments
+
+- Added authenticated `/statistics/summary` page with monthly order count and order gross value charts.
+- Added `OrdersStatisticsRepository::aggregateByMonth()` using prepared parameters and existing statistics SQL helper semantics.
+- Added `OrdersStatisticsController::summary()` and a chart/table view-model with total lines.
+- Updated sidebar navigation, translations, SCSS, compiled CSS, and Chart.js frontend module.
+- Created root `DOCS/` technical documentation required by `AGENTS.md` and synchronized it with `.paul/codebase/`.

+
+## Decisions Made
+
+| Decision | Rationale | Impact |
+|----------|-----------|--------|
+| Start history at `2026-04-01` | User requested `04-2026` as hard start despite older data. | Default summary excludes older months unless code changes later. |
+| Use Chart.js 4.4.8 CDN | User requested an interactive JS library; project already uses CDN for Quill. | No npm dependency or build pipeline change. |
+| Use gross order values | Existing statistics gross semantics are stable and already documented. | Value chart matches current order statistics totals. |
+| Keep table fallback | Required degraded state and useful for verification. | Data remains visible without Chart.js/JS. |
+
+## Deviations from Plan
+
+| Type | Count | Impact |
+|------|-------|--------|
+| Scope adjustments from user feedback | 3 | Improved UI and changed default date semantics. |
+| Environment blockers | 3 | Verification limits only; code/build checks passed. |
+
+**Total impact:** Controlled deviations; feature outcome matches latest user request.
+
+### Adjusted During APPLY
+
+**Chart renderer changed to Chart.js**
+- Found during user feedback after APPLY.
+- Fix: Added Chart.js CDN and rewrote `statistics-summary-charts.js` to use Chart.js legends/tooltips.
+- Verification: `node --check`, PHP lint, CSS build, Sonar scan.
+
+**Desktop layout split**
+- Found during user feedback after APPLY.
+- Fix: Added two-column chart grid and two-column table grid from 1100px.
+- Verification: PHP lint and CSS build.
+
+**Default history start**
+- Found during user feedback after APPLY.
+- Fix: Set summary default `date_from` to `2026-04-01`.
+- Verification: PHP lint.
+
+### Deferred Items
+
+- SonarQube issue import into `DOCS/todo.md` was not performed because no SonarQube MCP resources/tools are available in this Codex session.
+- Full authenticated HTTP verification was not possible locally because MySQL/XAMPP refused the DB connection.
+- PHPUnit was not run because `composer` is not available in PATH and `vendor/` is absent.
+
+## Issues Encountered
+
+| Issue | Resolution |
+|-------|------------|
+| Local bootstrap failed with MySQL connection refused. | Started PHP dev server anyway; documented DB blocker. |
+| `composer test` unavailable. | Documented test blocker; ran available lint/build/static checks. |
+| Sonar MCP unavailable. | Ran `sonar-scanner` successfully and documented inability to fetch issue details. |
+
+## Verification Results
+
+| Check | Result |
+|-------|--------|
+| `php -l src/Modules/Statistics/OrdersStatisticsController.php` | Pass |
+| `php -l src/Modules/Statistics/OrdersStatisticsRepository.php` | Pass |
+| `php -l routes/web.php` | Pass |
+| `php -l resources/views/layouts/app.php` | Pass |
+| `php -l resources/views/statistics/summary.php` | Pass |
+| `php -l resources/lang/pl.php` | Pass |
+| `node --check public/assets/js/modules/statistics-summary-charts.js` | Pass |
+| `npm run build:css` | Pass |
+| `sonar-scanner` | Pass; report uploaded to SonarQube |
+| Local `/statistics/summary` HTTP 200 | Blocked by local MySQL connection refused |
+| `composer test` / PHPUnit | Blocked: `composer` not in PATH and `vendor/` absent |
+
+## Skill Audit
+
+| Expected | Invoked | Notes |
+|----------|---------|-------|
+| `sonar-scanner` | yes | Ran successfully after APPLY changes. |
+
+## Next Phase Readiness
+
+**Ready:**
+- Statistics summary page exists and is wired into sidebar navigation.
+- Monthly aggregation pattern can be reused for future reporting charts.
+- Root `DOCS/` docs now exist for future AGENTS.md-compliant changes.
+
+**Concerns:**
+- Chart.js is CDN-based; if offline operation becomes required, vendor locally or add npm build support.
+- Local verification depends on XAMPP/MySQL being available.
+- Sonar issue import still needs a working SonarQube MCP/tool path.
+
+**Blockers:**
+- None for closing Phase 110.
