# Story 3.4d: Enterprise Distribution & LTS Policy

## Status: Planned

## Priority: Medium

## Estimated Effort: Small (1 day)

## Dependencies: None

## Epic / Series

Part of Epic 3: Plugin Ecosystem Foundation / Series 3.x

---

## Context / Background

Enterprise platform admins need private index support and clear LTS policies so they can operate plugins at scale. This includes documentation for private indexes and LTS policy publication.

---

## User Story

**As an** enterprise platform admin  
**I want** private index support and clear LTS policies  
**So that** I can operate plugins at scale

---

## Scope (In / Out)

### In Scope

- Documentation for private indexes (Artifactory/Nexus)
- Guidance for mirroring extras into internal repos
- Constraints files examples
- LTS policy (N–2) published in docs

### Out of Scope

- Implementing private index infrastructure
- LTS enforcement tooling
- Migration tools

---

## Acceptance Criteria

### AC1: Distribution Documentation

- [ ] Documentation for private indexes (Artifactory/Nexus)
- [ ] Guidance for mirroring extras into internal repos
- [ ] Examples for constraints/lockers
- [ ] Compatibility guidance

### AC2: LTS Policy

- [ ] Draft and publish LTS policy (N–2)
- [ ] Link from README
- [ ] Clear policy explanation
- [ ] Version support matrix

## Technical Design / Implementation Notes

### Documentation Structure

1. **Private Index Guide:**
   - Setting up Artifactory/Nexus
   - Configuring pip to use private index
   - Mirroring fapilog extras

2. **Constraints Files:**
   - Example constraints.txt
   - Version pinning strategies
   - Compatibility matrices

3. **LTS Policy:**
   - Support window definition
   - N–2 version support
   - Security update policy
   - End-of-life process

## Risks / Rollback / Monitoring

### Risks

- **Risk:** Documentation becomes outdated
  - **Mitigation:** Regular reviews, version documentation

- **Risk:** LTS policy too restrictive or too lenient
  - **Mitigation:** Review with stakeholders, adjust based on feedback

### Rollback Plan

- Documentation changes can be reverted
- Policy can be updated as needed
- No code changes, so easy to adjust

### Success Metrics / Monitoring

- Enterprise adoption feedback
- Policy clarity feedback
- Usage of private indexes
