Making outline
- Design one discrete current-control candidate with command and protection functions.
- Populate and connect circuit to earlier test supply and independent electrical load.
- Measure response and record unverified module-size/noise/control limits.
What remains unresolved
- Discrete route has unproven flagship size/noise/bandwidth; do not imply an IC is supplied.
- Full inventory, quantities, losses, capability compatibility and acceptance remain unreviewed.
