Bug fixes

• A Windows update no longer drops the organization's trusted proxy or certificate.
• The toolbar and guardian agent list report protection accurately again.

• A newly-seen coding agent is instrumented automatically, instead of being skipped until an administrator adds it.
• guardian doctor reports network and certificate problems more precisely, instead of pointing at the wrong cause.
• A credential Guardian couldn't verify now says so, instead of showing a blank dash
