+**Completed:** The source-only consumer publication fixture runs one meaningful
+compatibility check against its committed note and module, then confirms the
+annotated tag on a local Git remote. A separate binary consumer fixture builds
+`buildinfo` binaries for selected Linux targets, checks native version output,
+and delivers both binaries plus `SHA256SUMS` to a local HTTP Gitea fixture.
+PromptKit and Narratio were reviewed read-only on 2026-10-06; the product
+roadmap records retained settings, runtime and policy/procedure adaptations,
+and projected deletion ranges. No sibling repositories were changed.

+The final documentation review reconciled GoDoc, CLI/configuration references,
+consumer guidance, Woodpecker examples, the internal inventory, and product
+roadmap. The pre-release API migration is `Validate` to `AdditionalChecks` and
+`DeliveryRequest.Build` to `*BuildSpec`, with `Prebuilt` for retained artifacts;
+JSON `checks` remains the ordered additional-check setting. No new product
+decision was required. The completed stages address F1–F8; real source
+publication, an immutable tool pin, credentials, workflow activation, and live
+Gitea/Woodpecker verification remain deployment work.
+
+The full offline suite and API boundary check pass with Go 1.25.0. Go formatting,
+documentation whitespace, and changed local-link checks pass.
