Field notes
Written from production work rather than from reading. Each of these is a problem that took real days to solve the first time and takes an afternoon once you know the shape of it.
You are in scope wherever you sit, and enforcement is live. Processor posture, in-Kingdom hosting on the client's account, and no-persistence design: the decisions that shrink the compliance surface by construction.
Font loading races, bidirectional text, numeral conventions, RTL mirroring, page breaks, serverless cold starts, and why the document should never touch disk. With a checklist.
Hash chains that must survive rejections, invoice counters that must survive a redeploy, CSR field conventions, TLV QR encoding with Arabic seller names, and the PDF-versus-XML trap. With a design checklist.
Send the specifics. A short, direct answer costs nothing and is usually faster than another week of searching.
