Indexed from public GitHub and served as immutable, content-addressed versions.

The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Engineering Patterns Thirteen hard-won pattern guides for building tools and services, behind one catalog entry. Each guide is a **reference file** — read only the one that matches the problem in front of you, not the whole set. ## Pick the reference | If you are... | Read | |---|---| | Packaging a CLI — one-line install via `uv`/`npm`, subcommand dispatch, 3-tier config resolution | `references/cli-packaging-patterns.md` | | Writing a curl-piped installer for a stack that can't use `uv tool install`/`npm publish` | `references/one-line-installer-patterns.md` | | Persisting config and state — defaults merging, atomic crash-safe writes, XDG locations | `references/config-state-patterns.md` | | Building an HTTP service — FastAPI lifecycle, background poll loops, SPA + API proxy, WebSocket relay, SSE | `references/http-service-patterns.md` | | Adding auth or TLS — localhost bypass, token auth with auto-generation, automatic certificates | `references/auth-tls-patterns.md` | | Making processes talk through the filesystem — JSONL event logs, atomic snapshots, async request/response, SSE from file tailing | `references/file-ipc-patterns.md` | …
