Deterministic source record. The complete textual file is reproduced below; this page does not replace architectural interpretation in the authored chapters.
# Repository-local documentation
The **canonical ChrisOS documentation is https://os.christiansoftware.org/**.
This directory is intentionally small. It contains only instructions that must stay close to the repository because they describe how to work with the current source tree.
## Kept here
### Getting started
- [Development environment](getting-started/environment.md)
- [Build and run](getting-started/build-and-run.md)
### Development
- [Development workflow](development/workflow.md)
- [Testing and evidence](development/testing.md)
Also see [Contributing](../CONTRIBUTING.md) and [Security policy](../SECURITY.md).
## Not maintained here
Architecture, subsystem design, ABIs, implementation-status snapshots, hardware matrices, audits, campaign reports, plans, roadmaps, ChrisVM/ChrisCPU documentation, toolchain documentation and educational chapters belong in **https://os.christiansoftware.org/** and its source repository, `christianrss/chrisos_site`.
This avoids two competing documentation trees and prevents historical status files from being mistaken for the current state.
## Rule
If a change affects setup, build, run, test or contribution mechanics, update these repository-local guides.
If a change affects architecture, behavior, specifications, subsystem documentation, capability status or project direction, update **chrisos_site**.
The atlas guarantees file-by-file traceability. Responsibility, invariants, ownership, concurrency, security, performance and subsystem interactions belong in authored chapters and must cite this file when applicable.
