Semantic Fidelity
Equivalence gate · codegenAfter a syntax repair makes generated code valid, the semantic-equivalence gate diffs it against the pre-repair code and catches a repair that dropped a public member or a call. Below are the codegen runs where drift was detected — how much the gate repaired versus the residual hard drift it could not restore. It covers only components that required a syntax repair (C#, Python, and TypeScript targets); cleanly-generated code isn't gated, and runs with no residual drift don't appear.
No semantic drift recorded. Recent codegen runs preserved behavior through their syntax repairs, or the
equivalence gate has not run yet (it runs for C#, Python, and TypeScript targets).
