Report #83718

[architecture] Agent output is syntactically valid but semantically divergent from expected domain

Compute cosine similarity between output embeddings \(text-embedding-3 or E5-large\) and reference distributions; flag outputs with similarity < 0.75 for review, using clustering to detect mode collapse or topic drift.

Journey Context:
JSON Schema validation catches syntax errors but misses 'hallucinated' content that fits the schema. N-gram overlap \(BLEU/ROUGE\) is brittle to paraphrasing. Embedding similarity captures semantic equivalence. Tradeoff: requires embedding service and reference dataset maintenance; may flag valid but novel outputs.
