To identify the degree of reusability between these different occurrences of a component, it is necessary to determine the functional backward and forward compatibility between them. Based on this information it is possible to identify in which system context a component can be replaced safely by another version, e.g. exchanging an older component, or variant, e.g. introducing new features, to achieve the s","authors_text":"Bernhard Rumpe, Christoph Schulze, Jan Oliver Ringert, Michael von Wenckstern, Peter Manhart","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2015-11-17T11:49:36Z","title":"Behavioral Compatibility of Simulink Models for Product Line Maintenance and Evolution"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.05358","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:aa30d2cec1faa3a01bb45575e86a52de14d5b2a8beb09dfec2f2e35c14739739","target":"record","created_at":"2026-05-18T01:26:40Z","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":"af4b264cf9ff809ec131cacfc6012b32d4185c2ecdf5ffaa6417a8cb975db302","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2015-11-17T11:49:36Z","title_canon_sha256":"3e4ac6052aa31709e8daa9ba5f339e9b279ec9f4e70d2855476a69a9f3b1471b"},"schema_version":"1.0","source":{"id":"1511.05358","kind":"arxiv","version":1}},"canonical_sha256":"1be30041ae7adf116a02a26fc15c9bc71a3bf8bb6d780e0d1e5fc5949e8adc79","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1be30041ae7adf116a02a26fc15c9bc71a3bf8bb6d780e0d1e5fc5949e8adc79","first_computed_at":"2026-05-18T01:26:40.535090Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:26:40.535090Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"o2Wr2qi8dbHGlFIV4yJoYdtFurlimrk/qlfZJpcBqVKLy6IDtLS6WXk0/xZ52esdP+XkeGQs2Tzs1P6lZUGuCA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:26:40.535738Z","signed_message":"canonical_sha256_bytes"},"source_id":"1511.05358","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:aa30d2cec1faa3a01bb45575e86a52de14d5b2a8beb09dfec2f2e35c14739739","sha256:de6fd188b1d2128dce09d46a63eb37012187eab1231a23b462ab30662f5739e1"],"state_sha256":"edef0baacf1090d063978d3e54d43934adf1ef6308f680d2a33be0ed95e45d85"}
