// The town-crier leg's own tests, moved out of core's announceJobs.test.js in
// Phase 3 (MODULE_SYSTEM.md §2.7.1).
//
// Core keeps what it owns there — the backoff schedule, the parent-status rollup
// and the Discord leg — because those are the announce PIPELINE. What is here is
// this module's LEG: how a post becomes town-crier lines, and how the sidecar's
// answers classify into done / retry / terminal. The split is the same one the
// registry makes.
