The rectangular accessory is presented while the source expects C-A. A developed lesson must block attempted seating, preserve the geometry and ask the learner to explain the mismatch.
Recovery and feedback
Hold. Explain. Confirm.
Keep C-B clear of P1, record the evidence gap and name the educator who owns the next review. The receiver repeats the restriction; the sender confirms. Feedback identifies the missed cue. No score or clinical release is invented here.
Public external EON product information. This is not a Healthcare lesson launch. A future accepted lesson will carry its own version, access requirements and learner URL.
