D2 Chaining Evidence — Natural Multi-Type Combinations

Evidence collected during Phase 2I-4 first compilation run (2026-03-25).

Findings

Element	Chain Pattern	Evidence
ax19	ax-logic-limit	ax19 (Leviathan Chain) naturally combines axiomatic content with logic (measure-zero uniqueness argument) and limit (epistemic identification not claimed). The content wants all three D2 concepts simultaneously: the axiom, its logical defense, and its known limitations.
ax11	ax-logic	ax11 (Dipolarity) combines the axiom with the ax11/ax11b fork, which is a logic-level analysis. The PoR presents both as a single entry, but they are conceptually two D2 types chained.
ax14	ax-logic	ax14 (Revelation Claims Test) has both an axiom component and a logic component (the no-self-reference design, the claim(p) predicate distinction). These are naturally chained.
ax24	ax-limit	ax24 (Life-Trifecta) combines the axiom with its known limit (the three predicates lack formal semantics). The limit is integral to understanding the axiom, not a separate concern.
th8	th-logic-limit	th8 (Binary Attractors) chains theorem, logic (absorbing CTMC model, Michaelis-Menten analogy), and limit (falsification framework not yet specified). Three D2 types in a natural chain.

Summary

Natural D2 chaining emerged in 5 of 32 elements. The most common pattern is ax-logic (axiom + its logical defense), followed by ax-limit (axiom + its known limitations). th8 showed the deepest chain (th-logic-limit). The current default nesting limit of 2 is sufficient for observed cases. The 3-deep th8 case could use the .. best-depth:: 3 override if needed.
