We refer to this tendency to be overly lenient or overly critical as verifier strictness. In this work, we study whether verifier strictness can be controlled through hidden-state intervention. We uncover a verification-specific hidden-state signal: in step-wise verification, a verifier's tendency to accept or reject a solution step is encoded near the","authors_text":"Austin Xu, Jiang Gui, Shafiq Joty, Soroush Vosoughi, Yefan Zhou, Yilun Zhou","cross_cats":["cs.AI","cs.CL"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2026-05-20T05:48:16Z","title":"The Hidden Signal of Verifier Strictness: Controlling and Improving Step-Wise Verification via Selective Latent Steering"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.20745","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:eacabf78689b0354758d3cedc58b45e7ccd0095793f6af561e97dc0d63059a7b","target":"record","created_at":"2026-05-21T01:04:51Z","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":"26368b0b36027b5f190a385fc2e1bb62e440e52957defb663a162e766b148be2","cross_cats_sorted":["cs.AI","cs.CL"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2026-05-20T05:48:16Z","title_canon_sha256":"65c5afb14b897b6a137f1a935d84aebfbd1cb3fb629b7a4716b2d82f07a3d972"},"schema_version":"1.0","source":{"id":"2605.20745","kind":"arxiv","version":1}},"canonical_sha256":"3223fd1ff6ce22d99ae32cb29234c2962b02770473d5796408810cb50e527ce0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3223fd1ff6ce22d99ae32cb29234c2962b02770473d5796408810cb50e527ce0","first_computed_at":"2026-05-21T01:04:51.941922Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-21T01:04:51.941922Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DkmOq0/XUJhD2PtUvv4heDXAhQA7Px4Yu7uwDgXx95TjjSIEjX7ALHfcLpN2QNeIVUQAgWFAsIgNEknHfrxKCQ==","signature_status":"signed_v1","signed_at":"2026-05-21T01:04:51.942714Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.20745","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:eacabf78689b0354758d3cedc58b45e7ccd0095793f6af561e97dc0d63059a7b","sha256:5dddacfba330db2f0f5a301c470770a4e2d300bc4d92fb57e9af771f115688a5","sha256:1107ed8f5b41f55b2ca7e0b78d85080dbe73699ed7002e69f20e2ee44d35b92e"],"state_sha256":"eecc9b336a01f908f8b52dcd136e35aaf12df6842b596b0f9558e168a628cc71"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"fYoXDjdLz0BF0af48Hs1EozOkuN6OJZO0sZPh+NjXSnKed7y9Bx996ONFm3+bhVK5ITeRoRDprfJ3+zcsmsPCA==","signed_message":"bundle_sha256_bytes","signed_at":"2026-05-24T07:13:16.749082Z","bundle_sha256":"1cefd346cd7b8a30e4334b50fbed0edc3868f2f065bea74f2d38570635c24682"}}
