Methodology is versioned, calibration is published, the contract is signed. The Library is the room that holds these objects, with the dates on which each was last refreshed and the dates on which the next refresh is due.
A 64-page reference on the operational state of AI-enabled cross-border trade intelligence as of Q1 2026 — adoption, the OFSI Q1 changes, the entity-resolution stack across 32 consigning territories, and the next twelve months of methodology work. Cited evidence; primary-source citations in the back matter.
Apr MMXXVI · 64 pp · Analyst desk · CC BY 4.0An 18-page operational brief for commodity, shipping and trade-finance teams on the January OFSI bulletin. The threshold change, the new control-leg tests, the 412 added entities and the measured screening-miss differential. Checklist included.
Feb MMXXVI · 18 pp · Analyst desk · CC BY 4.0The current production methodology for the Signal Routes score. Eight inputs, ensemble design, constraint table, calibration window per lane class, suspension procedure, errata. Signed against the v3.2 release tag.
v3.2 · Jan MMXXVI · Engineering desk · signedIntegration starter for in-house data teams. OAuth 2.0 flow, the four endpoints with reference requests and responses, the deprecation policy, the audit-receipt format and the schema-evolution guarantees. OpenAPI 3.1 file linked from the back page.
v3 · Mar MMXXVI · Engineering desk · CC BY 4.0The entity-resolution and schema-harmonisation stack across the 32 consigning territories. Per-territory confusion matrices, the date each territory's calibration was last refreshed, the next refresh windows for the five territories in active onboarding.
v4.1 · Mar MMXXVI · Engineering desk · signedPer-lane-class calibration plots for the Signal Routes score, with the rolling 52-week window and the suspension events documented inline. The two historical suspensions — dates, lane classes, durations, root causes — are present in the appendix.
Q1 MMXXVI · Engineering desk · CC BY 4.0Four reference titles are not on the open shelf. They are not secret; they carry data — counterparty-level evidence, signed audit receipts, deal-specific calibration windows — that is private to particular clients or to particular regulators. They are available on request, against a stated purpose, with the corresponding methodology release named in the request.
The four titles are: the per-client calibration appendix, the regulator audit pack template, the integration runbook for the platform workspace, and the data-handling annex for the investigations workspace. The first reply to a request usually confirms availability the same working day.
Write to methods@unitedtradecrest.com with the title, the methodology release you wish it against, and a brief note on the purpose. The desk replies same working day.
Every reference in the Library carries an errata page. When an error is identified — once, in the life of the product so far, in a public reference; three times, in internal references that had not yet shipped — the correction is dated, signed by the desk that issued the original, and forward-carried into every subsequent reference that touched the same ground. The corrected reference is republished against a new minor version; the corrected page is linked from the original. The original is not deleted. The Library does not pretend an error did not happen.
