Evidence ledger
This page is for due diligence. Every factual statement on this site is registered here once, with two independent marks. Evidence level says whether it has been checked; disclosure policy says whether it may be published. They are not interchangeable: a verified fact may still be barred from publication.

ai.candidateModel output is a candidate signal. Anything without a source, or that cannot be cross-checked, does not become a stated fact.[public]ai.humanWhether the problem was framed correctly, whether the sources hold, what is fact versus inference, and whether a recommendation fits you, all remain human responsibilities.[public]ark.closedARK is not an open service and not a free diagnostic. Its operating range and responsibility boundary have not been signed off, so there is no public registration.[public]ark.notgrowthFinished software is not client growth.[public]ark.stopWhen evidence is insufficient, a dependency is missing or a hard gate fails, the process stops rather than forcing an answer.[public]ark.whatARK produces candidate markets, entry-path waves, hard-gate results and the reasoning behind them. Every conclusion traces back to the inputs and rules that produced it.[public]case.redefineThe client arrived with a website, search and enquiry problem. The project redefined it as a buyer trust chain and market-entry asset problem.[public]case.yqautoYQAuto is the one engagement cleared for full public description, in commercial-vehicle telematics video and active safety.[public]client.notNot a fit for buyers looking for cheap web work, or for anyone who wants a growth guarantee without providing the facts.[public]client.priorityThe work is for Chinese companies that already have a product, a team or an operating base, and are entering overseas markets or hitting problems there.[public]engage.freeA free diagnosis is a limited-scope entry point, never free delivery of a complete plan.[public]engage.longtermLong-term accompaniment is built on trust from prior project work. It is not the default entry point, and I reserve the right to choose clients.[public]engage.outsideLegal, tax, audit, certification and investment opinions require the relevant qualified party and are outside what I take responsibility for.[public]engage.threeThree depths of engagement: diagnosis and advice, a scoped project, selective long-term accompaniment. Different relationships, not packages sorted by duration.[public]identity.baseThe base is operations and consulting. AI systems are an evidence layer that strengthens judgement, not the story this practice tells about itself.[public]identity.brandXXF Global is a personal advisory practice and its official site. It is not a legal entity and has no staff.[public]identity.nameXia Xianfeng advises Chinese companies on overseas growth.[public]method.chainThe overseas buyer trust chain has three gates: understand, verify, buy. They are sequential; a break in one makes everything after it irrelevant.[public]method.transferThe gates came out of one real engagement. For another industry the decision roles, risks and required evidence must be identified again. Borrow the structure, not the checklist.[public]private.fieldsPhone, private email, address, identity documents, tax and payment details are barred by the disclosure boundary, verified or not.[withheld]derived 1
method.trafficMore traffic does not repair a verification failure. Doubling it just doubles the number of buyers who leave.[public]unverified 9
case.noresultNo verifiable measurement exists for traffic, enquiry, order or revenue improvement, so no such claim is made.[withheld]count.clientsNumber of companies served[review]cv.certsAdvisory, teaching and certification credentials[review]cv.currentCurrent employment and how it may be described[review]cv.datesStart and end dates for each period[review]cv.educationInstitutions, degree level and completion status[review]cv.employersPast employers and employment relationships[review]cv.resultsRevenue, margin and sales performance figures[review]cv.titlesJob titles held[review]undecided 3
engage.termsFees, timelines and deliverable lists are not settled, so they are not published.[public]private.contactNo contact channel has been decided. No verified public address exists, so none is published.[withheld]site.directionWhether a standardised product line sits alongside the consulting work is undecided. The structure leaves room for either.[public]
