/**
 * Format the `[info] [authority-index]` daemon startup line from the agent's
 * authority-index bootstrap plan.
 *
 * Extracted to a pure function so every plan can be unit-tested without
 * standing up a daemon. Operators grep this line, so its field order is a
 * contract:
 *
 * - an operator `authorityIndex` block (pinned trusted cores) and local
 *   history (a core, or an edge that cannot seed) keep the pre-10.0.18 shape;
 * - the network-relay edge default adds its trust source and the
 *   local-history fallback it degrades to when no relay supplies a usable
 *   snapshot inside the bootstrap budget.
 *
 * The input is structural rather than the agent's `AuthorityIndexBootstrapPlan`
 * so this module has no transitive imports; that type is assignable to it.
