HISTORICAL SYNTHETIC PDF PROVENANCE

These three JSON files were copied unchanged from the retained R3 execution
ledger and its original repeat-shop fixtures. They are reference material for
the included PDFs, separate from the cabinet/inch/offcut CSV exercises.

The PDF helper added an oversized synthetic demand, pdf-unplaced, to the base
repeat-shop fixture. Its hand-derived witness places two 400 by 500 mm blanks
in one 1000 by 500 mm source with two 3 mm kerfs and a 194 by 500 mm remainder.
The full job remains partial because the added 2000 mm-wide demand is unplaced.
See ../../sample-output-manifest.json for the helper identity and exact changes.

The helper performed a software commit in a synthetic in-memory inventory.
The resulting stock ID differs from the proposed plan-node ID. No physical
piece was observed or cut; a fixture label such as "Measured Birch piece" is
part of the synthetic example, not an observation of a user's stock.

The original ledger records macOS headless PDFKit text/page/media-box checks.
It records no rendered-page/clipping review, native UI, printer, share sheet,
device or formal tagged-PDF accessibility check. This task copied and matched
bytes only. These samples do not establish current-R4 behavior or release status.
