A docs-only PR writes the BOM from the board's as-built values and flags every reference where the schematic differs. Regenerated Gerbers and drill match the committed outputs exactly, 42 of 42 flashes and 89 of 89 hits. But five component values differ between board and schematic, both labelled rev A. C11 is 1 uF on the board and 100 uF in the schematic, which moves the headphone corner from about 50 Hz to about 5 kHz at 32 ohms. R6 is 3.3k against 330 ohms in the keying notch. The README now tells builders to read the rev A notes before ordering parts.
