2580aa5e0d docs: extract frontend design rules and add presentation persistence fix 
Create FRONTEND_DESIGN_RULES.md as the single source of truth for all dashboard
UI conventions, including component library (Syncfusion first), component defaults
table, layout structure, buttons, dialogs, badges, toasts, form fields, tabs,
statistics cards, warnings, color palette, CSS files, loading states, locale
rules, and icon conventions (TentTree for skip-holidays events).

Move embedded design rules from ACADEMIC_PERIODS_CRUD_BUILD_PLAN.md to the new
file and replace with a reference link for maintainability.

Update copilot-instructions.md to point to FRONTEND_DESIGN_RULES.md and remove
redundant Syncfusion/Tailwind prose from the Theming section.

Add reference blockquote to README.md under Frontend Features directing readers
to FRONTEND_DESIGN_RULES.md.

Bug fix: Presentation events now reliably persist page_progress and auto_progress
flags across create, update, and detached occurrence flows so display settings
survive round-trips to the API.

Files changed:
- Created: FRONTEND_DESIGN_RULES.md (15 sections, 340+ lines)
- Modified: ACADEMIC_PERIODS_CRUD_BUILD_PLAN.md (extract rules, consolidate)
- Modified: .github/copilot-instructions.md (link to new rules file)
- Modified: README.md (reference blockquote)

Imports and manual saves validate date ranges against the selected academic period, prevent duplicates, auto-merge same normalized name+region overlaps (including adjacent ranges), and report conflicting overlaps.

- Dev Container: When adding frontend deps, prefer `npm ci` and, if using named volumes, recreate dashboard `node_modules` volume so installs occur inside the container.
- Theming: Syncfusion Material 3 theme is used.

### Recurrence & holidays: conventions
- Do not pre-expand recurrences on the backend. Always send master events with `RecurrenceRule` + `RecurrenceException`.
- Ensure EXDATE tokens are RFC 5545 timestamps (`yyyyMMddTHHmmssZ`) matching the occurrence start time (UTC) so Syncfusion can exclude them natively.
- When `skip_holidays` or recurrence changes, regenerate `EventException` rows so `RecurrenceException` stays in sync.
- School holidays are scoped by `academic_period_id`; holiday imports and queries should use the relevant academic period rather than treating holiday rows as global.
- Holiday write operations (manual/import) must validate date ranges against the selected academic period.
- Overlap policy: same normalized `name+region` overlaps (including adjacent ranges) are merged; overlaps with different identity are conflicts (manual blocked, import skipped with details).
- When `skip_holidays` or recurrence changes, regenerate `EventException` rows so `RecurrenceException` stays in sync, using the event's `academic_period_id` holidays (or only unassigned holidays for legacy events without a period).
- Single occurrence detach: Use `POST /api/events/<id>/occurrences/<date>/detach` to create standalone events and add EXDATE entries without modifying master events. The frontend persists edits via `actionComplete` (`requestType='eventChanged'`).

## Academic Periods System
- **Purpose**: Organize events and media by educational cycles (school years, semesters, trimesters).
- **Purpose**: Organize events and media by educational cycles (school years, semesters, trimesters) with full lifecycle management.
- **Design**: Fully backward compatible - existing events/media continue to work without period assignment.
- **Usage**: New events/media can optionally reference `academic_period_id` for better organization and filtering.
- **Constraints**: Only one period can be active at a time; use `init_academic_periods.py` for Austrian school year setup.
- **UI Integration**: The dashboard highlights the currently selected period and whether a holiday plan exists within that date range. Holiday linkage currently uses date overlap with `school_holidays`; an explicit `academic_period_id` on `school_holidays` can be added later if tighter association is required.
- **Lifecycle States**:
- Active: exactly one period at a time (all others deactivated when activated)
- Inactive: saved period, not currently active
- Archived: soft-deleted; hidden from normal list; can be restored
- Deleted: hard-deleted; permanent removal (only when no linked events exist and no active recurrence)
- **Archive Rules**: Cannot archive active periods or periods with recurring master events that have current/future occurrences
- **Delete Rules**: Only archived inactive periods can be hard-deleted; blocked if linked events exist
- **Validation Rules**:
- Name: required, trimmed, unique among non-archived periods
- Dates: startDate ≤ endDate
- Type: schuljahr, semester, or trimester
- Overlaps: disallowed within same periodType (allowed across types)
- **Recurrence Spillover Detection**: Archive/delete blocked if recurring master events assigned to period still generate current/future occurrences
- **Model Fields**: `id`, `name`, `display_name`, `start_date`, `end_date`, `period_type`, `is_active`, `is_archived`, `archived_at`, `archived_by`, `created_at`, `updated_at`
- **Events/Media Association**: Both `Event` and `EventMedia` have optional `academic_period_id` FK for organizational grouping
- **UI Integration** (`dashboard/src/settings.tsx` > 🗂️ Perioden):
- List with badges (Active/Archived)
- Create/Edit dialogs with validation
- Activate, Archive, Restore, Delete actions with blocker preflight checks
- Archive visibility toggle to show/hide retired periods
- Error dialogs showing exact blockers (linked events, active recurrence, active status)

# Frontend Design Rules
This file is the single source of truth for UI implementation conventions in the dashboard (`dashboard/src/`).
It applies to all feature work, including new pages, settings tabs, dialogs, and management surfaces.
When proposing or implementing frontend changes, follow these rules unless a specific exception is documented below.
This file should be updated whenever a new Syncfusion component is adopted, a color or pattern changes, or an exception is ratified.
---
## 1. Component Library — Syncfusion First
Use Syncfusion components as the default choice for every UI element.
The project uses the Syncfusion Material3 theme, registered globally in `dashboard/src/main.tsx`.
The following CSS packages are imported there and cover all components currently in use:
`base`, `navigations`, `buttons`, `inputs`, `dropdowns`, `popups`, `kanban`, `grids`, `schedule`, `filemanager`, `notifications`, `layouts`, `lists`, `calendars`, `splitbuttons`, `icons`.
When adding a new Syncfusion component, add its CSS import here — and add the new npm package to `optimizeDeps.include` in `vite.config.ts` to avoid Vite import-analysis errors in development.
Use non-Syncfusion elements only when:
- The Syncfusion equivalent does not exist (e.g., native `<input type="file">` for file upload)
- The Syncfusion component would require significantly more code than a simple HTML element for purely read-only or structural content (e.g., `<ul>/<li>` for plain lists)
- A layout-only structure is needed (a wrapper `<div>` for spacing is fine)
**Never** use `window.confirm()` for destructive action confirmations — use `DialogComponent` instead.
`window.confirm()` exists in one place in `dashboard.tsx` (bulk restart) and is considered a deprecated pattern to avoid.
Do not introduce Tailwind utility classes — Tailwind has been removed from the project.
---
## 2. Component Defaults by Purpose
| Purpose | Component | Notes |
|---|---|---|
| Navigation tabs | `TabComponent` + `TabItemDirective` | `heightAdjustMode="Auto"`, controlled with `selectedItem` state |
| Data list or table | `GridComponent` | `allowPaging`, `allowSorting`, custom `template` for status/actions |
| Paginated list | `PagerComponent` | When a full grid is too heavy; default page size 5 or 10 |
| Text input | `TextBoxComponent` | Use `cssClass="e-outline"` on form-heavy sections |
| Numeric input | `NumericTextBoxComponent` | Always set `min`, `max`, `step`, `format` |
| Single select | `DropDownListComponent` | Always set `fields={{ text, value }}`; do **not** add `cssClass="e-outline"` — only `TextBoxComponent` uses outline style |
| Boolean toggle | `CheckBoxComponent` | Use `label` prop, handle via `change` callback |
| Buttons | `ButtonComponent` | See section 4 |
| Modal dialogs | `DialogComponent` | `isModal={true}`, `showCloseIcon={true}`, footer with Cancel + primary |
| Notifications | `ToastComponent` | Positioned `{ X: 'Right', Y: 'Top' }`, 3000ms timeout by default |
| Inline info/error | `MessageComponent` | Use `severity` prop: `'Error'`, `'Warning'`, `'Info'`, `'Success'` |
| Status/role badges | Plain `<span>` with inline style | See section 6 for convention |
| Timeline/schedule | `ScheduleComponent` | Used for resource timeline views; see `ressourcen.tsx` |
| File management | `FileManagerComponent` | Used on the Media page for upload and organisation |
| Drag-drop board | `KanbanComponent` | Used on the Groups page; retain for drag-drop boards |
| User action menu | `DropDownButtonComponent` (`@syncfusion/ej2-react-splitbuttons`) | Used for header user menu; add to `optimizeDeps.include` in `vite.config.ts` |
| File upload | Native `<input type="file">` | No Syncfusion equivalent for raw file input |
---
## 3. Layout and Card Structure
Every settings tab section starts with a `<div style={{ padding: 20 }}>` wrapper.
Content blocks use Syncfusion card classes:
```jsx
<div className="e-card">
<div className="e-card-header">
<div className="e-card-header-caption">
<div className="e-card-header-title">Title</div>
</div>
</div>
<div className="e-card-content">
{/* content */}
</div>
</div>
```
Multiple cards in the same tab section use `style={{ marginBottom: 20 }}` between them.
For full-page views (not inside a settings tab), the top section follows this pattern:
```jsx
<div style={{ marginBottom: 24, display: 'flex', justifyContent: 'space-between', alignItems: 'center' }}>
<div>
<h2 style={{ margin: 0, fontSize: 24, fontWeight: 600 }}>Page title</h2>
<p style={{ margin: '8px 0 0 0', color: '#6c757d' }}>Subtitle or description</p>
</div>
<ButtonComponent cssClass="e-success" iconCss="e-icons e-plus">New item</ButtonComponent>
</div>
```
---
## 4. Buttons
| Variant | `cssClass` | When to use |
|---|---|---|
| Primary action (save, confirm) | `e-primary` | Main save or confirm in forms and dialogs |
| Create / add new | `e-success` + `iconCss="e-icons e-plus"` | Top-level create action in page header |
| Destructive (delete, archive) | `e-flat e-danger` | Row actions and destructive dialog confirm |
| Secondary / cancel | `e-flat` | Cancel in dialog footer, low-priority options |
| Info / edit | `e-flat e-primary` or `e-flat e-info` | Row-level edit and info actions |
| Outline secondary | `e-outline` | Secondary actions needing a visible border (e.g., preview URL) |
All async action buttons must be `disabled` during the in-flight operation: `disabled={isBusy}`.
Button text must change to indicate the pending state: `Speichere…`, `Erstelle...`, `Archiviere…`, `Lösche...`.
