+// `npm run check:community-group-links` writes `archived: null` /
+// `reachable: null` for a group whose recheck came back inconclusive -- a
+// network error, a rejected token, an API outage -- when no previous report
+// carries a known status forward. Both consumers read null as healthy on
+// purpose: scripts/check-community-group-links.mjs says so where it writes
+// the value, and scripts/validate-community-groups.mjs warns only on the
+// strict `=== true` / `=== false` comparisons.
+//
+// The filter here has to make the same distinction (`group.archived ||
+// group.reachable === false`), and nothing pinned it: every fixture in this
+// file and in tests/e2e/fixtures/** sets both fields to a boolean, so
+// relaxing the strict comparison to `!group.reachable` would keep the whole
+// suite green while telling readers that a group nobody could check is
+// archived or unreachable.
