# Software Requirements Specification (SRS)_ [System or Workstream Name]

**Date:** [YYYY-MM-DD]  
**Status:** [Draft | In Review | Approved]  
**Owner:** [Name]  
**Reviewers:** [Names]  
**Scope:** [Technical system boundary]  
**Purpose:** Define the technical requirements, interfaces, constraints, and acceptance criteria for implementation.

## 1. Purpose

State what technical system is being specified and why.

## 2. System Context

Describe where the system lives inside Project Velocity and what it integrates with.

## 3. Assumptions and Constraints

State:

- runtime assumptions
- infrastructure assumptions
- compatibility constraints
- legal or licensing constraints

## 4. Functional Architecture

Describe the runtime layers, modules, or services.

## 5. Functional Requirements

For each requirement, include:

- requirement ID
- description
- producer and consumer if relevant
- acceptance criteria

## 6. Interface Requirements

Specify:

- APIs
- internal service interfaces
- event contracts
- schema boundaries

## 7. Data Model

Describe entities, artifacts, identifiers, and lifecycle fields.

## 8. Non-Functional Requirements

### 8.1 Reliability

Define uptime, retry, or failure-handling expectations.

### 8.2 Scalability

Define concurrency, throughput, or growth assumptions.

### 8.3 Security

Define access control, auth, and approval expectations.

### 8.4 Privacy

Define redaction, least-privilege, and data exposure rules.

### 8.5 Observability

Define metrics, traces, and logs.

### 8.6 Fault Tolerance

Define degraded behavior and replay strategy.

### 8.7 Licensing

Define upstream provenance and redistribution constraints if relevant.

## 9. Evaluation and Testing Strategy

Describe:

- unit testing
- integration testing
- replay testing
- governance testing

## 10. Migration and Fork Plan

Describe:

- what is forked
- what remains upstream-compatible
- what migration path exists from current state

## 11. Open Questions

List unresolved technical issues.

## 12. Acceptance Criteria

Define the completion gate for engineering.
