The process is supervised: on exit after a successful initialize it is spawned again with exponential backoff (500ms to 30s), open documents are re-sent as didOpen before the new session is announced, and requests caught by the crash wait for it and retry. A crash more than a minute after the previous one starts a fresh streak; reaching the streak limit (default 3) ends restarting for good, after which every request fails with an LspError saying so. Restarts and give-ups are logged and forwarded to the MCP client. Writes to the child's stdin go through a PassThrough so a broken pipe ends the session instead of surfacing as an unhandled rejection.
