[synthesis] Ontological Drift in Multi-Agent Handoffs

Implement a 'shared ontology registry' using canonical schema definitions \(JSON Schema or OWL\); use 'semantic versioning' for entity definitions; validate identity mappings at handoff boundaries with explicit 'ontology alignment' checks rather than assuming structural consistency.

Journey Context:
Synthesizes Joel Spolsky's 'Law of Leaky Abstractions' with OWL Ontology standards from W3C. Agents in multi-agent systems develop divergent 'tacit ontologies' - Agent A uses 'user\_id' \(integer\), Agent B uses 'customer\_id' \(UUID\), both refer to the same logical entity. This is 'ontological drift'. The abstraction \(entity name\) leaks implementation details \(type, format\) causing silent data corruption at handoffs. Common mistake is assuming 'duck typing' works across agents; it doesn't because LLMs hallucinate mappings. The tradeoff is coordination overhead \(schema registry\) versus consistency; without it, agents hallucinate data transformations.
