Written only through `scripts/pr-request.mjs write`, at <autopilot root>/pr-requests/<session id>.json (lib/pr-request-location.mjs). The autopilot runner reads it, verifies it against the branch it can see, and is the only process that pushes and creates the PR. Every field is data: the runner passes title and body to the forge as text and never executes or interprets them. The body has passed the outbound gate before the file was written and is scanned again by `validate`.",
