CI Analysis

The Downgrade CI workflow is failing, but this is not caused by the Functors 0.5 update itself.

Findings

1. Functors 0.5 compatibility works - The package loads and runs with Functors 0.5, producing deprecation warnings but no actual errors.

2. Test timeouts - The 6 errors in the DeepBSDE tests appear to be due to timeouts during execution, not assertion failures. These tests involve complex Zygote AD compilation that takes significant time.

3. Deprecation warnings - The following deprecated Flux APIs are being used:

   • Flux.@functor in src/NNStopping.jl:50 (should use Functors.@functor or remove entirely since Functors 0.5 makes structs opt-out)
   • @functor without qualification in src/MCSample.jl:16,39
   • Flux.params() in src/DeepBSDE.jl:113 (deprecated, should use Flux.trainable())
   • Flux.train!(loss, ps::Params, ...) in src/DeepBSDE.jl:193 (deprecated, should use explicit-style training)

Recommendation

This PR can be merged as-is to add Functors 0.5 compatibility. The deprecation warnings don't prevent the code from working.

A follow-up PR should update the deprecated Flux APIs to the new explicit-style APIs to:

• Remove deprecation warnings
• Potentially improve compilation times
• Prepare for future Flux versions that may remove these deprecated APIs
