The working papers behind everything on this site.
Every figure we publish came out of a document that grades its own sources and records its own corrections. Three are published and linked below. The rest are being prepared for release rather than written for it — which is slower, and the reason the numbers hold up.
Published
What changed on 19 July 2025, how class is derived from measured density, and what a defensible declaration basis has to record to survive a carrier reweigh and a dispute.

Article 24, the 50% empty-space cap, what counts as empty space, and how to measure void ratio per carton now so the 2030 date is a report rather than a project.

The divisor moved 166 to 139 — and, barely reported, fractional dimensions now round up. Together they bill a 2,183 in³ box at 19 lb where it used to be 14, and put break-even density inside a band NMFC already penalises.

In preparation
The document you get back from a measured run: physical delta against your own baseline policy, priced with your rate card, with the method attached so your team can reproduce it.
Statusproduced per engagement · sample on request
The REST surface, the CSV contract, the object model, and the shape of the payload each connected system receives. Written for the engineer who has to wire it, not for the buyer.
Statusin preparation
The measurements to take before anything changes, because without a pre-baseline there is no provable result and the renewal conversation has nothing to stand on.
Statusin preparation
How we grade a figure A, B or Measured, why a C-grade number never carries a headline, and the corrections we have made against ourselves and kept on the record.
