The safety controller has three fundamental components: a performance controller, a backup controller, and an assurance mechanism. The assurance mechanism uses a monitor, constructed as a finite state machine (FSM), to analyze a suggested performance control input and search for system trajectories that are bad prefixes of the system specification. A fault flag from the assurance mechanism denotes a potentially danger","authors_text":"Eric Feron, Matthew Abate, Samuel Coogan","cross_cats":["cs.SY"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SY","submitted_at":"2019-08-08T22:48:41Z","title":"Monitor-Based Runtime Assurance for Temporal Logic Specifications"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.03284","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":"sha256:7575a41fd597a316123c3e86929efa88f111bdb8269de7aabe8c00f114bbf0fd","target":"record","created_at":"2026-07-04T23:52:38Z","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":"652f1b0695f42ea33943e9fc89ee1b36e0f7e2c425a6d9a6d8e8ec32dd766c4d","cross_cats_sorted":["cs.SY"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SY","submitted_at":"2019-08-08T22:48:41Z","title_canon_sha256":"6ebcfbb85beab349f1b68963cb6dd229a950c7c2f72b4ee1ad2d7724ce214cb8"},"schema_version":"1.0","source":{"id":"1908.03284","kind":"arxiv","version":1}},"canonical_sha256":"4ed58559a97cb96dc0dfc4c191c9ac2f72eb598482627285a00b011b7c42b07b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4ed58559a97cb96dc0dfc4c191c9ac2f72eb598482627285a00b011b7c42b07b","first_computed_at":"2026-07-04T23:52:38.331820Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T23:52:38.331820Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"h7kNrNCmx6mZ2uS7yhLAS0ZOraPDpA3BWDJmmQ5ES1MIjGXzlXXOKKZYGmNj7N5P7Y5Nqv+b1ugN8gnSIP2bBw==","signature_status":"signed_v1","signed_at":"2026-07-04T23:52:38.332212Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.03284","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7575a41fd597a316123c3e86929efa88f111bdb8269de7aabe8c00f114bbf0fd","sha256:9ba3d95097dd75035746fc0088c3c86e1ec6bb90f7143f4d0f23c85b327b29e5"],"state_sha256":"710eb9f7ff99c7f5f8daa624566ecf9867b813a8c17d9d0d8bb5460006f92ee3"}
