| Foundry’s public presentation layers adhere to a "Zero-Execution" mandate, eliminating client-side JavaScript for core DOM manipulation, language routing, and file serving. This architectural constraint minimizes the attack surface and guarantees SOC 3 compliance by relying entirely on deterministic files and native CSS state management. | Foundry’s public presentation layers adhere to a "Zero-Execution" mandate, eliminating client-side JavaScript for core DOM manipulation, language routing, and file serving.
