Current Task

Review and refine:

docs/02-architecture/SPRINT3_EXECUTION_GUIDE.md

This is an editorial review only.

Do NOT implement code.

Do NOT modify Sprint 3 Planning.

Do NOT create Sprint 3 Prompt Library.

Do NOT change the approved architecture.

Do NOT introduce new governance.

The objective is to polish the execution guide before it becomes the official Sprint 3 implementation handbook.

Mandatory References

Governance

- AI.md v1.1
- AI_DEVELOPMENT_SYSTEM.md
- WORKFLOW.md

Architecture

- ADR v1.0
- DBP v1.1
- SPRINT3_PLANNING.md

Previous Guides

- SPRINT1_EXECUTION_GUIDE.md
- SPRINT2_EXECUTION_GUIDE.md

Use Sprint 2 Execution Guide as the editorial baseline.

---

Perform the following review.

==================================================
1. Markdown Link Review
==================================================

Search for any local filesystem links such as:

file:///

Replace them with plain document references.

Example:

SPRINT3_PLANNING.md

Do not use local absolute paths inside repository documentation.

---

==================================================
2. Controller Rule Refinement
==================================================

Review the Service Layer section.

If wording such as:

"Controllers must be under 20 lines"

exists,

replace it with architecture-oriented wording.

Preferred guidance:

- Controllers remain thin.
- Controllers contain no SQL.
- Controllers contain no business rules.
- Methods should remain focused and cohesive.

Avoid prescribing arbitrary line-count limits.

---

==================================================
3. WorkspaceMiddleware Clarification
==================================================

Expand the WorkspaceMiddleware rules.

Explicitly state:

WorkspaceMiddleware:

- validates boundaries only
- never provisions workspaces
- never evaluates phases
- never mutates workspace state
- remains completely stateless

This is an editorial clarification.

No architectural change.

---

==================================================
4. Transaction Ownership
==================================================

Clarify transaction ownership.

Document that:

WorkspaceService owns the transaction.

Nested transactions are prohibited unless a future DRP explicitly introduces them.

WS-002 and WS-003 must never open provisioning transactions.

---

==================================================
5. Security Checklist
==================================================

Add one verification item:

No cross-workspace data leakage is possible.

This reinforces the Workspace Boundary Principle already approved in Sprint 3 Planning.

---

==================================================
6. Implementation Review
==================================================

Expand the review checklist.

Require reviewers to verify:

Workspace isolation

Cross-workspace access prevention

Workspace boundary validation

in addition to syntax and security checks.

---

==================================================
7. Quality Gates
==================================================

Add one Quality Gate.

Before implementation is considered complete:

Workspace isolation has been verified.

No tenant boundary violations detected.

---

==================================================
8. Sprint Exit Criteria
==================================================

Clarify implementation units.

Replace wording implying:

"3 tasks"

with the actual Sprint execution units:

- WorkspaceMiddleware
- WS-001
- WS-002
- WS-003

to match the Sprint 3 Planning document.

---

==================================================
9. Consistency Review
==================================================

Perform a complete editorial consistency review.

Verify:

- numbering
- terminology
- headings
- section hierarchy
- cross references
- workflow order
- middleware naming
- workspace terminology
- security wording

Correct editorial inconsistencies only.

---

Output

Provide:

1. Editorial Improvements
2. Security Clarifications
3. Governance Changes (if any)
4. Architecture Changes (if any)
5. Consistency Corrections
6. Final Recommendation

If no architectural issues remain:

Status:
FINAL

Version:
1.0 (Final)

Ready for:
SPRINT3_PROMPT_LIBRARY.md

Do not continue to Prompt Library.

Wait for Human Approval.
