+- Hosted domain: `https://blog.3031023.xyz` is attached only to

+- Shared deployment-boundary update: successful Gitea runs 133 (blog) and 134
+  (primary) rebuilt the two Workers independently from the same commit.
+- Blog-only content update: commit `4e2d0f8` changed only
+  `sites/blog/site.json`; successful Gitea run 135 deployed only the blog
+  Worker. No primary deployment was created for that commit.
+- Rollback remains independent: Cloudflare maintains distinct deployment
+  histories for `3031023-xyz-www` and `3031023-xyz-blog-preview`. No live
+  rollback was executed because there was no incident; the primary rollback
+  procedure is documented in `cutover-runbook.md`.

+# Phase 5 verification — independent hosted subdomain
+
+## Hosted Workers
+
+| Hostname | Static Worker | Role |
+| --- | --- | --- |
+| `3031023.xyz` | `3031023-xyz-www` | Primary production site |
+| `blog.3031023.xyz` | `3031023-xyz-blog-preview` | Independently hosted pilot subdomain |
+
+Neither hosted site uses a hostname-routing Worker. Each has its own static
+assets deployment and Cloudflare deployment history.
+
+## Deployment boundary evidence
+
+| Evidence | Result |
+| --- | --- |
+| Runs 133 and 134 | Shared deployment-workflow change produced one successful blog deployment and one successful primary deployment. |
+| Commit `4e2d0f8`, run 135 | A change limited to `sites/blog/site.json` produced one successful blog deployment and no primary deployment. |
+| Public checks | Blog returned 200 with the expected title; its unknown route returned 404. |
+
+## Operating notes
+
+The blog is intentionally using the pilot preview build, so its page metadata
+and generated robots rules are non-indexable until a separately approved blog
+production release is created. Markdown content collections, CMS integration,
+and client editing are not part of this phase.
+
+Rollback one site by selecting a prior deployment in that Worker’s individual
+Cloudflare deployment history. Do not alter the other Worker or either site’s
+domain binding during that operation.
