Existing world-action models often rely on large generative world models or dense future rollouts, which are expensive and spend capacity on visual details weakly coupled to control. We present Bridge-WA, a lightweight world-action framework that distills a frozen future-change teacher into three compact priors: future tokens for intended outcomes, change maps for intervention support, and motion-flow maps for local transi","authors_text":"Hanting Wang, Liang Lin, Mingtong Dai, Qijun Zhong, Yang Liu, Yongjie Bai","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2026-07-02T14:03:44Z","title":"Bridge-WA: Predicting Where and How the World Changes for Robotic Action"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.02195","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":"sha256:5b400c262e2435b3c868d39701ceab2f6ba4ae2ccb830726f31b80648afc2a5c","target":"record","created_at":"2026-07-03T01:17:44Z","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":"3d3fd1d4b7f9178de5bd74c88c4d774e6f5242af501091102bff140beaa6b120","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2026-07-02T14:03:44Z","title_canon_sha256":"a01219254740cb07d50100f06e6954fc8657363bd1dd88a5a2f18d4333e45742"},"schema_version":"1.0","source":{"id":"2607.02195","kind":"arxiv","version":1}},"canonical_sha256":"566d648c864a82ff404ef7542e0d1d338e1a51b496176b2b6528731ac2e5ec58","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"566d648c864a82ff404ef7542e0d1d338e1a51b496176b2b6528731ac2e5ec58","first_computed_at":"2026-07-03T01:17:44.694376Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-03T01:17:44.694376Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ml1DwLzoix973Ck8z9b9p60TRrKfW70fmmWEQl/wMjX4veWU8U5gbqtGtUAy8UFE/3d+zGdlKQfGo4RvFQy6BA==","signature_status":"signed_v1","signed_at":"2026-07-03T01:17:44.694754Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.02195","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5b400c262e2435b3c868d39701ceab2f6ba4ae2ccb830726f31b80648afc2a5c","sha256:9d3a2c6742f60f09d52394cd1bfd367dc117fd727681289316e5ed34992bd539"],"state_sha256":"5dd248bde1c34b5a0d412330becb4d38284d437f6f66424de6edbb7a53fea659"}
