PR SciML#3983 added SciMLOperators to [extras] and the test target but not to [compat]. The Downgrade workflow floors uncapped test deps to their lowest registered version (SciMLOperators 1.15.0), which conflicts with the in-repo path sublibraries (OrdinaryDiffEqDifferentiation requires SciMLOperators >= 1.24.4), making the test-target environment unsatisfiable. Adding the compat floor fixes the umbrella Downgrade CI, red on master since SciML#3983.

Fixes the umbrella Downgrade workflow, which has been red on master since #3983 (first-failing commit
8e20cb18; last green8fc48e69).#3983 added
SciMLOperatorsto root[extras]and thetesttarget but did not add a[compat]entry. The Downgrade action then floors the uncapped test dependency to its lowest registered version (SciMLOperators1.15.0), which is unsatisfiable against the in-repo path sublibraries —OrdinaryDiffEqDifferentiationrequiresSciMLOperators ≥ 1.24.4(andOrdinaryDiffEqExtrapolation ≥ 1.24.3) — givingUnsatisfiable requirements detected for package SciMLOperators … no versions left.One-line fix: add
SciMLOperators = "1.24.4"to root[compat], matching the sublibrary floor.Scope: this addresses only the umbrella
Downgraderegression. The separate, chronicDowngrade Sublibrariesfailures (staleLinearSolve = "3.75.0"floors inconsistent with theNonlinearSolveBase 2.34.1floor) are tracked under #2972/#2977 and are not touched here.🤖 Generated with Claude Code
