Driver.OpcUaClient-001 — ReadAsync/WriteAsync/DiscoverAsync captured the session before acquiring _gate, so a reconnect that completed while the operation was blocked on the gate left the wire call bound to a stale, closed session. All three now re-read Session (and parse NodeIds) inside the _gate critical section after WaitAsync returns. Driver.OpcUaClient-002 — OnReconnectComplete ignored the give-up (null session) case, permanently wedging the driver with no Faulted signal and no reconnect loop. The give-up branch now transitions HostState to Faulted, sets a Faulted DriverHealth with an explanatory message, and re-arms a fresh SessionReconnectHandler (TryRearmReconnect) against the last-known session so an always-on gateway self-heals. Driver.OpcUaClient-003 — BrowseRecursiveAsync discarded browse continuation points, silently truncating large remote folders. It now loops on BrowseResult.ContinuationPoint calling BrowseNextAsync and appending each page until the continuation point is empty. Driver.OpcUaClient-004 — driver-specs.md §8 namespace handling was absent. Added NamespaceMap (built from session.NamespaceUris at connect, rebuilt on reconnect) which persists discovered NodeIds in the server-stable nsu=<uri>;... form; reads/writes re-resolve that form against the current session so a remote namespace-table reorder no longer misaddresses nodes. Added the TargetNamespaceKind option + UnsMappingTable and ValidateNamespaceKind startup enforcement. Driver.OpcUaClient-005 — OnKeepAlive read/wrote _reconnectHandler without a lock, racing the SDK keep-alive timer thread and leaking handlers. The check-and-set in OnKeepAlive, the take-and-clear in ShutdownAsync, and the dispose/re-arm in OnReconnectComplete now all run inside the _probeLock critical section. Adds OpcUaClientNamespaceTests (11 xUnit + Shouldly regression tests) covering ValidateNamespaceKind and the NamespaceMap stable encoding. Reconnect/browse wire paths remain fixture-gated per finding -015. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
