Trust & safety visibility (VF) filter
Applies trust-and-safety visibility verdicts AFTER ranking. The enforcement logic lives in a withheld crate (xai_visibility_filtering) — this is where actual 'shadowbans' would live, and it is NOT public.
What it means for your posts
Honesty note: nobody outside X can tell you your VF status from the open code. Tools claiming to 'detect shadowbans' from this repo are guessing.
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.
