Cobra provides both an easy way to present proofs and a novel approach to auditorium interaction. The presentation is checked live by the theorem prover, and moreover allows for live changes both by the presenter and the audience.","authors_text":"Christoph L\\\"uth (DFKI, Martin Ring (DFKI), Universit\\\"at Bremen)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2017-01-25T01:21:43Z","title":"Interactive Proof Presentations with Cobra"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1701.07127","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:e9c22099db7c0bcb4ecc73a63dc467696ec7cc6a4768e2fb81c7af00446c06cb","target":"record","created_at":"2026-05-18T00:52:07Z","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":"09c67745a86f687cba554a323ff78d701d8310a2b2acf36c2e0c10828a812845","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2017-01-25T01:21:43Z","title_canon_sha256":"8e278509e8d6ba2ee446f86fb65b1209a80c772b99f380bef01195c2a65eaa07"},"schema_version":"1.0","source":{"id":"1701.07127","kind":"arxiv","version":1}},"canonical_sha256":"3f5a4fd49a8b00afc6210589ac7fb6a5402c6567788f2bb667782cc6f860989d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3f5a4fd49a8b00afc6210589ac7fb6a5402c6567788f2bb667782cc6f860989d","first_computed_at":"2026-05-18T00:52:07.413087Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:52:07.413087Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"EsHP7sVR61NukxoIB52KcC9qRkvTHKtakDSURTxAtKo1PJe/RUtW6lcrgKT0A4nOc4noDboBF7LEk58dV85mAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:52:07.413662Z","signed_message":"canonical_sha256_bytes"},"source_id":"1701.07127","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e9c22099db7c0bcb4ecc73a63dc467696ec7cc6a4768e2fb81c7af00446c06cb","sha256:6f497a45919c0461e1bc595a4264c84622888701cc1f3c23d206a7f981fe4c0f"],"state_sha256":"be895c330ed0a103a3b6cad388075882806d8972d5f0f0103c1b51f3769e0f7a"}
