The JET compat cap `0.9, 0.10, 0.11` pins the QA job to JET 0.11.6 on Julia 1.13, which reports false-positive runtime dispatches for fully-concrete Base broadcast/materialize/iterate code (JET.jl#839, fixed in JET 0.12). With the cap in place, `jet_tests.jl` fails on the `julia '1'` lane (now 1.13.0) for `polynomial_basis`, `chebyshev_basis`, `fourier_basis`, and `_construct_datadrivenproblem`. JET >= 0.11.4 requires Julia 1.12, so the LTS lane keeps resolving an older JET and is unaffected. Verified locally on Julia 1.13.0: the four testsets fail under JET 0.11.6 and all 11 pass under JET 0.12.1.

Status note: the Core (julia 1, x86) failure is pre-existing on master (https://github.com/SciML/DataDrivenDiffEq.jl/actions/runs/34655428411 is red) — this PR only touches the QA environment's JET compat bound. |

Summary
The QA job on the
julia '1'lane (Julia 1.13.0) resolves JET 0.11.6, which reports false-positive runtime dispatches for fully-concreteBasebroadcast/materialize/iterate code on 1.13 (JET.jl#839, fixed in JET 0.12).test/qa/jet_tests.jlfails four@test_optchecks —polynomial_basis,chebyshev_basis,fourier_basis, and_construct_datadrivenproblem.This broadens the QA JET compat to include 0.12, matching the fix in SimpleDiffEq.jl#144. JET ≥ 0.11.4 requires Julia 1.12, so the LTS lane keeps resolving an older JET and is unaffected.
