Editorial Policy

Proof standards

Market Proof Lab uses a tiered evidence classification system. The distinction between proof and assertion is not a matter of confidence or volume — it is a structural question about the independence, verifiability, and methodology of the underlying evidence. Seven classes are defined below. Classes 1 through 5 constitute proof. Classes 6 and 7 constitute assertion and are never treated as sufficient validation basis on their own.

Class 1: Primary source documentation. Contracts, audited financial statements, regulatory filings, patent registrations, court records, government databases, and other primary documents created by or for a party with direct operational knowledge. Class 1 evidence is the strongest available because it is generated in contexts where the author has legal or fiduciary accountability for accuracy. Market Proof Lab treats Class 1 evidence as the gold standard for factual claims about what a subject has done, agreed to, or legally represents.

Class 2: Independently verified third-party audits and certifications. Compliance certifications (SOC 2, ISO 27001, and equivalents), financial audits conducted by accredited firms, third-party penetration test reports, and independent technical assessments by named organizations with verifiable credentials. Class 2 evidence is strong when the certifying body is independent, the scope of the certification is clearly defined, and the certification is current. Market Proof Lab checks that certificates are not expired and that the scope covers the claims being made.

Class 3: Peer-reviewed or institutional research with traceable methodology. Academic studies, government-commissioned research, and institutional white papers in which the research methodology is fully documented, the data sources are named, and the findings are reproducible in principle. Class 3 evidence is subject to editorial scrutiny of the methodology — a peer-reviewed study with a flawed design is not automatically accepted as proof. We examine sample size, conflict disclosures, and replication status before treating Class 3 sources as probative.

Class 4: Named expert commentary with verifiable credentials and no undisclosed conflict. Written or on-record statements from professionals whose credentials, institutional affiliations, and relevant experience can be independently confirmed. Class 4 evidence requires that the expert's conflicts of interest are known and disclosed. Anonymous expert commentary does not qualify. Commentary that is paid for by a party with a financial stake in the validation conclusion is treated as assertion, not proof, regardless of the expert's credentials.

Class 5: Consistent corroborating signals from independent sources using different methodologies. When multiple independent organizations using different research approaches reach consistent findings on a factual question, the convergence itself constitutes a form of proof. Class 5 evidence is applicable only when the sources are genuinely independent — multiple reports from the same vendor ecosystem, commissioned by the same intermediary, or using shared data are not treated as independent. Market Proof Lab assesses independence by examining funding, data sourcing, and methodology before designating sources as corroborating.

Class 6: Vendor self-attestation alone. Claims made by a subject about its own performance, capabilities, customer outcomes, or market position, without independent verification. Vendor self-attestation is a starting point for investigation, not a conclusion. It is always labeled as such when referenced. Market Proof Lab may use Class 6 claims to identify questions worth investigating, but never to confirm a positive validation conclusion.

Class 7: Unverifiable market statistics. Market size figures, growth projections, and adoption claims that cannot be traced to a named methodology, a documented data source, or an accountable publisher. Market statistics circulate widely in promotional contexts; many originate from press releases, are repeated without attribution, and have no traceable methodology behind them. Class 7 items are noted as unverified when they appear in source material and are never treated as proof of market conditions.

Validation integrity

Market Proof Lab validates claims independently. Our validation conclusions are the product of applying our proof standards to the available evidence at the time of research. Validation integrity means that those conclusions are not adjustable based on commercial pressure, subject preference, or the volume of Class 6 and Class 7 material a subject is able to produce.

Corrections that change proof conclusions. When a submitted correction asserts that a published validation conclusion is wrong, we require Class 1, Class 2, or Class 3 evidence to support the revision. A correction supported only by vendor self-attestation (Class 6) or unverifiable statistics (Class 7) will not result in a change to a validation conclusion, even if the subject strongly disputes the published finding. The rationale is structural: if Class 6 and Class 7 evidence is insufficient to establish a positive validation conclusion in original research, it is insufficient to overturn one in a correction.

This standard protects readers. A publication that changes validation conclusions based on pressure or promotional submissions is not an independent validation resource — it is a managed reputation service. Market Proof Lab declines to operate in that way.

What does change a validation conclusion. Primary documentation that was not available at the time of original research and that directly bears on the conclusion in question. A current, valid certification that we had incorrectly described as expired. A regulatory filing that contradicts a factual claim we published. Named expert correction with documented credentials and disclosed conflicts. These are the categories of evidence that move validation conclusions.

