# Registry Rules

`_system/registry.md` is the only visible project registry.

## Sections

- Sources
- Knowledge
- Experiments
- Results
- Writing
- Maps
- Archive

## Rules

- Every canonical note must have a registry entry.
- `Daily/` notes are not registered by default.
- Registry entries use stable IDs that do not depend on note titles.
- Archive keeps history; archiving does not delete registry history.
- Paths are rendered as wikilinks.
- The registry is machine-parsed from Markdown tables; do not create a second formal JSON registry.
