we are very sorry you are experiencing problems with GPG Suite.
You can change that preference in System Preferences -> GPG Suite.
We found that the default makes it easier for users not yet familiar with GnuPG.
Thank you, that solved the issue. I wasn't aware that there was an associated system preference pane and couldn't find what I wanted in the keychain app's menus or settings. The preference pane also has a button to remove all stored passphrases, which easily solves the problem even retroactively.
Apologies for my berating tone in the original message. It mostly reflected pent up frustration with the untrustworthy tech infrastructure that led me to delve into GPG to begin with. Now that it's configured to my liking, this app suite is amazing.
