The package passed ZIP CRC and all 24 internal SHA-256 checks. It
is external to PFES and must be supplied with this handoff.

## Source of truth

```

The PDF is for engineering review. The CSV pin maps are an independent review
path. Manufacturer datasheets and the physical module supersede preliminary
footprints.

## Current accepted state

- electrical schematic complete for PCB-layout handoff;
- no released fabrication package;
- no canonical Git repository;
- PIO-only initial scope;
- first article restricted to standard read-only ATA/ATAPI operation;
- flash erase/program work blocked.

## Required next work

1. Open the project in KiCad 9 and run ERC.
2. Resolve every ERC item deliberately; do not suppress unknown failures.
3. Measure the physical FK723M1-ZGT6 socket-bank spacing.
4. verify PATA, LP4, relay, and SWD mechanical footprints.
5. complete PCB layout and DRC.
6. document power, unpowered-drive, reset, and transceiver-OE checks.
7. prepare a first-article read-only bring-up plan.
8. return updated source and reports as a new provenance-distinct package.

## Do not

- create or declare a canonical repository yet;
- describe Rev B0 as fabrication-ready;
- power the optical drive from USB;
- substitute TXS/TXB automatic translators;
- enable DMA/UDMA;
- enable erase/program payloads;
- treat `RECOVERY_ARM` as absolute hardware write protection.

## Repository trigger

Request repository-readiness review only after the source boundary, layout,
validation baseline, and maintenance model satisfy PFES-ENG-045.
