Approvals are a package now

Approval workflows used to be a compiled platform module (MeshWeaver.Approvals, listed under Modules:Assemblies) that registered a form, an inline section and a menu entry onto every per-node hub of the mesh. They now ship as the node-native Approvals package: two NodeTypes the mesh compiles live from their own Source/, with no assembly in the platform image and no restart to install or remove.

What changed for you

• Nothing, if you use approvals. The Request Approval entry, the inline approvals section on a document page, and the Approve / Reject views all work as before — provided the Approvals package is installed (it is pre-installed).
• The feature is now optional in the honest sense. Uninstalling the package removes the UI cleanly; installing it adds the UI immediately, with no image roll.
• Your data is untouched. Approvals are still {document}/_Approval/{id} satellites in the partition's annotations table. The Approval record and that mapping stay platform-level, so stored approvals keep deserializing and routing regardless of what is installed.

What made it possible

Two platform seams did the work the module used to do by force:

• A UiContribution node contributes the Request Approval menu entry as DATA (#1645). Its Href may now carry a {node} token, substituted with the node whose menu is rendered — so a contributed entry can open a surface the plugin serves from its OWN workspace, which is the only shape available to a package that cannot register an area onto another type's hub.
• The markdown overview probes and delegates. Instead of asking a configuration marker whether approvals are enabled, it asks the mesh whether the package's desk exists — one bounded query-index probe, the same shape the Versions page uses for the Collaboration package — and embeds the package's own area. No package, no section, no cost.

For content authors

MeshWeaver.Graph.ApprovalExtensions.AddApprovals() and the rest of the pre-extraction legacy surface are gone: nothing needs per-hub registration any more. In-mesh sources that still call it simply drop the call.
