A modeler can use trace checking to ensure the preservation of the model behavior during the refinement process. In this paper, we present a trace refinement technique and tool called BERT that allows designers to ensure the behavioral integrity of high-level traces at the concrete level. The proposed technique is evaluated within the context of the B and Event-B methods on industrial-strength case studies from the automotive domain.","authors_text":"Alexander Egyed, Atif Mashkoor, Michael Leuschel, Sebastian Stock","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LO","submitted_at":"2022-07-28T12:31:12Z","title":"Trace Refinement in B and Event-B"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2207.14043","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:8c849679474c6bdc27614315f8a9e2bd5f53c54565e42a8c57bafb0747861e14","target":"record","created_at":"2026-07-05T04:44:23Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"336e42444b9e51e5e0a45359564d708545d4cba3b38bcf203dd6303c10005de3","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LO","submitted_at":"2022-07-28T12:31:12Z","title_canon_sha256":"f0b1dace5e5e563a5cbd11972abb29cb29810f60bfd86391971ee225812de390"},"schema_version":"1.0","source":{"id":"2207.14043","kind":"arxiv","version":1}},"canonical_sha256":"99ae63c71d2cc9c83e5955ca768b3aefb08ff1234e4351e3b0c9ef3ea633000c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"99ae63c71d2cc9c83e5955ca768b3aefb08ff1234e4351e3b0c9ef3ea633000c","first_computed_at":"2026-07-05T04:44:23.841404Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:44:23.841404Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"cNJMYpnbMZSL79us6IfxsFiYl+6QtBoPriP92dl1UoAEDEzUdBQ22D1undKVf9OIn07+DhFkohXjchvTzHWMBw==","signature_status":"signed_v1","signed_at":"2026-07-05T04:44:23.841748Z","signed_message":"canonical_sha256_bytes"},"source_id":"2207.14043","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8c849679474c6bdc27614315f8a9e2bd5f53c54565e42a8c57bafb0747861e14","sha256:fc8c83db3246051052900df4d26c7c96376212ab7cabcabbdc3f71ade4db3553"],"state_sha256":"491d54165c4ce825a9eabef2eeff9b2ac0beb6a998dc2ff8f69e4277ce7b09e1"}
