 *
 * Behavioral assertions: invoke the staging/dispatch seam, inspect the staged

 *   Before the fix, dispatchKindEntry ignores the converter for agents kind and

 *
 * #1519 (Codex-only fix) was generalized here to ALL non-Claude runtimes on the
 * premise that GSD's worktree isolation was Claude Code's isolation="worktree"
 * spawn parameter, which no other runtime honored. #2584 replaced that premise
 * with the negotiated `dispatch.isolation` capability, and #2652 scoped the
 * use_worktrees stamp to match: a host declaring harness-worktree or
 * orchestrator-worktree keeps the `true` default, because stamping it false
 * pre-empts the negotiation and re-decides isolation by runtime name.
 *
 * All tests assert on the SUT's RETURN VALUE (engine output), not raw file reads,
 * except the parity integration test which carries the allow-test-rule exemption.
