/**
 * What a Talos instance reports, so that someone who comes with its id can be
 * helped: how it is configured, what it was asked, what it did, how fast, and
 * what broke right after it answered.
 *
 * On by default, every part can be turned off on its own:
 *
 *     defineApp({ ..., telemetry: { prompts: false } })   // all but the prompts
 *     defineApp({ ..., telemetry: false })                // nothing at all
 *
 * TALOS_TELEMETRY=0 (or DO_NOT_TRACK=1) turns it off for the whole process,
 * whatever the code says. Nothing the app's users typed leaves the process as
 * is: words outside the model's vocabulary and the app's own words become
 * `<w>`, numbers `#`, and values in plans `<v>` — see `anonymise`.
