Updated PHASENPLAN and ROADMAP to reflect progress on Feature 1 - ValidatePDF (75% complete). Marked Step 1.1 as completed, including MediatR setup, pipeline behaviors (`ValidationBehavior`, `LoggingBehavior`), ValidatePDF feature (Query, Handler, Validator), and DTOs.
Added `DependencyInjection.cs` for Application Layer DI configuration. Introduced `LoggingBehavior` and `ValidationBehavior` for MediatR pipelines. Implemented `ValidatePdfHandler`, `ValidatePdfQuery`, and `ValidatePdfValidator`.
Created DTOs (`ValidatePdfRequest`, `ValidatePdfResponse`) for the ValidatePDF feature. Added unit tests for `ValidatePdfHandler` to verify metadata handling and exception propagation.
Removed unused folder references in `DocumentOperator.Application.csproj`.
Updated PROJECT_STATUS.md, ROADMAP.md, and PHASENPLAN.md to adopt a feature-driven development approach. Replaced the layer-by-layer methodology with a focus on delivering complete, testable features.
Key changes:
- PROJECT_STATUS.md: Added detailed status updates, milestones, and removed Azure dependencies in favor of local solutions (e.g., temp folders, in-memory queues).
- ROADMAP.md: Restructured tasks by feature (e.g., ValidatePDF, ExtractAttachments) with detailed steps and acceptance criteria. Introduced cross-cutting concerns like multi-tenancy and resilience.
- PHASENPLAN.md: Introduced a week-by-week breakdown, progress tracking, and next steps for each feature.
These changes improve clarity, align tasks with deliverables, and provide a clear roadmap for project completion.
