 - Do not mix action tags in one workflow update.
 - Do not assume a release workflow will run from a tag push in all environments; reusable workflow call paths are supported.
 - Do not treat `VOCIFERATE_REPOSITORY_URL` as a full repository URL; it must be a base URL.
-- Keep displayed URLs protocol-relative (`//`) when writing markdown/browser-facing outputs.
+- Always use explicit `https://` protocol in displayed URLs; never use protocol-relative `//` prefixes.
 - If a workflow environment does not support `GITHUB_STEP_SUMMARY`, append markdown to a file and print it in a final `Summary` step.

+- Browser-facing URLs emitted in generated changelog links, workflow summaries, and markdown now use explicit `https://` protocol.
 - Release workflows now collect summary markdown into portable temp files and print it in explicit `Summary` steps instead of relying on unsupported `GITHUB_STEP_SUMMARY` output.
 - Prepare now recreates the standard `Unreleased` section headers after promoting notes into a tagged release entry.
