**Company:** eXonware.com  
**Last Updated:** 07-Feb-2026  
**Producing guide:** GUIDE_35_REVIEW.md

---

## Purpose

Project-level review summary and current status for xwnode (graph-based data engine). Updated after full review per GUIDE_35_REVIEW. Downstream REFs aligned with REF_01_REQ.

## Maturity Estimate

| Dimension | Level | Notes |
|-----------|--------|------|
| **Overall** | **Alpha (High)** | ~88%; 57+ node strategies, 28+ edge strategies, 35+ query langs; WAL, Bloom, atomic CAS |
| Code | High | 174+ files; strategies, engines, benchmarks |
| Tests | High | 4-layer; 100+ test files |
| Docs | High | REF_01_REQ, REF_11_COMP, REF_12_IDEA, REF_13_ARCH, REF_14_DX, REF_15_API, REF_21_PLAN, REF_22_PROJECT, REF_35_REVIEW, REF_51_TEST, REF_54_BENCH; architecture, benchmarks, changes, logs/reviews/ |
| IDEA/Requirements | **Clear** | REF_01_REQ complete (14/14); REF_11, REF_12, REF_13, REF_14, REF_15, REF_21, REF_22 present and sourced from REF_01_REQ |

## Critical Issues

- **None blocking.** Root .md (INSTALL_DEPS, MIGRATE_FEATURE_VERIFICATION) moved to docs/_archive per GUIDE_41_DOCS; value extracted to REF_22 and REF_13 (07-Feb-2026). _archive contents consolidated to REFs and logs (07-Feb-2026); see [REVIEW_20260207_ARCHIVE_CONSOLIDATION.md](logs/reviews/REVIEW_20260207_ARCHIVE_CONSOLIDATION.md).

---

## IDEA / Requirements Clarity

- **Clear.** REF_01_REQ is the single source (14/14 clarity). REF_12_IDEA, REF_13_ARCH, REF_14_DX, REF_15_API, REF_21_PLAN, REF_22_PROJECT are present and populated from REF_01_REQ. Traceability: REF_01_REQ → REF_12, REF_22, REF_13, REF_14, REF_15, REF_21.

## Missing vs Guides

- REF_01_REQ.md — present; complete.
- REF_11_COMP.md — present; compliance stance from REF_01_REQ sec. 4.
- REF_22_PROJECT.md — present; source REF_01_REQ; vision, goals, FRs, NFRs, milestones, traceability.
- REF_13_ARCH.md — **Present;** requirements source REF_01_REQ; boundaries, layering, delegation, XWQuery integration.
- REF_15_API.md — **Present;** requirements source REF_01_REQ sec. 6.
- REF_35_REVIEW.md (this file) — **Updated.**
- REF_12_IDEA, REF_14_DX, REF_21_PLAN — **Present;** filled from REF_01_REQ (07-Feb-2026).
- docs/logs/reviews/ and REVIEW_*.md — Present.
- **Gap (docs/code/tests/examples/benchmarks):** [REVIEW_20260207_120000_000_GAP_DOCS_CODE_TESTS_EXAMPLES_BENCHMARKS.md](logs/reviews/REVIEW_20260207_120000_000_GAP_DOCS_CODE_TESTS_EXAMPLES_BENCHMARKS.md).

## Next Steps

1. ~~Add docs/REF_22_PROJECT.md (vision, FR/NFR, milestones).~~ Done; sourced from REF_01_REQ.
2. ~~Add docs/REF_13_ARCH.md (strategies, engines, boundaries).~~ Done; sourced from REF_01_REQ.
3. ~~Update REF_35_REVIEW (IDEA/Requirements, Missing vs Guides).~~ Done.
4. M4 — XWQuery support without circular ref; xwdata/xwentity/xwschema/xwaction support (pending).
5. Consider Beta after extended production use.
6. ~~Add REF_12_IDEA, REF_14_DX, REF_21_PLAN.~~ Done (07-Feb-2026).
