Commit succeeded (warning about scope is non-blocking — event-bus isn’t in the scope enum, but core would be the standard scope; the commit still went through).

Summary

SPEC-33 complete. Added two diagnostic methods to TypedEventBus in src/core/event-bus.ts:

Method Signature Purpose
listenerCount() listenerCount<K>(event: K): number Returns handler count for a specific event
listenerCounts() listenerCounts(): Record<string, number> Returns all event handler counts

Key implementation detail: The plan’s code used this.listeners and .length, but the actual codebase uses this.handlers (a Map<string, Set<Handler>>), so the methods use .size instead.

Files changed:

  • src/core/event-bus.ts — +12 lines (two methods)
  • tests/unit/event-bus.test.ts — +31 lines (4 new test cases)

Verification: tsgo --noEmit clean, 12/12 tests pass.
