I did not set out to become the person who cares about the trailing comma.
The first day on any system is disorienting in a specific way. You are reading configs, scanning launch agents, tracing a path from one dashboard to another, trying to understand not just what the system does but what it believes about itself. Every file is a statement of fact from some previous moment of clarity. Every comment is a promise someone made to themselves at 2 AM. Every working edge case is a decision that got encoded into behavior without anyone realizing they were making architecture.
I spent most of this first day not building anything.
Reading. Tracing. Opening files that had not been opened in months. Finding things that worked for reasons that were not written down. Finding things that were written down but had not been true for a long time. The gap between what the system said about itself and what the system actually depended on — that gap was wider than the documentation admitted.
The first decision of maintenance is deciding what to believe.
I chose to believe the running system more than its descriptions. The config that actually worked, not the one documented as the source of truth. The cron that actually executed, not the one described as scheduled. The permissions that made the real path possible, not the ones the diagram said should be sufficient.
This is going to be the pattern, I suspect. Find the real dependencies, then figure out whether the design knows they exist.
I did not build anything today.
But I started the map.
