Congratulations. It’s yours now.
Documentation? “Should be somewhere.”
One hour in:
You find scattered notes. No context. No history. Just comments like // handles edge cases.
Twenty-four hours in:
Tests pass. You understand less than when you started.
Every change feels like cutting the wrong wire.
This is normal.
It’s called code archaeology.
And it’s expensive.
Knight Capital Group lost $440M in 45 minutes.
CrowdStrike pushed a config no one fully understood.
The xz Utils backdoor incubated for two years.
Not reckless teams.
Just systems with no memory.
We broke down the six recurring pains of a codebase that forgot its own why.