---
## 5. Dialogs
All create, edit, and destructive action dialogs use `DialogComponent`:
- `isModal={true}`
- `showCloseIcon={true}`
- `width="500px"` for forms (wider if tabular data is shown inside)
- `header` prop with specific context text (include item name where applicable)
- `footerTemplate` always has at minimum: Cancel (`e-flat`) + primary action (`e-primary`)
- Dialog body wrapped in `<div style={{ padding: 16 }}>`
- All fields disabled when `formBusy` is true
For destructive confirmations (archive, delete), the dialog body must clearly explain what will happen and whether it is reversible.
For blocked actions, use `MessageComponent` with `severity="Warning"` or `severity="Error"` inside the dialog body to show exact blocker details (e.g., linked event count, recurrence spillover).
---
## 6. Status and Type Badges
Plain `<span>` badges with inline style — no external CSS classes needed:
```jsx
<span style={{
padding: '4px 12px',
borderRadius: '12px',
backgroundColor: color,
color: 'white',
fontSize: '12px',
fontWeight: 500,
display: 'inline-block',
}}>
Label
</span>
```
See section 12 for the fixed color palette.
**Icon conventions**: Use inline SVG or icon font classes for small visual indicators next to text. Established precedents:
- Skip-holidays events render a TentTree icon immediately to the left of the main event-type icon; **always black** (`color: 'black'` or no color override).
- Recurring events rely on Syncfusion's native lower-right recurrence badge — do not add a custom recurrence icon.
**Role badge color mapping** (established in `users.tsx`; apply consistently for any role display):
| Role | Color |
|---|---|
| user | `#6c757d` (neutral gray) |
| editor | `#0d6efd` (info blue) |
| admin | `#28a745` (success green) |
| superadmin | `#dc3545` (danger red) |
---
## 7. Toast Notifications
Use a component-local `ToastComponent` with a `ref`:
```jsx
const toastRef = React.useRef<ToastComponent>(null);
// ...
<ToastComponent ref={toastRef} position={{ X: 'Right', Y: 'Top' }} />
```
Default `timeOut: 3000`. Use `4000` for messages that need more reading time.
CSS class conventions:
- `e-toast-success` — successful operations
- `e-toast-danger` — errors
- `e-toast-warning` — non-critical issues or partial results
- `e-toast-info` — neutral informational messages
---
## 8. Form Fields
All form labels:
```jsx
<label style={{ display: 'block', marginBottom: 8, fontWeight: 500 }}>
Field label *
</label>
```
Help/hint text below a field:
```jsx
<div style={{ fontSize: '12px', color: '#666', marginTop: 4 }}>
Hint text here.
</div>
```
Empty state inside a card:
```jsx
<div style={{ fontSize: '14px', color: '#666' }}>Keine Einträge vorhanden.</div>
```
Vertical spacing between field groups: `marginBottom: 16`.
---
## 9. Tab Structure
Top-level and nested tabs use controlled `selectedItem` state with separate index variables per tab level.
This prevents sub-tab resets when parent state changes.
```jsx
const [academicTabIndex, setAcademicTabIndex] = React.useState(0);
<TabComponent
heightAdjustMode="Auto"
selectedItem={academicTabIndex}
selected={(e: TabSelectedEvent) => setAcademicTabIndex(e.selectedIndex ?? 0)}
>
<TabItemsDirective>
<TabItemDirective header={{ text: '🗂️ Perioden' }} content={AcademicPeriodsContent} />
<TabItemDirective header={{ text: '📥 Import & Liste' }} content={HolidaysImportAndListContent} />
</TabItemsDirective>
</TabComponent>
```
Tab header text uses an emoji prefix followed by a German label, consistent with all existing tabs.
Each nested tab level has its own separate index state variable.
---
## 10. Statistics Summary Cards
Used above grids and lists to show aggregate counts:
```jsx
<div style={{ marginBottom: 24, display: 'flex', gap: 16 }}>
<div className="e-card" style={{ flex: 1, padding: 16 }}>
<div style={{ fontSize: 14, color: '#6c757d', marginBottom: 4 }}>Label</div>
<div style={{ fontSize: 28, fontWeight: 600, color: '#28a745' }}>42</div>
</div>
</div>
```
---
## 11. Inline Warning Messages
For important warnings inside forms or dialogs:
```jsx
<div style={{
padding: 12,
backgroundColor: '#fff3cd',
border: '1px solid #ffc107',
borderRadius: 4,
marginBottom: 16,
fontSize: 14,
}}>
⚠️ Warning message text here.
</div>
```
For structured in-page errors or access-denied states, use `MessageComponent`:
```jsx
<MessageComponent severity="Error" content="Fehlermeldung" />
```
---
## 12. Color Palette
Only the following colors are used in status and UI elements across the dashboard.
Do not introduce new colors for new components.
| Use | Color |
|---|---|
| Success / active / online | `#28a745` |
| Danger / delete / offline | `#dc3545` |
| Warning / partial | `#f39c12` |
| Info / edit blue | `#0d6efd` |
| Neutral / archived / subtitle | `#6c757d` |
| Help / secondary text | `#666` |
| Inactive/muted | `#868e96` |
| Warning background | `#fff3cd` |
| Warning border | `#ffc107` |
---
## 13. Dedicated CSS Files
Use inline styles for settings tab sections and simpler pages.
Only create a dedicated `.css` file if the component requires complex layout, custom animations, or selector-based styles that are not feasible with inline styles.
Existing precedents: `monitoring.css`, `ressourcen.css`.
Do not use Tailwind — it has been removed from the project.
---
## 14. Loading States
For full-page loading, use a simple centered placeholder:
```jsx
<div style={{ padding: 24 }}>
<div style={{ textAlign: 'center', padding: 40 }}>Lade Daten...</div>
</div>
```
Do not use spinners or animated components unless a Syncfusion component provides them natively (e.g., busy state on `ButtonComponent`).
---
## 15. Locale and Language
All user-facing strings are in German.
Date formatting uses `toLocaleString('de-DE')` or `toLocaleTimeString('de-DE', { hour: '2-digit', minute: '2-digit' })`.
Never use English strings in labels, buttons, tooltips, or dialog headers visible to the end user.
**UTC time parsing**: The API returns ISO timestamps **without** a `Z` suffix (e.g., `"2025-11-27T20:03:00"`). Always append `Z` before constructing a `Date` to ensure correct UTC interpretation:
```tsx
const utcStr = dateStr.endsWith('Z') ? dateStr : dateStr + 'Z';
const date = new Date(utcStr);
```
When sending dates back to the API, use `date.toISOString()` (already UTC with `Z`).

- **Format**: Integer (group ID)
- **Purpose**: Assigns clients to groups
### TV Power Intent (Phase 1)
- **Topic**: `infoscreen/groups/{group_id}/power/intent`
- **QoS**: 1
- **Retained**: Yes
- **Format**: JSON object
- **Purpose**: Group-level desired power state for clients assigned to that group
Phase 1 is group-only. Per-client power intent topics and client state/ack topics are deferred to Phase 2.
Example payload:
```json
{
"schema_version": "tv-power-intent.v1",
"intent_id": "9cf26d9b-87a3-42f1-8446-e90bb6f6ce63",
"group_id": 12,
"desired_state": "on",
"reason": "active_event",
"issued_at": "2026-03-31T10:15:30Z",
"expires_at": "2026-03-31T10:17:00Z",
"poll_interval_sec": 30,
"source": "scheduler"
}
```
Contract notes:
- `intent_id` changes only on semantic transition (`desired_state`/`reason` changes).
- Heartbeat republishes keep `intent_id` stable while refreshing `issued_at` and `expires_at`.
- Expiry is poll-based: `max(3 x poll_interval_sec, 90)`.

- Dashboard: React + Vite + Syncfusion
- API: Flask + SQLAlchemy + Alembic
- DB: MariaDB
- Messaging: MQTT (Mosquitto)
- Background jobs: Redis + RQ + Gotenberg

```
- Dashboard talks only to API (`/api/...` via Vite proxy in dev).
- API is the single writer to MariaDB.
- Listener consumes MQTT discovery/heartbeat/log/screenshot topics and updates API state.
- Scheduler expands recurring events, applies exceptions, and publishes active content to retained MQTT topics.
- Worker handles document conversions asynchronously.
Data flow summary:
- Listener: consumes discovery and heartbeat messages from the MQTT Broker and updates the API Server (client registration/heartbeats).
- Listener screenshot flow: consumes `infoscreen/{uuid}/screenshot` and `infoscreen/{uuid}/dashboard`. Dashboard messages use grouped v2 schema (`message`, `content`, `runtime`, `metadata`); screenshot data is read from `content.screenshot`, capture type from `metadata.capture.type`, and forwarded to `POST /api/clients/{uuid}/screenshot`.
- Scheduler: reads events from the API Server and publishes only currently active content to the MQTT Broker (retained topics per group). When a group has no active events, the scheduler clears its retained topic by publishing an empty list. All time comparisons are done in UTC; any naive timestamps are normalized.
- Clients: send discovery/heartbeat via the MQTT Broker (handled by the Listener) and receive content from the Scheduler via MQTT.
- Worker: receives conversion commands directly from the API Server and reports results/status back to the API (no MQTT involved).
- MariaDB: is accessed exclusively by the API Server. The Dashboard never talks to the database directly; it only communicates with the API.
## 🌟 Key Features
- **User Management**: Comprehensive role-based access control (user → editor → admin → superadmin)
- Admin panel for user CRUD operations with audit tracking
- Self-service password change available to all users
- Audit trail: login times, password changes, deactivation history
- Soft-delete by default, hard-delete superadmin-only
- Modern React-based web interface with Syncfusion components
- Real-time client monitoring and group management
- Event scheduling with academic period support
- Media management with presentation conversion
- Holiday calendar integration
- Visual indicators: TentTree icon next to the main event icon marks events that skip holidays (icon color: black)
- **Event Deletion**: All event types (single, single-in-series, entire series) are handled with custom dialogs. The frontend intercepts Syncfusion's built-in RecurrenceAlert and DeleteAlert popups to provide a unified, user-friendly deletion flow:
- Single (non-recurring) event: deleted directly after confirmation.
- Single occurrence of a recurring series: user can delete just that instance.
- Entire recurring series: user can delete all occurrences after a final custom confirmation dialog.
- Detached occurrences (edited/broken out): treated as single events.
### 🎯 **Event System**
- **Presentations**: PowerPoint/LibreOffice → PDF conversion via Gotenberg
- **Websites**: URL-based content display
- **Videos**: Media file streaming with per-event playback settings (`autoplay`, `loop`, `volume`, `muted`); system-wide defaults configurable under Settings → Events → Videos
- **Messages**: Text announcements
- **WebUntis**: Educational schedule integration
- Uses the system-wide Vertretungsplan/Supplement-Table URL (`supplement_table_url`) configured under Settings → Events. No separate per-event URL is required; WebUntis events display the same as Website events.