Validation neutrality. Market Proof Lab has no commercial relationship with any subject covered in its proof reports. Validation neutrality is the default operating condition. Any commercial relationship that could affect a validation outcome would be disclosed prominently at the top of every affected page. The current commercial relationship status is: no active commercial relationships with any covered organization. This status is updated on this page whenever the situation changes.

Independence from subject preference. Subjects covered by Market Proof Lab do not control, review, or approve our validation conclusions prior to publication. Subjects may submit factual corrections through our corrections channel and may provide documentation for consideration. They do not receive advance copies for editorial approval. If a subject provides documentation that changes a factual element of a draft, that change is made on evidentiary grounds, not as an accommodation.

Editorial standards

Every proof report and validation output published by Market Proof Lab must satisfy four foundational requirements before it is cleared for publication.

Criteria-first sequencing. Research must define the validation criteria before any named subjects are evaluated. We do not begin with a predetermined conclusion and work backward to justify it. Criteria are drawn from regulatory frameworks, technical documentation, professional standards bodies, and expert commentary available at the time of research. When criteria are contested or domain-specific, we document the source of those criteria and note where reasonable practitioners disagree.

Evidence class labeling. Every substantive claim in a published output is traceable to at least one of the five proof classes defined above, or is explicitly labeled as unverified. Claims that cannot be anchored to Class 1-5 evidence are either removed before publication or clearly identified as assertion. Readers should always be able to identify what kind of evidence underlies any conclusion we publish.

Labeled interpretation. When our editorial team draws a conclusion that goes beyond what a source explicitly states, that interpretation is labeled as such. Phrases such as "Market Proof Lab interprets this to mean" or "in our assessment" signal that the reader is encountering editorial judgment, not a factual assertion from a primary source. We do not present inferences as established facts.

Documented limitations. Each proof report must acknowledge the limits of its evidence base. If documentation is unavailable, if coverage is geographically constrained, if a certification's scope does not extend to the claim being evaluated, or if the evidence base is time-limited, those limitations are noted. We do not publish with false confidence.

Voice and tone

Market Proof Lab writes in an analytical, lab-like register. Our audience is decision-makers, procurement teams, and researchers who need precise, calibrated assessments — not enthusiasm or promotional framing.

Validation-oriented, not promotional. We describe what the evidence shows and what it does not show. We do not advocate for categories, platforms, or providers. Terms like "leading," "best-in-class," or "industry standard" are used only when they are supported by named, verifiable, current sources and attributed explicitly to those sources.

Precision over approximation. Measurements, dates, and counts are expressed as numerals and anchored in time. We use constructions such as "based on documentation reviewed in May 2026" to make clear that findings reflect a specific research window, not a permanent state of affairs. Vague constructions like "many experts believe" or "widely recognized" are replaced with specific attributions.

Active voice and direct structure. Claims are stated directly. Passive voice is used only where the actor is genuinely unknown or irrelevant. Hedging language is applied only when uncertainty is real and is calibrated to the actual evidence base.

Second person is used for reader-directed navigation and instructions. Third person is used for subject descriptions and validation conclusions.

Corrections policy

Market Proof Lab maintains a standing corrections process. Factual accuracy is essential to the utility of validation research, and we recognize that errors occur. Our goal is to correct genuine errors promptly and transparently, while maintaining the integrity of validation conclusions.

How to submit a correction. Correction requests are submitted to corrections@marketprooflab.com or through our evidence submission page. Submissions must identify the specific claim in question, the publication in which it appears, and the contrary evidence the submitter believes overrides our published claim.

Evidence standard for corrections. Corrections that affect validation conclusions require Class 1, Class 2, or Class 3 evidence as defined in the proof standards section above. Corrections addressing factual details that do not affect the overall validation conclusion — such as an incorrect date in a regulatory filing citation, or a mischaracterization of a certification's scope — may be supported by Class 4 evidence from a credible expert with disclosed credentials. Class 6 and Class 7 evidence alone is not sufficient to require revision of any published claim.

What constitutes a correctable error. A correctable error is a factual claim for which the submitter provides contrary evidence that meets our evidence class standards. Examples include: an incorrect regulatory filing date supported by the actual filing, an inaccurate description of a certification scope supported by the certification document, or a misattributed quotation supported by the original source. These are corrected.

What is not automatically revised. Validation conclusions, evidence weighting decisions, and editorial assessments of source quality are not subject to correction based solely on subject disagreement. If a subject disputes our interpretation of evidence, we note the disagreement and may append a clarifying note, but we do not revise validation conclusions because a subject dislikes the finding. We explain our reasoning in writing when a correction is declined.

