They let a view react to who is viewing it, for example by offering a \"retract\" action only on rows the viewer signed.</p>
<p>Declare them as optional multi-value placeholders, each with its own empty values block in every scope where it is used: <code>?__LOCALPUBKEY_multi</code>, <code>?__CURRENTUSER_multi_iri</code>, <code>?__SITEURL_multi</code>.</p>
<p>A logged-out visitor has none of them, so the variable is simply unbound and every comparison must tolerate that. Wrap each one in <code>coalesce</code>, as in <code>coalesce(str(?pubkey) = str(?__LOCALPUBKEY_multi), false)</code>, so the query still returns its rows instead of failing or dropping them.</p>""";
