# Product Requirements Document: QA2 - CI/CD Foundation & Testing Infrastructure

**Document:** PRD  
**Version:** 1.0  
**Feature ID:** qa2  
**Status:** Draft  
**Created:** October 30, 2025

---

## 1. Executive Summary

Create automated testing infrastructure and CI/CD pipelines to catch regressions, enforce code quality standards, and secure sensitive data. Developers see PR comments with coverage changes, tests run automatically, and merges are blocked if quality gates fail.

**See also:** [BRD § 3 Business Goals](../brds/qa2-brd.md#3-business-goals) for strategic context.

---

## 2. Problem Statement

Developers currently:
- Cannot detect regressions until production
- Cannot see code quality trends over time
- Accidentally commit sensitive data (tokens, emails, API keys)
- Maintain 82 completely untested files
- Have no enforcement mechanism for code quality standards

Result: Low team confidence in releases, security incidents, and inability to scale safely.

---

## 3. Business Objectives (from BRD)

See [BRD § 3 Business Goals](../brds/qa2-brd.md#3-business-goals):
- Prevent regressions automatically
- Enable safe scaling
- Reduce security incidents
- Establish quality standards
- Build customer trust

---

## 4. User Goals

1. **Developer as Code Author** - "I want my code reviewed automatically so I catch issues before my team reviews"
2. **Dev Lead as Release Manager** - "I want to block merges on critical issues so nothing bad reaches production"
3. **Security Officer as Compliance Owner** - "I want all sensitive data redacted from logs so we meet audit requirements"
4. **QA Engineer as Quality Advocate** - "I want coverage trends tracked so I can identify untested code"

---

## 5. Functional Requirements

| R# | Requirement | User Impact |
|----|--------------|----|
| **R1** | Lint + type-check on every commit | Catch errors before they reach code review |
| **R2** | Run tests on all PRs automatically | Verify nothing broke with this change |
| **R3** | Show coverage diff in PR comments | See if new code is tested vs baseline |
| **R4** | Block merge if tests fail | Prevent regressions from reaching main |
| **R5** | Redact sensitive data from logs | Prevent tokens/emails from leaking |
| **R6** | Track code complexity trends | Identify functions getting too complex |

---

## 6. User Stories

| Actor | User Story | Acceptance Criteria |
|-------|-----------|-------------------|
| Developer | As a code author, I want lint errors reported in my PR so I fix style issues immediately | PR shows 5 lint errors with file:line references |
| Developer | As a code author, I want my tests to run automatically so I know if I broke anything | PR shows ✅ all 247 tests pass in <5 min |
| Developer | As a code author, I want coverage diff displayed so I know if new code is tested | PR comment shows "Coverage: 42% → 44% (+2%) on changed files" |
| Dev Lead | As release manager, I want to block merges on low coverage so untested code never lands | Merge button disabled if coverage <50% on new code |
| Security | As security officer, I want GitHub tokens redacted from logs so we meet compliance | grep for "ghp_" in logs returns 0 results |
| QA | As QA engineer, I want coverage reports archived for 30 days so I can track trends | Historical coverage graph shows trend over time |

---

## 7. User Journey: "Fix Code and Get it Merged"

| Step | Action | Expected Result | Duration |
|------|--------|-----------------|----------|
| 1 | Push commit to feature branch | GitHub triggers CI workflow | 5 sec |
| 2 | CI runs lint + build + tests | PR shows status checks (🟢 passing, 🔴 failing) | 3-5 min |
| 3 | Developer reviews PR comments | Sees coverage diff + any lint errors | 1 min |
| 4 | Developer fixes issues | Pushes fixes, CI reruns automatically | 2 min |
| 5 | Merge approved (all gates pass) | Merge button enabled, code lands on main | 1 click |

---

## 8. Non-Functional Requirements

| Category | Requirement | Target |
|----------|-------------|--------|
| **Performance** | CI pipeline completes | <10 min per PR |
| **Reliability** | Build gates don't have false positives | <5% false positive rate |
| **Security** | All sensitive data redacted | 100% redaction (0 leaks) |
| **Compliance** | Logs suitable for audit | No tokens/emails/API keys anywhere |
| **Scalability** | Supports team growth | Works for 2-5 developers per project |

---

## 9. PRD → Spec Mapping

| PRD Requirement | Satisfied In Spec |
|-----------------|------------------|
| R1: Lint + type-check | Section 2.1, Epic 1, Issue 1.1 |
| R2: Run tests on PRs | Section 2.1, Epic 1, Issue 1.1 |
| R3: Coverage diff in comments | Section 2.2, Epic 1, Issue 1.2 |
| R4: Block on failures | Section 2.1, Epic 1, Issue 1.3 |
| R5: Redact sensitive data | Section 3.1, Epic 2, Issue 2.1 |
| R6: Track code complexity | Section 4.2, Epic 4, Issue 4.3 |

---

## 10. Out of Scope (v1.6.7)

- Machine learning-based bug prediction
- Custom lint rules per project
- Integration with non-GitHub platforms
- Mobile app for PR reviews
- AI-powered code generation suggestions

---

## 11. Success Criteria

### Product-Level Success
- ✅ CI pipeline active on 100% of PRs
- ✅ Coverage reports visible in GitHub (no login required to see badges)
- ✅ Branch protection prevents direct pushes to main/dev
- ✅ Zero security incidents from exposed sensitive data
- ✅ <5% false positive rate on build gates

### Team-Level Success
- ✅ Every PR has automated code review comments
- ✅ All developers understand CI failure modes
- ✅ Zero critical bugs to production (tracked over 90 days)
- ✅ Complexity of critical functions reduced 65%

### Business-Level Success
- ✅ Enterprise customers can point to "QA infrastructure" as compliance feature
- ✅ Support tickets for "regression bugs" drop by 50%
- ✅ Team confidence in releases increases (measured via survey)

---

## 12. Timeline & Milestones

| Week | Milestone | Deliverable |
|------|-----------|-------------|
| **Week 1** | Deploy CI infrastructure | .github/workflows/ci.yml, codecov.yml |
| **Week 1-2** | Secure logging foundation | scripts/core/logger.ts, 10 files migrated |
| **Week 2-3** | Establish testing baseline | 35%+ coverage, 6 test files created |
| **Week 3-4** | Refactor critical code | 23 → 8 critical functions, 70%+ coverage |

---

## 13. Dependencies & Risks

### Dependencies
- [BRD: Business Goals](../brds/qa2-brd.md#3-business-goals) - Defines success metrics
- Jest configuration (already complete)
- GitHub Actions availability

### Risks
- **Timeline compression:** 4 weeks is tight for 42-62 hours of work → Parallelize epics
- **Developer adoption:** Teams may ignore QA gates → Make gates configurable, educate
- **Coverage gaps:** New code may not have tests → Enforce test requirements in PR template

---

## 14. Next Steps

1. **Approve PRD** - Confirm product requirements and user journey align with BRD
2. **Generate Spec** - Technical implementation details and issue breakdown
3. **Run /scope-release** - Create GitHub issues from spec (10 issues across 4 epics)
4. **Start Sprint** - Begin Epic 1 implementation

**Document Status:** Ready for product review and approval
