 - 14-03: PhaseDispatchManager methods use Phase suffix (queuePhase, completePhase) for clarity
 - 14-03: QueuedPhase includes initiativeId for context association
 - 14-03: PhaseDispatchResult simpler than DispatchResult (no agentId field)
+- 14-05: PhaseDispatchManager optional in context following existing pattern
+- 14-05: createPhaseDependency validates both phases exist before creating dependency
+- 14-05: getPhaseDependencies returns { dependencies: string[] } wrapper for API consistency
