- [Registry](https://stackfoundry.dev/registry): Catalog of modules, presets, provider adapters, and registry families.
- [Registry Index](https://stackfoundry.dev/r/registry.json): Machine-readable registry index for StackFoundry source modules.

## Machine-Readable Surfaces

## Notes For Automation

- The registry is the product; presets are only bundles of modules.
- Modules install source files, docs, env notes, checklists, and maintenance skills.
- Provider modules are adapters, not base dependencies.
