TokenCap Enforces Zero Network Egress via Automated CI Sovereignty Tests

Developer tool TokenCap has implemented automated tests in its CI pipeline to guarantee that the tool makes no unauthorized network calls at runtime. The project enforces four strict rules: no runtime network requests, no API keys, no native compilation scripts, and a maximum of four production dependencies. Tests hook into Node.js network primitives and verify package manifests to catch any violations before code is merged. WebAssembly binaries are vendored directly into the package, allowing TokenCap to run in air-gapped corporate environments, firewalled CI runners, and defense systems without any outbound network traffic. The approach was adopted because the team behind TokenCap wanted security guarantees enforced by tooling rather than relying on individual developer discipline.
