Summary

Changing the selected distribution kept the host from the one just left.

The selected host lives in the URL (/console/hosts/:host) and the distribution does not. So after a switch the console stayed on the old host's path under the new distribution and showed "No such host". The same happened after Unlink moved to the next distribution.

• Whenever the selected distribution changes, the console goes back to /console, which lands on the new one's first host, or its "No hosts yet" state. That covers the switcher, Unlink moving to the next one, linking another distribution, a distribution a teammate unlinked, and Settings pointing a distribution at another table.
• It does not happen on the first load, so a link to a host still opens that host, nor when the list reloads and the distribution comes back unchanged.
• The navigation replaces the history entry: the host left behind is not one Back can show under the new distribution.
• The console body is keyed on the distribution, so nothing carries over from the previous one: not its host list, and not an open editor where two distributions share a host name. The new distribution is never asked for the old one's host.

Known limit: the distribution is still not in the URL, so Back does not switch distributions. Putting it there is a separate change.

Tests

Lint, typecheck and Playwright (183/183), all green. New e2e/distribution-switch.e2e.ts (12 specs) serves each target its own hosts and rules:

• switching lands on the new distribution's first host, shows its rules, and switching back works
• the new distribution is never asked for the old one's host
• a distribution with no host shows its empty state at /console
• a host name both distributions have shows each one's own rules
• a reload after switching keeps the distribution and its host
• a viewer switching lands on the new host too
• unlinking, linking another, and a teammate's unlink each land on the next distribution's host
• Settings pointing at another table loads that table's hosts
• a link to a host still opens it on load

10 of the 12 fail on dev; the other two (the shared host name and the deep link) guard behaviour that already worked.

Ticket

CF-58

Checklist

• CI is green (lint, typecheck, schemas)
• If the rule shape changed: shared/ schemas and their shared/examples/ were updated together (n/a)
• If the rule shape changed and the console API exists (step 2): its OpenAPI spec $refs the updated schemas — no inline redefinition (n/a)
• The module still takes no input about, and creates no, aws_cloudfront_distribution (except under examples/)