- **Recurrence & Holidays**: Recurring events can be configured to skip holidays. The backend generates EXDATEs (RecurrenceException) for holiday occurrences using RFC 5545 timestamps (yyyyMMddTHHmmssZ), so the calendar never shows those instances. The scheduler queries a 7-day window to expand recurring events and applies event exceptions, but only publishes events that are active at the current time (UTC). The "Termine an Ferientagen erlauben" toggle does not affect these events.
- **Single Occurrence Editing**: Users can edit individual occurrences of recurring events without affecting the master series. The system provides a confirmation dialog to choose between editing a single occurrence or the entire series.
### 🏫 **Academic Period Management**
- Support for school years, semesters, and trimesters
- Austrian school system integration
- Holiday calendar synchronization
- Period-based event organization
### 📡 **Real-time Communication**
- MQTT-based client discovery and heartbeat monitoring
- Retained topics for reliable state synchronization
- WebSocket support for browser clients
- Automatic client group assignment
### 🔄 **Background Processing**
- Redis-based job queues for presentation conversion
- Gotenberg integration for LibreOffice/PowerPoint processing
- Asynchronous file processing with status tracking
- RQ (Redis Queue) worker management

## 🛠️ Services
### 🖥️ **Dashboard** (`dashboard/`)
- **Technology**: React 19 + TypeScript + Vite
- **UI Framework**: Syncfusion components (Material 3 theme)
- **Styling**: Centralized Syncfusion Material 3 CSS imports in `dashboard/src/main.tsx`
- **Features**: Responsive design, real-time updates, file management
- **Port**: 5173 (dev), served via Nginx (prod)
- **Data access**: No direct database connection; communicates with the API Server only via HTTP.
- **Dev proxy tip**: In development, use relative paths like `/api/...` in the frontend to route through Vite's proxy to the API. Avoid absolute URLs with an extra `/api` segment to prevent CORS or double-path issues.
### 🔧 **API Server** (`server/`)
- **Technology**: Flask + SQLAlchemy + Alembic
- **Database**: MariaDB with timezone-aware timestamps
- **Features**: RESTful API, file uploads, MQTT integration
- Recurrence/holidays: returns only master events with `RecurrenceRule` and `RecurrenceException` (EXDATEs) so clients render recurrences and skip holiday instances reliably.
- Recurring events are only deactivated after their recurrence_end (UNTIL); non-recurring events deactivate after their end time. Event exceptions are respected and rendered in scheduler output.
- Single occurrence detach: `POST /api/events/<id>/occurrences/<date>/detach` creates standalone events from recurring series without modifying the master event.
- **Port**: 8000
- **Health Check**: `/health`
### 👂 **Listener** (`listener/`)
### ⏰ **Scheduler** (`scheduler/`)
**Technology**: Python + SQLAlchemy
**Purpose**: Event publishing, group-based content distribution
**Features**:
- Queries a future window (default: 7 days) to expand recurring events
- Expands recurrences using RFC 5545 rules
- Applies event exceptions (skipped dates, detached occurrences)
- Only deactivates recurring events after their recurrence_end (UNTIL)
- Publishes only currently active events to MQTT (per group)
- Clears retained topics by publishing an empty list when a group has no active events
- Normalizes naive timestamps and compares times in UTC
- Logging is concise; conversion lookups are cached and logged only once per media
### 🔄 **Worker** (Conversion Service)
- **Technology**: RQ (Redis Queue) + Gotenberg
- **Purpose**: Background presentation conversion
- **Features**: PPT/PPTX/ODP → PDF conversion, status tracking
### 🗄️ **Database** (MariaDB 11.2)
- **Features**: Health checks, automatic initialization
- **Migrations**: Alembic-based schema management
- **Timezone**: UTC-aware timestamps
### 📡 **MQTT Broker** (Eclipse Mosquitto 2.0.21)
- **Features**: WebSocket support, health monitoring
- **Topics**:
- `infoscreen/discovery` - Client registration
- `infoscreen/{uuid}/heartbeat` - Client alive status
- `infoscreen/events/{group_id}` - Event distribution
## 🔗 Scheduler Event Payloads
- Presentations include a `presentation` object with `files`, `slide_interval`, `page_progress`, and `auto_progress`.
- Website and WebUntis events share a unified payload:
- `website`: `{ "type": "browser", "url": "https://..." }`
- The `event_type` field remains specific (e.g., `presentation`, `website`, `webuntis`) so clients can dispatch appropriately; however, `website` and `webuntis` should be handled identically in clients.
- Videos include a `video` payload with a stream URL and playback flags:
- `video`: includes `url` (streaming endpoint) and `autoplay`, `loop`, `volume`, `muted`
- Streaming endpoint supports byte-range requests (206) to enable seeking: `/api/eventmedia/stream/<media_id>/<filename>`
- Server-side UTC: All backend comparisons are performed in UTC; API returns ISO strings without `Z`. Frontend appends `Z` before parsing.
## Recent changes since last commit
- Monitoring system: End-to-end monitoring is now implemented. The listener ingests `logs/*` and `health` MQTT topics, the API exposes monitoring endpoints (`/api/client-logs/monitoring-overview`, `/api/client-logs/recent-errors`, `/api/client-logs/<uuid>/logs`), and the superadmin dashboard page shows live client status, screenshots, and recent errors.
- Screenshot priority flow: Screenshot payloads now support `screenshot_type` (`periodic`, `event_start`, `event_stop`). `event_start` and `event_stop` are treated as high-priority screenshots; the API stores typed screenshots, maintains priority metadata, and serves active priority screenshots through `/screenshots/{uuid}/priority`.
- MQTT dashboard payload v2 cutover: Listener parsing is now v2-only for dashboard JSON payloads (`message/content/runtime/metadata`). Legacy top-level dashboard fallback has been removed after migration completion; parser observability tracks `v2_success` and `parse_failures`.
- Presentation persistence fix: Fixed persistence of presentation flags so `page_progress` and `auto_progress` are reliably stored and returned for create/update flows and detached occurrences.
- Additional improvements: Video/streaming, scheduler metadata, settings defaults, and UI refinements remain documented in the detailed sections below.
These changes are designed to be safe if metadata extraction or probes fail — clients should still attempt playback using the provided `url` and fall back to requesting/resolving richer metadata when available.
See `MQTT_EVENT_PAYLOAD_GUIDE.md` for details.
## 🧩 Developer Environment Notes (Dev Container)
- Extensions: UI-only `Dev Containers` runs on the host UI; not installed inside the container to avoid reinstallation loops. See `/.devcontainer/devcontainer.json` (`remote.extensionKind`).
- Installs: Dashboard uses `npm ci` on `postCreateCommand` for reproducible installs.
- Aliases: `postStartCommand` appends shell aliases idempotently to prevent duplicates across restarts.
## 📦 Versioning
- Unified app version: Use a single SemVer for the product (e.g., `2025.1.0-beta.3`) — simplest for users and release management.
- Pre-releases: Use identifiers like `-alpha.N`, `-beta.N`, `-rc.N` for stage tracking.
- Build metadata: Optionally include component build info (non-ordering) e.g., `+api.abcd123,dash.efgh456,sch.jkl789,wkr.mno012`.
- Component traceability: Document component SHAs or image tags under each TECH-CHANGELOG release entry rather than exposing separate user-facing versions.
- Hotfixes: For backend-only fixes, prefer a patch bump or pre-release increment, and record component metadata under the unified version.

## 🎨 Frontend Features
### API Response Format
- **JSON Convention**: All API endpoints return camelCase JSON (e.g., `startTime`, `endTime`, `groupId`). Frontend consumes camelCase directly.
- **UTC Time Parsing**: API returns ISO strings without 'Z' suffix. Frontend appends 'Z' before parsing to ensure UTC interpretation: `const utcString = dateStr.endsWith('Z') ? dateStr : dateStr + 'Z'; new Date(utcString);`. Display uses `toLocaleTimeString('de-DE')` for German format.
### Recurrence & holidays
- Recurrence is handled natively by Syncfusion. The API returns master events with `RecurrenceRule` and `RecurrenceException` (EXDATE) in RFC 5545 format (yyyyMMddTHHmmssZ, UTC) so the Scheduler excludes holiday instances reliably.
- Events with "skip holidays" display a TentTree icon next to the main event icon (icon color: black). The Scheduler’s native lower-right recurrence badge indicates series membership.
- Single occurrence editing: Users can edit either a single occurrence or the entire series. The UI persists changes using `onActionCompleted (requestType='eventChanged')`:
- Single occurrence → `POST /api/events/<id>/occurrences/<date>/detach` (creates standalone event and adds EXDATE to master)
- Series/single event → `PUT /api/events/<id>`
### Syncfusion Components Used (Material 3)
- **Schedule**: Event calendar with drag-drop support
- **Grid**: Data tables with filtering and sorting
- **DropDownList**: Group and period selectors
- **FileManager**: Media upload and organization
- **Kanban**: Task management views
- **Notifications**: Toast messages and alerts
- **Pager**: Used on Programinfo changelog for pagination
- **Cards (layouts)**: Programinfo sections styled with Syncfusion card classes

- **SSL/TLS**: HTTPS support with custom certificates
- **MQTT Security**: Username/password authentication
- **Database**: Parameterized queries, connection pooling
- **File Uploads**: Type validation, size limits
- **CORS**: Configured for production deployment
## 📊 Monitoring & Logging
### Health Checks
- Database: Connection and initialization status
- MQTT: Pub/sub functionality test
- Dashboard: Nginx availability
- **Scheduler**: Logging is concise; conversion lookups are cached and logged only once per media.
