rhythm: 2026-07-18 daily brief + DEC-2026-003 cutover go package

Queue hygiene: DecisionQueue gained the missing prepared package for the
now-unblocked BINKY-WP-0004-T06 cutover; OfficeHourQueue and
AutopilotWorkQueue healthy (hub fix-consistency skipped — green lane,
no network).

+# Daily Brief — 2026-07-18
+
+## Decide now
+- **DEC-2026-003 — Go for executor cutover** (DecisionQueue.md): all three
+  gates cleared today; approving lets agents run the cutover runbook and
+  retire the workstation cron bridge. ~5 min.
+
+## Progress
+- **Workstation-independent executor is deployable**: agent-harness deployed
+  on Railiance (HARNESS-WP-0001-T06), binky-control onboarded as tenant #1
+  with instance manifest and three clean definition proof runs (T07,
+  `.kaizen/schedule.yml` + `integrations/harness-tasks/`). BINKY-WP-0004-T06
+  cutover is unblocked — only the founder go remains (see Decide now).
+
+## Risks
+- No register changes. (Cutover, once approved, removes the single-workstation
+  dependency of the daily rhythm.)
+
+## Best next hour
+Approve DEC-2026-003 — one 5-minute go decision unlocks retiring the cron
+bridge and completes BINKY-WP-0004. Carry-over: the two suspicious mails
+flagged in `mailmeta/mail-log.md` still await a human glance.
