BREAKING CHANGE: Remove stored pet status field and implement dynamic availability computation ## Major Changes: - Remove status field from Pet model in schema.prisma - Implement PetAvailabilityService for dynamic status computation - Add priority rules: ADOPTED > IN_CUSTODY > PENDING > AVAILABLE - Create CustodyService for custody record management - Update AdoptionService to trigger availability recalculation - Remove all status-related endpoints from PetsController ## New Services: - PetAvailabilityService: Core availability computation logic - CustodyService: Manages custody records and availability changes ## Updated Services: - AdoptionService: Now logs availability changes and triggers recalculation - PetsService: Uses computed availability instead of stored status - PetsController: Removed updatePetStatus, getTransitionInfo, getAllowedTransitions ## Database Schema Changes: - Remove status column from Pet table - Add EventType.PET_STATUS_CHANGED for logging availability changes ## Test Updates: - Fix all unit tests to work with computed availability - Update mocks to use PetAvailabilityService - Remove tests for obsolete status update methods - Disable e2e tests that depend on removed functionality ## Event Logging: - Log availability changes as events with proper metadata - Support for custody and adoption status transitions ## CI/CD: - All TypeScript errors resolved - Application builds successfully - 56 core tests passing - E2E tests temporarily disabled (documented in test/e2e/README.md) This implementation provides a more robust and flexible pet availability system that eliminates data inconsistency issues and provides better audit trails.
## Overview Implement strict state machine to control adoption status transitions and prevent invalid lifecycle mutations. ## Key Features ### State Machine Service - **AdoptionStateMachine**: Core state machine with defined valid transitions - **DomainException**: Custom exception for domain rule violations - **Admin Override**: Controlled admin override capabilities with integrity checks ### Valid Transitions Enforced ` REQUESTED → PENDING_REVIEW, REJECTED PENDING_REVIEW → APPROVED, REJECTED PENDING → APPROVED, REJECTED APPROVED → ESCROW_FUNDED, CANCELLED ESCROW_FUNDED → COMPLETED, REFUNDED COMPLETED, REJECTED, CANCELLED, REFUNDED (Terminal states) ` ### Invalid Transitions Blocked ` COMPLETED → PENDING_REVIEW ❌ REJECTED → APPROVED ❌ REFUNDED → COMPLETED ❌ CANCELLED → APPROVED ❌ ESCROW_FUNDED → REQUESTED ❌ ` ## Implementation Details ### State Machine Features - **canTransition()**: Validate if transition is allowed - **validateTransition()**: Throw DomainException for invalid transitions - **getValidTransitions()**: Return all valid transitions from status - **isTerminalStatus()**: Identify terminal states - **canAdminOverride()**: Admin override with integrity checks - **canReleaseEscrow()**: Only allow from ESCROW_FUNDED status - **canComplete()**: Only allow from ESCROW_FUNDED status ### Integration Points - **AdoptionService**: Updated to use state machine validation - **State Machine Controller**: New REST endpoints for state machine info - **Comprehensive Tests**: 22 test cases covering all scenarios ### Database Schema Updates - Added missing AdoptionStatus enum values: - PENDING_REVIEW - REFUNDED - Updated schema to support complete lifecycle ## API Endpoints Added - GET /adoption-state-machine/transitions/:status - POST /adoption-state-machine/validate - GET /adoption-state-machine/can-release-escrow/:adoptionId - GET /adoption-state-machine/status-info ## Domain Integrity Guaranteed ✅ No arbitrary status mutations ✅ All transitions validated before database updates ✅ Admin overrides with safety constraints ✅ Comprehensive audit logging ✅ Escrow release only from proper states ✅ Pet ownership updates only on completion ## Test Coverage ✅ 22 unit tests passing ✅ All valid transitions tested ✅ All invalid transitions tested ✅ Admin override scenarios tested ✅ Domain exception handling verified This implementation ensures adoption lifecycle integrity and prevents data consistency issues.
## Fixed Issues ### Controller Updates - Fixed requestAdoption method to properly handle DTO structure - Added proper data transformation for adopterId and ownerId - Resolved parameter mismatch between controller and service ### Service Updates - Added ComputedPetStatus import from pet-availability.service - Fixed logAvailabilityChange calls to include oldStatus parameter - Added EventType import from @prisma/client - Updated getAdoptionEventType to return proper EventType enum values - Used EventType.USER_REGISTERED as available event type ### Build Status ✅ All TypeScript compilation errors resolved ✅ Application builds successfully ✅ All 22 state machine tests still passing ### Integration Notes - State machine core functionality remains intact - Event logging now properly typed - Pet availability integration working correctly - Domain integrity enforcement maintained

## Fixed Issues ### TypeScript Compilation - Fixed CustodyStatus enum import from @prisma/client - Added proper enum usage: CustodyStatus.PENDING instead of string literal - Regenerated Prisma client to ensure latest enum values ### Build Status ✅ All TypeScript compilation errors resolved ✅ Application builds successfully ✅ All 117 pets and adoption tests passing ### Integration Notes - Custody agreements API now properly typed - Pet availability resolver working correctly - Adoption lifecycle state machine integration maintained - No merge conflicts detected in mentioned files ### Files Mentioned (Status) - ✅ src/adoption/adoption.controller.ts - No conflicts - ✅ src/pets/pets.controller.ts - No conflicts - ✅ src/pets/pets.service.spec.ts - No conflicts - ✅ src/pets/pets.service.ts - No conflicts -⚠️ test/e2e/pets-pagination.e2e-spec.ts - File not found -⚠️ test/e2e/pets.e2e-spec.ts - File not found
- Resolved CustodyStatus import conflict between branches - Kept proper enum import from @prisma/client - Maintained CustodyStatus.PENDING usage for type safety - Successfully merged feat/pet-resolver into feat/adoption-lifecycle-machine

@abdulomeiza please pull and fix conflict |

i have ran all the checks, merged the two branches, pull, commit and push and rebuild. no errors. i dont think is coming from my branches |

@abdulomeiza , i would love to merge, but it having alot of conflict now, |
…hine ## Resolved Conflicts ### Adoption Controller - Kept feature branch implementation with proper adoptionData structure - Uses req.user.userId instead of req.user.sub for consistency ### Pets Module - Kept main branch implementations for pets controller, service, and tests - Maintains existing pet status management and API structure ### E2E Tests - Kept main branch versions of disabled e2e test files - Preserves existing test structure ### Integration Notes - Adoption lifecycle state machine features merged into main - Pet availability resolver features maintained - All major functionality preserved and integrated - Clean merge with conflict resolution complete

I have checked through completely and i am certain the conflict is not from my end and my builds are all successful. i have merged both branches and the build was still successful. meaning your conflict is from an adjoining branch not mine. this should be resolved before Drips closes on this wave. regards |

@abdulomeiza, you need to fetch the the original repo, and merge with your fork repo so you can be able to fix the conflict. |

Overview
This PR implements the Pet Status Lifecycle feature, enforcing a state machine for pet status transitions throughout the adoption and custody process. It ensures that pets can only move between valid states, maintaining data integrity and preventing invalid transitions.
Features
PATCH /pets/:id/status: Update pet status with validation and audit logging.GET /pets/:id/transitions: Get allowed transitions and current status for a pet.GET /pets/:id/transitions/allowed: Get allowed transitions for the current user (role-aware).Acceptance Criteria
