Roadmap

ADP development follows a phased approach. This page tracks progress and planned work.

Phase 1: Stabilization & Testing ✅

All critical bugs resolved. Test coverage expanding across modules.

• Decoupled DebuggerAppDevPanel\Kernel\DebuggerClass Debugger.final Kernel · class from framework-specific events via StartupContextAppDevPanel\Kernel\StartupContextClass StartupContext.final Kernel · class
• Fixed shutdown registration, socket lifecycle, JSON error handling
• 755+ PHP tests, 328 frontend tests passing

Phase 2: Security Hardening ✅ (core)

Eliminated critical security vulnerabilities in the API.

• Path traversal protection on file endpoints
• Input validation for class names, git branches, locales, database queries
• Pagination limits on all list endpoints

Remaining: Authentication/authorization for inspector, CSRF protection, URL allowlist for request replay.

Phase 3: Performance Optimization ✅ (core)

• Optimized SSE poll interval (1s → 500ms)
• Reduced backtrace overhead (IGNORE_ARGS + depth limit)

Remaining: Frontend code splitting, list virtualization for large datasets.

Phase 4: Architecture Improvements 🔄

Backend improvements (mostly complete):

• Split monolithic InspectControllerAppDevPanel\Api\Inspector\Controller\InspectControllerInspect inspector API controller.final API · class into domain-specific controllers
• Replaced global ApplicationStateAppDevPanel\Api\Inspector\ApplicationStateClass ApplicationState.final API · class with proper DI
• Added file locking to FileStorageAppDevPanel\Kernel\Storage\FileStorageClass FileStorage.final Kernel · class · implements StorageInterface (atomic writes + non-blocking GC)
• Completed namespace migration to AppDevPanel

Remaining backend: Connection refactoring, CLI configurability, circular dependency guards.

Remaining frontend: TypeScript type generation from API, ErrorBoundary coverage, shared types package.

Phase 5: Ecosystem Growth 🔄

Multi-framework support:

Adapter	Status
Symfony	✅ Complete
Yii 2	✅ Complete
Yii 3	✅ Complete
Laravel	✅ Complete

See Feature Matrix for detailed adapter capabilities.

Phase 6: Observability & Documentation

• Structured logging for Kernel operations
• OpenAPI spec for the API
• Integration tests with real framework DI containers
