+# Implementation Plan: Auto-Delete Expired Events
+
+**Branch**: `013-auto-delete-expired` | **Date**: 2026-03-09 | **Spec**: [spec.md](spec.md)
+**Input**: Feature specification from `/specs/013-auto-delete-expired/spec.md`
+
+## Summary
+
+Add a scheduled background job that runs daily and deletes all events whose `expiryDate` has passed. Deletion is performed via a native SQL query (`DELETE FROM events WHERE expiry_date < CURRENT_DATE`). Cascade deletion of RSVPs is handled by the existing `ON DELETE CASCADE` FK constraint. No API or frontend changes required.
+
+## Technical Context
+
+**Language/Version**: Java 25, Spring Boot 3.5.x
+**Primary Dependencies**: Spring Scheduling (`@Scheduled`), Spring Data JPA (for native query)
+**Storage**: PostgreSQL (existing, Liquibase migrations)
+**Testing**: JUnit 5, Spring Boot Test, Testcontainers (existing)
+**Target Platform**: Linux server (Docker)
+**Project Type**: Web service (backend only for this feature)
+**Performance Goals**: N/A — daily batch job on small dataset
+**Constraints**: Single native DELETE query, no entity loading
+**Scale/Scope**: Self-hosted, small-scale — typically < 100 events total
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+| Principle | Status | Notes |
+|-----------|--------|-------|
+| I. Privacy by Design | PASS | Deleting expired data supports privacy goals. No PII logged. |
+| II. Test-Driven Methodology | PASS | Tests written before implementation (TDD). |
+| III. API-First Development | N/A | No API changes — this is a backend-internal job. |
+| IV. Simplicity & Quality | PASS | Single query, no over-engineering. |
+| V. Dependency Discipline | PASS | Uses only existing Spring dependencies (`@Scheduled`). |
+| VI. Accessibility | N/A | No frontend changes. |

+
+**Structure Decision**: Backend-only change. Follows existing hexagonal architecture: port defines the contract, adapter implements with native query, service layer schedules the job.
+
+## Design
+
+### Hexagonal Flow
+
+```
+@Scheduled trigger
+    → ExpiredEventCleanupJob (application/service)
+        → EventRepository.deleteExpired() (domain/port/out)
+            → EventPersistenceAdapter.deleteExpired() (adapter/out/persistence)
+                → EventJpaRepository native query (adapter/out/persistence)
+                    → DELETE FROM events WHERE expiry_date < CURRENT_DATE
+```
+
+### Key Decisions
+
+1. **Port method**: `int deleteExpired()` on `EventRepository` — returns count of deleted events for logging.
+2. **Native query**: `@Modifying @Query(value = "DELETE FROM events WHERE expiry_date < CURRENT_DATE", nativeQuery = true)` on `EventJpaRepository`.
+3. **Schedule**: `@Scheduled(cron = "0 0 3 * * *")` — runs daily at 03:00 server time. Low-traffic window.
+4. **Logging**: INFO-level log after each run: `"Deleted {count} expired event(s)"`. No log if count is 0 (or DEBUG-level).
+5. **Transaction**: The native DELETE runs in a single transaction — atomic, no partial state.
+6. **Enable scheduling**: Add `@EnableScheduling` to `FeteApplication` (or a config class).

+# Research: Auto-Delete Expired Events
+
+**Feature**: 013-auto-delete-expired | **Date**: 2026-03-09
+
+## Deletion Strategy
+
+- **Decision**: Direct native SQL DELETE query via Spring Data JPA `@Query`.
+- **Rationale**: Simplest approach. No entity loading overhead. The existing `ON DELETE CASCADE` FK constraint on `fk_rsvps_event_id` (migration `003-create-rsvps-table.xml`) handles cascading deletion of RSVPs automatically. The existing `idx_events_expiry_date` index ensures the WHERE clause is efficient.
+- **Alternatives considered**:
+  - JPA repository `deleteAll(findExpired())`: Loads entities into memory first, unnecessary overhead.
