This checked-in Open Knowledge Format bundle explains Kast through stable concepts backed by repository sources. It is designed for progressive disclosure: choose a category, read one concept, and open the cited source only when implementation detail is necessary.
## Start here
- [Modules](modules/index.md) — ownership and dependency boundaries. - [Runtime flows](flows/index.md) — how requests and state move through the system. - [Contracts](contracts/index.md) — invariants that callers and adapters must preserve. - [Glossary](glossary/index.md) — terms with repository-specific meaning. - [Update log](log.md) — meaningful knowledge-base changes.
## Reading order
1. Read the governing `AGENTS.md` for durable engineering rules. 2. Use a category index to select one concept. 3. Follow concept links to adjacent concepts before opening implementation. 4. Use `code_sources` and inline source links for authoritative details. 5. Run the impact command after source ch
