paged.IDML Reference
The Paged PlatformCapability state

Capability matrix

The full capability grid — every paged capability across every implementation layer, with a shipped-and-verified status per cell. Generated live from the registry.

Tier: IntermediateIntermediateIIreference

In short every capability paged tracks, grouped by chapter, shown across the implementation layers it touches. Each cell's glyph carries the meaning — shipped and verified, shipped but untested, partial, failing, or planned — so the grid reads in greyscale. This page is generated from the capability registry; the support badge beside each IDML feature links here to its row.
