| # IA Utils — Vector Sequence Healing | |
| Standalone module (`ia_utils/`, a separate top-level package alongside | |
| `dense_evolution/`) for cleaning sequences of vectors — e.g. hidden | |
| states, embeddings, VQE/MD telemetry — that may contain `NaN` or `Inf` | |
| entries, or spurious spikes that look like noise rather than genuine | |
| signal. `median_healing` and `enhanced_dense_healing_hybrid` both | |
| preprocess the input (Inf → NaN → column-mean imputation) before | |
| healing, so corrupted values never propagate into the output. | |
| ::: ia_utils.vector_healing | |

| **See also**: [`dense_evolution.healing`](healing.md) for the predictive | |
| "Phi-Trigger" primitives `enhanced_dense_healing_hybrid` calls internally | |
| to decide, per step, whether an observed change looks like genuine | |
| dynamics (kept as-is) or static noise (replaced with the local median). | |
| [`ia_utils.adversarial_vector_attack`](ia_utils_adversarial_vector_attack.md) | |
| for a gradient-based robustness test of that same Phi-Trigger decision. | |
