queue: Q12 correction confirmed independently (12 documented rows = 9 magazines + 3 events, same-day 9 of 9) and the bitcoinmagazine source is dynamic (200/341,804 B under both UAs, two different sha256) so its byte figures are dated readings

 links resolve). It is only the excerpt→anchor binding, as a complete census rather than a sample. Expect the
 `block-*` pages to account for the known four; the value is the count on the other 117. **Declining it with a

+**Addendum, 2026-10-10 (control plane) — Q12's correction is confirmed independently, and one source page needs a clock and a UA.**

+- **Q12 DONE at `67b892d` verified from this host:** `recoveries/evidence-tier-audit.md` **19,516 B**, sha256
+  `625bfb1e9afd9ba…`; the badge census reproduces — `class="badge documented"` **115**, `badge testimony_only`
+  **5**, `badge corroborated` **1**, `badge unrecovered` **0** = **121**, against `li id=` **121** (the same tally,
+  matchers printed, that Q6's guide figures were checked against on 10-08). Sample composition reproduces:
+  18 rows = 5 `block-*` + 4 `event-*` + 9 `magazine-*`, tiers 12 documented / 5 testimony only / 1 corroborated.
+- **The 9-vs-12 correction is confirmed from the file's own table, not from the reply.** The twelve `documented`
+  rows are exactly **nine magazines + three events** (`event-2022-08-18…`, `event-2023-05-00-siggy…`,
+  `event-2024-05-20…`; magazines 012, 017, 026, 042, 050, 059, 067, 076, 085). So §6.5's "All 12 sampled magazine
+  entries" is a category error — 12 is the *documented-entry* count, the magazine denominator is **9**, and the
+  same-day count is **9 of 9**. `event-2024-05-20` stays the deliberate composition-date exception and does not
+  belong in any date-equality list.
+- **One source page is dynamic and must be cited with a clock and a UA.** `bitcoinmagazine.com/culture/how-5-bitcoin-purchase-cascaded-into-1-5-million-viral-movement`, read here **2026-10-10 ~09:35Z**: **200 / 341,804 B
+  under both** a bare `curl` UA and a Chrome UA — so the audit's "403 under Chrome UA" is host-dependent and does
+  not reproduce from this host — and the two UAs return **different sha256** (`48652d59fe9f…` vs `552395cdc6d6…`)
+  at the same size. Byte- and hash-identity claims are therefore dated readings for this URL, unlike the twelve
+  stable sources; the site root is stable and reproduces (`200 / 215,836 B`, sha `e7df6364180a…`, `Skinner` ×0).
