capsite: checklist: 1g, notes on public items are public too

The public cache keeps public items whole, private annotations and
comments included (2,525 of 14,645). Dan finds that acceptable; the
goal is to finish thinking it through, not to fix a leak.

+        whole, including annotations, comments, and sticky notes that
+        diigo marks private (`pri_a_count`/`pri_c_count`/

+        finds this acceptable as is**; this goal is to finish thinking
+        it through, not to fix a leak. Open points: does diigo.com's
+        own public view hide them (so readers are surprised)? the
+        `comments` array may carry *other people's* words; which fields
+        does potluck quote (annotations are the best commentary: see
+        [the issues sketch](potluck/issues-sketch.md))? If the policy
