// Fix 2 — validate DSCA33/45 Hoffman-mined renders against the live Hoffman originals.
// For each model: render its _srcSerial (an already-uploaded unit) via the new render
// path and content-normalized-compare it to GET /api/v1/TestReportDataFiles/{_srcSerial}.
// --apply marks passing models `validated:true` in dsca33-45-templates.json (the render
// gate). Read-only otherwise (no DB writes, no Hoffman writes).
process.env.DSCA_VALIDATE_MODE = '1'; // open the render gate for the compare
