CBDDC/docs-fix-batch-6.md

You are a C# documentation expert. Fix the following XML documentation issues in the listed files.

IMPORTANT: Make ONLY documentation changes. Do NOT modify code logic, behavior, signatures, or formatting unrelated to XML docs.

Model requirement: GPT-5.3-Codex-Spark Reasoning level: medium

Issue handling rules:

• MissingDoc: add concise XML docs with
  (and where appropriate)
• MissingInheritDoc: use /// for overrides/interface implementations where appropriate
• MissingParam: add missing ... tags
• MissingTypeParam: add missing ... tags
• MalformedXml: repair XML syntax and invalid tags

Preserve local style and keep descriptions concise.
