Age ceiling filter
Removes posts older than a max age (value withheld as a param). The Phoenix ranker itself buckets post age in 60-minute buckets capped at 4800 minutes = 80 hours (phoenix/recsys_model.py POST_AGE_MAX_MINUTES) — beyond that, age is indistinguishable.
What it means for your posts
Your post's earning window is short. 'Evergreen recycling' exists because the pipeline hard-expires candidates.
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.
