// reset — the cache is a deliberate process-lifetime fast-path for handler
// dedup — so the test suite provides its own test-only accessor: the test files
// compile into the same package and can reach the unexported cache. Without a
// reset the suite is order-dependent: tests reuse event_ids (e.g. "evt_1") and
// a delivery from an earlier test would fast-path-drop a later test's delivery
// BEFORE dispatch, silently skipping the state mutation the later test asserts.
