# Project Review — xwquery (REF_35_REVIEW)

**Company:** eXonware.com  
**Last Updated:** 08-Feb-2026  
**Producing guide:** GUIDE_35_REVIEW.md

## Purpose

Project-level review summary and current status for xwquery (multi-language query layer). Updated after full review per GUIDE_35_REVIEW.

---

## Maturity Estimate

| Dimension | Level | Notes |
|-----------|--------|------|
| **Overall** | **Alpha (Medium)** | Many grammars/strategies; executors (core, aggregation, graph, etc.); parsers |
| Code | Medium–High | 247+ files; executors under `runtime/executors/`; layout stable |
| Tests | Medium–High | 0.core, 1.unit, 2.integration, 3.advance; strategy tests; runner |
| Docs | Medium | REF_22_PROJECT, REF_13_ARCH, INDEX, REF_15_API, REF_51_TEST; _archive for legacy |
| IDEA/Requirements | Clear (or partial) | REF_22 (vision, executor strategy, Firebase query parity); REF_13 (boundaries); REF_12 optional |

---

## Critical Issues

- **Executor refactor (align tests/docs).** Ensure tests and docs reference **current** executor layout only: `runtime/executors/` and subpackages (core, aggregation, filtering, data, graph, array, ordering, projection, advanced). No orphan references to removed paths. Document executor strategy and stability in REF_22_PROJECT and REF_13_ARCH (done). Remaining work: align tests and docs with current executor layout; no orphan references.

---

## IDEA / Requirements Clarity

- **Clear (or partial).** REF_22_PROJECT exists: vision, query languages, Firebase Firestore–style query parity, executor roadmap. REF_13_ARCH exists: parsers, strategies, executors, engine, stable vs evolving boundaries. Optional: REF_01_REQ (sponsor requirements), REF_12_IDEA (explicit idea context).

## Missing vs Guides

- REF_22_PROJECT.md — present.
- REF_13_ARCH.md — present.
- REF_35_REVIEW.md (this file) — present.
- docs/logs/reviews/ and REVIEW_*.md — present.
- Alignment of tests and docs with current executor structure (`runtime/executors/`) — in progress / ongoing.

## Next Steps

1. ~~Add docs/REF_22_PROJECT.md (vision, grammar/executor roadmap, Firebase query parity).~~ Done.
2. **Stabilize executor layout and align tests/docs.** All executor references must point to `runtime/executors/`; fix broken imports; update or remove obsolete doc references. No orphan references to deleted executor modules.
3. ~~Add REF_13_ARCH.~~ Done.
4. ~~Add REVIEW_*.md in docs/logs/reviews/.~~ Present.
5. ~~Add docs/INDEX.md.~~ Done. Executor strategy and stability documented in REF_22_PROJECT and REF_13_ARCH.
