Moves the bench clock forward by ms; call Bench.tick after to re-evaluate — advance itself never writes.
A token-bound sibling client acting as access — the bench's ONE identity seam, cached per identity with omitted grants defaulting to wildcard; bind it to createBenchEngine instead of hand-rolling addIdentity + withConfig.
Current bench clock reading (ISO); wall-clock until BenchState.setNow or BenchState.advance freezes it.
OptionalresourceFreezes the bench clock at an explicit ISO instant; every subsequent engine call sees this as $now and stamps it on history.
The bench-owned engine call context injected into every wrapped verb.
