ShopAssist resolves e-commerce support tickets into an action, a cited policy article, and (for the copilot path) a customer reply. Its two product workflows share ticket/order loading and a simulated LLM: Q1 builds one compact prompt and validates the response; Q2 triages deterministically, retrieves articles with BM25, composes once, then audits the draft. The README also documents the five policy cases and cost accounting. Edges reflect excerpts or README statements; the data directories are represented at their exact tree paths.
