 Search indexes only published revisions and always requires provider reauthorization before returning a result. Generic public documentation generation reads static manifest topics only, so it cannot include tenant semantic entries. The separately authorized tenant export includes current entries and immutable history and sends `private, no-store`.
 
+Collection/context projection and search authorization load required revisions
+in request-local batches of at most 400 identifiers. Read-only projection loads
+published content only, never pending draft bodies, and remains available if a
+pending draft reference is broken. Editors still receive an explicit error for
+an unavailable current revision. Revision tenant, entry, and publication-state
+references must agree before content is projected or indexed. An audience
+denial is checked before calling the subject provider; an allowed audience does
+not replace the provider's current permission checks.
+
+This reduces Docs-owned database round trips without caching authorization
+between requests or importing subject-module internals. Owner-provider reads
+remain independent. The batch size is not a collection or export limit: complete
+semantic catalogues and separately authorized history exports can still require
+work proportional to their size.

 ## Backup, recovery, and module removal
 
 Back up `docs_semantic_entries` and `docs_semantic_revisions` together with Core tenant and audit state. Restoring only one table breaks revision pointers and is unsupported. The installer blocks normal uninstall while rows remain. Destructive retirement is explicit, requires a database snapshot, and drops revision history before entries.
