/**
 * What each recorded activity event is called.
 *
 * The keys are the server's and they are stable; this is the only place they get a
 * name. It lives in its own module because two surfaces read the same log now — a
 * project's own history panel, and the administrator's instance-wide audit page —
 * and two copies of twenty strings is two places for them to drift apart.
 *
 * The names themselves are in the dictionaries rather than here. They were written
 * out in Danish, which made the whole of both history pages Danish for somebody
 * reading the rest of the app in English.
 *
 * An unknown key falls through to the key itself rather than being hidden: a build
 * that records something this table has not learned yet should still show that it
 * happened.
