Pumps live driver OnDataChange notifications into CachedTagUpstreamSource so ctx.GetTag in user scripts sees the freshest driver value. The last missing piece between #243 (composition kernel) and #246 (Program.cs wire-in). ## DriverSubscriptionBridge IAsyncDisposable. Per DriverFeed: groups all paths for one ISubscribable into a single SubscribeAsync call (consolidating polled drivers' work + giving native-subscription drivers one watch list), keeps a per-feed reverse map from driver-opaque fullRef back to script-side UNS path, hooks OnDataChange to translate + push into the cache. DisposeAsync awaits UnsubscribeAsync per active subscription + unhooks every handler so events post-dispose are silent. Empty PathToFullRef map → feed skipped (no SubscribeAsync call). Subscribe failure on any feed unhooks that feed's handler + propagates so misconfiguration aborts bridge start cleanly. Double-Start throws InvalidOperationException; double-Dispose is idempotent. OTOPCUA0001 suppressed at the two ISubscribable call sites with comments explaining the carve-out: bridge is the lifecycle-coordinator for Phase 7 subscriptions (one Subscribe at engine compose, one Unsubscribe at shutdown), not the per-call hot-path. Driver Read dispatch still goes through CapabilityInvoker via DriverNodeManager. ## Tests — 9 new = 29 Phase 7 tests total DriverSubscriptionBridgeTests covers: SubscribeAsync called with distinct fullRefs, OnDataChange pushes to cache keyed by UNS path, unmapped fullRef ignored, empty PathToFullRef skips Subscribe, DisposeAsync unsubscribes + unhooks (post-dispose events don't push), StartAsync called twice throws, DisposeAsync idempotent, Subscribe failure unhooks handler + propagates, ctor null guards. ## Phase 7 production wiring chain status - #243 ✅ composition kernel - #245 ✅ scripted-alarm IReadable adapter - #244 ✅ this — driver bridge - #246 pending — Program.cs Compose call + SqliteStoreAndForwardSink lifecycle - #240 pending — live E2E smoke (unblocks once #246 lands)
