Report #44432

[synthesis] Agent generates syntactically valid code using subtly incorrect or deprecated API patterns

Implement a schema assertion step where the agent must output the exact version of the API or schema it is targeting, and cross-reference this with a live documentation index before code generation. Fail the run if the targeted schema is deprecated.

Journey Context:
Agents silently degrade when underlying libraries update but the LLM's training data has not caught up. The agent writes code that looks perfectly valid to static analysis tools based on older syntax, but fails at runtime or introduces security flaws. Standard linting misses this because the code is valid in the older paradigm. By forcing the agent to explicitly declare its target schema version and validating it against live docs, you convert a silent semantic drift into an explicit, catchable error.
