Describe the bug 🐞

Under specified compatibility bounds causing errors depending on resolved versions. My team has run into this issue repeatedly over the last few months; hopefully this specific example is clear enough to illustrate it. We have patched this on our end by pinning OrdinaryDiffEqLowOrderRK.jl to 1.10.0, but hope that there are fewer events where we change nothing and CI starts failing.

Is downgrade compat expected to catch this? Why wasn't there an internal major release for the API change?

Expected behavior

Not being able to resolve a broken set of packages owned by OrdinaryDiffEq.jl.

Minimal Reproducible Example 👇

Generated with Claude, tested manually.

# MWE for: MethodError: no method matching !(::Val{true})
#
# Root cause: OrdinaryDiffEqLowOrderRK 1.11.0 changed BS5's `lazy` field from
# `Bool` to `Val{Bool}`, but OrdinaryDiffEqCore 3.5.0 still calls `!alg.lazy`
# directly (expecting Bool) in `reeval_internals_due_to_modification!`, which
# fires whenever a ContinuousCallback affect is applied.

using Pkg

rm("Manifest.toml"; force = true)

Pkg.activate(; temp = true)
Pkg.add(; name = "OrdinaryDiffEqCore", version = "3.5.0")
Pkg.add(; name = "OrdinaryDiffEqLowOrderRK", version = "1.11.0")
Pkg.add(["OrdinaryDiffEq", "SciMLBase"])
Pkg.resolve()
Pkg.instantiate()

using OrdinaryDiffEq, SciMLBase

function f!(du, u, p, t)
    du[1] = -u[1]
end

# A ContinuousCallback that fires at t=0.5, triggering
# reeval_internals_due_to_modification!, which calls !alg.lazy
condition(u, t, integrator) = t - 0.5
affect!(integrator) = integrator.u[1] *= 0.9
cb = ContinuousCallback(condition, affect!)

u0 = [1.0]
tspan = (0.0, 1.0)
prob = ODEProblem(f!, u0, tspan)

# BS5() has lazy::L = Val{true}() in LowOrderRK 1.11.0
# !alg.lazy in OrdinaryDiffEqCore 3.5.0 throws MethodError
sol = solve(prob, BS5(); callback=cb, dt=0.1, adaptive=false)
