# Review: Archive consolidation — value extracted to REFs and logs

**Date:** 07-Feb-2026  
**Scope:** xwnode docs/_archive  
**Outcome:** All archived files reviewed; value moved to REF_22, REF_51, REF_54, REF_13, REF_15, REF_35, logs/project, logs/benchmarks_logs, and changes/. Archive files removed; only README remains in _archive.

---

## Summary

- **Production / status:** Production readiness 65/100 (Oct 2025), 51/51 strategies production-ready, security 60 (tests created; execution pending). Value → REF_22_PROJECT, logs/project/PROJECT_20251011_000000_000_PRODUCTION_READINESS.md (updated to remove _archive links).
- **Tests:** 4-layer suite (0.core–3.advance), 566/605 core tests (historical). Value → REF_51_TEST.
- **Benchmarks:** Baseline methodology (1k/100 iters, put/get/delete/size/iteration); LRU_CACHE 6800x improvement (path fix), cache infra and eviction phases. Value → REF_54_BENCH, benchmarks/20260321-benchmark xwnode consolidated/benchmarks/BENCH_20260207_ARCHIVE_BASELINE_AND_LRU.md.
- **Architecture / API:** Strategy list (64 node, 32 edge), design patterns, LRU_CACHE and cache strategies in docs. Value → REF_13_ARCH, REF_15_API (full API summary from legacy API_REFERENCE).
- **Install / migration:** Quick install and performance deps (numpy, scipy, scikit-learn). MIGRATE features verified in main library. Value → REF_22, GUIDE_01_USAGE.
- **Session / implementation summaries:** Session 1, refactoring, version comparisons, optimization reports. Value captured in this review and in REF_22/REF_35; change history in changes/ (CHANGE_20260208_ARCHIVE_CONSOLIDATION Phase 2).

## Key findings retained

1. **Production readiness (Oct 2025):** 65/100 overall; Security 60, Usability 85; 51/51 strategies production-ready; 566/605 core tests passing. Foundation complete; validation and security execution pending.
2. **LRU_CACHE performance:** Path navigation fix → 6800x (1576ms → 0.23ms); cache infrastructure and eviction optimizations followed. Baseline methodology: 1000 iters (nodes), 100 (edges), warmup 100/10.
3. **Strategy coverage:** 28+ node and 16+ edge strategies (Session 1); current REF_22 states 60+ node, 30+ edge. API_REFERENCE listed 64 node, 32 edge; REF_15 updated with same.
4. **Docs:** LRU_CACHE and cache strategies must be present in strategy docs (DOCUMENTATION_REVIEW_FINDINGS); REF_13 and REF_15 now reference cache strategies and full strategy list.
5. **Install:** `pip install exonware-xwsystem` then numpy/scipy/scikit-learn then exonware-xwnode (or `pip install -r requirements.txt`) to avoid xwlazy delays.
6. **Migration:** All MIGRATE features verified in main library (MigrationPlan, StrategyMigrator, registry, node/edge strategies).
