+# Architecture
+
+## Three layers
+
+### 1) Raw sources (`../raw/`)
+- Curated, **immutable** source documents.
+- Articles, papers, transcripts, images, datasets.
+- The “source of truth”.
+
+### 2) Wiki layer (`./`)
+- LLM-maintained markdown pages: summaries, concept pages, entity pages, comparisons, synthesis.
+- This is what we query most of the time.
+- Updated incrementally as new sources arrive.
+
+### 3) Schema (conventions)
+- The rules that govern structure, naming, page types, and workflows.
+- In this repo, start with: [[05 NoxPKB/README]] (can evolve).
+
+## Why this architecture
+- Shifts work from repeated query-time synthesis to **one-time ingest + ongoing maintenance**.
+- Enables compounding knowledge via cross-links and curated pages.
+- Makes contradictions and gaps visible and actionable.
