# Spec

Build a source-independent local RAG chat app with:

- Ollama-compatible streaming chat provider adapter;
- deterministic no-network provider test double;
- SQLite/libSQL-compatible durable conversations, documents, chunks, citations, memory, and settings;
- document upload/URL indexing and retrieval-augmented citations;
- memory/settings lifecycle controls;
- repeatable browser/e2e proof and evidence-ledger rows.

Status remains PROOF_REQUIRED until proof gates pass.
