Operational Guidelines (OG-001..OG-010)

Ten Operational Guidelines that codify methodological domains.

Strawman. Phase 1 ships the one-line summaries with expandable bodies. The full OG documents (.docx + .md) live in the gated /deep-dive/ section. Final text will replace these placeholders once the OG content packet is delivered.

Operational Guidelines

The 10 OGs codify FAND’s methodological decisions in a single place. Each is a self-contained guideline that an institutional reviewer can reference without having to read the entire framework. Together, they signal that this is peer-grade work — opinions about edge cases are written down, not vibed.

The 10 guidelines (placeholder one-liners)

• OG-001 — Source ladder discipline. Tier 1 (authoritative agency) → Tier 2 (compiled aggregate) → Tier 3 (researcher estimate) → Tier 4 (model fallback). Every published number records its tier.
• OG-002 — Ratio-splice protocol (S287). All multi-source splices use ratio-splicing, never butt-splicing. Codified in parameters.json.
• OG-003 — Produced-asset pedigree. OECD Source A as anchor; PIM for countries without direct OECD data; 4-tier source ladder; 211 countries covered (per State of FAND §4.1).
• OG-004 — PPP conversions. When to use PPP, when to use Atlas USD, when to use market exchange rates. Currently the default is Atlas USD for cross-country comparability.
• OG-005 — Cross-border per-side discipline. CBA and CBL are independent stocks. Never net. NIIP node excised (S220).
• OG-006 — HR production function (S278/BT-045). ln(RW_pc) = α + β₁·MYS + β₂·min(LE,65) + β₃·t. Coefficients live in hr_regression_coefficients.json — that file is always authoritative; older briefings citing different coefficients are superseded.
• OG-007 — Natural Capital aggregation. NC covers only Hohfeldian first-order claim-rights. Mangroves and hydropower classify under SR, not NC. The nc_aggregation flag in what_code_manifest.json enforces this.
• OG-008 — Intergenerational liability scope. 1.2.2 is structurally empty at TL1 (no national statistical system reports it). Populated only at FIPS=00000 (US bottom-up).
• OG-009 — Coverage dashboard discipline (S170). Automated regeneration at every session end; not optional.
• OG-010 — Two-version architecture for the US (S314). ISO3=USA (top-down, internationally comparable) and FIPS=00000 (bottom-up, jurisdiction-enriched) coexist. API distinguishes by identifier system.

Where the full text lives

The complete OG documents (one .docx and .md per guideline) live in /deep-dive/ for institutional reviewers. The one-paragraph expansions for each OG land in this accordion when the content packet arrives.

(Placeholder. Replace with the OG content packet per the dev brief §10. The above one-liners are paraphrased from the State of FAND briefing — they will be sharpened by John for the final.)
