Summary
Content-Security-Policy: frame-ancestors 'none'X-Frame-Options: DENYSecurity
Workshop is a local control plane. The UI can trigger daemon endpoints that launch local Codex/Claude/replay actions. Without frame protections, a hostile web page can embed
http://localhost:<port>and clickjack visible UI controls, turning user clicks inside the frame into same-origin daemon requests.Blocking framing removes that browser bridge while preserving normal local use. This is defense for the daemon/UI boundary rather than a claim of unauthenticated raw POST RCE.
