# UCC
*Use Case Catalog*
# Use Case Catalog: markidocx
**System Scope:** markidocx
**Artifact Type:** Use Case Catalog
**Purpose:** Structured catalog of actor-goal-centered use cases for the markidocx round-trip editing system
**Status:** Draft
**Version:** 1.0
**Parent Artifacts:** PRD markidocx, FRS markidocx
---
# 1. Definition
This Use Case Catalog defines the externally observable functional behavior of **markidocx** from the perspective of its actors.
markidocx enables controlled **Markdown ↔ DOCX round-trip editing** with support for:
* local CLI usage
* REST-based service interaction
* MCP-based agent interaction
* template/style-driven document generation
* multi-file composition
* feature-level processing
* validation and drift detection
* end-to-end regression based on the latest stable markidocx documentation corpus
This catalog organizes the major actor goals that the system must support and provides structured use case descriptions suitable for traceability into the FRS and acceptance artifacts.
---
# 2. Context
markidocx sits between structured Markdown authoring and Word-centric editorial collaboration.
Its main functional challenge is not simple format conversion, but **managed round-trip behavior** under defined semantic constraints.
The catalog therefore focuses on use cases where actors need to:
* define a document project
* inspect and validate project readiness
* build review artifacts
* import edited DOCX files back into Markdown
* preserve or recover structure in multi-file projects
* apply template/style families
* detect drift
* automate workflows through service interfaces
* access the system through agentic tooling
This UCC is positioned between product goals and detailed functional requirements.

# 4. Use Case Levels
The catalog uses three abstraction levels:

1. The actor requests end-to-end regression execution.
2. The system loads the stable documentation corpus.
3. The system validates the documentation project.
4. The system builds required output artifacts.
5. The system performs import and comparison flows as defined by the regression profile.
6. The system records and reports regression outcomes.
### Extensions
* **3a.** The documentation project is no longer valid.
The system reports regression cannot proceed successfully.
* **5a.** Drift exceeds acceptable thresholds.
The system marks regression with warnings or failure.

# 9. Lifecycle Metadata Guidance
Each use case in the managed catalog should support the following governance metadata:
* **Status:** draft, active, deprecated, retired
* **Owner:** responsible role or team
* **Version introduced**
* **Last review date**
* **Trace links:** PRD sections, FRS IDs, test suites
* **Change note**
Suggested default metadata model:
```yaml
use_case:
id: UC-004
name: Build DOCX review artifact
status: active
owner: product-management
version_introduced: "1.0"
last_review: "2026-03-14"

- Actor inspects the multi-file project
- Actor validates the project
- Actor builds a single DOCX review artifact
- Reviewer edits the DOCX
- Actor imports the edited DOCX into the project context
- System attempts source-aware redistribution
- System either redistributes content or provides a managed fallback
- Actor runs drift comparison
- System returns redistribution status and drift results

# 12. Concise Summary
This UCC gives markidocx a proper **actor-goal-centered functional backbone**. It expands the earlier use cases into a governed catalog that can now serve as the bridge between:
* PRD intent
* FRS requirement groups
* acceptance test design
* later API and schema contracts
The strongest next step is to derive either:
1. an **acceptance criteria catalog** from these use cases, or
2. a **machine-readable UCC schema pack** with one YAML file per use case plus an index manifest.
