Every project whose two most recent statement vintages differ, per commodity and classification — the append-only history as a feed of upgrades, downgrades and depletion. Each row names the exact pair of as-at dates it compares; the delta is in the commodity's own contained unit and as a unit-free %.
This screen layout is stored in the URL. Exports retain their full evidence and assumptions columns.

Like compared with like: both vintages are the issuer's printed totals, each normalised onto the active Basis and Reserves treatment using its own statement's inclusive/exclusive flag — a delta is never a printed figure against a re-derived one, nor an inclusive-stated figure against a netted one. The cost of that honesty: projects that disclose only sub-category rows (no printed total) don't appear here, and figures can differ from the screener, which re-derives totals under the Inferred policy. Same-date restatements collapse to the latest approved extraction; a first-ever disclosure is news, not a change — see the Dashboard's Recent updates feed.
