A changed audio context rejected an overfitted explanation
Bounded timing search and residual gain fitting could propose corrections; an unused second-clip context rejected a global-delay explanation that did not transfer.

Method
The third cycle expanded a finite diagnostic model with timing search and residual gain estimation, checking candidate explanations on an unused audio context.
Findings
- A global delay fit was rejected by the changed context. Unexplained pan remained a mismatch rather than being forced into the model.
- Ten added cases used 22 native observations, 44 native processes and 234 predictions. The suite reported 72 tests.
Limits of the finding
- The builder authored these cases; assessment was neither independent nor blinded.
- The methods are conventional search and least squares within a finite model. No algorithmic novelty, superiority or general causal diagnosis was established.
- Native rendering and downstream analysis are separate operations. Raw audio and private evidence are excluded.
