First block of the notification bridge for WearOS support (microg#2843). Implements parsing of ANCS 'Get Notification Attributes' Data Source frames into a structured value object (uid, app identifier, title, subtitle, message, message size, date, action labels) with strict bounds checking, plus a Control Point request builder. Pure JVM, covered by 7 unit tests.

What
The first, fully self-contained block toward the notification bridge for WearOS support (#2843): a pure-JVM ANCS (Apple Notification Center Service) notification-attributes parser and model.
AncsNotifications.parse(byte[])decodes a Notification Attributes Data Source frame into a structured value object (notificationUid,appIdentifier,title,subtitle,message,messageSize,date, positive/negative action labels).AncsNotifications.readAttributesRequest(uid, ids…)builds the matching Control Point request.com.google.android.gms.wearable.AncsNotification, ready to be routed viaWearableListenerService#onNotificationReceived.Why
The
AncsNotificationAPI surface is currently an empty interface andinjectAncsNotificationForTestingis unimplemented — there is no notification path at all on the wear side. This is the parsing/transport-adjacent core that the companion notification flow needs regardless of which Bluetooth transport lands first.Verification
AncsNotificationsTest) covering full frames, theMESSAGE_SIZEuint32 special case, unknown-attribute skipping, and malformed/truncated rejection — all passing (verified standalone withjunit:junit:4.13.2).Next steps (tracked, device-dependent)
