+    10-12". Decision 48 item 1 is amended for one case only: a read-only
+    Console preview at its own hostname, behind Pocket ID forward auth
+    limited to Jason's group, with the old build at mosaic.woltje.com left
+    up. In-app sign-in and general access beyond localhost stay out of v1.
+    - The route opens once rev-sol-01 passes ops-01's route proposal,
+      without asking Jason again.
+    - Target: Jason signs in on 2026-10-12, at the latest by
+      2026-10-13T05:00Z. This replaces decision 92's preview dates.
+    - Row 74 is unblocked and Dewey starts it now; their row 59 review is
+      done. Darkwing and Filbert review it ahead of their own rows. Both
+      reviewers and Sage's gate rerun stay. No gate is dropped for the
+      date.
+    - Cut for the date: the service script, its unit template and test,
+      and its TOOLS.md entry go to a follow-up row (this also takes row
+      74 off `docs/TOOLS.md`, which row 70 edits). After the row lands
+      Sage starts the preview as a transient user unit with
+      `systemd-run --user` on its own loopback port, 7332. Port 7330
+      holds the operator's foreground Console from 2026-09-26, which
+      stays.
+    - The tradeoff: a transient unit doesn't survive a reboot and isn't
+      reviewed as a file. It runs one reviewed command line, which the
+      install record states, until the follow-up row ships the unit.
