February 2025: Focused on stabilizing test data lifecycle in swift-nav/libsbp. Implemented a targeted bug fix so DeleteTestOutput deletion respects the RUST_SKIP_DELETE_TEST_DATA environment variable, improving test safety, determinism, and alignment with environment configuration. This change reduces risk of unintended data deletion during test runs and supports safer CI pipelines.
