Esbabbler link unfurl

Rich embeds (title, type icon, preview) when a published resource URL is posted in an esbabbler message.

Why deferred

Plain URLs to /view/[type]/[id] pages already work; unfurling is polish that touches the message pipeline (metadata fetch, embed rendering, cache) for cosmetic gain.

Revisit when

Shared published links are actually circulating in rooms.

Cheaper interim

Plain URL + the page's own OG meta tags (browsers/other platforms unfurl those for free).

Email sending

Deferred — actually delivering email-editor output (survey invites, personalized campaigns) to recipients.

Global calendar

Deferred — a calendar aggregating todos across all of a user's TodoList resources.
