Under a multiplexer MCP tools are registered per profile overlay while the
server toolset alias is process-global, so a cron job naming a server in
enabled_toolsets that is connected only for another profile validated as a
known toolset, resolved to zero tools, and ran tool-less with quiet_mode
hiding the only diagnostic; the run was booked success (#109050).
After cron MCP discovery, an explicitly requested enabled MCP server that
resolves empty in this profile scope now takes the existing blocked_config
path (incident, alert-once, visible last_status). The implicit merge of
all enabled servers is not judged; only servers the job asked for.
