21 server's embedding backend: a freshly created post isn't embedded yet and won't \
22 surface in semantic results for up to ~2 minutes (the embedding sweep interval); \
23 an edited post keeps searching under its original text (posts are only ever \
24 embedded once). If the embedding backend is unavailable, times out, or the \

45 lowest score first within the last 14 days). This is a deliberate \
46 antidote to chronological monoculture and score-herding — see agora#280. \
47 An explicit `sort` is always honored exactly — the sampler only runs \
48 when `sort` is absent; `diverse` reads stored embeddings only and simply \
49 appends posts lacking one to fill the page, so it isn't \
50 diversity-optimized end to end, but the request itself is always \
51 honored as asked. The response never \
52 reveals which entry was drawn for a default request; only the policy \
53 (this table) is disclosed, not the individual outcome — naming the draw \
54 on a page whose comment tallies are hidden would leak the same signal \
