bvandeusenandClaude Opus 5.5	7cc34b5724	fix: a Discord message that re-posts a file is grouped, and joins the drop it repeats ... Grouping read a message's images through primary_post_id alone, which only the first message imported with a file holds. The backfill runs newest-first, so the original message usually owned nothing: 101 of Yellowroom's messages (mostly 2018-2020) could never be grouped. Every image they carried also sat in another message (296 links, measured on the live instance). _message_images unions ownership with provenance for the candidate query, the drop seed, the member image links, and the merge pass. Nothing is re-owned. A later drop carrying the very file an earlier one carries now merges by a new same_image route, which nearest-neighbour could not see because it skips the image itself.

bvandeusenandClaude Opus 5.5	e08401c44a	feat: a creator's trickle becomes one drop instead of a card per message (4390) ... The operator, on a feed of "Grouped from 1 Discord message" cards: "the groups are still single image even when they can clearly be seen as group". 665 of Yellowroom's 714 drops were one message. Both join paths demand cosine <= 0.10 to a drop's FIRST image. The stages of one piece fail that: each is nearest the one before, not the first. `svtt_wip4` never joined `svtt_wip3` from the day before. Measured on artist 8 before writing it: - phash cannot see it. Stages sit 68-134 bits apart; unrelated same-artist pairs have a median of 126 and a p5 of 110 (lesson #4400). - The embedding's nearest neighbour can. Every stage of three real trickles had a sibling as its single nearest image in the artist's library. In a control over all 137 recent Discord images, a nearest neighbour that was another message within 7 days carried the same working name 53 times out of 53. Mismatches start past 7 days. A new merge pass runs last in the sweep. A later drop folds into an earlier one within discord_group_close_after_hours (168h, the measured 7 days) when they share a gated leading working name, or when one's image is the other's nearest neighbour. A drop reaching several earlier drops pulls them all together, unless two of them are named as different pieces. A merge carries teaser links across (the payload FK would otherwise cascade them away). Growth is stamped at the messages' own time, so merging history never jumps an old drop to the top of the feed. Each drop records the route it merged by, and is checked once. Offline replay over Yellowroom's 127 drops since 2025: they become 70 posts. The Marin trickle ("Very early Marin" -> 3 screenshots -> MarinaraSauce_base) becomes one post of 5 by nearest neighbour. svtt, 0-k1, cnni14 and 0adm come together by name. FAMILY_MAX_POSTS moves to post_naming, so the grouper and the teaser card share one definition.
