# Active extension docs

These pages describe the ten entrypoints currently loaded by `package.json#pi.extensions`.

Source truth remains code-first:

- `package.json#pi.extensions` defines the default loadable surface.
- `extensions/<extension>/manifest.json` defines commands, tools, hooks, permissions, risk, state, review status, and docs/source-audit paths.
- These pages explain current behavior for humans. They do not promote beta code by themselves.
