[synthesis] Multi-agent handoffs drop failure signals — receiving agent treats all inherited state as equally reliable ground truth

Structure handoff messages to require explicit fields: \`assumptions\_made\`, \`steps\_not\_verified\`, \`partial\_state\_created\`, and \`confidence\_level\_per\_step\`; never allow a handoff without these fields populated; receiving agent must treat items in \`steps\_not\_verified\` as untrusted

Journey Context:
When Agent A hands off to Agent B, the handoff message is a natural-language summary. A naturally emphasizes what it accomplished, not what it was unsure about — this is the agent equivalent of normalization of deviance from organizational safety research. B then treats all received context as equally reliable. The compounding is insidious: B builds on A's uncertain output as if it were verified, C builds on B's output, and by the time the error surfaces, the chain of dependency makes it catastrophic. The fix forces explicit articulation of uncertainty at the boundary, making it structurally impossible to hand off without declaring what might be wrong — applying incident investigation handoff protocols to agent orchestration.
