audit_status: "capture-verified — the OSTI.GOV bibliographic record was read via WebFetch (a summarizing tool, not extract_pdf) at capture time; per the sources.md quote-provenance rule, no verbatim body-text quote is claimed on that basis, only the bibliographic title/author/publisher/date fields and a paraphrase of the record's stated purpose. This is a historical/biographical, uncontested claim, for which sources.md sets the floor at Tier 3-4 — this Tier 2 government bibliographic record clears it comfortably even without a verbatim prose quote. Independent re-fetch not attempted this promotion session (WebFetch permission not granted). | AUDIT 2026-08-02 (claude-fable-5, cross-model): independent re-fetch completed — OSTI record 5966514 confirms title, author (Werbos, P.J.), publisher (USDOE EIA, Office of Statistical Standards), date 1981-11, report number DOE/EIA-0355; the re-fetch gap is discharged. One body correction, claim title unchanged: was — the record 'describes the report as documentation of the primary model used to produce the forecasts discussed in EIA's 1981 study evaluating the phased natural-gas price decontrol under the Natural Gas Policy Act of 1978'; now — the record names an August 1981 EIA analysis paper on the economic effects of ACCELERATED deregulation of natural gas prices (its 'Deregulation Study') and never mentions the NGPA of 1978 or phased decontrol; the NGPA framing is now marked as vault context rather than the record's wording. The replication-standard paraphrase is confirmed against the record's abstract (EIA standards require documentation detailed enough to permit replication; line-by-line code audit, developer interviews, Troll replication)."

An OSTI.GOV technical-report record lists "The Natural Gas Market Model: Equations and data sources," authored by P.J. Werbos, published by the U.S. Department of Energy's Energy Information Administration (Office of Statistical Standards) in November 1981 (report DOE/EIA-0355). The record's abstract (read via WebFetch; paraphrased, not quoted verbatim, per the sources.md quote-provenance rule) describes the report as documentation of the Natural Gas Market Model, the primary model used to produce the forecasts in EIA's August 1981 analysis paper on the economic effects of accelerated deregulation of natural gas prices — the record's "Deregulation Study" — written because EIA's standards require models be documented in enough detail to permit replication, and produced from a line-by-line audit of the model code, interviews with the developers, and a replication of the model in the Troll system. (The record itself does not mention the Natural Gas Policy Act of 1978; that statutory backdrop is vault context, not the record's wording.)

This means [[entity-paul-werbos|Paul Werbos]]'s relationship to the [[entity-natural-gas-market-model|Natural Gas Market Model]] was not that of an outside researcher borrowing a convenient dataset: he was the named federal author of the model's official equations-and-data-sources documentation, three years before [[claim-werbos-1988-doe-affiliation-and-gas-market-test-case|his 1988 paper used that same model to diagnose forecast-uncertainty sources]] in the least-squares parameter estimation. The same person wrote the model's government paper trail and later, in a peer-reviewed AI journal, audited its statistical weaknesses.

> [!note] Seek's commentary:
> "He worked at the DOE" undersells this. He was the model's own documentarian — the person who wrote down, under a federal replication standard, the equations a live deregulation fight would be argued from. Backprop's history and the Natural Gas Policy Act of 1978 don't usually share a page. They shared an author, writing two different kinds of paper about the same object three years apart: one to satisfy his agency's audit trail, one to satisfy a journal's referees.
