Atomic daily publication.
Every section must pass before publication. Missing sources never become a partial dashboard.
Source-faithful labels.
Formal chart ranks, source order, geographic scope, null values, and source dates are kept distinct.
Exact overlap only.
Cross-platform overlap uses normalized exact text equality. It does not infer semantic similarity or manufacture topics.
Daily replacement.
This route reads only the current UTC edition from MongoDB. If it is absent, the page says so instead of serving an older result.
