This directory preserves the ADS8588S legacy PCB, native project and custom
rules from b0172a2f65902c7281cf4a8454f192dc791a9ef9. They were copied from the
verified starting snapshot under artifacts/dual-servo/baseline/ads8588s/;
their normalized text was compared with that Git commit before copying.
provenance.json records the exact copied-file SHA-256 values.
board.net is the original fresh KiCad netlist from
artifacts/plan-audit/ads8588s/20261018T144449Z-6eoy6y27/. The original
pcb_ci_baseline.json was copied without changing its hashes, known blockers,
parity details or constraints. Its text hashes normalize line endings; the
provenance hashes preserve the copied bytes.
These are immutable historical regression inputs, not the current PCB and not fabrication evidence. The archived design remains blocked. Historical tests must compare these files to the unchanged expected blockers. Active PCB, prototype and release checks operate on the current design and must reject the same faults rather than accept them as historical exceptions.

Questions
How big is the Before PCB?
It measures 130 × 95 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Before use?
162 parts, built around the SN74LVC3G17DCU, INA241A2ID, ADS8588SIPM and FD6288T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Before KiCad files?
From the magic-alt/fpga-servo repository on GitHub, at the commit this page was made from: the board is docs/reviews/layout_entry_repair_2026-10-09/before.kicad_pcb and its schematic hardware/ad7606c_servo/adc_core.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Before design in my own project?
Its repository states no licence, so its author keeps all rights: ask magic-alt before reusing the design.