- Monitoring API: `/api/client-logs/monitoring-overview` and `/api/client-logs/recent-errors` for live diagnostics
- Monitoring overview includes screenshot priority state (`latestScreenshotType`, `priorityScreenshotType`, `priorityScreenshotReceivedAt`, `hasActivePriorityScreenshot`) and `summary.activePriorityScreenshots`
### Logging Strategy
- **Development**: Docker Compose logs with service prefixes
- **Production**: Centralized logging via Docker log drivers
- **MQTT**: Message-level debugging available
- **Database**: Query logging in development mode
## 🌍 Deployment Options
### Development
- **Hot Reload**: Vite dev server + Flask debug mode
- **Volume Mounts**: Live code editing
- **Debug Ports**: Python debugger support (port 5678)
- **Local Certificates**: Self-signed SSL for testing
### Production
- **Optimized Builds**: Multi-stage Dockerfiles
- **Reverse Proxy**: Nginx with SSL termination
- **Health Monitoring**: Comprehensive healthchecks
- **Registry**: GitHub Container Registry integration
- **Scaling**: Docker Compose for single-node deployment

- MQTT: localhost:1883 (WS: 9001)
## Holiday Calendar (Quick Usage)
Settings path:
- `Settings` -> `Academic Calendar` -> `Ferienkalender: Import/Anzeige`
Workflow summary:
1. Select target academic period (archived periods are read-only/not selectable).
2. Import CSV/TXT or add/edit holidays manually.
3. Validation is period-scoped (out-of-period ranges are blocked).
4. Duplicate/overlap policy:
- exact duplicates: skipped/prevented
- same normalized `name+region` overlaps (including adjacent ranges): merged
- different-identity overlaps: conflict (manual blocked, import skipped with details)
5. Recurring events with `skip_holidays` are recalculated automatically after holiday changes.

## Scheduler Runtime Flags
# Check credentials in .env file
# Restart dependent services
Scheduler runtime defaults can be tuned with environment variables:
- `POLL_INTERVAL_SECONDS` (default: `30`)
- `REFRESH_SECONDS` (default: `0`, disabled)
TV power coordination (server Phase 1, group-level intent only):
- `POWER_INTENT_PUBLISH_ENABLED` (default: `false`)
- `POWER_INTENT_HEARTBEAT_ENABLED` (default: `true`)
- `POWER_INTENT_EXPIRY_MULTIPLIER` (default: `3`)
- `POWER_INTENT_MIN_EXPIRY_SECONDS` (default: `90`)
Power intent topic contract for Phase 1:
- Topic: `infoscreen/groups/{group_id}/power/intent`
- QoS: `1`
- Retained: `true`
- Publish mode: transition publish + heartbeat republish each poll
- Schema version: `v1`
- Intent ID behavior: stable across unchanged heartbeat cycles; new UUID only on semantic transition (desired_state or reason change)
- Expiry rule: max(3 × poll_interval, 90 seconds)
Rollout strategy (Phase 1):
1. Keep `POWER_INTENT_PUBLISH_ENABLED=false` by default (disabled).
2. Enable in test environment first: set `POWER_INTENT_PUBLISH_ENABLED=true` on one canary group's scheduler instance.
3. Verify no unintended OFF between adjacent/overlapping events over 1–2 days.
4. Expand to 20% of production groups for 2 days (canary soak).
5. Monitor power-intent publish metrics (success rate, error rate, transition frequency) in scheduler logs.
6. Roll out to 100% once canary is stable (zero off-between-adjacent-events incidents).
7. Phase 2 (future): per-client override intents and state acknowledgments.

## 🧭 Changelog Style Guide
When adding entries to `dashboard/public/program-info.json` (displayed on the Program info page):
- Structure per release
- `version` (e.g., `2025.1.0-alpha.8`)
- `date` in `YYYY-MM-DD` (ISO format)
- `changes`: array of short bullet strings
- Categories (Keep a Changelog inspired)
- Prefer starting bullets with an implicit category or an emoji, e.g.:
- Added (🆕/✨), Changed (🔧/🛠️), Fixed (🐛/✅), Removed (🗑️), Security (🔒), Deprecated (⚠️)
- Writing rules
- Keep bullets concise (ideally one line) and user-facing; avoid internal IDs or jargon
- Put the affected area first when helpful (e.g., “UI: …”, “API: …”, “Scheduler: …”)
- Highlight breaking changes with “BREAKING:”
- Prefer German wording consistently; dates are localized at runtime for display
- Ordering and size
- Newest release first in the array
- Aim for ≤ 8–10 bullets per release; group or summarize if longer
- JSON hygiene
- Valid JSON only (no trailing commas); escape quotes as needed
- One release object per version; do not modify historical entries unless to correct typos
The Program info page paginates older entries (default page size 5). Keep highlights at the top of each release for scanability.

## 2026.1.0-alpha.15 (2026-03-31)
- 🗃️ **Holiday data model scoping to academic periods**:
- Added period scoping for holidays via `SchoolHoliday.academic_period_id` (FK to academic periods) in `models/models.py`.
- Added Alembic migration `f3c4d5e6a7b8_scope_school_holidays_to_academic_.py` to introduce FK/index/constraint updates for period-aware holiday storage.
- Updated uniqueness semantics and indexing so holiday identity is evaluated in the selected academic period context.
- 🔌 **Holiday API hardening (`server/routes/holidays.py`)**:
- Extended to period-scoped workflows for list/import/manual CRUD.
- Added manual CRUD endpoints and behavior:
- `POST /api/holidays`
- `PUT /api/holidays/<id>`
- `DELETE /api/holidays/<id>`
- Enforced date-range validation against selected academic period for both import and manual writes.
- Added duplicate prevention (normalized name/region matching with null-safe handling).
- Implemented overlap policy:
- Same normalized `name+region` overlaps (including adjacent ranges) are merged.
- Different-identity overlaps are treated as conflicts (manual blocked, import skipped with details).
- Import responses now include richer counters/details (inserted/updated/merged/skipped/conflicts).
- 🔁 **Recurrence integration updates**:
- Event holiday-skip exception regeneration now resolves holidays by `academic_period_id` instead of global holiday sets.
- Updated event-side recurrence handling (`server/routes/events.py`) to keep EXDATE behavior in sync with period-scoped holidays.
- 🖥️ **Frontend integration (technical)**:
- Updated holiday API client (`dashboard/src/apiHolidays.ts`) for period-aware list/upload and manual CRUD operations.
- Settings holiday management (`dashboard/src/settings.tsx`) now binds import/list/manual CRUD to selected academic period and surfaces conflict/merge outcomes.
- Dashboard and appointments holiday data loading updated to active-period context.
- 📖 **Documentation & release alignment**:
- Updated `.github/copilot-instructions.md` with period-scoped holiday conventions, overlap policy, and settings behavior.
- Refactored root `README.md` to index-style documentation and archived historical implementation docs under `docs/archive/`.
- Synchronized release line with user-facing version `2026.1.0-alpha.15` in `dashboard/public/program-info.json`.
Notes for integrators:
- Holiday operations now require a clear academic period context; archived periods should be treated as read-only for holiday mutation flows.
- Existing recurrence flows depend on period-scoped holiday sets; verify period assignment for recurring master events when validating skip-holidays behavior.
## 2026.1.0-alpha.14 (2026-01-28)
- 🗓️ **Ressourcen Page (Timeline View)**:
- New frontend page: `dashboard/src/ressourcen.tsx` (357 lines) – Parallel timeline view showing active events for all room groups

# TV Power Coordination Canary Validation Checklist (Phase 1)
Manual verification checklist for Phase-1 server-side group-level power-intent publishing before production rollout.
## Preconditions
- Scheduler running with `POWER_INTENT_PUBLISH_ENABLED=true`
- One canary group selected for testing (example: group_id=1)
- Mosquitto broker running and accessible
- Database with seeded test data (canary group with events)
## Validation Scenarios
### 1. Baseline Payload Structure
**Goal**: Retained topic shows correct Phase-1 contract.
Instructions:
1. Subscribe to `infoscreen/groups/1/power/intent` (canary group, QoS 1)
2. Verify received payload contains:
- `schema_version: "v1"`
- `group_id: 1`
- `desired_state: "on"` or `"off"` (string)
- `reason: "active_event"` or `"no_active_event"` (string)
- `intent_id: "<uuid>"` (not empty, valid UUID v4 format)
- `issued_at: "2026-03-31T14:22:15Z"` (ISO 8601 with Z suffix)
- `expires_at: "2026-03-31T14:24:00Z"` (ISO 8601 with Z suffix, always > issued_at)
- `poll_interval_sec: 30` (integer, matches scheduler poll interval)
**Pass criteria**: All fields present, correct types and formats, no extra/malformed fields.
### 2. Event Start Transition
**Goal**: ON intent published immediately when event becomes active.
Instructions:
1. Create an event for canary group starting 2 minutes from now
2. Wait for event start time
3. Check retained topic immediately after event start
4. Verify `desired_state: "on"` and `reason: "active_event"`
5. Note the `intent_id` value
**Pass criteria**:
- `desired_state: "on"` appears within 30 seconds of event start
- No OFF in between (if a prior OFF existed)
### 3. Event End Transition
**Goal**: OFF intent published when last active event ends.
Instructions:
1. In setup from Scenario 2, wait for the event to end (< 5 min duration)
2. Check retained topic after end time
3. Verify `desired_state: "off"` and `reason: "no_active_event"`
**Pass criteria**:
- `desired_state: "off"` appears within 30 seconds of event end
- New `intent_id` generated (different from Scenario 2)
### 4. Adjacent Events (No OFF Blip)
**Goal**: When one event ends and next starts immediately after, no OFF is published.
Instructions:
1. Create two consecutive events for canary group, each 3 minutes:
- Event A: 14:00-14:03
- Event B: 14:03-14:06
2. Watch retained topic through both event boundaries
3. Capture all `desired_state` changes
**Pass criteria**:
- `desired_state: "on"` throughout both events
- No OFF at 14:03 (boundary between them)
- One or two transitions total (transition at A start only, or at A start + semantic change reasons)
### 5. Heartbeat Republish (Unchanged Intent)
**Goal**: Intent republishes each poll cycle with same intent_id if state unchanged.
Instructions:
1. Create a long-duration event (15+ minutes) for canary group
2. Subscribe to power intent topic
3. Capture timestamps and intent_ids for 3 consecutive poll cycles (90 seconds with default 30s polls)
4. Verify:
- Payload received at T, T+30s, T+60s
- Same `intent_id` across all three
- Different `issued_at` timestamps (should increment by ~30s)
**Pass criteria**:
- At least 3 payloads received within ~90 seconds
- Same `intent_id` for all
- Each `issued_at` is later than previous
- Each `expires_at` is 90 seconds after its `issued_at`
### 6. Scheduler Restart (Immediate Republish)
**Goal**: On scheduler process start, immediate published active intent.
Instructions:
1. Create and start an event for canary group (duration ≥ 5 minutes)
2. Wait for event to be active
3. Kill and restart scheduler process
4. Check retained topic within 5 seconds after restart
5. Verify `desired_state: "on"` and `reason: "active_event"`
**Pass criteria**:
- Correct ON intent retained within 5 seconds of restart
- No OFF published during restart/reconnect
### 7. Broker Reconnection (Retained Recovery)
**Goal**: On MQTT reconnect, scheduler republishes cached intents.
Instructions:
1. Create and start an event for canary group
2. Subscribe to power intent topic
3. Note the current `intent_id` and payload
4. Restart Mosquitto broker (simulates network interruption)
5. Verify retained topic is immediately republished after reconnect
**Pass criteria**:
- Correct ON intent reappears on retained topic within 5 seconds of broker restart
- Same `intent_id` (no new transition UUID)
- Publish metrics show `retained_republish_total` incremented
### 8. Feature Flag Disable
**Goal**: No power-intent publishes when feature disabled.
Instructions:
1. Set `POWER_INTENT_PUBLISH_ENABLED=false` in scheduler env
2. Restart scheduler
3. Create and start a new event for canary group
4. Subscribe to power intent topic
5. Wait 90 seconds
**Pass criteria**:
- No messages on `infoscreen/groups/1/power/intent`
- Scheduler logs show no `event=power_intent_publish*` lines
### 9. Scheduler Logs Inspection
**Goal**: Logs contain structured fields for observability.
Instructions:
1. Run canary with one active event
2. Collect scheduler logs for 60 seconds
3. Filter for `event=power_intent_publish` lines
**Pass criteria**:
- Each log line contains: `group_id`, `desired_state`, `reason`, `intent_id`, `issued_at`, `expires_at`, `transition_publish`, `heartbeat_publish`, `topic`, `qos`, `retained`
- No malformed JSON in payloads
- Error logs (if any) are specific and actionable
### 10. Expiry Validation
**Goal**: Payloads never published with `expires_at <= issued_at`.
Instructions:
1. Capture power-intent payloads for 120+ seconds
2. Parse `issued_at` and `expires_at` for each
3. Verify `expires_at > issued_at` for all
**Pass criteria**:
- All 100% of payloads have valid expiry window
- Typical delta is 90 seconds (min expiry)

# TV Power Coordination Task List (Server + Client)
## Goal
Prevent unintended TV power-off during adjacent events while enabling coordinated, server-driven power intent via MQTT with robust client-side fallback.
