state: apply requested tags on a key login that owns them
...
A requested tag the key's user owns directly, or the key's tags own one
hop away, replaces the key's tags instead of refusing the login.

The new tags may approve announced routes. Approval runs once the policy
manager knows the new owner, as after a registration.

Registration runs the approval itself, once the policy manager knows the
node's owner, for a new node key or a change to the announced routes.

auth: store a client's earlier expiry and expire a tagged node at logout
...
A client may bring its expiry forward, which turns expiry on for a node
without one, but still cannot push it back. Logout expires tagged nodes
too.

...
The client then rotates its node key and logs in again, so no key is
judged under the expired one. The machine stays authorised.

state: give another user's key on a tagged machine a new device
...
Only a key that speaks for a tagged node re-authenticates it: a tagged
key, or one of the user it was tagged from, which takes it back with a
new node key. Another user's key or login adds that user's own device.

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.

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

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.

api, policy/v2: refuse route prefixes with host bits
...
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.

state: never serve a single address inside the node ranges
...
Such a route names a node, not a subnet: it stays approved and listed
but no viewer gets it. Via inclusions skip the election, so the rule
sits on everything RoutesForPeer returns.
