"Proposed"; but a past participle ending often - in speech - gets mixed up with the next word. For example, when I was a child a publisher thought of the idea of selling three or four books all at the same time, and called it a 'boxed set'. In speech there is no word boundary: /bɒksʦet/. And the consonant cluster then gets simplified.

Today, even the spelling has caught up. Google gives these hits:

Results 1 - 10 of about 4,190,000 for "boxed set"
Results 1 - 10 of about 24,600,000 for "box set"

So "proposed schedule" has a medial /d/, but I wouldn't be surprised if some 22nd century linguist refers to the /d/ that 'used to be present in that phrase'.