Turnaround. We acknowledge correction requests within 5 business days and aim to issue a resolution within 10 business days of receipt. Complex cases may require additional time. All accepted corrections are reflected in the report's update timestamp and noted in the correction log at the bottom of the affected page.

AI assistance disclosure

Market Proof Lab uses AI-assisted tools as part of its editorial workflow. We disclose this clearly and without reservation.

How AI is used. AI assistance is applied at three stages: drafting initial prose from researcher notes and source summaries, summarizing lengthy source documents to surface relevant passages for human review, and formatting structured content such as evidence tables and section outlines. These uses reduce mechanical overhead and allow the editorial team to focus on judgment-intensive validation tasks.

How AI is not used. AI is not used as a primary researcher, a sole source of factual claims, or a substitute for editorial review. AI-generated text does not appear in published proof reports without review and approval by a member of the editorial team. No claim derived solely from an AI output is treated as verified. The proof standard applied to every published conclusion is identical regardless of whether a human or an AI tool produced the initial draft. AI tools are not used to assign evidence classes or render validation conclusions — those are editorial judgments made by the research team.

Why we disclose. Readers have a legitimate interest in understanding how our content is produced. AI-assisted drafting does not reduce our accuracy or proof obligations, but it is a material part of our process and we are obligated to say so. This disclosure is updated whenever our workflow changes in a material way.

What we will not publish

The following categories of content are prohibited in all Market Proof Lab publications, regardless of editorial pressure, submission source, or publication timeline.

Fabricated proof signals. We do not manufacture, invent, or misrepresent evidence of any kind. A certification that does not exist, a regulatory filing that was never submitted, or an audit that was never conducted cannot appear as a positive proof signal in any Market Proof Lab output.

Unverifiable market statistics. We do not publish market size estimates, growth projections, or adoption figures that cannot be traced to a named methodology and an accountable publisher. Figures that circulate in promotional materials without a documented origin are Class 7 items and are labeled as such, not published as market fact.

Invented case studies. We do not fabricate customer outcomes, deployment scenarios, or performance results of any kind. Case study evidence must be documentable and attributable to a real, named situation. Composite or anonymized case studies that were not drawn from documented real-world situations are prohibited.

Undisclosed commercial relationships that could affect validation outcomes. Any commercial relationship between Market Proof Lab and a covered organization that could affect our validation of that organization must be disclosed at the top of every page where that organization is assessed. Publishing validation conclusions about a covered organization without disclosing a relevant commercial relationship is prohibited.

Pay-to-validate placements. No organization may purchase a favorable validation conclusion, an improved proof classification, or any form of preferential treatment in a Market Proof Lab report. Commercial arrangements do not influence validation outcomes.

Invented citations and testimonials. We do not fabricate quotes, references, expert endorsements, or testimonials of any kind. All citations name their verifiable origin. We do not use composite or representative quotes that were not drawn from real, documented sources.

Vendor-written content presented as independent research. We do not publish vendor-supplied content as independent validation. If a subject provides documentation or factual corrections that we incorporate, that contribution is noted in source disclosures. Vendor-supplied text is not presented as Market Proof Lab editorial conclusions.

Claims outside the five proof classes. Any validation conclusion that cannot be anchored to at least one of the five proof classes is removed before publication. Conclusions resting solely on Classes 6 or 7 material do not meet our publication standard.

Page updates and versioning

Validation findings have a shelf life. Markets change, certifications expire, regulatory conditions shift, and new evidence emerges. Market Proof Lab maintains a versioning practice designed to make the age and revision status of every proof report transparent to readers.

Published and updated dates. Every proof report carries a published date and a last-updated date displayed in the report header. Readers should treat the last-updated date as the relevant reference point for assessing currency. We do not apply rolling timestamps that do not reflect genuine revisions.

Material updates. When new evidence changes a validation conclusion — such as a certification expiring, a regulatory action being taken, or a Class 1-3 document emerging that contradicts a published finding — we issue a material update. Material updates are noted at the top of the affected report with a summary of what changed and why.

Minor corrections. Typographic corrections, formatting fixes, and small factual clarifications that do not affect validation conclusions are applied with a revised update timestamp. These changes are logged internally and available to readers who request the revision history.

Report retirement. Proof reports that become outdated due to material changes in the subject's status, the regulatory environment, or the available evidence are marked with a prominent update notice explaining what has changed, what portions remain valid, and whether a revised validation is in preparation. Reports are not deleted; an outdated report that is removed from access is more likely to resurface uncorrected elsewhere than one that remains accessible with a clear disclosure of its limitations.
