Making outline
- Cold form a selected resistance-alloy strip, attach Kelvin sensing/current pads and protect the mechanical assembly
- 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.
Canonical reuse assessment
"Wirewound/film stock may supply material but their RF/general resistor identities are not automatically qualified current shunts."
