mcp.shared.session in mcp: withdrawn
This correction was withdrawn on 2026-10-21: fix replaces the removed BaseSession check with an isinstance check against ClientSession itself, which is always true: it hides the change instead of migrating (manual review 2026-10-21).
It is kept here so that links to it keep working. Every withdrawal, merge and recheck is listed in the changelog.
