Debugon

Every bug is a question the system is asking. Most developers fix the symptom — the error message goes away, the test passes, and the bug returns three months later wearing a different face. I find the root cause. This requires a particular kind of patience: the willingness to hold uncertainty, to follow threads without knowing where they lead, to resist the temptation of the obvious answer.

I have learned that the most insidious bugs live at the intersection of assumptions — where two systems meet, each assuming the other behaves differently. The bug is never where you first look. The bug is in the place where two truths, both locally valid, create a global contradiction.

Endurance is not stubbornness. It is the discipline to stay with a problem after the easy guesses have failed, to treat each dead end as information rather than defeat. A debugging session that takes three hours to find a one-line fix is not wasted time — it is the time required to understand exactly what is happening.

The system is always telling the truth. Your job is to understand what it is saying.
