+# Plan: Cancellation Statistics Feature
+
+## Objective
+
+Enable stakeholders to see how often dispositions and applications have been canceled by either the teamer or the office, per hotel and for a given date range.
+
+---
+
+## Current State Analysis
+
+### Dispositions - Already Tracked
+
+The `Disposition` entity has comprehensive cancellation tracking:
+
+| Field | Type | Purpose |
+|-------|------|---------|
+| `status` | string | `'called_off'` when cancelled |
+| `calledOffBy` | string (nullable) | `'teamer'` or `'office'` |
+| `calledOffReason` | text (nullable) | Reason for cancellation |
+| `updatedAt` | datetime | Timestamp of last change |
+
+**Constants:**
+```php
+public const STATUS_CALLED_OFF = 'called_off';
+public const CALLED_OFF_BY_TEAMER = 'teamer';
+public const CALLED_OFF_BY_OFFICE = 'office';
+```
+
+**Cancellation entry points:**
+1. Individual disposition cancellation via `Administrative/Disposition/CallOffController`
+   - Form requires `calledOffBy` and `calledOffReason`
+   - Dispatches `DispositionCalledOffEvent`
+
+2. Full assignment cancellation via `Administrative/Assignment/CallOffController`
+   - Sets all dispositions to `calledOffBy = 'office'`
+   - Dispatches `AssignmentCalledOffEvent`
+
+### Applications - Missing Tracking
+
+The `Application` entity lacks cancellation tracking:
+
+| Current Field | Issue |
+|---------------|-------|
+| `status` | Only `'rejected'` - no distinction between teamer withdrawal and office rejection |
+| - | No `cancelledBy` field |
+| - | No `cancellationReason` field |
+
+**Current rejection mechanisms:**
+1. Manual rejection by office (no tracking of who)
+2. Automatic rejection by `RejectApplicationListener` when disposition slots fill
+3. Automatic removal by `InvalidateApplicationsListener` when teamer has overlapping confirmed dispositions
+
+---
+
+## Pending Decision
+
+**Question for stakeholders:** Should automatic rejections be included in statistics?
+
+| Option | Description | Impact |
+|--------|-------------|--------|
+| **Only user-initiated** | Count only manual cancellations by teamer or office | Simpler model, clearer accountability |
+| **Include automatic** | Also track system-initiated rejections | Full picture of lost applications, requires `'system'` category |
+
+**Status:** Awaiting stakeholder response
+
+---
+
+## Proposed Changes
+
+### Application Entity
+
+**Option A: If only user-initiated cancellations count**
+
+Add new status and fields:
+```php
+public const STATUS_WITHDRAWN = 'withdrawn';  // teamer-initiated
+public const STATUS_REJECTED = 'rejected';     // office-initiated (existing)
+
+private ?string $cancellationReason = null;
+```
+
+**Option B: If automatic rejections should be tracked**
+
+Add new status, fields, and constant:
+```php
+public const STATUS_WITHDRAWN = 'withdrawn';  // teamer-initiated
+public const STATUS_REJECTED = 'rejected';     // office or system initiated
+
+public const CANCELLED_BY_TEAMER = 'teamer';
+public const CANCELLED_BY_OFFICE = 'office';
+public const CANCELLED_BY_SYSTEM = 'system';
+
+private ?string $cancelledBy = null;
+private ?string $cancellationReason = null;
+```
+
+### Database Migration
+
+Add columns to `application` table:
+- `cancellation_reason` (LONGTEXT, nullable)
+- Possibly `cancelled_by` (VARCHAR(64), nullable) if Option B
+
+### Repository Methods
+
+Add to `ApplicationRepository`:
+```php
+/**
+ * @return array<string, array{teamer: int, office: int}>
+ */
+public function getCancellationStatsByHotel(
+    \DateTimeImmutable $startDate,
+    \DateTimeImmutable $endDate
+): array;
+```
+
+Add to `DispositionRepository`:
+```php
+/**
+ * @return array<string, array{teamer: int, office: int}>
+ */
+public function getCancellationStatsByHotel(
+    \DateTimeImmutable $startDate,
+    \DateTimeImmutable $endDate
+): array;
+```
+
+**Date filtering:** Based on assignment travel dates (confirmed in discussion).
+
+### Update Listeners (if Option B)
+
+Modify `RejectApplicationListener` and `InvalidateApplicationsListener` to set `cancelledBy = 'system'`.
+
+### UI Changes
+
+Add withdrawal functionality for teamers (if not already present) that sets `STATUS_WITHDRAWN`.
+
+---
+
+## Implementation Steps
+
+1. [ ] Finalize decision on automatic rejection tracking
+2. [ ] Add new constants and fields to `Application` entity
+3. [ ] Create database migration
+4. [ ] Update `ApplicationRepository` with statistics methods
+5. [ ] Update `DispositionRepository` with statistics methods
+6. [ ] Update listeners if tracking automatic rejections
+7. [ ] Add/update controllers for teamer withdrawal flow
+8. [ ] Write tests for new repository methods
+9. [ ] Run php-cs-fixer

+
+## Notes
+
+- Filter statistics by **assignment travel dates**, not cancellation timestamp
+- Disposition tracking already works - only need repository query methods
+- Application tracking requires entity changes and migration
+- Consider whether teamer self-service withdrawal exists or needs to be added
