June 2025 monthly summary for OpenLIFU-python: Implemented granular per-transform approvals for virtual fits, enabling per-transform control over sonication parameters and enhancing risk management in fitting workflows. Refactored virtual fit results to store a list of (approval, transform) pairs per target, making approvals explicit and auditable. Updated downstream DVC tracking to align with the new virtual file (vf) result format, improving data provenance and reproducibility across experiments. These changes reduce configuration errors, improve traceability, and support more granular experimentation. All work is tied to the OpenLIFU-python repository and the feature set documented under issue #340. Commit references include 0c0a930b3351ace8f1e1e38ddc37b7d3a0d85b4f and c83a1337118e78051dc79b6c68eaef3d5f781ac9.
