# FRS

*Functional Requirements Specification*

# Functional Requirements Specification: markidocx

## 1. Definition

This Functional Requirements Specification defines the externally observable behaviors and required functions of **markidocx**, a system for controlled **Markdown ↔ DOCX round-trip editing**.

The FRS specifies what markidocx must do from the perspective of users, external systems, and exposed interfaces. It defines required functions for:

* document build and export
* document import and reconstitution
* multi-file composition
* template and style management
* feature-level document processing
* validation and drift reporting
* local CLI usage
* REST-based service interaction
* MCP-based tool interaction
* end-to-end regression execution

This FRS is derived from the markidocx PRD and serves as the binding functional contract for implementation and acceptance.

---

## 2. Context

markidocx is intended to support documentation workflows in which:

* structured content is maintained in Markdown
* editorial review is performed in Microsoft Word
* document generation must be repeatable and inspectable
* multiple stakeholders and systems interact with the same documentation assets

The system acts as a functional bridge between:

* canonical Markdown source documents
* Word-based review artifacts
* automated documentation pipelines
* external tools and agents

Functionally, the system must allow content to move between these contexts while preserving supported structure and surfacing any drift or ambiguity introduced during the process.

---

## 3. Core Concepts

### 3.1 System Function

A system function is a user-visible or interface-visible capability the system provides, such as building a DOCX artifact, importing an edited document, or validating a template registration.

### 3.2 Externally Observable Behavior

Externally observable behavior includes all results visible through the CLI, REST interface, MCP interface, output artifacts, reports, and return statuses.

### 3.3 Requirement Statement

Each requirement in this document is written as a declarative, testable statement describing required system behavior.

### 3.4 Input–Output Relationship

markidocx receives manifests, Markdown sources, templates, styles, DOCX files, and configuration inputs and produces artifacts, reports, validation outcomes, and structured metadata.

### 3.5 Traceability

The requirements in this FRS are intended to trace back to the markidocx PRD and forward into implementation, interface contracts, and validation suites.

---

## 4. Scope and Non-Scope

### In Scope

This FRS covers:

* functional system behavior
* user-facing and interface-facing commands and operations
* supported document processing behavior
* interface-level interactions through CLI, REST, and MCP
* functional handling of templates, styles, manifests, and artifacts
* conditions under which functions succeed, warn, or fail

### Out of Scope

This FRS does not define:

* internal architecture
* code organization
* algorithms or parser strategies
* storage implementation
* UI layout
* deployment topology
* performance or security design except where behaviorally relevant

---

## 5. System Overview

markidocx shall provide a functional workflow in which a user or external system can:

1. define a document project using Markdown sources and a manifest
2. compose one or more Markdown files into a document model
3. export that document into DOCX using a selected template/style family
4. import an edited DOCX back into Markdown form
5. validate compatibility and structural integrity
6. detect and report drift between baseline and re-imported forms
7. manage template/style families
8. access the same capabilities locally, via service calls, or through MCP tools
9. run end-to-end tests using the latest stable markidocx documentation corpus

---

Requirements are grouped into the following domains:

* FR-100 Project and manifest management
* FR-200 Build and export
* FR-300 Import and round-trip processing
