DeleteNode's early persistMu unlock is safe only while node persists
stay UPDATE-only; say so where the lock is declared.

mapper: show an expired peer online, without endpoints or DERP
...
A connected expired node shows online to its peers. Neither its map
entry nor endpoint, DERP or disco patches carry the paths to reach it.

mapper: trim the Hostinfo sent to peers and to the node itself
...
As on Tailscale SaaS, the node's own entry keeps Hostname, RequestTags,
RoutableIPs and Services; peers get Hostname, OS, Services without
peerapi-dns-proxy, SSH host keys and AppConnector, and resend on those.

mapper: keep an expired node authorised in its own entry
...
Tailscale SaaS sends an expired node MachineAuthorized and no Expired
flag; its past KeyExpiry already moves the client to NeedsLogin.

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.

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.

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.

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.
