What its author says it does

Copied from the file, not written here

Stage footprints on a KiCad PCB so Update-PCB-from-Schematic adopts them without duplicates, probe board geometry, run DRC, and render layers for inspection. Use when asked to put footprints on the pcb, prepare a board for layout, or verify a .kicad_pcb change.

PCB footprint staging & board ops

Engine: $(kx root)/kicad_lib/pcb.py (python API: PYTHONPATH=<repo> or cwd=<repo>; CLI: kx is on PATH) (netlist, load_footprint, stage, edge_cuts_bbox, empty_board_from). Worked example: tests/test_pcb.py.

Staging flow (Update-PCB adopts, no duplicates)

pcb.netlist(SCH) → comps[ref]["tstamps"] — that uuid IS the link; nets is the connectivity ground truth (assert designed members!). Root-sheet local-label nets are prefixed "/" (/VOUT); power nets (GND, VCC) are not.
pcb.load_footprint(mod_path, "Lib:Name") — renames for the board, strips file headers (.kicad_mod has no top-level uuid; instances do).
pcb.stage(board, fpdef, ref, value, at, tstamps_uuid, sheetfile) — inserts after the layer clause: uuid, at, path "/<tstamp>", sheetname, sheetfile; sets Reference/Value; refreshes EVERY item uuid. Pads stay netless — the sync fills them.
Stage in a grid CLEAR of the outline: pcb.edge_cuts_bbox(board).
Gates: save → reparse → kicad-cli pcb export svg accepts → render PNG → eyeball → commit.

Notes

pcb.empty_board_from(donor) builds a minimal valid board (header + layer stack + setup + net 0) from any existing .kicad_pcb, read-only.
DRC: kicad-cli pcb drc --output drc.rpt --severity-all BOARD — set-diff vs baseline exactly like ERC (kicad-review skill).
.kicad_pcb round-trips BYTE-IDENTICAL (validated on a 2.3 MB real board): pcb pts dialect (≤5 points inline, then 4-per-line chunks) + token wrap at column 72 — sexp.dumps sniffs the root tag, or pass dialect="pcb" when serializing subtrees. Hand-edits diff zero-noise.
Update-PCB direction is sch→pcb only; never edit refs on the board.
