Implemented a structured exception-handling mechanism in the
domain layer with the addition of `DomainException`,
`DomainValidationException`, `NotFoundException`, and
`PdfProcessingException` classes. These exceptions provide
specific error handling for domain logic and integrate with
centralized middleware.
Updated `ROADMAP.md` to mark Step 2.1 (Domain Exceptions) as
completed and Step 2.2 (Value Objects) as the next task.
Added timeline entries to reflect progress.
Cleaned up `DocumentOperator.Domain.csproj` by removing
unused folder inclusions, indicating a project structure
reorganization.
- Updated section headers with emojis for better navigation.
- Added "Last Updated" date and project status to the header.
- Corrected German umlauts and special characters for encoding.
- Improved formatting of "TABLE OF CONTENTS" and "PROJECT OVERVIEW."
- Replaced ASCII diagrams with modern box-based structures.
- Clarified dependency rules and workflow diagrams with arrows (→).
- Highlighted benefits using checkmarks (✅) for key sections.
- Removed Ardalis.Result and marked it with ❌ in "TECHNOLOGY STACK."
- Enhanced "DEVELOPMENT ROADMAP" with emoji-based phase statuses.
- Improved overall consistency, clarity, and visual appeal.
Introduced a comprehensive roadmap in `ROADMAP.md` to outline
the vision, purpose, and development phases of the
`DocumentOperator` service. Key additions include:
- Table of contents for navigation.
- Project overview with problem statement, solution, and core
features.
- Business workflow description for API operations.
- Architecture and design decisions:
- Clean Architecture principles and dependency rules.
- CQRS with MediatR and Vertical Slice Architecture.
- Exception-based error handling and Minimal APIs.
- Multi-tenancy strategy using API keys.
- Technology stack and detailed project structure.
- Development roadmap with nine phases, highlighting current
progress (Phase 1 completed, Phase 2 in progress).
- Learning notes, references, and an update log.
The roadmap serves as a living document to guide development
and ensure alignment on goals and strategies.
