/**
 * The character set stripped from any untrusted text the harness interpolates
 * into a message a model, a log, or a person will read.
 *
 * One definition, two call sites with different needs — a run interrupt's user
 * id (removed outright, so it cannot forge lines in the `[Interrupt from user
 * ...]` header) and a tool-argument path or name quoted back in a validation
 * failure (replaced with a space, so adjacent tokens stay separated, and
 * truncated). The *replacement* is the caller's choice; the *set* must not be,
 * because it is the security decision. Two copies means a future addition —
 * bidi overrides, say — lands in one and is forgotten in the other.
 *
 * Deliberately dependency-free: `@juno-ai/bind/loop` uses it, and that
 * subpath's module graph is kept free of runtime `zod`.
 */
