Find First And Last Name Using Reg Ex

You craft a beautiful regex to extract first and last names for data redaction, test it on "Truman Donovan" and feel like a genius. Then you deploy it to production and discover it's also happily matching "Jeffrey Epstein" in email headers. Oops.

The regex is doing exactly what you asked—finding patterns that look like names—but it has zero concept of context. It can't tell the difference between "data that needs redacting" and "email metadata that absolutely should not be touched." Your regex doesn't care about your intentions; it just sees `\b(word)\b` and goes ham.

The real kicker? That monstrosity of a regex pattern `(?=.+\b(don\w+|d\.?)\b)(?=.+\b(truman)\b).*` with 15 matches and 874 steps is probably still missing edge cases like "O'Brien" or "José García" while simultaneously nuking your email headers. Classic regex overconfidence meets reality.
