# Review: Project/Requirements — xwschema (REF_01_REQ alignment)

**Date:** 07-Feb-2026 12:00:00.000  
**Artifact type:** Project/Requirements  
**Scope:** REF_01_REQ (xwschema) + code + tests + docs  
**Informed by:** PROMPT_01_REQ_03_UPDATE; REVIEW_20260207_PROJECT_STATUS.md; REF_35_REVIEW.md

---

## Summary

**Outcome:** Pass with comments. REF_01_REQ is complete (14/14 clarity) and Ready to fill downstream docs. Review finds alignment in most areas; gaps and plan below address (1) implementing existing REF_01_REQ content and (2) refreshing downstream REFs from REF_01_REQ.

---

## 1. Critical issues

| Finding | Location | Note |
|--------|----------|------|
| **None blocking.** | — | No inconsistent or conflicting requirements; no milestones contradicting REF_13_ARCH. |
| **Resolved** | REF_01_REQ sec. 2 Anti-goals | Sponsor clarified: use xwdata—it is the base of the engine. Anti-goal = do not reimplement or bypass xwdata. REF_01_REQ updated accordingly; code (imports of XWData/IData) is correct. |

---

## 2. Improvements

| Finding | Location | Suggestion |
|--------|----------|------------|
| REF_22 / REF_13 wording | REF_22_PROJECT, REF_13_ARCH | Align vision and goals with REF_01_REQ sec. 1–2 (sponsor voice, one-sentence purpose, scope, anti-goals). |
| REF_15_API | REF_15_API.md | Expand from placeholder; list main entry points and "easy vs advanced" from REF_01_REQ sec. 6. |
| Traceability | REF_22, REF_13 | Add "Produced from REF_01_REQ" and reference REF_01_REQ section numbers where applicable. |

---

## 3. Optimizations

| Finding | Location | Note |
|--------|----------|------|
| Redundant requirements | — | None. REF_01_REQ is single source; downstream REFs should derive, not duplicate verbatim. |
| REF_35_REVIEW "Missing" | REF_35_REVIEW.md | Update "No REF_22_PROJECT or REF_PROJECT" and "IDEA/Requirements Clarity" to reflect REF_01_REQ completion and REF_22/REF_13 presence. |

---

## 4. Missing features / alignment

| Gap | REF_01_REQ | Code/Tests/Docs |
|-----|------------|------------------|
| Downstream REFs not filled from REF_01_REQ | sec. 1–10 complete; Ready = Yes | REF_22_PROJECT and REF_13_ARCH exist but are brief; not explicitly fed from REF_01_REQ. REF_12_IDEA and REF_14_DX absent. REF_15_API minimal. |
| v1 DoD "100% tests" | sec. 9 Definition of done | Test layers 0.core–3.advance present; confirm 100% pass and coverage expectations documented (e.g. REF_51_TEST). |
| Success criteria in REF_22 | REF_01_REQ sec. 1 Success (6 mo / 1 yr) | REF_22 does not yet list 6 mo / 1 yr success; could add from REF_01_REQ. |

---

## 5. Compliance & standards

| Check | Result |
|-------|--------|
| Five Priorities | REF_01_REQ sec. 8 addresses Security, Usability, Maintainability, Performance, Extensibility. |
| GUIDE_22_PROJECT / REF placement | REF_* under docs/; REF_01_REQ follows GUIDE_01_REQ template. |
| GUIDE_00_MASTER | Docs under docs/; REF/LOG ownership respected. |

---

## 6. Traceability

| Link | Status |
|------|--------|
| REF_01_REQ → REF_22, REF_13, REF_15 | To be strengthened: downstream REFs should reference REF_01_REQ and be populated from it. |
| REF_22 → REF_01_REQ | Not stated; add "Requirements source: REF_01_REQ". |
| REF_13 → REF_01_REQ | Not stated; add "Requirements source: REF_01_REQ". |
| Code/tests → REF_01_REQ | Implicit (code implements use cases in sec. 5–6); no orphan code identified. |

---

## Implementation plan

Actions address **both** (1) implementing existing REF_01_REQ and (2) putting the "fill downstream docs" direction in place. Report (REVIEW_20260207_PROJECT_STATUS, REF_35_REVIEW) informed gaps.

### Priority 1 — Align downstream REFs

| # | Action | Owner | Note |
|---|--------|-------|------|
| 1.1 | Refresh REF_22_PROJECT from REF_01_REQ: vision (sec. 1), goals (sec. 1), scope (sec. 2), NFRs (sec. 8), milestones (sec. 9), risks (sec. 10). Add "Requirements source: REF_01_REQ". | Dev | Per PROMPT_01_REQ_03_UPDATE Step 2. |
| 1.2 | Refresh REF_13_ARCH from REF_01_REQ: sec. 7 architecture/tech, sec. 6 API boundaries, sec. 5 use cases. Add "Requirements source: REF_01_REQ". | Dev | |

### Priority 2 — Docs and traceability

| # | Action | Owner | Note |
|---|--------|-------|------|
| 2.1 | Expand REF_15_API from REF_01_REQ sec. 6: main entry points, easy vs advanced, integration, not in public API. | Dev | |
| 2.2 | Add REF_12_IDEA if project needs idea/context doc (GUIDE_12_IDEA); populate from REF_01_REQ sec. 1 (problem, vision). | Dev | Optional. |
| 2.3 | Add REF_14_DX if DX goals need a dedicated doc (GUIDE_14_DX); populate from REF_01_REQ sec. 5–6 (developer persona, key code). | Dev | Optional. |
| 2.4 | Update REF_35_REVIEW.md: set IDEA/Requirements to "Clear (REF_01_REQ 14/14)"; update Missing vs Guides and Next Steps. | Dev | |

### Priority 3 — v1 closure

| # | Action | Owner | Note |
|---|--------|-------|------|
| 3.1 | Confirm all test layers (0.core–3.advance) pass; document "100% tests" status (REF_51_TEST or REF_22). | Dev | REF_01_REQ sec. 9 DoD. |

---

## Next steps (suggested order)

1. **Dev:** Refresh REF_22 and REF_13 from REF_01_REQ (1.1, 1.2).  
2. **Dev:** Expand REF_15_API (2.1).  
3. **Dev:** Update REF_35_REVIEW (2.4).  
4. **Dev:** Confirm test pass and document (3.1).  
5. Optionally add REF_12_IDEA / REF_14_DX (2.2, 2.3) per project needs.
