Gaps the research left open

10Shown as gaps, never filled in by guesswork. Supplement 1 (the second pass) closed some; they are listed below.

Budget 2026 (28 October 2026, today): the Budget document, speech and OBR forecast were not on GOV.UK at 13:20 UTC when this page was written; the 24 October press release is the only source for the AI package. The lead should re-check https://www.gov.uk/government/organisations/hm-treasury after the Budget. — Partly closed (Supplement 1): The Budget HTML document opened (both halves). Its AI lines match the master's ledger; the AI Challenge Prize is now known to be administered by DCMS (S1 MON-030, GOV-HMT-M15; GOV-HMT-028). New records GOV-HMT-026 to GOV-HMT-029. Still not opened: the Budget 2026 document landing page and the Budget speech (client errors), the full-print PDF and the policy costings PDF (binary). The HTML as fetched ends partway through Box 3.B (127,037 characters); any AI lines in later chapters of the document were not read, so the £30m local AI partnerships, £23m AI Economics Institute, £18m Chip Design Academy and £10m a year on jobs remain unconfirmed in the Budget document.
Budget 2025 (26 November 2025), Autumn Budget 2024 and the SR2025 HTML pages are longer than the fetch tool returns (each cut at about 125,000 characters), so their AI passages beyond the first sections could not be read; PDFs returned as binary. The SR2025 AI section was captured; the Budget 2025 and Autumn Budget 2024 AI measures were not. A 2026 spring fiscal event was not located via the search API ("Spring Statement 2026" returned only the annual report).
OBR AI analysis: obr.uk could not be opened (provenance block) and one web search returned no OBR pages. Not recorded. — Partly closed (Supplement 1): November 2025 EFO and July 2026 Fiscal risks report opened: GOV-HMT-024, GOV-HMT-025; S1 GOV-HMT-019. Still open: the obr.uk home page and the October 2026 EFO page (permission timed out), so the EFO accompanying Budget 2026 and its AI references are not recorded; the body text and figures of FRS Box 4.1 (the box page https://obr.uk/box/the-potential-impact-of-ai-on-the-labour-share-and-tax-receipts/ returned a client error, and the report page as fetched did not include the box text); OBR Briefing paper No.9 "Forecasting productivity" (PDF not opened).
Treasury "AI and productivity" work beyond the AI Economics Institute, the Mais Lecture and the Growth Speech (for example any HMT working paper) was not found.
The AI Economics Institute Prospectus, the AI Champions Terms of Reference PDF, the FS strategy One Year On PDF and the G7 cyber statement were not opened.
Government Actuary's Department: no AI activity found on its GOV.UK page; its actuaries blog (3 September 2026 transformation post) was not opened.
NISTA, UK Government Investments, the National Wealth Fund and the Evaluation Task Force were not checked for AI activity.
The date Rachel Reeves left and John Healey became Chancellor was not traced (Healey is Chancellor by 7 September 2026; Reeves gave the 17 March 2026 Mais Lecture).
Ministerial AI lines: Lucy Rigby is confirmed as Economic Secretary with the AI Champions; the Treasury minister responsible for the AI Economics Institute was not identified.
HM Treasury annual report: characters 100,000 to 131,664 were not read (likely contains the headcount and spend figures).