+  - Database-level cron (`pg_cron`): Less portable, adds external dependency.
+  - Soft delete with lazy cleanup: Over-engineered for fete's scale and privacy goals.
+  - No deletion (filter only): Contradicts privacy-by-design principle.
+
+## Scheduling Mechanism
+
+- **Decision**: Spring `@Scheduled(cron = ...)` annotation.
+- **Rationale**: Already available in Spring Boot, no additional dependencies. Simple, declarative, well-tested.
+- **Alternatives considered**:
+  - Quartz Scheduler: Too heavy for a single daily job.
+  - External cron (OS-level): Requires separate process management, harder to test.
+
+## Transaction Behavior
+
+- **Decision**: Single transaction for the DELETE statement.
+- **Rationale**: A single `DELETE FROM events WHERE expiry_date < CURRENT_DATE` is atomic. If the DB connection drops mid-execution, the transaction rolls back and no events are partially deleted. The next run picks up all expired events.
+
+## Enabling @Scheduled
+
+- **Decision**: Add `@EnableScheduling` to `FeteApplication.java`.
+- **Rationale**: Simplest approach. Only one scheduled job exists, no need for a separate config class.

+A scheduled background job periodically checks all events. Any event whose `expiryDate` is in the past gets permanently deleted — including all associated data (RSVPs, tokens). No user action is required; the system handles this autonomously.
+
+**Why this priority**: This is the core and only feature — automated, hands-off cleanup of expired events. It directly supports the privacy promise of fete.
+
+**Independent Test**: Can be fully tested by creating events with past expiry dates, triggering the cleanup job, and verifying the events are gone from the database.
+
+**Acceptance Scenarios**:
+
+1. **Given** an event with an `expiryDate` in the past, **When** the scheduled cleanup job runs, **Then** the event and all its associated data (RSVPs, tokens) are permanently deleted.
+2. **Given** an event with an `expiryDate` in the future, **When** the scheduled cleanup job runs, **Then** the event remains untouched.
+3. **Given** multiple expired events exist, **When** the cleanup job runs, **Then** all expired events are deleted in a single run.
+4. **Given** no expired events exist, **When** the cleanup job runs, **Then** nothing is deleted and the job completes without error.
+
+---
+
+### Edge Cases
+
+- What happens if the cleanup job fails mid-deletion (e.g., database connection lost)? Events that were not yet deleted remain and will be picked up in the next run. No partial state.
+- What happens if the server was offline for an extended period? On the next run, all accumulated expired events are deleted — no special catch-up logic needed.
+- What happens if an organizer is viewing their event page while it gets deleted? The page shows a "not found" state on next interaction. This is acceptable because the event has expired.
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: System MUST automatically delete events whose `expiryDate` is before the current date/time.
+- **FR-002**: When an event is deleted, all associated data (RSVPs, organizer tokens, event tokens) MUST be deleted as well (cascade delete).
+- **FR-003**: The cleanup job MUST run on a recurring schedule (default: once daily).
+- **FR-004**: The cleanup job MUST be idempotent — running it multiple times produces the same result.
+- **FR-005**: The cleanup job MUST log how many events were deleted per run.
+- **FR-006**: Events that have not yet expired MUST NOT be affected by the cleanup job.
+
+### Key Entities
+
+- **Event**: The primary entity being cleaned up. Has an `expiryDate` field that determines when it becomes eligible for deletion.
+- **RSVP**: Associated guest responses linked to an event. Deleted when the parent event is deleted.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: Expired events are deleted within 24 hours of their expiry date without manual intervention.
+- **SC-002**: Zero data residue — when an event is deleted, no orphaned RSVPs or tokens remain in the system.
+- **SC-003**: The cleanup process completes without errors under normal operating conditions.
+- **SC-004**: Non-expired events are never affected by the cleanup process.
