Tapping a discovered desktop in the phone's companion remote did nothing:
the device list emptied to "No devices found on your network" and no
connection was ever made. Manual IP:port entry silently did nothing too.
A host advertises every local IPv4 address, so a PC with virtual adapters
(WSL, Hyper-V) broadcasts addresses the phone cannot route to. The client
races them all, and cleanup of the losing candidates awaited
`sink.close()` on channels that never connected. That future never
completes in web_socket_channel: the close future waits on the local
stream's listener, which is only attached on the connect-success path. So
the race never finished, the winner was never joined, and the flow just
stopped with no error.
Cleanup now tracks whether a candidate ever connected: unconnected probes
get a deferred close armed on `ready` settling instead of a blocking
await, and they skip the terminal drain since they hold no host admission
slot. The managed join gets a real connect timeout that surfaces as a
typed timeout error, and disconnect during a pending connect closes the
socket once the connect settles rather than blocking on it.
Two paper cuts around the same flow: a failed attempt now restarts
discovery instead of stranding the cleared list on "No devices found",
and the desktop's server card shows its listen addresses so manual entry
is not guesswork.
close#2077
Introduces shared seams for paginated views, D-pad reorder, media control
routing, async singletons and the device method channel, then points the
open-coded copies at them.
Also removes unused models and duplicated provider/server plumbing, folds
the twice-implemented artifact store in the server, and factors the
repeated Flutter toolchain prologue in CI into a composite action.
Keep a running companion-remote host's crypto identity in sync with the
active profile: subscribe to PlexHome/connection/join streams and rebuild
auth contexts (restarting the broadcast when they change) so a removed
home user or revoked borrowed connection stops controlling the host.
Serialize host start/stop/crypto-rebuild through a lifecycle lock, clean
up peer subscriptions before re-listening, and guard the replaced-client
onDone against clobbering the new client's session. Drop the context.mounted
guards that aborted an app-level host start, fix the DiscoveryView
init-flash/stuck-on-throw, and delete the dead initialize*Crypto helpers.
Replace session ID + PIN auth with HKDF-derived home secret and
per-session AES-256-GCM encrypted channel. Auto-start remote server
on host devices, auto-discover hosts via authenticated UDP broadcast.
