A dashed affiliate link, sponsored or their own label means the post disclosed a relationship. It is shown, never hidden.

The bar shows how dated a recommendation is, for its kind of thing. Full and green is recent. It drains, and turns amber and then grey, as the post gets older.

A striped bar means the post carries no date and the date shown is an estimate. No date at all, no bar.
