hreflang.cluster-incomplete
Every locale the sitemap publishes must appear in the route's hreflang cluster
Why it matters
Listing a URL in your sitemap is you saying that version exists and should be indexed. Leaving it out of the hreflang cluster then puts it outside the group it belongs to, so it competes with its own translations instead of consolidating with them — which is the one thing hreflang exists to prevent. Google requires every version to list every other, and the sitemap is your own evidence that the missing one is real.
What the finding looks like
The message goflag prints, with example values substituted.
How to fix it
The catalogue carries no snippet for a site rule: a cross-page rule builds its remedy from what the crawl found, so goflag attaches the fix to the finding itself rather than to the rule. Run it and read the finding.
Says who?
This rule is vendor-spec, and it cites the document below. Nothing here is goflag’s opinion of what a good page looks like — if you disagree with a finding, this is what you are disagreeing with.
