- Endpoint rewrite: the driver now connects to the configured host AND port (scheme match, advertised path kept) instead of the server-advertised URL — fixes NAT/port-map upstreams and lets an in-test proxy carry the session (SDK SelectEndpoint rule). - TcpStallProxy + OpcUaClientDriverStallWireTests: the in-place blip (#670) is now wire-tested on loopback — one Bad, frozen read stamp, same session, identical value republished Good, a post-recovery change arrives, no source-time regression after the SDK's late backlog flush. - Defect found by that test, fixed: a change published right after a stall rode a Publish response the SDK timed out and never republished, leaving the node Good on the pre-change value indefinitely. New trailing reconcile read (Timeout + KeepAliveInterval after recovery) publishes any Good value newer than the last accepted one, through the replay guard's mark. - IDriverConnectionLossSource (Core.Abstractions): opt-in definitive-loss signal. DriverInstanceActor attaches in PreStart / detaches in PostStop and turns a raise into a disconnect only while Connected. OpcUaClient raises once per session on keep-alive BadSessionIdInvalid/BadSessionClosed/BadSessionNotActivated/ BadServerHalted (measured: the SDK never re-opens a halted channel) or a dropped subscription; ambiguous codes stay with the #527 watchdog. - Replay guard: one Information summary per recovery when the window closes ("dropped N late notifications across M refs"), with a timer so quiet subscriptions log it too. - ReconnectPeriod deleted (options, AdminUI form, docs, tests); stored configs that carry reconnectPeriod still parse in the factory, probe and browser. - Docs: OpcUaClient.md, DriverLifecycle.md, driver-specs.md, CLAUDE.md.
