What is the scope of the rule that a non-Jew prohibits use of the mavoy — does the non-Jew prohibit only when his courtyard opens into the mavoy, or even when his courtyard opens into a Jewish courtyard (creating courtyard-to-courtyard access without foot-traffic through the mavoy)?

In a mavoy (alleyway) where one side is occupied by non-Jews and the other by Jews, and a second Jewish house opens to the public domain (not the mavoy) with only a window connecting it to the Jewish house in the mavoy — may the mavoy resident merge an eruv through that window to carry his belongings through his neighbor's house into the mavoy?

In a mavoy with Jews on one side and non-Jews on the other, if the Jewish courtyards made an eruv with each other through windows (or doorways) connecting the courtyards — may they carry through the mavoy via their doors opening into the mavoy, or must they first rent rights from the non-Jewish residents?

If a non-Jewish courtyard is situated between two Jewish courtyards in a mavoy, and the non-Jewish courtyard does not open into the mavoy and has no opening or window below ten tefachim to either Jewish courtyard — does the non-Jewish courtyard prohibit the Jewish courtyards from merging an eruv and using the mavoy?

When a non-Jewish courtyard intervenes between two Jewish courtyards (each with independent access to the reshut harabim or mavoy), may the two Jewish courtyards merge an eruv through connecting doorways and carry through the non-Jewish courtyard?

Does the concern about a Jew being alone among non-Jews (yachid b'makom akum) apply differently depending on whether the connection to the neighbor is via a window versus a full doorway?

Must the mavoy itself be properly configured (with a lechi, korah, or tzurat hapetach) for the eruv rules of siman 390 to apply?

According to the Rambam's formulation, is the prohibition in a mixed mavoy (Seif 2) more lenient or more stringent than the ruling in Seif 1 (as understood by Rashi/Tur), and are the two seifim in Shulchan Aruch consistent with each other?
