LMP + MEDI Advanced RAG — Integration Spec

Goal: Build an advanced RAG sample showing how LMP (Language Model Programs) and MEDI (Microsoft.Extensions.DataIngestion) coexist and natively layer. MEDI handles pipeline infrastructure (ingestion, vector search, RRF, tree traversal). LMP handles the intelligence layer (optimizable typed predictors for every LLM call). LMP optimizers tune the whole thing end-to-end.

Domain: Survival/equipment documentation (matching the advanced-rag sample).

NixOS Copilot CLI Declarative Install Guide

Overview

This document describes a **declarative installation of the GitHub Copilot CLI** on NixOS (25.11).

This method creates a small local Nix package that:

• installs the Copilot CLI via npm
• works with NixOS’s dynamic linking model using nix-ld

PRD + Tech Spec — .NET NuGet “Model Fetch + Cache” System (HuggingFace default, configurable source, optional MSBuild prefetch)

1. Problem Statement

We ship a .NET NuGet package that uses an AI model. The model can be large (100MB–multiple GB). Putting the model inside the NuGet package is a bad fit (slow restore, duplicated storage per version, plan quotas, painful CI).

We need a robust, boring, predictable way to:
