-# verstak-official-plugins
+# Verstak Official Plugins
 
-Official Verstak plugins monorepo — files, trash, notes, markdown-editor, preview, activity, journal, todos, browser-inbox, search, secrets, templates + shared packages.
+The first-party plugin set for Verstak Desktop: Files, Trash, Notes, editor and
+preview providers, Browser Inbox, Activity, Journal, Todo, Search, Secrets and
+Templates. Plugin bundles are built into independent directories that the
+desktop host loads from its `plugins/` folder.
 
-`Files` shows live workspace files and folders. Global `Trash` contains deleted items from every workspace; restoring never overwrites an existing item, and permanent deletion is confirmed before it runs.
+> **Alpha software.** Build this repository together with compatible
+> `verstak-desktop` and `verstak-sdk` checkouts.
+
+## Build
+
+Requirements: Node.js with npm, Go and Python 3. Keep this repository next to
+`verstak-sdk` so manifest validation can use the SDK schema.
+
+```bash
+npm --version
+go version
+./scripts/check.sh
+./scripts/build.sh
+```
+
+The build creates `dist/<plugin-id>/` packages. To install them into a sibling
+desktop checkout:
+
+```bash
+cd ../verstak-desktop
+./scripts/install-dev-plugins.sh
+```
+
+## Portable plugin archives
+
+Build target-specific archives on Linux:
+
+```bash
+sudo apt install gcc-mingw-w64-x86-64
+./scripts/package-portable.sh v0.1.0-alpha.1
+```
+
+The command creates `release/verstak-official-plugins-linux-amd64-<version>.tar.gz`
+and `release/verstak-official-plugins-windows-amd64-<version>.zip`, plus
+`SHA256SUMS`. Each archive expands directly into the desktop application's
+`plugins/` directory. Frontends and manifests are shared; native Go sidecars
+are built for the target OS. This is a local package operation and does not
+create a GitHub Release.
+
+## Alpha behaviour
+
+- Browser Inbox archives processed captures and can restore them; permanent
+  deletion is a separate action.
+- Saving a browser link creates a collision-safe `.url` file. Opening a link is
+  handled by Verstak, so it does not depend on a Linux `.url` file association.
+- Activity sessions can be scoped to a durable workspace identity or to an
+  explicit unassigned scope. Journal creation is always a user action.
+- Todo is optional: Overview uses it only when the Todo capability is present.
+
+## Publish a GitHub Release
+
+```bash
+./scripts/publish-github-release.sh v0.1.0-alpha.1
+```
+
+The publisher requires an authenticated [`gh`](https://cli.github.com/) CLI
+and a clean, up-to-date `main`. It runs the local release command, creates and
+pushes an annotated tag if necessary, then creates or updates the GitHub
+Release with the Linux archive, Windows archive and `SHA256SUMS`. Alpha, beta
+and release-candidate tags are published as prereleases; stable tags are
+marked latest. Re-running it for a tag that points at the current commit
+replaces the release assets.
