. The paper reports no new human or animal experiment.

and code availability. The supplied source snapshot is identified in Cheung068Code. The analytic examples require no empirical dataset. The appended code is a compact proposed repair core, not an executed reproduction of the original experiment.

provenance. The work contains analytic arguments, a static source audit, and unexecuted repair listings. Compilation, numerical regression, formal proof checking, and biological validation are separate activities. No artifact hash, executed pass flag, or reproduced performance table is invented.

boundary. The paper does not advise selecting, combining, discontinuing, or timing antidepressant treatments. The source's drug-class names are limited analogies for computational operations, not treatment recommendations.
