Operators cannot place, move, or remove anchors. However, if a step-level anchor was placed during Author Mode, it is visible in Operator Mode exactly as authored. The anchor provides spatial guidance during procedure execution. *** ## Visibility Rules The Step Anchor appears in Operator Mode only if: * The author placed a gem anchor for that specific step. If no anchor was configured for a step: * No gem or tethered line appears. Anchor visibility is evaluated per step. *** ## What the Operator Sees When a gem was placed during authoring: * The anchor is visible in the physical environment. * A tethered line connects the Step Main Panel to the anchor. * The line updates dynamically as the user moves. This visual connection helps the operator understand: * Where the step applies * Which physical location is relevant * Where attention or action is required *** ## Interaction Behavior In Operator Mode: * The gem icon cannot be selected. * The anchor cannot be repositioned. * The tether cannot be modified. * The anchor remains fixed relative to the QR anchor. All anchor behavior is locked to the author-defined configuration. *** ## Step-Level Behavior Gem placement is step-specific. When navigating between steps: * If the new step has an anchor, the tether appears. * If the new step does not have an anchor, no tether is shown. * The system does not carry anchors across steps. Each step maintains its own independent anchor configuration. *** ## Relationship to QR Anchor The gem placement is spatially relative to the confirmed QR anchor. If the operator performs a **Rescan**: * The QR anchor updates. * The step anchor repositions accordingly. * The relative placement defined by the author is preserved. This ensures consistent spatial alignment even after re-anchoring.