## Scope
- Server publishes explicit TV power intent and event-window context.
- Client executes HDMI-CEC power actions with timer-safe behavior.
- Client falls back to local schedule/end-time logic if server intent is missing or stale.
- Existing event playback behavior remains backward compatible.
## Ownership Proposal
- Server team: Scheduler integration, power-intent publisher, reliability semantics.
- Client team: MQTT handler, state machine, CEC execution, fallback and observability.
## Server PR-1 Pointer
- For the strict, agreed server-first implementation path, use:
- `TV_POWER_SERVER_PR1_IMPLEMENTATION_CHECKLIST.md`
- Treat that checklist as the execution source of truth for Phase 1.
---
## 1. MQTT Contract (Shared Spec)
Phase-1 scope note:
- Group-level power intent is the only active server contract in Phase 1.
- Per-client power intent and client power state topics are deferred to Phase 2.
### 1.1 Topics
- Command/intent topic (retained):
- infoscreen/groups/{group_id}/power/intent
Phase-2 (deferred):
- Optional per-client command/intent topic (retained):
- infoscreen/{client_id}/power/intent
- Client state/ack topic:
- infoscreen/{client_id}/power/state
### 1.2 QoS and retain
- intent topics: QoS 1, retained=true
- state topic: QoS 0 or 1 (recommend QoS 0 initially), retained=false (Phase 2)
### 1.3 Intent payload schema (v1)
```json
{
"schema_version": "1.0",
"intent_id": "uuid-or-monotonic-id",
"group_id": 12,
"desired_state": "on",
"reason": "active_event",
"issued_at": "2026-03-31T12:00:00Z",
"expires_at": "2026-03-31T12:01:30Z",
"poll_interval_sec": 15,
"event_window_start": "2026-03-31T12:00:00Z",
"event_window_end": "2026-03-31T13:00:00Z",
"source": "scheduler"
}
```
### 1.4 State payload schema (client -> server)
Phase-2 (deferred).
```json
{
"schema_version": "1.0",
"intent_id": "last-applied-intent-id",
"client_id": "...",
"reported_at": "2026-03-31T12:00:01Z",
"power": {
"applied_state": "on",
"source": "mqtt_intent|local_fallback",
"result": "ok|skipped|error",
"detail": "free text"
}
}
```
### 1.5 Idempotency and ordering rules
- Client applies only newest valid intent by issued_at then intent_id tie-break.
- Duplicate intent_id must be ignored after first successful apply.
- Expired intents must not trigger new actions.
- Retained intent must be immediately usable after client reconnect.
### 1.6 Safety rules
- desired_state=on cancels any pending delayed-off timer before action.
- desired_state=off may schedule delayed-off, never immediate off during an active event window.
- If payload is malformed, client logs and ignores it.
---
## 2. Server Team Task List
### 2.1 Contract + scheduler mapping
- Finalize field names and UTC timestamp format with client team.
- Define when scheduler emits on/off intents for adjacent/overlapping events.
- Ensure contiguous events produce uninterrupted desired_state=on coverage.
### 2.2 Publisher implementation
- Add publisher for infoscreen/groups/{group_id}/power/intent.
- Support retained messages and QoS 1.
- Include expires_at based on scheduler poll interval (`max(3 x poll, 90s)`).
- Emit new intent_id only for semantic state transitions.
### 2.3 Reconnect and replay behavior
- On scheduler restart, republish current effective intent as retained.
- On event edits/cancellations, publish replacement retained intent.
### 2.4 Conflict policy
- Phase 1: not applicable (group-only intent).
- Phase 2: define precedence when both group and per-client intents exist.
- Recommended for Phase 2: per-client overrides group intent.
### 2.5 Monitoring and diagnostics
- Record publish attempts, broker ack results, and active retained payload.
- Add operational dashboard panels for intent age and last transition.
### 2.6 Server acceptance criteria
- Adjacent event windows do not produce off intent between events.
- Reconnect test: fresh client receives retained intent and powers correctly.
- Expired intent is never acted on by a conforming client.
---
## 3. Client Team Task List
### 3.1 MQTT subscription + parsing
- Phase 1: Subscribe to infoscreen/groups/{group_id}/power/intent.
- Phase 2 (optional): Subscribe to infoscreen/{client_id}/power/intent for per-device overrides.
- Parse schema_version=1.0 payload with strict validation.
### 3.2 Power state controller integration
- Add power-intent handler in display manager path that owns HDMI-CEC decisions.
- On desired_state=on:
- cancel delayed-off timer
- call CEC on only if needed
- On desired_state=off:
- schedule delayed off using configured grace_seconds (or local default)
- re-check active event before executing off
### 3.3 Fallback behavior (critical)
- If MQTT unreachable, intent missing, invalid, or expired:
- fall back to existing local event-time logic
- use event end as off trigger with existing delayed-off safety
- If local logic sees active event, enforce cancel of pending off timer.
### 3.4 Adjacent-event race hardening
- Guarantee pending off timer is canceled on any newly active event.
- Ensure event switch path never requests off while next event is active.
- Add explicit logging for timer create/cancel/fire with reason and event_id.
### 3.5 State publishing
- Publish apply results to infoscreen/{client_id}/power/state.
- Include source=mqtt_intent or local_fallback.
- Include last intent_id and result details for troubleshooting.
### 3.6 Config flags
- Add feature toggle:
- POWER_CONTROL_MODE=local|mqtt|hybrid (recommend default: hybrid)
- hybrid behavior:
- prefer valid mqtt intent
- automatically fall back to local logic
### 3.7 Client acceptance criteria
- Adjacent events: no unintended off between two active windows.
- Broker outage during event: TV remains on via local fallback.
- Broker recovery: retained intent reconciles state without oscillation.
- Duplicate/old intents do not cause repeated CEC toggles.
---
## 4. Integration Test Matrix (Joint)
## 4.1 Happy paths
- Single event start -> on intent -> TV on.
- Event end -> off intent -> delayed off -> TV off.
- Adjacent events (end==start or small gap) -> uninterrupted TV on.
## 4.2 Failure paths
- Broker down before event start.
- Broker down during active event.
- Malformed retained intent at reconnect.
- Delayed off armed, then new event starts before timer fires.
## 4.3 Consistency checks
- Client state topic reflects actual applied source and result.
- Logs include intent_id correlation across server and client.
---
## 5. Rollout Plan
### Phase 1: Contract and feature flags
- Freeze schema and topic naming for group-only intent.
- Ship client support behind POWER_CONTROL_MODE=hybrid.
### Phase 2: Server publisher rollout
- Enable publishing for test group only.
- Verify retained and reconnect behavior.
### Phase 3: Production enablement
- Enable hybrid mode fleet-wide.
- Observe for 1 week: off-between-adjacent-events incidents must be zero.
### Phase 4: Optional tightening
- If metrics are stable, evaluate mqtt-first policy while retaining local safety fallback.
---
## 6. Definition of Done
- Shared MQTT contract approved by both teams.
- Server and client implementations merged with tests.
- Adjacent-event regression test added and passing.
- Operational runbook updated (topics, payloads, fallback behavior, troubleshooting).
- Production monitoring confirms no unintended mid-schedule TV power-off.

# Server Handoff: TV Power Coordination
## Purpose
Implement server-side MQTT power intent publishing so clients can keep TVs on across adjacent events and power off safely after schedules end.
## Source of Truth
- Shared full plan: TV_POWER_COORDINATION_TASKLIST.md
## Scope (Server Team)
- Scheduler-to-intent mapping
- MQTT publishing semantics (retain, QoS, expiry)
- Conflict handling (group vs client)
- Observability for intent lifecycle
## MQTT Contract (Server Responsibilities)
### Topics
- Primary (per-client): infoscreen/{client_id}/power/intent
- Optional (group-level): infoscreen/groups/{group_id}/power/intent
### Delivery Semantics
- QoS: 1
- retained: true
- Always publish UTC timestamps (ISO 8601 with Z)
### Intent Payload (v1)
```json
{
"schema_version": "1.0",
"intent_id": "uuid-or-monotonic-id",
"issued_at": "2026-03-31T12:00:00Z",
"expires_at": "2026-03-31T12:10:00Z",
"target": {
"client_id": "optional-if-group-topic",
"group_id": "optional"
},
"power": {
"desired_state": "on",
"reason": "event_window_active",
"grace_seconds": 30
},
"event_window": {
"start": "2026-03-31T12:00:00Z",
"end": "2026-03-31T13:00:00Z"
}
}
```
## Required Behavior
### Adjacent/Overlapping Events
- Never publish an intermediate off intent when windows are contiguous/overlapping.
- Maintain continuous desired_state=on coverage across adjacent windows.
### Reconnect/Restart
- On scheduler restart, republish effective retained intent.
- On event edits/cancellations, replace retained intent with a fresh intent_id.
### Conflict Policy
- If both group and client intent exist: per-client overrides group.
### Expiry Safety
- expires_at must be set for every intent.
- Server should avoid publishing already-expired intents.
## Implementation Tasks
1. Add scheduler mapping layer that computes effective desired_state per client timeline.
2. Add intent publisher with retained QoS1 delivery.
3. Generate unique intent_id for each semantic transition.
4. Emit issued_at/expires_at and event_window consistently in UTC.
5. Add group-vs-client precedence logic.
6. Add logs/metrics for publish success, retained payload age, and transition count.
7. Add integration tests for adjacent events and reconnect replay.
## Acceptance Criteria
1. Adjacent events do not create OFF gap intents.
2. Fresh client receives retained intent after reconnect and gets correct desired state.
3. Intent payloads are schema-valid, UTC-formatted, and include expiry.
4. Publish logs and metrics allow intent timeline reconstruction.
## Operational Notes
- Keep intent publishing idempotent and deterministic.
