[architecture] Failures cascade because every agent assumes the previous agent succeeded

Treat every inter-agent call as a remote call with explicit failure modes: validate outputs, define fallbacks, and surface partial failures rather than masking them.

Journey Context:
Agents composed in a chain often pass their outputs forward without checking whether the previous step actually produced a valid result. One malformed JSON or empty response then poisons every downstream step. The robust design models agent calls like external API calls: validate the response against the expected schema, retry on transient errors with backoff, and decide explicitly whether to fail the workflow, degrade gracefully, or ask for human help. This is the same defensive posture promoted by Temporal for workflow activities and by structured-output APIs that refuse to return malformed results.
