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 <summary> (and <returns> where appropriate)
- MissingInheritDoc: use /// <inheritdoc /> for overrides/interface implementations where appropriate
- MissingParam: add missing <param name="...">...</param> tags
- MissingTypeParam: add missing <typeparam name="...">...</typeparam> tags
- MalformedXml: repair XML syntax and invalid tags

Preserve local style and keep descriptions concise.

Execution rules:
1. Read each file and apply all listed documentation fixes.
2. Keep changes minimal and doc-focused.
3. Avoid duplicate XML tags or malformed XML.
4. Return a short summary: files modified, issue count fixed per file, and any unresolved items.
