Detailed Description
After phase C3 the activity hosts a shared ID header (line edit + Random button + "Preview as Shadow" toggle) above a QTabWidget with five tabs: Sentient, Agent, Remote, Hub, Iris. Each tab is an IdentityAssetLabTab driven by the corresponding generator's AssetParameters schema (§IS-A-2.3). Editing the ID at the top cascades through every tab; clicking a thumbnail anywhere writes its ID back into the shared field. The Sentient tab adds a "Hold to blink" button that eases the eye-closure animation.
