Authors: Meta
Version: Retrieved for the candidate pack on 2026-11-04 (SHA-256 977d071052e3f5dc267e1022671babf6a7967111f9bf2ad84e88b6419b405e61) directly from the publisher’s host. Retrieved again on 2026-11-03 with the same SHA-256. Meta's own address for the report answered HTTP 400 to the candidate pack, so the report was read on arXiv. The copy read prints 'Date: June 12, 2026'; arXiv's margin stamp on its first page reads 14 May 2026, the submission date.

Attribution: Meta, “Muse Spark Safety & Preparedness Report (arXiv 2606.12429v1)”.
Reuse: No open redistribution licence asserted. Bibliographic metadata, editorial paraphrases and short attributed quotations (at most 50 words each). Recheck terms before wider redistribution.
Check notes: Candidate pack passage, model cards compared (research/model-cards-2). The quotation (4 words) matched the card’s text retrieved for the candidate pack on 2026-11-04 (SHA-256 977d071052e3f5dc267e1022671babf6a7967111f9bf2ad84e88b6419b405e61) and again on 2026-11-04, after the adjudication, in a fresh retrieval with the same SHA-256. Matching ignored differences of whitespace, case, quotation marks, dashes, PDF line-break hyphens and Unicode compatibility forms, so the source’s typography can differ. No human editorial review.

Status and meaning

Editorial status. Machine-checked. Machines found this record and checked it against its sources; no person accepted it individually. Each evidence record above shows how it was checked.

Relation. Publication of a specific document or version. Publication of a policy is not evidence of implementation.

Date. The date printed on the expression read, which does not say what kind of date it is. An earlier expression, Meta's own copy printing April 14, 2026, is recorded as a further source of the report; no passage is quoted from it.
