Flare & PSV datasheets (API 520/521/526)

Two purpose-built relief datasheets: a single-form PSV datasheet (orifice selection, valve type, inlet/outlet drop, reaction force → one API 520/521/526 verdict) and an FM-EN-17 flare-header datasheet that mirrors the pump datasheet's header-conditions-plus-per-source-rows layout, gated so it can't be issued while a scope note is blocking.

• You need one RFQ-ready form for a relief valve covering sizing, valve type, and inlet/outlet drop instead of stitching together three separate calculator outputs.
• You're rating a flare header across multiple relief-contingency scenarios and need a datasheet that shows the governing case per source.
• You want to confirm a flare/PSV datasheet can't be handed out while the underlying solve has an unresolved honesty block.

The flare datasheet button is hasBlocking-gated — it disables itself whenever a built-up-backpressure-exceeds-MABP or partial-non-convergence blocking scope note is active on the current solve, so a failing rating can't quietly become a clean-looking RFQ document.
