-## Project Overview
+## Repository Layout
 
-**CTBase.jl** is the foundational Julia package in the [control-toolbox](https://github.com/control-toolbox) ecosystem.
-It provides the **base layer**: shared types, exceptions, extensions infrastructure, and development tools.

-Submodule layout (all public symbols accessed via qualified paths — no top-level exports):
+Standard control-toolbox package structure. Each directory may contain a `README.md`

-## Essential rules
+Quick-reference for any agent working on this repository.
 
-1. **Never commit or push without explicit approval.** Ask first, every time.
-2. **Run tests via the `ct-dev-mcp` MCP** — `get_test_command` → run with `tee` →
-   `generate_report`. Never invent the test command.
-3. **Build docs draft-first** — `draft = true` globally to validate links, then per file
-   with `Draft = false`, then full build. See `dev/RULES.md`.
-4. **Qualify everything** — `Module.symbol` at every call site; `import Pkg: Pkg` not
-   `using Pkg`; no top-level package exports.
-5. **Write a plan before coding** — any task touching more than one file or a public
-   interface needs a plan confirmed by the user first. Template in `dev/planning.md`.
-6. **Docstrings last** — written only after the API is stable.
-7. **Fake types at module top-level** — never inside test functions (world-age issues).
