+# PersonalBlog (EPPP)
+
+A modular personal blogging platform. This is the **workspace bootstrap**
+(E00-S01): a pnpm monorepo skeleton with strict TypeScript, a committed frozen
+lockfile, and an enforced dependency boundary between core packages and
+concrete extensions.
+
+## Toolchain (pinned)
+
+| Tool         | Version      | Where pinned                                  |
+| ------------ | ------------ | --------------------------------------------- |
+| pnpm         | 11.23.0      | `packageManager` in root `package.json`       |
+| Node.js      | 24.x line    | `engines.node` in root `package.json`         |
+| TypeScript   | 6.0.3 (exact)| root `devDependencies`                        |
+| Vitest       | 4.1.10 (exact)| root `devDependencies`                       |
+
+Direct toolchain dependencies are exact-pinned; the lockfile is committed and
+installs always use `--frozen-lockfile`.
+
+## Workspace layout
+
+```
+apps/          application shells (e.g. server, admin)
+packages/      core / shared packages (contracts, core, extension-sdk, ...)
+extensions/    concrete extensions (themes, features, integrations)
+tests/         root-level architecture guard tests
+```
+
+Each group is a separate workspace glob in `pnpm-workspace.yaml`, so packages
+cannot accidentally collapse into one another.
+
+## Dependency boundary (FIT-001)
+
+Core packages (`packages/*`) must **never** import a concrete extension
+(`extensions/*`) — neither by package name nor by relative path. The rule is
+enforced by `tests/architecture.test.ts`, which discovers extension packages
+from the filesystem, so new extensions are guarded automatically. It runs as
+part of `pnpm test` and CI.
+
+## Local (non-container) developer path
+
+No Docker required for workspace work; containers arrive in E00-S02.
+
+1. Install Node.js 24.x (e.g. via nvm: `nvm install 24`).
+2. Enable the pinned package manager:
+   `corepack enable` (reads `packageManager: pnpm@11.23.0`), or
+   `npm install -g pnpm@11.23.0`.
+3. Install dependencies (frozen lockfile):
+   `pnpm install --frozen-lockfile`
+4. Verify the workspace:
+
+   | Command         | Runs                                                |
+   | --------------- | --------------------------------------------------- |
+   | `pnpm build`    | compiles every workspace package                    |
+   | `pnpm test`     | runs the test suite (Vitest, incl. FIT-001)         |
+   | `pnpm typecheck`| typechecks root tests and every workspace package   |
+
