Development record

The shared --route help (internal/surface/cli/route.go:86-91) says 'each invocation dispatches one', and it renders for disembark principles, press-release and review (docs/reference/cli/commands.md:1033, 1052, 1083). Run without its payload flag, each of those verbs runs its deterministic mode and dispatches no agent (delegatedAgent, route.go:73-78). It then refuses --route with exit 2 (route.go:115-120). Only graveyard, whose --lessons-json is required, always dispatches one.
