We introduce Markovian Circuit Tracing (MCT), a diagnostic pipeline for testing whether transformer activations contain coarse state-transition structure. The benchmark uses synthetic Hidden Markov Model (HMM) tasks where latent states, transition matrices, Bayesian belief vectors, Bayes-optimal predictions, and forced-state counterfactual targets are known exactly. Across six HMM families and three seeds per family, tiny causal transformers learn near-Bayes next-token predictors","authors_text":"Abdullah X","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2026-05-20T07:19:21Z","title":"Markovian Circuit Tracing for Transformer State Dynamic"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.20824","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:b8fa69422072ad673f1f544d6493c4fbb603c54088a07d954c501417b90026b4","target":"record","created_at":"2026-05-21T01:04:56Z","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":"4e140a303e2e962ca8dd10eb039fea73687633969a4d45758dd184db9a0fc751","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2026-05-20T07:19:21Z","title_canon_sha256":"eb23d0ad7eaac7040a56ab111e866d490579722e3e50e7d4c1ba2f442f31450c"},"schema_version":"1.0","source":{"id":"2605.20824","kind":"arxiv","version":1}},"canonical_sha256":"b555f2635010adf5a520a96b5ae1560070b7cfd8f4d50f60e5628c9d54ca1ad9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b555f2635010adf5a520a96b5ae1560070b7cfd8f4d50f60e5628c9d54ca1ad9","first_computed_at":"2026-05-21T01:04:56.381218Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-21T01:04:56.381218Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+W0ynIM652WokFJ8c3k9v8HtJrKBAihgJveAKRFOMqFmJmc/6HT7mz4AcmDYgqTCuf7J69I0ahjJb51Rs6PCCQ==","signature_status":"signed_v1","signed_at":"2026-05-21T01:04:56.382068Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.20824","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b8fa69422072ad673f1f544d6493c4fbb603c54088a07d954c501417b90026b4","sha256:4e579f7a31e6bb1bdbaf4784b111226bab7c482f735db1df98acf118de815e1d"],"state_sha256":"f1da83e929e57fc946945f5fe4a646c4fb731b8ca42d407243fca4ba66009543"}