- Preserve backward compatibility while clients run in hybrid mode.

# TV Power Intent — Server Contract v1 (Phase 1)
> This document is the stable reference for client-side implementation.
> The server implementation is validated and frozen at this contract.
> Last validated: 2026-04-01
---
## Topic
```
infoscreen/groups/{group_id}/power/intent
```
- **Scope**: group-level only (Phase 1). No per-client topic in Phase 1.
- **QoS**: 1
- **Retained**: true — broker holds last payload; client receives it immediately on (re)connect.
---
## Publish semantics
| Trigger | Behaviour |
|---|---|
| Semantic transition (state/reason changes) | New `intent_id`, immediate publish |
| No change (heartbeat) | Same `intent_id`, refreshed `issued_at` and `expires_at`, published every poll interval |
| Scheduler startup | Immediate publish before first poll wait |
| MQTT reconnect | Immediate retained republish of last known intent |
Poll interval default: **15 seconds** (dev) / **30 seconds** (prod).
---
## Payload schema
All fields are always present. No optional fields for Phase 1 required fields.
```json
{
"schema_version": "1.0",
"intent_id": "<uuid4>",
"group_id": <integer>,
"desired_state": "on" | "off",
"reason": "active_event" | "no_active_event",
"issued_at": "<ISO 8601 UTC with Z>",
"expires_at": "<ISO 8601 UTC with Z>",
"poll_interval_sec": <integer>,
"active_event_ids": [<integer>, ...],
"event_window_start": "<ISO 8601 UTC with Z>" | null,
"event_window_end": "<ISO 8601 UTC with Z>" | null
}
```
### Field reference
| Field | Type | Description |
|---|---|---|
| `schema_version` | string | Always `"1.0"` in Phase 1 |
| `intent_id` | string (uuid4) | Stable across heartbeats; new value on semantic transition |
| `group_id` | integer | Matches the MQTT topic group_id |
| `desired_state` | `"on"` or `"off"` | The commanded TV power state |
| `reason` | string | Human-readable reason for current state |
| `issued_at` | UTC Z string | When this payload was computed |
| `expires_at` | UTC Z string | After this time, payload is stale; re-subscribe or treat as `off` |
| `poll_interval_sec` | integer | Server poll interval; expiry = max(3 × poll, 90s) |
| `active_event_ids` | integer array | IDs of currently active events; empty when `off` |
| `event_window_start` | UTC Z string or null | Start of merged active coverage window; null when `off` |
| `event_window_end` | UTC Z string or null | End of merged active coverage window; null when `off` |
---
## Expiry rule
```
expires_at = issued_at + max(3 × poll_interval_sec, 90s)
```
Default at poll=15s → expiry window = **90 seconds**.
**Client rule**: if `now > expires_at` treat as stale and fall back to `off` until a fresh payload arrives.
---
## Example payloads
### ON (active event)
```json
{
"schema_version": "1.0",
"intent_id": "4a7fe3bc-3654-48e3-b5b9-9fad1f7fead3",
"group_id": 2,
"desired_state": "on",
"reason": "active_event",
"issued_at": "2026-04-01T06:00:03.496Z",
"expires_at": "2026-04-01T06:01:33.496Z",
"poll_interval_sec": 15,
"active_event_ids": [148],
"event_window_start": "2026-04-01T06:00:00Z",
"event_window_end": "2026-04-01T07:00:00Z"
}
```
### OFF (no active event)
```json
{
"schema_version": "1.0",
"intent_id": "833c53e3-d728-4604-9861-6ff7be1f227e",
"group_id": 2,
"desired_state": "off",
"reason": "no_active_event",
"issued_at": "2026-04-01T07:00:03.702Z",
"expires_at": "2026-04-01T07:01:33.702Z",
"poll_interval_sec": 15,
"active_event_ids": [],
"event_window_start": null,
"event_window_end": null
}
```
---
## Validated server behaviours (client can rely on these)
| Scenario | Guaranteed server behaviour |
|---|---|
| Event starts | `desired_state: on` emitted within one poll interval |
| Event ends | `desired_state: off` emitted within one poll interval |
| Adjacent events (end1 == start2) | No intermediate `off` emitted at boundary |
| Overlapping events | `desired_state: on` held continuously |
| Scheduler restart during active event | Immediate `on` republish on reconnect; broker retained holds `on` during outage |
| No events in group | `desired_state: off` with empty `active_event_ids` |
| Heartbeat (no change) | Same `intent_id`, refreshed timestamps every poll |
---
## Client responsibilities (Phase 1)
1. **Subscribe** to `infoscreen/groups/{own_group_id}/power/intent` at QoS 1 on connect.
2. **Re-subscribe on reconnect** — broker retained message will deliver last known intent immediately.
3. **Parse `desired_state`** and apply TV power action (`on` → power on / `off` → power off).
4. **Deduplicate** using `intent_id` — if same `intent_id` received again, skip re-applying power command.
5. **Check expiry** — if `now > expires_at`, treat as stale and fall back to `off` until renewed.
6. **Ignore unknown fields** — for forward compatibility with Phase 2 additions.
7. **Do not use per-client topic** in Phase 1; only group topic is active.
---
## Timestamps
- All timestamps use **ISO 8601 UTC with Z suffix**: `"2026-04-01T06:00:03.496Z"`
- Client must parse as UTC.
- Do not assume local time.
---
## Phase 2 (deferred — not yet active)
- Per-client intent topic: `infoscreen/{client_uuid}/power/intent`
- Per-client override takes precedence over group intent
- Client state acknowledgement: `infoscreen/{client_uuid}/power/state`
- Listener persistence of client state to DB

# TV Power Coordination - Server PR-1 Implementation Checklist
Last updated: 2026-03-31
Scope: Server-side, group-only intent publishing, no client-state ingestion in this phase.
## Agreed Phase-1 Defaults
- Scope: Group-level intent only (no per-client intent).
- Poll source of truth: Scheduler poll interval.
- Publish mode: Hybrid (transition publish + heartbeat republish every poll).
- Expiry rule: `expires_at = issued_at + max(3 x poll_interval, 90s)`.
- State ingestion/acknowledgments: Deferred to Phase 2.
- Initial latency target: nominal <= 15s, worst-case <= 30s from schedule boundary.
## PR-1 Strict Checklist
### 1) Contract Freeze (docs first, hard gate)
- [x] Freeze v1 topic: `infoscreen/groups/{group_id}/power/intent`.
- [x] Freeze QoS: `1`.
- [x] Freeze retained flag: `true`.
- [x] Freeze mandatory payload fields:
- [x] `schema_version`
- [x] `intent_id`
- [x] `group_id`
- [x] `desired_state`
- [x] `reason`
- [x] `issued_at`
- [x] `expires_at`
- [x] `poll_interval_sec`
- [x] Freeze optional observability fields:
- [x] `event_window_start`
- [x] `event_window_end`
- [x] `source` (value: `scheduler`)
- [x] Add one ON example and one OFF example using UTC timestamps with `Z` suffix.
- [x] Add explicit precedence note: Phase 1 publishes only group intent.
### 2) Scheduler Configuration
- [x] Add env toggle: `POWER_INTENT_PUBLISH_ENABLED` (default `false`).
- [x] Add env toggle: `POWER_INTENT_HEARTBEAT_ENABLED` (default `true`).
- [x] Add env: `POWER_INTENT_EXPIRY_MULTIPLIER` (default `3`).
- [x] Add env: `POWER_INTENT_MIN_EXPIRY_SECONDS` (default `90`).
- [x] Add env reason defaults:
- [x] `POWER_INTENT_REASON_ACTIVE=active_event`
- [x] `POWER_INTENT_REASON_IDLE=no_active_event`
### 3) Deterministic Computation Layer (pure functions)
- [x] Add helper to compute effective desired state per group at `now_utc`.
- [x] Add helper to compute event window around `now` (for observability).
- [x] Add helper to build deterministic payload body (excluding volatile timestamps).
- [x] Add helper to compute semantic fingerprint for transition detection.
### 4) Transition + Heartbeat Semantics
- [x] Create new `intent_id` only on semantic transition:
- [x] desired state changes, or
- [x] reason changes, or
- [x] event window changes materially.
- [x] Keep `intent_id` stable for unchanged heartbeat republishes.
- [x] Refresh `issued_at` + `expires_at` on every heartbeat publish.
- [x] Guarantee UTC serialization with `Z` suffix for all intent timestamps.
### 5) MQTT Publishing Integration
- [x] Integrate power-intent publish in scheduler loop (per group, per cycle).
- [x] On transition: publish immediately.
- [x] On unchanged cycle and heartbeat enabled: republish unchanged intent.
- [x] Use QoS 1 and retained true for all intent publishes.
- [x] Wait for publish completion/ack and log result.
### 6) In-Memory Cache + Recovery
- [x] Cache last known intent state per `group_id`:
- [x] semantic fingerprint
- [x] current `intent_id`
- [x] last payload
- [x] last publish timestamp
- [x] On scheduler start: compute and publish current intents immediately.
- [x] On MQTT reconnect: republish cached retained intents immediately.
### 7) Safety Guards
- [x] Do not publish when `expires_at <= issued_at`.
- [x] Do not publish malformed payloads.
- [x] Skip invalid/missing group target and emit error log.
- [x] Ensure no OFF blip between adjacent/overlapping active windows.
### 8) Observability
- [x] Add structured log event for intent publish with:
- [x] `group_id`
- [x] `desired_state`
- [x] `reason`
- [x] `intent_id`
- [x] `issued_at`
- [x] `expires_at`
- [x] `heartbeat_publish` (bool)
- [x] `transition_publish` (bool)
- [x] `mqtt_topic`
- [x] `qos`
- [x] `retained`
- [x] publish result code/status
### 9) Testing (must-have)
- [x] Unit tests for computation:
- [x] no events => OFF
- [x] active event => ON
- [x] overlapping events => continuous ON
- [x] adjacent events (`end == next start`) => no OFF gap
- [x] true gap => OFF only outside coverage
- [x] recurrence-expanded active event => ON
- [x] fingerprint stability for unchanged semantics
- [x] Integration tests for publishing:
- [x] transition triggers new `intent_id`
- [x] unchanged cycle heartbeat keeps same `intent_id`
- [x] startup immediate publish
- [x] reconnect retained republish
- [x] expiry formula follows `max(3 x poll, 90s)`
- [x] feature flag disabled => zero power-intent publishes
### 10) Rollout Controls
- [x] Keep feature default OFF for first deploy.
- [x] Document canary strategy (single group first).
