 - Source code: `src/` (CLI wiring in `src/cli`, commands in `src/commands`, web provider in `src/provider-web.ts`, infra in `src/infra`, media pipeline in `src/media`).
 - Tests: colocated `*.test.ts`.
 - Docs: `docs/` (images, queue, Pi config). Built output lives in `dist/`.
-- Plugins/extensions: live under `extensions/*` (workspace packages). Keep plugin-only deps in the extension `package.json`; do not add them to the root `package.json` unless core uses them.
+- Nomenclature: use "plugin" / "plugins" in docs, UI, changelogs, and contributor guidance. `extensions/*` remains the internal directory/package path to avoid repo-wide churn from a rename.
+- Plugins: live under `extensions/*` (workspace packages). Keep plugin-only deps in the extension `package.json`; do not add them to the root `package.json` unless core uses them.
 - Plugins: install runs `npm install --omit=dev` in plugin dir; runtime deps must live in `dependencies`. Avoid `workspace:*` in `dependencies` (npm install breaks); put `openclaw` in `devDependencies` or `peerDependencies` instead (runtime resolves `openclaw/plugin-sdk` via jiti alias).
 - Import boundaries: extension production code should treat `openclaw/plugin-sdk/*` plus local `api.ts` / `runtime-api.ts` barrels as the public surface. Do not import core `src/**`, `src/plugin-sdk-internal/**`, or another extension's `src/**` directly.
 - Installers served from `https://openclaw.ai/*`: live in the sibling repo `../openclaw.ai` (`public/install.sh`, `public/install-cli.sh`, `public/install.ps1`).
