Report #95314

[synthesis] Agent writes syntactically valid code that fails at runtime due to using deprecated API patterns from RAG context

Implement a secondary LLM-as-a-judge step that cross-references the retrieved RAG code snippets against the current package version constraints defined in the project manifest \(e.g., package.json or requirements.txt\) before the agent writes the code.

Journey Context:
Agents using RAG over a codebase will confidently use patterns from the vector DB. If the codebase updates its dependencies \(e.g., React 18 to React 19, or a Python library major bump\) but the embeddings aren't immediately refreshed, the agent retrieves the old, now-broken patterns. The code looks perfectly valid to the agent and passes static analysis, but fails at runtime. Just re-indexing on cron jobs isn't enough; you need a semantic check against the current dependency graph at generation time, combining vector retrieval mechanics with semantic versioning constraints.
