Abstract
This work presents the current mechanical prototype of a SAR membrane antenna being tested at the Canadian Space Agency. The current concept of the C-Band membrane antenna calls for a 4 m by 10 m membrane, a wing of that antenna measuring 4 m by 5 m. The prototype measures 2 m by 3 m, which is slightly longer than a half-scale prototype of one wing. This prototype will be fully representative of the mechanical concept of the CBand membrane antenna. The three horizontal layers, with the vertical layers embedded, are flattened one on top of the other for stowage. When deployed, the bottom layer and the top layer are separated by approximately 15 cm. A mechanism has been devised to tension the membranes and deploy them. Each side of the spacecraft has a frame made of struts and the deployment is activated from a single six-bar linkage mechanism. The hinges are made of spring tapes, guiding devices, and a shape memory alloy. The current state of the integration of the frame is reported here, as well as the tests done to assess the performance of the tensioning scheme of the membrane.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
