Report #102276

[synthesis] A handoff message between two agents drops the failure mode that the first agent already handled defensively

Define an explicit failure taxonomy in the handoff schema and require the receiving agent to acknowledge each failure mode, not just the success payload.

Journey Context:
In multi-agent systems, the instinct is to pass a clean result and maybe a boolean success flag. But booleans erase nuance: 'success=false' does not distinguish between 'file missing', 'permission denied', 'partial write', and 'network timeout' — each of which demands a different recovery. A richer schema feels like overengineering early on, but it is the only way to preserve defensive context across agent boundaries. The receiving agent should be forced to enumerate the failure modes it received and state its recovery plan before acting, rather than silently defaulting to a happy path. This is the agent equivalent of structured error types across service boundaries.
