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.

hscontrol: refuse a key expiry that cannot be encoded
...
handleRegister, the OIDC auth path and SetNodeExpiry refuse it. Expiries
are stored in UTC, which SQLite can read back, and loaded in UTC, as
PostgreSQL returns the server's zone. The v1 API answers 400.

mapper: skip peers whose key expiry cannot be encoded
...
json.Marshal refuses a year outside [0,9999], so one stored expiry
failed every map with that node. TailNode and key patches send UTC, the
builder drops what fails and the boot scan names the node.

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.

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.

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.

Registration approval runs on the node the writer replaces. A policy

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.

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.
