+    section 8 (revision 2, sha256 1b31e1d2…, Dewey's uncommitted working
+    file). The case: a board read that began before the broker's own move
+    is written, because its digest differs, and it then becomes the
+    latest snapshot. So `tasks_open` shows the old bucket until the next
+    tick. Dewey's check confirmed it against schema v3a.
+    - The poller keeps writing the row. A snapshot records what Vikunja
+      returned, and dropping one to make a view right would thin the
+      evidence.
+    - The schema decides what "current" means, once, for every reader. A
+      v3b amendment adds a view of each task's current snapshot. It skips
+      a `poll` row whose `read_at` is at or before the task's latest
+      `self` snapshot, and `tasks_open` is built on that view. The Q1
+      module, the CLI and the WebUI read the view and don't reimplement
+      the rule. Darkwing writes v3b, with a mutant that drops the rule.
+    - Dewey's Q3 correction also stands: the trail joins a task to its
+      request through `task.created`'s `request`, not through `subject`
+      on the `human.input` event.
