Resolved. The Apple software update that ran the other day changed something relating to Access Control Lists (ACLs). That somehow affected ACLs pertaining to internal disk home folder. Fix: with OSX install disk in, boot holding 'c' key down; choose Reset ACLs on menu; click reset button in ACLs dialog box; reboot. Amazing - Apple Tech Support called within 5 seconds of my clicking the "Call You Now" choice on their tech support page. Limited testing since ACLs reset shows resumption of normal OSX and calibre trashing behavior.

My apologies for initially assuming it was a calibre problem, and for possibly boring anybody by thinking out loud in this thread. But typing as I thought about it really helped me think about it. Knowing others might read what I typed made me think about the problem more carefully and thoroughly. So thank you for listening.
