Making outline

Retain independent mineral heat-transfer wall over earlier pit fuel bed, separate specimen/salt shelf and combustion return with cold standoff carrier, add mineral cooling perches and mechanical draft baffle; commission unloaded with independent phase/radiance observations
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.
