/**
 * Directory entries for the conversations a surface has ALREADY talked to.
 *
 * Every channel adapter upserts a route binding on ingress carrying the
 * originating channel/thread, so an entry exists here for any conversation
 * that has ever sent a message, with no configuration whatsoever. The
 * optional per-surface config fields (`defaultChatId`, `botUsername`, and
 * their equivalents) exist to INITIATE contact with somewhere nobody has
 * written from; gating the whole provider directory on them is what let a
 * fresh install receive messages and offer no target to answer them with.
 *
 * Kept beside targets.ts rather than inside it so the per-surface directory
 * lookups stay readable: this is one rule, applied identically fourteen times.
