# Restored v0.4.46 — 2026-10-19

This directory is the active restart point. No incomplete current-sensing
implementation was merged into it. All 133 published source files are unchanged
from the saved v0.4.46 publish bundle.

Fresh build and TypeScript pass; all 5,323 PCB/CAD records match the saved
baseline exactly. Native checks report zero errors and the existing 175
warnings. All-layer Gerber shorts checks pass. Logs are in
`reports/restored-build.log` and `reports/restored-shorts.log`.

This does not erase inherited independent drill-clearance findings or replace
stock, mechanical, firmware-in-hardware and fabrication qualification. No push
was performed.

Two MCU ADC-capable pins (STM32G030 physical pins 12 and 15) are unused in this
baseline. Inline signed-current telemetry on both windings is technically
feasible with two series shunts, two PWM-tolerant bidirectional amplifiers,
local bypassing and ADC filtering. Integration still needs targeted placement,
Kelvin routing, appropriate current widths, sampling/calibration and complete
regression validation. Driver current-regulation shunts alone are not a
continuous signed winding-current telemetry system.
