Making outline

Form one ceramic cavity carrier with defined conductive feedthrough topology.
Metallize pads, through connections and perimeter; inspect seal geometry and insulation.
Characterize electrical/RF witness carrier.

What remains unresolved

Co-fired versus post-fired via sequence/feedthrough sealing recipe remains unchosen.
Full inventory, quantities, losses, capability compatibility and acceptance remain unreviewed.
