Choosing the right checkpoint from a world-model training run is difficult: validation loss and multi-step prediction RMSE keep improving long after closed-loop performance has collapsed. We present a suite of structural validation-time diagnostics drawn from optimal-control theory and apply them to Gymnasium's LunarLander v3, which features shaped rewards. We train an RSSM [5, 4] world model on it and treat per checkpoint CEM-MPC return as the oracle for close","authors_text":"Nikolai Smolyanskiy","cross_cats":["cs.AI","cs.SY","eess.SY"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2026-07-02T05:46:03Z","title":"Predicting Closed-Loop Performance of Latent World Models: Offline Checkpoint Selection for MPC and Model-Based RL Under Non-Markovian Rewards in LunarLander"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.01736","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":"sha256:1c4251ea7361106e71c002412a427550d990dfa4e30a5ec8402878106e6c4542","target":"record","created_at":"2026-07-03T01:17:28Z","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":"7fcd316d4035b444b4417a4c6708dda55257e1354c632aba0cf66490bfc4f1e3","cross_cats_sorted":["cs.AI","cs.SY","eess.SY"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2026-07-02T05:46:03Z","title_canon_sha256":"2a08e15f3a65b406c19d59e547cd272bc7eebd36ad28ca357dba0cc0e16f7957"},"schema_version":"1.0","source":{"id":"2607.01736","kind":"arxiv","version":1}},"canonical_sha256":"2af1b80a68463f93244980f85be1615e439357423bb80b5ef4036df7c78e7f3b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2af1b80a68463f93244980f85be1615e439357423bb80b5ef4036df7c78e7f3b","first_computed_at":"2026-07-03T01:17:28.155001Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-03T01:17:28.155001Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6e6ZopzQlHPuh0VPKN0uFOhbgmZ4vCfvOfVrEKawhsj/0xBJvFBsmJi+vR9ilB4El5axYWsnqlg7dc3fue17Bg==","signature_status":"signed_v1","signed_at":"2026-07-03T01:17:28.155425Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.01736","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1c4251ea7361106e71c002412a427550d990dfa4e30a5ec8402878106e6c4542","sha256:2ef5f6f70a7d473dab51693473de1dddd696a7f89157b90471ef99be14546b2a"],"state_sha256":"aad0bec31ec89e7e18a072dd188bcfb678536b41ac0c5af5825bc1c68d6ae491"}
