Current public dataset: review 2026-09-16, with 22 source-dated products. Individual quote and check dates appear in the quote register.
September 16, 2026
Published a reviewed rate batch after the dry run and full site verification passed. Eleven observations were verified in the incoming collection; another seven Fidelity observations remained accessible only through their previously reviewed values, and four rate movements remained quarantined rather than being published. Vanguard and Schwab public quotes dated September 15 were published where the product, share class, rate type and date were confirmed.
The live CSV, comparison tables and calculator now identify September 16 as the dataset review date. Old product dates were not advanced when their source could not be verified.
September 13, 2026
Rechecked the Fidelity observations dated September 11 and advanced only their successful check dates. The published rates did not change. This maintenance confirmed that a current review can leave the public numbers unchanged.
September 11, 2026
Reviewed updated official Fidelity, Vanguard and Schwab quotes. The incoming source collection could not read the Schwab table, so those rows were recovered through a separate ordinary rendered-page review. Every imported movement stayed below the 0.25 percentage-point anomaly threshold. The calculator tests, build, source validation, SEO checks and independent financial fixtures passed before publication.
September 6, 2026
Launched the source-backed calculator with 22 products, explicit quote dates, prior-year tax percentages and visible uncertainty for incomplete municipal splits. Added the public CSV, methodology, coverage limits, correction channel and product comparison guides.
What a review includes
- Match the exact product and share class.
- Distinguish APY from seven-day yield.
- Retain the issuer’s source date separately from the date we checked it.
- Quarantine a large movement or incomplete source instead of forcing publication.
- Run calculation tests, source validation, page checks and a production build before publishing.
What this log does not claim
A successful source review does not mean a rate will remain available, that a product is appropriate for a reader, or that the tax treatment applies to every return. A failed collection does not prove an issuer stopped publishing a quote. Read the coverage limits and use the correction form to identify a source or calculation problem.
