Making outline

Build gas-ionization survey chamber with guarded electrometer and separately realized charge/photon references
Detailed procedure and acceptance remain unresearched.

What remains unresolved

Manufacture, quantities, suitability and complete inventory remain unreviewed.
Current memory-first method needs source and compatibility review.
