You're right, no firm answers, but my suspicion of problems associated with the bleach and/or fix remain in place. What I think I see mostly in your negatives are clear signs of fogging patterns and the likely culprit is downstream of the developing step in the process.
For the very cyan base of the Portra, I still lean towards xray problems since the fog is so dense and the problem is reminiscent of e.g. Chinese parallel import Portra film that we saw a little over a year ago.
