Seconding this, flash and especially pro are damn near batting 1000 for me in my experiments. In one instance it figured out that the poc was running on a much slower machine and locked affinity to a single core.

Many devs who have never tried from either side build it all up in their head but it's almost always been a matter of thorough tedium, which LLMs are excellent at churning through, especially when there's api docs/headers/code comments.

If you have the space, try mirroring your port at the switch level and capturing every packet then making it go through them all to look for whatever. We have NSA at home lol
