RAG in Production — Blog Draft (archived)

Blog post draft on RAG. Plan was to publish to vectorbuilds.dev. Killed in revised plan (no blog work until post-offer). Original draft existed at Project_2026/Blog/RAG in Production Draft.md — see git history for content if needed.

Why archived

All weekly trackers above were built on the old Mar 18 → Sep 18 plan numbering. Revised plan starts May 11, 2026 = W1 (validation gate). Old W07 = new W1, W08 = new W2, etc. — but content tracks (Tries / FastAPI / LLD / Backend project / RAG SD problem) don't match revised single-track focus (NeetCode + SD + behavioral + apply only).

Revised plan source of truth: Private/Project_2026/Coach/ — auto-updates per session.
