social.x_deletions checks stored posts through the official API. A post X
reports as not found keeps a marked record (author, link, dates, Internet
Archive link if a copy exists) while every copy of its text is removed, as
the Developer Agreement requires. A post that shows up in the timeline again
is restored by the normal upsert.
mcp 2.x removed FastMCP, which crash-looped the MCP server on first deploy.
