# Phase 9 / Plan 4 / WARNING-5: install order LOCKED in AppDelegate.swift.
#
# vision → agent → voice. Asserts the literal Task spawn lines for the three
# install subsystems appear in that strict order in applicationWillFinishLaunching.
#
# - vision must finish before agent because installAgent's orchestrator
#   constructor takes self.visionRouter (Plan 2) + the broadcaster's
#   frame-attach release subscriber needs frameAttachController.
# - agent must finish before voice because installVoice's adapters require
#   self.agentOrchestrator + self.turnTranscriptStore (both constructed in
#   installAgent — Plan 1 / Plan 4).
#
# In addition, voiceInstallTask MUST await agentInstallTask?.value before
# calling installVoice — otherwise the install order can race even though
# the spawn-line ordering is correct.
