Project memory for the solo developer. One markdown-on-disk corpus tracking design docs, TDDs, and task notes across a portfolio, queryable through any LLM via MCP. See [docs/vision.md](docs/vision.md) for the longer "what + why + what we're explicitly not building." ```sh cargo install --path . mkdir -p ~/dossier-corpus/.dossier # the .dossier/ marker is all you need
