+- 2026-10-13 Cloudflare's GraphQL Analytics API (`httpRequestsAdaptiveGroups`, zone `skilld.dev`) counted 2,219 verified Googlebot requests from 2026-10-06 to 2026-10-12 UTC, about 317 a day.

+  All 172 verified 403 responses were OG image URLs under `/_og/d/…png`, refused by nuxt-og-image's signature check in the Worker.
+  127 had no signature, and 45 had a signature that no longer verifies. The og:image URLs of the home page and 2 Skill pages returned 200.
+  This read does not split discovery from refresh. The query and its baseline table are in Weekly measurement step 2.
+  gscdump.com `docs/work/EXECUTE-bing-search-data-expansion.md` dates the Bing fix: a fixed-IP relay, [#628](https://github.com/harlan-zw/gscdump.com/pull/628), shipped on 2026-10-01 at 17:35 UTC.

 - 2026-10-11 readiness read with NuxtSEO CLI 0.5.8 matched all 41 watches, with no missing or empty Checkpoint lists.
   No Checkpoint changed from the earlier 10 October read. Latest Checkpoints span 4 to 8 October UTC.
   This is readiness evidence, not the first weekly measurement.

 - Scale rule: if Bing indexes the curated pages and Google does not, the content can be indexed. The problem is Google's verdict on the domain.
