The data management platform can receive, from an AV at a first time, a first copy of a manifest including a creation history of a transformed object generated by the AV and a data integrity value corresponding to the transformed object. The data management platform can receive, from a second computing system at a second time, a second copy of the manifest. The data management platform can reconcile the first copy and the second copy. The data management platform can receive, from the second computing system at a third time, a request to upload the transformed object.

Abstract: Software code is tested to determine relative performance of the software code. Successfully executing a test may be used to flag problems in a code repository to be corrected or criteria for accepting code for acceptance to the repository. To further evaluate test results, the test may be run several times on the same code version to determine a test result stability score describing how the test results may vary in different executions, such as a frequency that the code passes the test. Based on the score, additional tests may be run to further refine test result stability score. To evaluate time-variance of testing, when a code version fails a test, a previous version of the code may be run with the same test and the results compared to determine if a new regression was introduced.
