rotcert: angle-aware conformal certification for oriented object detection

Abstract

Code and frozen result records for rotcert, an angle-aware distribution-free conformal certification method for oriented (rotated) object detection in aerial imagery. rotcert scores oriented detections with a seam-continuous, square-safe Gaussian–Wasserstein distance (GWD) nonconformity measure and issues two certificates: G1, a Mondrian per-class GWD-ball localization certificate with a finite-sample marginal-coverage guarantee, validated out-of-sample over R=20 scene splits; and G2, a Learn-then-Test Hoeffding–Bentkus certified bound on the rotated-IoU false-negative rate that refuses below its power floor rather than emitting a number it cannot support. GWD is consumed as a nonconformity score, not proposed as a new detector loss. The contribution is a reliability-certification protocol for oriented detection, not a new detector. Evidence is frozen and scoped: ten G1 cells across three aerial datasets (DIOR-R, DOTA-v1.0, HRSC2016-MS) and five detector architectures. All 20 DIOR-R classes certify for G1. DOTA overlapping crops are a diagnosed exchangeability stress case, running roughly 1–1.2 points below nominal. Archive contents. The rotcert package and its test suite, the detector and orchestration configs, the DOTA and DIOR-R certificate and inference result trees, the coverage-matched and per-class ablations, the HRSC seed cells, and the Holm-8 analysis records. DATA_MANIFEST.md describes the datasets and their provenance; SECURITY-PATHS.md documents path hygiene. Reassembling the archive. The tarball is deposited in ten 5 MB parts to work around an upload size limit. Concatenate them in order and extract: cat rotcert_zenodo_v0.2.0.tar.gz.part* > rotcert_zenodo_v0.2.0.tar.gz sha256sum rotcert_zenodo_v0.2.0.tar.gz # expected: 7f361f415422bcb892bee5543a752b8aa6abfde335f556aa60d6d8568b629d7c tar -xzf rotcert_zenodo_v0.2.0.tar.gz Changes since 0.1.0. Internal planning and review documents, editorial process notes, and manuscript sources have been removed from the archive; it now contains only the software snapshot and the frozen result records that the manuscript's provenance comments cite. Workstation absolute paths in result provenance fields were replaced with a placeholder, and CITATION.cff is now included. No scientific result record was altered.
