in_network_ids is passed to the VF client without deduplication, while oon_ids is deduped four lines below. retweeted_tweet_id is pushed for every candidate that has one, so the same ID repeats once per retweet of a given post — most often when that post is going viral. Neither VfClient implementation dedupes its input: StratoVfClient builds one call per element, and XaiVfClient chunks by XAI_VF_MAX_BATCH_SIZE, so duplicates consume batch slots and can force an extra round trip. Not a correctness issue — results collapse into a HashMap keyed by tweet ID — but redundant work on the For You serving path. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Deduplicate in_network_ids before VF lookup
…or_id. run_hydrators hydrates every hydrator from one snapshot, then applies writes in vec order. Reordering CoreData before InNetwork does not change what hydrate sees. Stamp in_network from the live author_id on write-back. Co-authored-by: Jon Bailey <Pitchfork-and-Torch@users.noreply.github.com>

Bug
run_hydratorsjoin_alls every hydrator against the source snapshot, then applies writes in vec order. InNetwork.hydrate reads TweetMixerauthor_id = 0and stampsin_network = Some(false). CoreData.update then fills the TES author. Copying the snapshot stamp keeps OON.xai-org#128 only reorders the vec. That does not change what hydrate sees. VF then fetches at TimelineHomeRecommendations. Recs-only Drop fires (DO_NOT_AMPLIFY, NSFW_HIGH_RECALL, SPAM_HIGH_RECALL, MALICIOUS_URL). The same followee on Home is Allow.