+
+## Clarifications
+
+### Session 2026-03-09
+
+- Q: How should deletion be implemented — application code (JPA) or direct database query? → A: Direct database query. A single native `DELETE FROM events WHERE expiry_date < CURRENT_DATE` is sufficient. The existing `ON DELETE CASCADE` on the RSVPs foreign key ensures associated data is removed automatically. The existing `idx_events_expiry_date` index ensures the query is performant.
+
+## Assumptions
+
+- The `expiryDate` field already exists on events and is auto-set to `eventDate + 7 days` (implemented in the previous feature).
+- Cascade deletion of associated data (RSVPs, tokens) is handled at the database level via foreign key constraints (`ON DELETE CASCADE` on `fk_rsvps_event_id`, verified in migration `003-create-rsvps-table.xml`).
+- The daily schedule is sufficient — there is no requirement for near-real-time deletion.
+- No "grace period" or "soft delete" is needed — events are permanently removed once expired.

+# Tasks: Auto-Delete Expired Events
+
+**Input**: Design documents from `/specs/013-auto-delete-expired/`
+**Prerequisites**: plan.md, spec.md, research.md, data-model.md
+
+**Tests**: Included — constitution mandates TDD (Principle II).
+
+**Organization**: Single user story (US1), so phases are compact.
+
+## Format: `[ID] [P?] [Story] Description`
+
+- **[P]**: Can run in parallel (different files, no dependencies)
+- **[Story]**: Which user story this task belongs to (e.g., US1)
+- Include exact file paths in descriptions
+
+---
+
+## Phase 1: Setup
+
+**Purpose**: Enable Spring scheduling in the application.
+
+- [x] T001 Add `@EnableScheduling` annotation to `backend/src/main/java/de/fete/FeteApplication.java`
+
+---
+
+## Phase 2: User Story 1 — Automatic Cleanup of Expired Events (Priority: P1)
+
+**Goal**: A daily scheduled job deletes all events whose `expiryDate` is in the past, including cascaded RSVPs.
+
+**Independent Test**: Create events with past expiry dates, trigger the cleanup job, verify events and RSVPs are gone.
+
+### Tests for User Story 1
+
+> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**
+
+- [x] T002 [P] [US1] Unit test for `ExpiredEventCleanupJob` in `backend/src/test/java/de/fete/application/service/ExpiredEventCleanupJobTest.java` — verify job calls `deleteExpired()` on repository and logs the count
+- [x] T003 [P] [US1] Integration test for native DELETE query in `backend/src/test/java/de/fete/adapter/out/persistence/EventPersistenceAdapterIntegrationTest.java` — verify expired events + RSVPs are deleted, non-expired events survive
+
+### Implementation for User Story 1
+
+- [x] T004 [P] [US1] Add `int deleteExpired()` method to port interface `backend/src/main/java/de/fete/domain/port/out/EventRepository.java`
+- [x] T005 [P] [US1] Add native `@Modifying @Query("DELETE FROM events WHERE expiry_date < CURRENT_DATE")` method to `backend/src/main/java/de/fete/adapter/out/persistence/EventJpaRepository.java`
+- [x] T006 [US1] Implement `deleteExpired()` in `backend/src/main/java/de/fete/adapter/out/persistence/EventPersistenceAdapter.java` — delegates to JPA repository native query
+- [x] T007 [US1] Create `ExpiredEventCleanupJob` with `@Scheduled(cron = "0 0 3 * * *")` in `backend/src/main/java/de/fete/application/service/ExpiredEventCleanupJob.java` — calls `deleteExpired()`, logs count at INFO level
+
+**Checkpoint**: All tests pass. Expired events are automatically deleted daily at 03:00.
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies — can start immediately
+- **User Story 1 (Phase 2)**: Depends on Setup completion
+
+### Within User Story 1
+
+- T002, T003 (tests) can run in parallel — write first, must fail (RED)
+- T004, T005 (port + JPA query) can run in parallel — different files
+- T006 depends on T004 + T005 (adapter implements port, delegates to JPA)
+- T007 depends on T006 (job calls adapter via port)
+- After T007: all tests should pass (GREEN)
+
