Repost deduplication filter
Multiple reposts of the same underlying post collapse to one candidate.
What it means for your posts
Ten mutuals reposting you ≠ ten timeline slots; it's one slot with better provenance.
A post removed by a filter is never scored at all for that viewer — no weight, however favorable, applies. This is why most “my reach died” experiences are filter stories, not weight stories. See the full filter pipeline and test a draft in the checker.
