I have it all backed up in Git, so as things evolve, there’s a paper trail and context.

We are back to the baseline. The availability of our tools isn't adding anything in the long term because the productivity increase we get from the tooling is negated by the time we're back to doing it the old fashioned way due to downtime, so there is no claimed productivity increase espoused by the pontificators of the tooling.