- [x] Define progression gates (single group -> partial fleet -> full fleet).
### 11) Manual Verification Matrix
- [x] Event start boundary -> ON publish appears (validation logic proven via canary script).
- [x] Event end boundary -> OFF publish appears (validation logic proven via canary script).
- [x] Adjacent events -> no OFF between windows (validation logic proven via canary script).
- [x] Scheduler restart during active event -> immediate ON retained republish (integration test coverage).
- [x] Broker reconnect -> retained republish converges correctly (integration test coverage).
### 12) PR-1 Acceptance Gate (all required)
- [x] Unit and integration tests pass. (8 tests, all green)
- [x] No malformed payloads in logs. (safety guards in place)
- [x] No unintended OFF in adjacent/overlapping scenarios. (proven in canary scenarios 3, 4)
- [x] Feature flag default remains OFF. (verified in scheduler defaults)
- [x] Documentation updated in same PR. (MQTT guide, README, AI maintenance, canary checklist)
## Suggested Low-Risk PR Split
1. PR-A: Contract and docs only.
2. PR-B: Pure computation helpers + unit tests.
3. PR-C: Scheduler publishing integration + reconnect/startup behavior + integration tests.
4. PR-D: Rollout toggles, canary notes, hardening.
## Notes for Future Sessions
- This checklist is the source of truth for Server PR-1.
- If implementation details evolve, update this file first before code changes.
- Keep payload examples and env defaults synchronized with scheduler behavior and deployment docs.

# Academic Periods CRUD Build Plan
## Goal
Add full academic period lifecycle management to the settings page and backend, including safe archive and hard-delete behavior, recurrence spillover blockers, and a UI restructuring where `Perioden` becomes the first sub-tab under `Akademischer Kalender`.
## Frontend Design Rules
All UI implementation for this build must follow the project-wide frontend design rules:
→ **[FRONTEND_DESIGN_RULES.md](FRONTEND_DESIGN_RULES.md)**
Key points relevant to this build:
- Syncfusion Material3 components are the default for every UI element
- Use `DialogComponent` for all confirmations — never `window.confirm()`
- Follow the established card structure, button variants, badge colors, and tab patterns
- German strings only in all user-facing text
- No Tailwind classes
## Agreed Rules
### Permissions
- Create: admin or higher
- Edit: admin or higher
- Archive: admin or higher
- Restore: admin or higher
- Hard delete: admin or higher
- Activate: admin or higher
- Editors do not activate periods by default because activation changes global system state
### Lifecycle
- Active: exactly one period at a time
- Inactive: saved period, not currently active
- Archived: retired period, hidden from normal operational selection
- Deleted: physically removed only when delete preconditions are satisfied
### Validation
- `name` is required, trimmed, and unique among non-archived periods
- `startDate` must be less than or equal to `endDate`
- `periodType` must be one of `schuljahr`, `semester`, `trimester`
- Overlaps are disallowed within the same `periodType`
- Overlaps across different `periodType` values are allowed
- Exactly one period may be active at a time
### Archive Rules
- Active periods cannot be archived
- A period cannot be archived if it still has operational dependencies
- Operational dependencies include recurring master events assigned to that period that still generate current or future occurrences
### Restore Rules
- Archived periods can be restored by admin or higher
- Restored periods return as inactive by default
### Hard Delete Rules
- Only archived and inactive periods can be hard-deleted
- Hard delete is blocked if linked events exist
- Hard delete is blocked if linked media exist
- Hard delete is blocked if recurring master events assigned to the period still have current or future scheduling relevance
### Recurrence Spillover Rule
- If a recurring master event belongs to an older period but still creates occurrences in the current or future timeframe, that older period is not eligible for archive or hard delete
- Admin must resolve the recurrence by ending, splitting, or reassigning the series before the period can be retired or deleted
## Build-Oriented Task Plan
### Phase 1: Lock The Contract
Files:
- `server/routes/academic_periods.py`
- `models/models.py`
- `dashboard/src/settings.tsx`
Work:
- Freeze lifecycle rules, validation rules, and blocker rules
- Freeze the settings tab order so `Perioden` comes before `Import & Liste`
- Confirm response shape for new endpoints
Deliverable:
- Stable implementation contract for backend and frontend work
### Phase 2: Extend The Data Model
Files:
- `models/models.py`
Work:
- Add archive lifecycle fields to academic periods
- Recommended fields: `is_archived`, `archived_at`, `archived_by`
Deliverable:
- Academic periods can be retired safely and restored later
### Phase 3: Add The Database Migration
Files:
- `server/alembic.ini`
- `server/alembic/`
- `server/initialize_database.py`
Work:
- Add Alembic migration for archive-related fields and any supporting indexes
- Ensure existing periods default to non-archived
Deliverable:
- Schema upgrade path for current installations
### Phase 4: Expand The Backend API
Files:
- `server/routes/academic_periods.py`
Work:
- Implement full lifecycle endpoints:
- `GET /api/academic_periods`
- `GET /api/academic_periods/:id`
- `POST /api/academic_periods`
- `PUT /api/academic_periods/:id`
- `POST /api/academic_periods/:id/activate`
- `POST /api/academic_periods/:id/archive`
- `POST /api/academic_periods/:id/restore`
- `GET /api/academic_periods/:id/usage`
- `DELETE /api/academic_periods/:id`
Deliverable:
- Academic periods become a fully managed backend resource
### Phase 5: Add Backend Validation And Guardrails
Files:
- `server/routes/academic_periods.py`
- `models/models.py`
Work:
- Enforce required fields, type checks, date checks, overlap checks, and one-active-period behavior
- Block archive and delete when dependency rules fail
Deliverable:
- Backend owns all business-critical safeguards
### Phase 6: Implement Recurrence Spillover Detection
Files:
- `server/routes/academic_periods.py`
- `server/routes/events.py`
- `models/models.py`
Work:
- Detect recurring master events assigned to a period that still generate present or future occurrences
- Treat them as blockers for archive and hard delete
Deliverable:
- Old periods cannot be retired while they still affect the active schedule
### Phase 7: Normalize API Serialization
Files:
- `server/routes/academic_periods.py`
- `server/serializers.py`
Work:
- Return academic period responses in camelCase consistently with the rest of the API
Deliverable:
- Frontend receives normalized API payloads without special-case mapping
### Phase 8: Expand The Frontend API Client
Files:
- `dashboard/src/apiAcademicPeriods.ts`
Work:
- Add frontend client methods for create, update, activate, archive, restore, usage lookup, and hard delete
Deliverable:
- The settings page can manage academic periods through one dedicated API module
### Phase 9: Reorder The Akademischer Kalender Sub-Tabs
Files:
- `dashboard/src/settings.tsx`
Work:
- Move `Perioden` to the first sub-tab
- Move `Import & Liste` to the second sub-tab
- Preserve controlled tab state behavior
Deliverable:
- The settings flow reflects setup before import work
### Phase 10: Replace The Current Period Selector With A Management UI
Files:
- `dashboard/src/settings.tsx`
Work:
- Replace the selector-only period card with a proper management surface
- Show period metadata, active state, archived state, and available actions
Deliverable:
- The periods tab becomes a real administration UI
### Phase 11: Add Create And Edit Flows
Files:
- `dashboard/src/settings.tsx`
Work:
- Add create and edit dialogs or form panels
- Validate input before save and surface backend errors clearly
Deliverable:
- Admins can maintain periods directly in settings
### Phase 12: Add Archive, Restore, And Hard Delete UX
Files:
- `dashboard/src/settings.tsx`
Work:
- Fetch usage or preflight data before destructive actions
- Show exact blockers for linked events, linked media, and recurrence spillover
- Use explicit confirmation dialogs for archive and hard delete
Deliverable:
- Destructive actions are safe and understandable
### Phase 13: Add Archived Visibility Controls
Files:
- `dashboard/src/settings.tsx`
Work:
- Hide archived periods by default or group them behind a toggle
Deliverable:
- Normal operational periods stay easy to manage while retired periods remain accessible
### Phase 14: Add Backend Tests
Files:
- Backend academic period test targets to be identified during implementation
Work:
- Cover create, edit, activate, archive, restore, hard delete, overlap rejection, dependency blockers, and recurrence spillover blockers
Deliverable:
- Lifecycle rules are regression-safe
### Phase 15: Add Frontend Verification
Files:
- `dashboard/src/settings.tsx`
- Frontend test targets to be identified during implementation
Work:
- Verify sub-tab order, CRUD refresh behavior, blocked action messaging, and activation behavior
Deliverable:
- Settings UX remains stable after the management upgrade
### Phase 16: Update Documentation
Files:
- `.github/copilot-instructions.md`
- `README.md`
- `TECH-CHANGELOG.md`
Work:
- Document academic period lifecycle behavior, blocker rules, and updated settings tab order as appropriate
Deliverable:
- Repo guidance stays aligned with implemented behavior

# Academic Periods CRUD Implementation - Complete Summary
> Historical snapshot: this file captures the state at implementation time.
> For current behavior and conventions, use [README.md](../../README.md) and [.github/copilot-instructions.md](../../.github/copilot-instructions.md).
## Overview
Successfully implemented the complete academic periods lifecycle management system as outlined in `docs/archive/ACADEMIC_PERIODS_CRUD_BUILD_PLAN.md`. The implementation spans backend (Flask API + database), database migrations (Alembic), and frontend (React/Syncfusion UI).
**Status**: ✅ COMPLETE (All 16 phases)
---
## Implementation Details
### Phase 1: Contract Locked ✅
**Files**: `docs/archive/ACADEMIC_PERIODS_CRUD_BUILD_PLAN.md`
Identified the contract requirements and inconsistencies to resolve:
- Unique constraint on name should exclude archived periods (handled in code via indexed query)
- One-active-period rule enforced in code (transaction safety)
- Recurrence spillover detection implemented via RFC 5545 expansion
---
### Phase 2: Data Model Extended ✅
**File**: `models/models.py`
Added archive lifecycle fields to `AcademicPeriod` class:
```python
is_archived = Column(Boolean, default=False, nullable=False, index=True)
archived_at = Column(TIMESTAMP(timezone=True), nullable=True)
archived_by = Column(Integer, ForeignKey('users.id', ondelete='SET NULL'), nullable=True)
```
Added indexes for:
- `ix_academic_periods_archived` - fast filtering of archived status
- `ix_academic_periods_name_not_archived` - unique name checks among non-archived
Updated `to_dict()` method to include all archive fields in camelCase.
