Hosted-CI checkpoint on amended head Representative root, documentation, and sublibrary jobs stop during dependency resolution because the current OrdinaryDiffEq master copy of These setup failures occur before the DelayDiffEq compatibility regression is loaded.

Agreed. I am replacing this compatibility-constructor approach with a registry retrocap. The locally identified boundary is OrdinaryDiffEqCore 4.8.1: registered DelayDiffEq 6.0.0–6.1.0 works with Core 4.8.0, while the new DEOptions layout starts in 4.8.1. I am validating a General compat split of |

Superseded by the registry corrections:
The final stacked registry resolution selected DelayDiffEq 6.1.0, OrdinaryDiffEqCore 4.8.0, and OrdinaryDiffEqDefault 2.4.0. The representative delayed problem then passed all 4 targeted checks through the public Closing this source-level compatibility constructor in favor of the reviewed retrocap direction. |

Summary
DEOptionsconstructor layout used by registered DelayDiffEq 6.1.0, supplyingtrivial_limiter!for the later-added stage and step limiter fields.init/solve!path and verifies both limiter fields.DEOptionstype to the rendered OrdinaryDiffEqCore API page.Root cause
c017e6c452883848ad86255de5ca3a1d033ebe83added two limiter fields toDEOptions. DelayDiffEq 6.1.0 still constructs the intermediate 21-type-parameter/41-argument layout, while the pre-existing compatibility constructor only covers an older 21-type-parameter/46-argument layout. The released package therefore hits aMethodErrorduringinit.The added constructor is backward-compatible and does not introduce or remove a public name.
