@soeditor/plugin-sdk

Narrow package-root facade for SoEditor plugin authors. It re-exports public SoEditor-owned lifecycle, command, service, structured-editing, diagnostics, projection/layout, UI contribution, and FileManager contracts without exposing implementation registries or third-party library types.

The SDK includes generic diagnostics workflow types and the adapter/service contracts needed by alternate split-view integrations. Built-in accessibility and SEO rule configuration remains owned by @soeditor/html-tools; the built-in DOM layout factory remains owned by @soeditor/layout.

Structured block conversion contracts, the editor-owned registry token, and operation/position mapping are re-exported from their @soeditor/engine owner. Conversion callbacks use only SoEditor HTML values and cannot create editing DOM; see the repository plugin guide for a complete custom-element example. The experimental visual-decoration plugin, token, and immutable range types are also exposed for non-canonical annotation providers.

The SDK also curates the comments/revisions plugin factories, service tokens, immutable models, storage and permission contracts, review policy, and versioned export types. Concrete controllers, rendering internals, and adapter implementations remain in their owning packages.
