---

Required Review Areas

1.

Executive Summary

Summarize Sprint 2 deliverables.

Confirm whether Sprint objectives were achieved.

---

2.

Architecture Assessment

Evaluate:

- Layer separation
- Service Layer
- Middleware architecture
- Authentication flow
- Session lifecycle
- Password reset lifecycle
- Routing
- Security boundaries

Confirm whether Sprint 0 kernel remains intact.

---

3.

Security Assessment

Review:

- password_hash()

- password_verify()

- random_bytes()

- hash_equals()

- CSRF enforcement

- Session regeneration

- Session destruction

- Output escaping

- Flash handling

- Role authorization

- Timeout enforcement

- Logging

Identify any weaknesses.

---

4.

Technical Debt Register

Review previous TD items.

Identify:

Resolved

Deferred

New

For every item provide:

- ID

- Description

- Severity

- Recommended Sprint

---

5.

Architecture Findings

Review implementation findings.

Include:

Resolved

Outstanding

Future considerations

Distinguish findings from technical debt.

---

6.

Documentation Review

Determine whether implementation remains consistent with:

ADR

DBP

MIB

Sprint Planning

Execution Guide

Prompt Library

Document any approved implementation clarifications.

---

7.

Conflict Review

Review:

AUTH-001 conflict

AUTH-004 conflict

Determine:

Were they correctly handled?

Did governance work?

Is a DRP required?

---

8.

Sprint Acceptance

State clearly:

Accepted

Accepted with Observations

Rejected

Provide reasoning.

---

9.

Recommended Next Step

Recommend only one:

Proceed to Sprint 3

Produce DRP

Synchronize documentation

Other

---

10.

Lessons Confirmed

Review governance itself.

Confirm lessons learned from Sprint 2.

Examples:

- Kernel freeze respected

- Conflict protocol effective

- Prompt Library sufficient

- Planning accuracy

- Documentation quality

- AI governance effectiveness

---

11.

Out of Scope

List items intentionally deferred.

Examples:

- CSP

- Log rotation

- Parameterized middleware

- Module-local view support

- Google Fonts localization

---

Output Requirements

Produce only:

SPRINT2_ARCHITECTURE_REVIEW.md

Include:

Version

Status

Date

Architecture Scorecard

Technical Debt Register

Architecture Findings

Governance Review

Sprint Verdict

Final Recommendation

---

Rules

Do NOT modify implementation.

Do NOT rewrite code.

Do NOT synchronize documents.

Do NOT produce DRP.

Only recommend whether a DRP is required.

---

Final Recommendation

Conclude with exactly one recommendation:

- Sprint 2 Closed — Proceed to Sprint 3

OR

- Sprint 2 Closed — Synchronize Documentation

OR

- Sprint 2 Closed — Produce Design Revision Pack

Provide clear justification.
