This annex lists recent items of primary-source evidence (2024-2026) that postdate or refine the argument of the present work. Each item is attached to the functional pillar it supports and to the limit that prevents any over-interpretation. The full screening database — two hundred items covering twenty families, each accompanied by an explicit verification status — is held in a separate research notebook; only those references individually verified against the source are cited here, each being listed in full in the References.¶ 1

Measurement (HuIB). Two developments confirm a convergence on the need for a permanent measurement institution that has yet to be created. The Secretary-General’s Independent High-Level Expert Group on Beyond GDP has proposed a compass of complementary indicators (United Nations, 2026), an acknowledgement at the highest level that no permanent scientific body discharges this function; and the FAO’s true cost accounting has put the hidden costs of agrifood systems at some twelve trillion dollars a year, of which some eight trillion are health-related (Food and Agriculture Organization, 2024) — a figure to be read as illustrative and non-additive, precisely the discipline that HuIB is designed to impose.¶ 2

Rating (GIRA). Recent work shows that private rating decisions govern fiscal space: a late-2025 revision of the treatment of the callable capital of the multilateral development banks released, through a single methodological choice, a substantial volume of additional lending capacity (Cash, 2025), while a dedicated reform programme sets out how the rating function could be made accountable (Cash and Khan, 2024). It is this channel — and not a model to be admired — that the separation between rating and pricing effected by GIRA seeks to render contestable.¶ 3

Pricing and equity (GFEA). The coordination pathway that the present work posits is now concretely on the table. A proposal for a coordinated minimum effective rate on ultra-high-net-worth individuals shows that a tax standard can begin with a coalition of the willing and a collector of last resort rather than with a universal treaty (Zucman, 2024); and a quantitative analysis of the fifteen per cent global minimum tax documents the extent to which its effective yield is diluted in practice (Hugger et al., 2024) — together, these works make the case for an equity authority whose function is distinct from pricing.¶ 4

Border adjustment (BFM). A quantitative trade model using plant-level data shows that a well-designed carbon border adjustment can curb carbon leakage without disproportionately penalising low-income partners, but only under a specific design and largely for steel and aluminium (Clausing et al., 2025) — which is why the Border Fairness Mechanism must add what a border tax lacks: redistribution, consent and broader coverage.¶ 5

Financing (GSF). The recent replenishment rounds of the main vertical funds have systematically fallen short of their target (Madan Keller et al., 2024) — an empirical confirmation that a purely financial mandate, detached from the rest of the accountability chain, cannot balance its budget without sacrificing either thematic rigour or geographical equity.¶ 6

Spillover effects, revisited. Two 2025 studies refine the monetary spillover mechanism at the heart of Section 9: demand for safe assets and the global dollar cycle transmit United States conditions asymmetrically to emerging economies (Allen et al., 2025), and the intensity of that transmission runs through the role of the dollar (Acharya et al., 2025). These two works frame — without demonstrating it — the attribution discipline of the present work.¶ 7

Adjudication (Court). The 2025 ICJ advisory opinion confirmed the existence in international law of binding reparation obligations (International Court of Justice, 2025), a reading confirmed by subsequent legal analysis (Foster, 2025); and the 2026 review of climate litigation shows sharply rising litigation demand (Grantham Research Institute on Climate Change and the Environment, 2026) — to be read as evidence of a demand for adjudication, not as a mechanical demonstration that a new court is necessary.¶ 8

Democratic certification (IPDA) and AI. The Independent International Scientific Panel on Artificial Intelligence has moved from “established” status to its first published report (Independent International Scientific Panel on Artificial Intelligence, 2026), and the Secretary-General’s advisory body has recommended distributed and complementary mechanisms rather than a single global regulator (United Nations High-Level Advisory Body on Artificial Intelligence, 2024) — a direct precedent for the single-mandate logic, provided that the present work does not claim that the United Nations endorses the 7+3. On the civic side, the analysis of global citizens’ assemblies identifies the addressee gap — an assembly with no named institutional addressee and no obligation to respond remains purely consultative (Democracy International and Democracy Without Borders, 2025) — to which the present work responds with three rules: a named addressee, a reasoned response, a public deadline.¶ 9

Theory of the architecture. Regime-complexity analysis presents the 7+3 as an architecture designed to manage interface conflicts — separate mandates, collision rules, arbitration — rather than as a super-agency (Kreuder-Sonnen, Schmotz and Zürn, 2025). Combined with the literature on orchestration in development governance (Cormier, Heinzel and Reinsberg, 2024) and on the accountability of global governance (Lall, 2025), it supplies the vocabulary of delegation and accountability that the argument requires.¶ 10

A useful counter-example. Finally, the 2026 decision of the World Bank Group to integrate its independent accountability mechanisms (World Bank Group, 2026) constitutes both a precedent of reform by incorporation and a warning: the present work distinguishes the administrative integration of neighbouring procedures from the concentration of incompatible functions against which its principle of “one institution per function” warns.¶ 11
