+60. **Schema v3b accepted, and the S3 poller compares against the
+    current snapshot (2026-10-04).** Source: Darkwing,
+    `agents/darkwing/work/slice1-proto/` at 48d76de7, `schema-v3b.sql`
+    sha256 179ffe35…, stored schema digest 52514a11…, notes in
+    `proto-v3b-notes.md`. Tables 8, triggers 36, views 5.
+    - The v3b change is one view, `task_current`, and `tasks_open` is
+      rebuilt on it. `diff schema-v3a.sql schema-v3b.sql` shows nothing
+      else. I reran `proto-v3b.mjs` on Node 26.8.1 on the host and on
+      Node 24 in the `node:24` image with no network. Both outputs match
+      Darkwing's recorded files byte for byte.
+    - S2 pins v3b instead of v3a. Rocko already has the change from
+      Darkwing.
+    - Darkwing's poller rule is accepted and amends addendum B section 5.
+      The poller decides whether to write a read by comparing its digest
+      against `task_current`, not against the task's raw latest row.
+      Compared against the raw row, a stale write followed by a person's
+      real move back hides that move from both views. The prototype
+      shows it on `vikunja:3/46`. S3 carries the rule and a test for it.
+    - One condition for the writers. Both views compare `read_at` and
+      `at` as text, and the schema doesn't check their format, which was
+      already true of v3a's external-change view. Every writer, S2's bus
+      and S3's poller, stamps both columns in one fixed-width UTC form
+      with the same precision. S2 and S3 each test that a mixed-format
+      write is refused or can't happen.
+    - Dewey moves `checks/slice1-verify.mjs` from v3a to v3b in Dewey's
+      own working files. Darkwing's fixture replay already shows v3b
+      agreeing with the mockup on all 72 rows.
