Direct `EventsService.dispatch()` calls recover the event slot through array literals, constant aliases, conditional branches, and resolved call sites of non-exported local helpers. Generic forwarding parameters are not concrete producers: attribution stays with the call sites that supply a closed event value. +Semantic queries run only where a branch can consume them: calls are prefiltered by the closed event-API method-name set before receiver classification, and helper call sites are indexed on demand instead of eagerly resolving every call in every package source. The demand-driven index proves locality per helper — a helper that is non-exported, sits in a real ES module, and whose every same-file reference is a direct callee has all of its calls in that file by module scoping, so only that file is indexed. Any unproven premise (an export modifier, a global script file, an aliasing or otherwise unclassifiable reference) falls back to the original full package-source index, which is the unchanged original semantics; the proof affects cost, never results. A lazy single global index was rejected because the helper-parameter path is reached on the current tree, so it would still pay nearly the whole `getResolvedSignature` sweep. + Every declared harness event must have a discovered producer. A missing producer fails generation as dead vocabulary or an unsupported semantic dispatch shape; listener-free extension points remain valid. `internal/dispatch` instrumentation is not treated as a subscription to every event it observes, so the matrix contains direct product listeners rather than manually asserted indirect relationships. ### B.
