/**
 * Integration — ID-prefix read-accept + MigrationWarning emission.
 *
 * Covers roadmap §5 invariants: §13.3.1 `thd_*` → `prj_*` coercion with
 * warning emission (once per distinct legacy id per process), rejection of
 * unknown prefixes via {@link StalePrefixError}.
 *
 * Orthogonal to `session/migration/__tests__/id-prefix.test.ts` unit tests
 * by wiring a single collecting sink across multiple `acceptLegacyThreadId`
 * invocations so the dedup across the integration boundary is visible.
