At 3:00 AM, a ping echoed through her headset. A remote script was attempting to scrape her environment variables. The intruder found her .gitignore and saw that .env.vault.local
Because the file ends in .local , it is automatically ignored by many default .gitignore configurations (like the ones provided by GitHub for Node.js or Python). Even if it isn't, the convention implies: This file stays on my machine. .env.vault.local

It allows you to decrypt the production vault, but immediately override specific variables for local debugging without touching the encrypted file.
