Content inside the fence cannot forge a closing line without guessing the +//! nonce, so it cannot "break out" and have following text treated as +//! instructions. A fence WITHOUT a nonce (a fixed string) is guessable and +//! therefore weak — every caller must pass a fresh [`random_nonce`]. +//! - `label` distinguishes what kind of block it is (e.g. `SOURCE`, `PAGE`, +//! `DIFF`); `index` tags one block among many (e.g. per-source answers). + +use rand::Rng; + +/// A per-call nonce: 12 hex chars (6 CSPRNG bytes). Enough entropy that +/// untrusted content can't guess the closing delimiter to escape its fence. +pub fn random_nonce() -> String { + let bytes: [u8; 6] = rand::rng().random(); + bytes.iter().map(|b| format!("{b:02x}")).collect() +} + +/// Fence `content` between nonce-bearing UNTRUSTED delimiters. +/// +/// Open: `=====UNTRUSTED:
