Server-044 KillWorkerAsync catch path now calls _metrics.SessionRemoved
so the open-session gauge does not leak when KillWorker throws.
Server-045 KillWorkerAsync routes through a new
GatewaySession.KillWorkerWithCloseGateAsync that takes the
per-session close lock, so concurrent kills count SessionsClosed
exactly once.
Server-046 CloseSessionCoreAsync's SessionCloseStartedException branch and
ShutdownAsync's kill fallback both increment SessionsClosed (not
just the gauge), so the counter and gauge stay consistent.
Server-047 ApiKeysPage.ConfirmPendingAsync holds PendingAction across the
awaited action and clears it in finally, matching the sessions
pages.
Server-048 Closed: the 044/045 regression tests cover the previously-
untested kill paths.
Server-049 IDashboardSessionAdminService + DashboardSessionAdminService
now carry XML docs that pin the Admin gate, missing-session
return-Fail semantics, and the dashboard-admin-kill reason.
Server-050 CloseSessionAsync and KillWorkerAsync catch unexpected
exceptions after the SessionManagerException catches and return
a friendly Fail; OperationCanceledException tied to the caller
token still propagates.
All resolved at 2026-05-24; 503/503 gateway tests pass.
