# Chanora Verification Master Plan

**Document type:** Verification Master Plan  
**Version:** 0.9.2
**Status:** Baseline Candidate  
**Language:** English  
**Product:** Chanora  

**Repo path:** `docs/verification/verification-master-plan.md`  ---

## 1. Purpose

This document defines how Chanora verification documents relate to the engineering hierarchy.

Core engineering hierarchy:

```text
SysRS -> SysDes -> SRS -> SAD -> SDD
```

Verification work products are downstream evidence-producing artifacts and do not replace the hierarchy.

## 2. Verification Layers

| Process | Verification target | Direct verification source | Purpose |
|---|---|---|---|
| SWE.4 | Software units | SDD | Verify software units against detailed design |
| SWE.5 | Integrated software elements | SAD and SDD | Verify software architecture integration, interfaces, dynamic behavior, and component interaction |
| SWE.6 | Fully integrated software | SRS | Verify integrated software satisfies software requirements |
| SYS.4 | Integrated application system elements | SysDes | Verify system elements integrate according to system architecture |

## 3. Verification Flow

```text
SDD -> SWE.4 Unit Verification
SAD + SDD -> SWE.5 Software Integration Verification
SRS -> SWE.6 Software Verification
SysDes -> SYS.4 System Integration Verification
```

## 4. Regression Rule

A change in any design or requirement artifact shall trigger impact analysis for the corresponding verification layer:

| Changed artifact | Verification impact |
|---|---|
| SDD | SWE.4 and SWE.5 impact analysis |
| SAD | SDD, SWE.5, and possibly SWE.4 impact analysis |
| SRS | SAD, SDD, SWE.6, and related lower-level verification impact analysis |
| SysDes | SRS/SAD/SDD impact analysis and SYS.4 impact analysis |
| SysRS | SysDes/SRS/SAD/SDD impact analysis and system/software verification impact analysis |

## 5. Required Verification Reports

| Report | Source |
|---|---|
| Unit Verification Summary Report | SWE.4 |
| Software Integration Verification Summary Report | SWE.5 |
| Software Verification Summary Report | SWE.6 |
| System Integration Verification Summary Report | SYS.4 |
| Regression Verification Report | Any affected verification layer |
| Problem Resolution Report | Failed verification requiring defect handling |
