Method

The passport chain. A loader fetches each release from the source’s own API or file. The raw response is archived with its SHA-256 hash, and every value stored from it carries a passport: the archive path, the hash, the retrieval date and the source URL. A value with no passport cannot be published; the export refuses it.

Revisions. When a source revises a figure, the new value is stored beside the old one with its own passport. Pages show the latest; the release log records every landing, including revisions found by the nightly run.

Rounding. A value is shown to the number of decimals the source published, and is rounded before any scaling. Changes are computed from the rounded figures the release printed.

Status. A hollow square marks a figure the source flagged as preliminary. A filled square marks every other figure: final, revised, or as published (the source set no flag). The table under each chart prints the word beside the square.

Charts. Drawn at build time from the same data as the table beneath them; the table is the accessible form. The dotted line is the series median. No scripts run in your browser.
