-The active `@contextualwisdomlab/cwl-editor/markdown` work in PR #114 is governed by Proposed ADR 0020. Its purpose is dependency isolation, not a second serializer authority. Until that PR or a verified successor integrates, the proposed subpath is unshipped and the protected root package remains the public authority for those serializers.
+Protected `main` includes the framework-independent `@contextualwisdomlab/cwl-editor/markdown` subpath under Accepted ADR 0020. It isolates dependency topology without creating a second serializer authority: the root package and the subpath share the same deterministic serializer and URI/inline-image policy modules. Packed ESM, CommonJS, and strict-TypeScript consumers are required evidence that the subpath remains browserless and independent of React, TipTap UI, Yjs, network, credential, and model authority.
 
 A framework-independent subpath must prove its declared dependency boundary from the packed npm artifact under ESM, CommonJS, and strict TypeScript consumers. Source-level import shape alone is insufficient release evidence.
 
 ## Presentation and print authority
 
 Inkspan owns the CSS rules it ships for its editor. It does not own the operating system print spooler, printer, browser's pagination implementation, downstream PDF storage, or host disclosure policy.
 
-Protected `main` currently remains the stylesheet authority. Proposed ADR 0021 and active PR #116 define a CSS-only `@media print` boundary intended to:

-- preserve authored document structures and links;
-- use conservative paged-fragmentation hints; and
-- keep links distinguishable without relying on color alone.
