We propose a streaming, source-free test-time adaptation (TTA) recipe that combines entropy minimization (Tent) with Batch-Norm statistic refresh and two safety rails: an entropy gate to pause adaptation on uncertain windows and an EMA-based reset to reel back drift. On Sleep-EDF Expanded, using single-lead EEG (Fpz-Cz, 100 Hz, 30s epochs; R&K to AASM mapping), we show consistent gains over a frozen baseline at seconds-level latency and minimal memory, reporting per-stage metrics and Co","authors_text":"Faisal R Jahangiri, Hritik Arasu","cross_cats":["cs.AI","cs.NE","q-bio.NC"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2025-09-03T03:42:31Z","title":"StableSleep: Source-Free Test-Time Adaptation for Sleep Staging with Lightweight Safety Rails"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2509.02982","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":"sha256:48a0c12d29c38cacd0fd5c4efbe520b35005ad168085dc2952aee260289defde","target":"record","created_at":"2026-07-05T12:04:01Z","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":"24594f34ad6f90114fe2758b512fa9b9b5bbeb7651c3aae342fa7c2a7bb287d8","cross_cats_sorted":["cs.AI","cs.NE","q-bio.NC"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2025-09-03T03:42:31Z","title_canon_sha256":"ac955a33259db1a24d6ac5b83c019c7d5c941610b16eb6e889cb45b2b1a8dd96"},"schema_version":"1.0","source":{"id":"2509.02982","kind":"arxiv","version":1}},"canonical_sha256":"8a011742b56ef13f0732d2b68363ef8222bb23af93b462fd0ee7dcc7bbc3dfdb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8a011742b56ef13f0732d2b68363ef8222bb23af93b462fd0ee7dcc7bbc3dfdb","first_computed_at":"2026-07-05T12:04:01.087331Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T12:04:01.087331Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rk7VhGWseMVkcvT7x28qNcoas6BpVI3a4aPf6Ie4ldI8r/rv+AhcnPZ6tbsbGEG/PmboaIokcsTWEu0IvIosCA==","signature_status":"signed_v1","signed_at":"2026-07-05T12:04:01.087883Z","signed_message":"canonical_sha256_bytes"},"source_id":"2509.02982","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:48a0c12d29c38cacd0fd5c4efbe520b35005ad168085dc2952aee260289defde","sha256:47189337ad1448cbd5ed8c62962d33b727bfaa199c36ef961c443e3ba7f41cfc"],"state_sha256":"92d933dd71c2ee45d08d1180212cb6ad6c4609095f45f2fb34c4d817fdc8e41c"}
