Thiago and Karime had talked one faction of the colonists into sending us a copy of the software on their main medical unit, and ART had removed any traces of contaminated code and modified its own decontam package to run on old shitty equipment. Then each unit had to be individually accessed and reloaded with the cleaned and enhanced operating systems via elaborately overcautious procedures to eliminate cross contamination or recontamination. Mostly in case we had fucked up massively and there were dormant virus fragments in play somewhere in the medical systems whose behavior didn’t match the human-machine-human transmission pattern we had previously noted.