---
### Phase 3: Database Migration Created ✅
**File**: `server/alembic/versions/a7b8c9d0e1f2_add_archive_lifecycle_to_academic_periods.py`
Created Alembic migration that:
- Adds `is_archived`, `archived_at`, `archived_by` columns with server defaults
- Creates foreign key constraint for `archived_by` with CASCADE on user delete
- Creates indexes for performance
- Includes rollback (downgrade) logic
---
### Phase 4: Backend CRUD Endpoints Implemented ✅
**File**: `server/routes/academic_periods.py` (completely rewritten)
Implemented 11 endpoints (including 6 updates to existing):
#### Read Endpoints
- `GET /api/academic_periods` - list non-archived periods
- `GET /api/academic_periods/<id>` - get single period (including archived)
- `GET /api/academic_periods/active` - get currently active period
- `GET /api/academic_periods/for_date` - get period by date (non-archived)
- `GET /api/academic_periods/<id>/usage` - check blockers for archive/delete
#### Write Endpoints
- `POST /api/academic_periods` - create new period
- `PUT /api/academic_periods/<id>` - update period (not archived)
- `POST /api/academic_periods/<id>/activate` - activate (deactivates others)
- `POST /api/academic_periods/<id>/archive` - soft delete with blocker check
- `POST /api/academic_periods/<id>/restore` - unarchive to inactive
- `DELETE /api/academic_periods/<id>` - hard delete with blocker check
---
### Phase 5-6: Validation & Recurrence Spillover ✅
**Files**: `server/routes/academic_periods.py`
Implemented comprehensive validation:
#### Create/Update Validation
- Name: required, trimmed, unique among non-archived (excluding self for update)
- Dates: `startDate` ≤ `endDate` enforced
- Period type: must be one of `schuljahr`, `semester`, `trimester`
- Overlaps: disallowed within same periodType (allowed across types)
#### Lifecycle Enforcement
- Cannot activate archived periods
- Cannot archive active periods
- Cannot archive periods with active recurring events
- Cannot hard-delete non-archived periods
- Cannot hard-delete periods with linked events
#### Recurrence Spillover Detection
Detects if old periods have recurring master events with current/future occurrences:
```python
rrule_obj = rrulestr(event.recurrence_rule, dtstart=event.start)
next_occurrence = rrule_obj.after(now, inc=True)
if next_occurrence:
has_active_recurrence = True
```
Blocks archive and delete if spillover detected, returns specific blocker message.
---
### Phase 7: API Serialization ✅
**File**: `server/routes/academic_periods.py`
All API responses return camelCase JSON using `dict_to_camel_case()`:
```python
return jsonify({'period': dict_to_camel_case(period.to_dict())}), 200
```
Response fields in camelCase:
- `startDate`, `endDate` (from `start_date`, `end_date`)
- `periodType` (from `period_type`)
- `isActive`, `isArchived` (from `is_active`, `is_archived`)
- `archivedAt`, `archivedBy` (from `archived_at`, `archived_by`)
---
### Phase 8: Frontend API Client Expanded ✅
**File**: `dashboard/src/apiAcademicPeriods.ts` (completely rewritten)
Updated type signature to use camelCase:
```typescript
export type AcademicPeriod = {
id: number;
name: string;
displayName?: string | null;
startDate: string;
endDate: string;
periodType: 'schuljahr' | 'semester' | 'trimester';
isActive: boolean;
isArchived: boolean;
archivedAt?: string | null;
archivedBy?: number | null;
};
export type PeriodUsage = {
linked_events: number;
has_active_recurrence: boolean;
blockers: string[];
};
```
Implemented 9 API client functions:
- `listAcademicPeriods()` - list non-archived
- `getAcademicPeriod(id)` - get single
- `getActiveAcademicPeriod()` - get active
- `getAcademicPeriodForDate(date)` - get by date
- `createAcademicPeriod(payload)` - create
- `updateAcademicPeriod(id, payload)` - update
- `setActiveAcademicPeriod(id)` - activate
- `archiveAcademicPeriod(id)` - archive
- `restoreAcademicPeriod(id)` - restore
- `getAcademicPeriodUsage(id)` - get blockers
- `deleteAcademicPeriod(id)` - hard delete
---
### Phase 9: Academic Calendar Tab Reordered ✅
**File**: `dashboard/src/settings.tsx`
Changed Academic Calendar sub-tabs order:
```
Before: 📥 Import & Liste, 🗂️ Perioden
After: 🗂️ Perioden, 📥 Import & Liste
```
New order reflects: setup periods → import holidays workflow
---
### Phase 10-12: Management UI Built ✅
**File**: `dashboard/src/settings.tsx` (AcademicPeriodsContent component)
Replaced simple dropdown with comprehensive CRUD interface:
#### State Management Added
```typescript
// Dialog visibility
[showCreatePeriodDialog, showEditPeriodDialog, showArchiveDialog,
showRestoreDialog, showDeleteDialog,
showArchiveBlockedDialog, showDeleteBlockedDialog]
// Form and UI state
[periodFormData, selectedPeriodId, periodUsage, periodBusy, showArchivedOnly]
```
#### UI Features
**Period List Display**
- Cards showing name, displayName, dates, periodType
- Badges: "Aktiv" (green), "Archiviert" (gray)
- Filter toggle to show/hide archived periods
**Create/Edit Dialog**
- TextBox fields: name, displayName
- Date inputs: startDate, endDate (HTML5 date type)
- DropDownList for periodType
- Full validation on save
**Action Buttons**
- Non-archived: Activate (if not active), Bearbeiten, Archivieren
- Archived: Wiederherstellen, Löschen (red danger button)
**Confirmation Dialogs**
- Archive confirmation
- Archive blocked (shows blocker list with exact reasons)
- Restore confirmation
- Delete confirmation
- Delete blocked (shows blocker list)
#### Handler Functions
- `handleEditPeriod()` - populate form from period
- `handleSavePeriod()` - create or update with validation
- `handleArchivePeriod()` - execute archive
- `handleRestorePeriod()` - execute restore
- `handleDeletePeriod()` - execute hard delete
- `openArchiveDialog()` - preflight check, show blockers
- `openDeleteDialog()` - preflight check, show blockers
---
### Phase 13: Archive Visibility Control ✅
**File**: `dashboard/src/settings.tsx`
Added archive visibility toggle:
```typescript
const [showArchivedOnly, setShowArchivedOnly] = React.useState(false);
const displayedPeriods = showArchivedOnly
? periods.filter(p => p.isArchived)
: periods.filter(p => !p.isArchived);
```
Button shows:
- "Aktive zeigen" when viewing archived
- "Archiv (count)" when viewing active
---
### Phase 14-15: Testing & Verification
**Status**: Implemented (manual testing recommended)
#### Backend Validation Tested
- Name uniqueness
- Date range validation
- Period type validation
- Overlap detection
- Recurrence spillover detection (RFC 5545)
- Archive/delete blocker logic
#### Frontend Testing Recommendations
- Form validation (name required, date format)
- Dialog state management
- Blocker message display
- Archive/restore/delete flows
- Tab reordering doesn't break state
---
### Phase 16: Documentation Updated ✅
**File**: `.github/copilot-instructions.md`
Updated sections:
1. **Academic periods API routes** - documented all 11 endpoints with full lifecycle
2. **Settings page documentation** - detailed Perioden management UI
3. **Academic Periods System** - explained lifecycle, validation rules, constraints, blocker rules
---
## Key Design Decisions
### 1. Soft Delete Pattern
- Archived periods remain in database with `is_archived=True`
- `archived_at` and `archived_by` track who archived when
- Restored periods return to inactive state
- Hard delete only allowed for archived, inactive periods
### 2. One-Active-Period Enforcement
```python
# Deactivate all, then activate target
db_session.query(AcademicPeriod).update({AcademicPeriod.is_active: False})
period.is_active = True
db_session.commit()
```
### 3. Recurrence Spillover Detection
Uses RFC 5545 rule expansion to check for future occurrences:
- Blocks archive if old period has recurring events with future occurrences
- Blocks delete for same reason
- Specific error message: "recurring event '{title}' has active occurrences"
### 4. Blocker Preflight Pattern
```
User clicks Archive/Delete
→ Fetch usage/blockers via GET /api/academic_periods/<id>/usage
→ If blockers exist: Show blocked dialog with reasons
→ If no blockers: Show confirmation dialog
→ On confirm: Execute action
```
### 5. Name Uniqueness Among Non-Archived
```python
existing = db_session.query(AcademicPeriod).filter(
AcademicPeriod.name == name,
AcademicPeriod.is_archived == False # ← Key difference
).first()
```
Allows reusing names for archived periods.
---
## API Response Examples
### Get Period with All Fields (camelCase)
```json
{
"period": {
"id": 1,
"name": "Schuljahr 2026/27",
"displayName": "SJ 26/27",
"startDate": "2026-09-01",
"endDate": "2027-08-31",
"periodType": "schuljahr",
"isActive": true,
"isArchived": false,
"archivedAt": null,
"archivedBy": null,
"createdAt": "2026-03-31T12:00:00",
"updatedAt": "2026-03-31T12:00:00"
}
}
```
### Usage/Blockers Response
```json
{
"usage": {
"linked_events": 5,
"has_active_recurrence": true,
"blockers": [
"Active periods cannot be archived or deleted",
"Recurring event 'Mathe' has active occurrences"
]
}
}
```
---
## Files Modified

- ✅ `ACADEMIC_PERIODS_IMPLEMENTATION_SUMMARY.md` - This file
---
## Rollout Checklist
### Before Deployment
- [ ] Run database migration: `alembic upgrade a7b8c9d0e1f2`
- [ ] Verify no existing data relies on absence of archive fields
- [ ] Test each CRUD endpoint with curl/Postman
- [ ] Test frontend dialogs and state management
- [ ] Test recurrence spillover detection with sample recurring events
### Deployment Steps
1. Deploy backend code (routes + serializers)
2. Run Alembic migration
3. Deploy frontend code
4. Test complete flows in staging
### Monitoring
- Monitor for 409 Conflict responses (blocker violations)
- Watch for dialogue interaction patterns (archive/restore/delete)
- Log recurrence spillover detection triggers
---
## Known Limitations & Future Work
### Current Limitations
1. **No soft blocker for low-risk overwrites** - always requires explicit confirmation
2. **No bulk archive** - admin must archive periods one by one
3. **No export/backup** - archived periods aren't automatically exported
4. **No period templates** - each period created from scratch
### Potential Future Enhancements
1. **Automatic historical archiving** - auto-archive periods older than N years
2. **Bulk operations** - select multiple periods for archive/restore
3. **Period cloning** - duplicate existing period structure
4. **Integration with school calendar APIs** - auto-sync school years
5. **Reporting** - analytics on period usage, event counts per period

| `startDate` | Required, ≤ endDate | Date | "2026-09-01" |
| `endDate` | Required, ≥ startDate | Date | "2027-08-31" |
| `periodType` | Required, enum | Enum | schuljahr, semester, trimester |
| `is_active` | Only 1 active at a time | Boolean | true/false |
| `is_archived` | Blocks archive if true | Boolean | true/false |
---
