What
For MCP servers connected over SSE, an error thrown by a close handler no longer escapes; it is logged and counted, so one bad handler cannot take down the shutdown path.
Details
The failure is reported as its own metric, cli_sse_close_handler_threw.
Two separate checks for whether the connection is going away, an abort signal and a state string comparison, were replaced by one helper.
Evidence
cli_sse_close_handler_threw
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
