Making outline
- Populate discrete transistor voltage/current comparators, analog delay/hysteresis and reference network
- 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
"New incorporated module distinct from charger controller and bench protection references; generic semiconductor/passive stocks are constituent candidates."
