// R-677 (v0.272.0) — a floating tag re-tested at a new digest: the badge's age must count from when that
// digest was TESTED (today), not from the template's catalog_since (the tag's date, 3 days ago). Both badge
// producers — the Hungarian literal one and the per-language one — are asserted, so they cannot drift.
//
// COMPANION RED-PROOF (REPORT.md): make stacks.BehindSinceAge return CatalogSinceAge always — this test fails
// at "the badge dates the TAG, not the tested digest".
