+# AI Codex / Zastava Companion
+
+## Status
+NOT_FOUND
+
+## Description
+The advisory AI module exists with policy studio and LatticeRuleGenerator, but the specific "AI Codex" or "Zastava Companion" branding/feature set described in the advisory is not found.
+
+## Why Not Implemented
+- The specific "AI Codex" or "Zastava Companion" branding is not found, but substantial AI infrastructure exists:
+  - `src/AdvisoryAI/` provides evidence-anchored explanation generation with `EvidenceAnchoredExplanationGenerator`, `ExplanationPromptTemplates`, replay golden tests, and a web service (`AdvisoryAI.WebService/Program.cs`)
+  - `src/Zastava/StellaOps.Zastava.Observer/` exists as a runtime observer module
+  - The Web UI has Ask Stella components under `src/Web/.../shared/components/ai/`
+- The "AI Codex" concept (a comprehensive AI assistant branded as "Zastava Companion") appears to be a product vision not yet realized as a unified feature, though its constituent parts (AI explanations, policy studio, LatticeRuleGenerator) exist separately
