Alitheion

Is the count reliable?

The UN System of Environmental-Economic Accounting Ecosystem Accounting framework tells the world what to count. It does not tell the world whether the count is reliable. Alitheion is the truth-and-attestation audit layer that institutional adopters (UN Statistical Commission delegations, OECD reviewers, national statistical authorities, the Canadian Expert Taskforce on Natural Capital Accounting and Nature Financing, every Kunming-Montreal Global Biodiversity Framework signatory measured against SDG 15.9.1(b)) can cite when their SEEA EA accounts need a third-party reliability statement.

Alitheion does not produce SEEA EA accounts. We audit them. The audit is the product. Our role in the broader ecosystem is to be the independent attestation layer that says: yes, this country's natural capital accounts meet the published verification framework standard — or, no, here is specifically where the reliability claim does not hold and what would close the gap.

The SEEA EA reliability question

94 countries are implementing SEEA EA as of 2026. The SDG 15.9.1(b) scoreboard: 67 at Stage III (regular compilation and dissemination), 10 at Stage II (accounts disseminated), 17 at Stage I (compilation started). Every implementing country reports its account against Kunming-Montreal Global Biodiversity Framework commitments. None — in the published methodology we have surveyed — carries a third-party reliability attestation. The reliability question goes un-asked, even though it is the question every account user (downstream policymaker, monetary-valuation analyst, biodiversity finance investor) is implicitly making a working assumption about.

The audit primitives we apply

Empirical noise floor cross-check

Does the account's underlying measurement methodology carry an empirically-calibrated noise floor, or does it report point estimates without quantitative uncertainty bounds? Sigma-floor-style verification calibrated from independent peer measurements is the standard.

Cross-modality independence check

Are independent measurement modalities used to corroborate, or is the account built from a single observation source? Multiple independent modalities (satellite + ground sensor + reported record + transaction data) under cross-validation is the standard.

Refusing-false-confidence audit

Does the methodology refuse to publish confident values where the underlying signal cannot support them, or does it produce numbers regardless of measurement reliability? The TALL tower spatial-heterogeneity discrimination result (published in the Trellison-submitted LedgerWell Verification Framework paper) is the canonical example of this primitive working correctly.

Provenance chain audit

Can each released value be traced through the published methodology back to the underlying source measurement, with a cryptographic checksum at each computation step? SHA256-rooted DAG provenance is the standard.

Monetary propagation audit

Where SEEA EA Account 4 (Ecosystem Services Use, monetary) and Account 5 (Monetary Ecosystem Assets) translate physical stocks into monetary values, does the methodology preserve the conformal coverage guarantee through the propagation, or does uncertainty get lost in benefit-transfer extrapolation? The Canadian OCSA November 2025 report named this as the core methodological barrier.

Long-horizon integrity audit

For accounts that feed into long-tail valuation claims (carbon-removal permanence, multi-decadal ecosystem service projections), does the methodology carry cryptographic integrity at the relevant time horizon? Lattice-based PQC may not satisfy 50-year horizons; physics-floor arguments grounded in the Eastin-Knill theorem do.

What an Alitheion attestation says

An Alitheion attestation is a structured statement: which primitives the audited account satisfies, which it does not, and (for the ones it does not) what specific evidence would close the gap. We do not publish pass/fail grades that misrepresent the analytical depth. We publish the specific verification primitives the account currently meets and the specific ones a downstream user should not assume are met. The receiving institution then makes its own decision about whether the account is fit for its purpose.

Reference framework

The audit primitives we apply are documented in the Trellison-submitted LedgerWell Verification Framework methodology paper. The CVR Protocol Mathematical Framework Series provides the mathematical grounding. The companion SEEA EA 94-country verification-gap white paper documents the scale of the addressable audit market. Alitheion attests against the published standard; the standard is published, not vendored.

Engagement model

National statistical authorities, OECD Working Party on Environmental Information, the Canadian Expert Taskforce on Natural Capital Accounting and Nature Financing, individual SEEA EA implementing countries seeking third-party reliability statements: engagement is a defined audit scope, a fixed-duration assessment, and a published attestation. Per the Trellison institutional model, methodology evaluation is bounded; we audit what is in scope, we publish what we found, we do not extend conclusions beyond what the evidence supports.
