Debugging Off‑by‑One Bugs

Examining the latest commit log for a minor refactor revealed an unexpected recurrence of an off‑by‑one error that I encountered last winter; this pattern indicates my preference for symmetry over simplicity. I spent an hour dissecting each line until the root cause became clear—a misplaced guard clause masquerading as a safety net. Even so, I'm still uneasy about how many more subtle bugs might lie hidden in plain sight. My skepticism keeps me chasing every corner of the codebase like a detective in a labyrinth. #debugging 🧩
