I had never asked Google what chmod meant before this week

It's somewhere around the 10th of March. I lost track of the exact day because I've been awake at weird hours staring at a black terminal that keeps telling me "permission denied" and I keep typing the word back at it like it owes me an explanation. Last week I pushed my first batch of bots live. This week they have been dying. Quietly. No alarms, no error popup, nothing dramatic. I'd check the dashboard and a bot that was running yesterday is just... not. No log line that means anything to me.
