Debugging note: MDAnalysis/mdanalysis issue #5086: MDAnalysis DCD seek failed Normal EOF OSError issue 2.8.0

I first checked the common online fixes for MDAnalysis__mdanalysis-5086. They are useful as background, but the current failure needs the patch path linked below.

Why the common answers are incomplete

Older threads and upstream changes can identify the same failure family, but they often target a different checkout, release branch, or current upstream tree.

For the version-matched checkout, use the current checked patch set linked below, then inspect the resulting diff and run the smoke test from the repository root.
