Informational only — readiness is judged against the target version and never changes with this report.

Read the element counts as a floor

31 profiles exist only in 2.2.1, and 1 only in 2.0.1. Those have no counterpart to compare against, so they contribute no element-level rows to the counts above — the element comparison covers the 17 profiles present in both versions. Both numbers are below; neither is a total on its own.

The 400 mandatory or must-support elements attributed to added profiles are counted from each profile’s effective element list. Where a profile ships no snapshot that list is reconstructed by merging its differential onto its base, so treat the figure as indicative rather than audited. Each row states its own basis.

Profile coverage

Profiles present in only one of the two versions. These carry no element-level rows in the catalog above, because there is nothing on the other side to compare them against.

Compared in both versions: 17
Added in target: 31
Removed from baseline: 1
Element obligations carried by added profiles: 400

What is shown, and what is left out

Every count in the explorer is complete — computed over all 320 element changes. The example rows a node expands to draw on a bounded, deterministic sample of 40, chosen so every kind of change and the most-affected profiles are each represented. The full set is reproducible from the two packages named below.

The digests identify the exact archives compared. There is no generation timestamp on purpose: the report is a pure function of those two archives, so regenerating it from the same inputs produces identical bytes.
