auth, state: answer an expired node's same-key login with NodeKeyExpired
...
The client then rotates its node key and logs in again, so no key is
judged under the expired one. The machine stays authorised.

...
A login that keeps its node key leaves a live node's expiry alone, even
with a valid key, and a wake-up is not refused for the tags it requests.

state: auto-approve routes in the NodeStore writer, not on reload
...
Registration approval runs on the node the writer replaces. A policy
reload approves nothing, and a map request only when its announced
routes change, so neither re-grants a route an admin revoked.

policy: offer exit routes only to viewers whose rules reach the internet

Every destination overlaps /0, so any rule offered a peer's exit routes.
They now need a rule to the internet, the test exit-node visibility
uses; via steering defers them to a regular grant only on that test.

policy: reduce merged destination prefixes to the node's own addresses
...
Adjacent node addresses merge into one prefix, and each node's filter
kept all of it. A prefix made only of node addresses now shrinks to the
node's own; a prefix the policy wrote, or one the node routes, stays.

Routes are matched as written, so such a prefix never equals the one a
client announces. The approval APIs answer 400 and autoApprovers refuses
it at load and write, with Tailscale's text.
