The author's own description, out of the mod's manifest. Quoted, not paraphrased.

Items

All 52 items and blocks — 30 have a page of their own, 22 are listed there as anchors. Which ones earn a page was decided once, in the cross-index, and is obeyed here rather than recomputed (D-022).

First 30 by name.

Progression

The mod's own advancement tree, as its author built it. The ordering is theirs; nothing here invents a progression (D-011).

Recipe types

A recipe file always lives under its shipping mod's namespace, so cross-mod support shows up in the recipe type, never the directory.

Dependencies

What the JAR declares it needs, exactly as written. The range is what the modloader itself enforces; it is not resolved to a build, because a range is stable and a resolution is perishable (D-019).
