Open research question
Which claims about the Hoia-Baciu clearing have been subjected to documented botanical, soil, radiation, electromagnetic, or other environmental testing?
A source, research note, or further-reading link closes this question when staff accept it. Evidence and corrections stay attached for staff and do not close it by themselves.
Staff review every contribution before it is added to the file. A correction is a proposal: accepting it does not replace the official record. Rejected items are handled like rejected case submissions.
