Unclaimed disclosures in a published patent application and an earlier application it relies on for priority enter the public domain and thus become prior art as of the earlier application's filing date

question presented is: Do unclaimed disclosures in a published patent application and an earlier application it relies on for priority enter the public domain and thus become prior art as of the earlier application’s filing date, or, as the Federal Circuit held, does the prior art date of the disclosures depend on whether the published application also claims subject matter from the earlier application? @
