 # TaskSchema module
 ## Backend
- TaskSchema - TaskSchema entity 
-    - id, name, status, date, type, repeat, start, end
- TaskType - Enum for schema type
-    - single (create one task on date or null, delete schema after date or now if null)
-    - repeat (create tasks depending on repeat in start-end range, delete after enddate)
- TaskRepeat - Enum for schema repeat
-    - daily, weekly (array with weekdays), monthly (array with monthdays)
- TaskSchemaController - TaskSchema routes
-    - index, show, create, update, delete
- TaskSchemaManager - TaskSchema CRUD
-    - create, update, delete
- TaskSchemaRepository - TaskSchema queries
- TaskGenerator - Create tasks from schema
-    - generate
-
+- Task - add schema (n:1)
+- TaskSchema - id, name, status, taskStatus, date, repeat (json), start, end
+    - repeat=null → single, repeat={"daily"/"weekly"/"monthly":...} → repeating
+- TaskSchemaStatus - active, inactive
+- TaskController - remove create route
+- TaskManager - remove create
+- TaskSchemaController - index, show, create, update, delete
+- TaskSchemaManager - create (single=task only, repeat=schema+generate), update (remove+generate), delete (remove+schema)
+- TaskGenerator - generateTasks, removeTasks, generateNewTasks (scheduler)
+- Scheduler - daily at 03:00, messenger:consume via DDEV daemon
+- Migration - task_schema table + schema_id FK
+## Frontend
+- TaskCreate.vue removed, SchemaCreate/SchemaEdit/SchemaAll added
+- Task.vue + TaskAll.vue - calendar + plus icons → /schemas, /schemas/create
+- Form: name, (status + taskStatus), repeat, weekday/monthday grid, (start + end)
+## App
+- same changes as Frontend
+## Features
+- Single schema: task directly, no schema persisted
+- Repeat schema: tasks for period (max 14 days), scheduler fills daily
+- Update: remove non-past tasks + regenerate
+- Delete: remove non-past tasks + schema
