[architecture] Implicit agent roles create responsibility gaps — no agent owns the task at the boundary

Make agent responsibilities explicit and non-overlapping. Define a responsibility matrix: for each task type, exactly one agent is the owner \(accountable\) even if other agents contribute. Encode ownership in a routing function, not just in documentation. Include a fallback agent that catches unassigned task types.

Journey Context:
When agent roles are defined loosely \('Agent A handles research, Agent B handles writing'\), edge cases fall through the cracks. Who handles 'research for the writing task'? Who handles errors from Agent A's research tool? Implicit roles create responsibility gaps where no agent acts, or duplicate effort where multiple agents act on the same subtask. The fix is a RACI-style assignment: for each task type, one agent is Accountable—owns the outcome—while others are Consulted or Informed. The tradeoff: explicit roles reduce flexibility for novel tasks that don't fit the matrix. Mitigate with a fallback or default agent that catches unassigned tasks and either handles them or escalates to a human. Without this, you will debug 'why did nothing happen' failures that are caused by every agent assuming another agent would handle it.
