FAQ: Five Myths About Free Models on Free Servers

Description and use

Developers often mistakenly believe that free models on free servers provide reliable, persistent, and secure environments. The author demonstrates how to capture receipts, verify persistence, protect secrets, and replay locally before CI integration.

Problem

Developers assume free models on free servers provide reliable, persistent, and secure environments, but evidence shows they lack proper ops, persistence, and security.

Outcome

By capturing receipts, verifying disk state, protecting secrets, and replaying commands locally, developers can confidently use free servers for scratch work while ensuring artifacts are owned, reproducible, and secure.

Workflow

• 1. Run helper script to capture receipt (exit code, hash, host, git head).
• 2. Verify file existence and git diff to confirm persistence.
• 3. Copy receipt to a trusted machine for ownership.
• 4. Scan repository for secrets before agent runs.
• 5. Pin tool versions and replay commands locally to confirm reproducibility.
• 6. Use the receipt and verified artifacts in CI pipelines.

I keep three columns for every repeated claim. They are claim, check, and corrected mental model.
