Arnas Donauskas 62073d9915 feat(flows): add send_media node for image / video / document sends ... Lets flows attach an image, video, or document (e.g. PDF invoice / receipt) to a customer message — the most-requested gap in v1 was that nodes were text-only. Single node with a `media_type` discriminator rather than three node types: Meta's wire payload differs only in the top-level key, so three types would triple the surface area (forms, engine cases, menu entries) for no behavioural difference. Files are uploaded directly from the builder to a new public `flow-media` Supabase Storage bucket (per-user RLS, 16 MB cap, MIME allowlist) and the resulting public URL is what Meta fetches at send time. Same trade-off as the existing avatars bucket. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>		2026-05-29 19:11:29 +02:00
