Abstract
To detect and effectively respond to damage to the cell envelope, Gram-negative bacteria possess multiple envelope stress responses. Among these, the CpxAR two-component system has been shown to sense the presence of misfolded periplasmic proteins and increase the production of envelope-localized protein folding and degrading factors in response. However, recent studies have revealed that additional parameters, such as adhesion and central metabolism, can also be sensed by the Cpx signalling system. The discovery that the Cpx regulon contains dozens to hundreds of genes indicates that the cellular functions of the Cpx response are also likely much broader than previously realized. These newly recognized functions include other aspects of envelope maintenance, communication with other regulatory pathways, and pathogenesis. A new model is emerging in which the Cpx response integrates diverse signals and promotes cell survival by protecting the envelope in multiple ways.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
