Aggregates everything held about an Owner (gdpr-export.ts: pets, posts,
stories, comments, reactions, reposts, follows/blocks, health records,
messages, notifications, reports, ban/consent history, Clerk profile)
into a single JSON bundle, uploads it to a private Supabase Storage
bucket (data-export-storage.ts — separate from the public pet-avatars
bucket used for media), and emails the owner a 7-day signed download
link via the new SMTP module. Triggered from a new export button per
user in /p/[secret]/users, logged to ModerationLog.
Deliberately not a zip with embedded media bytes: avoids new archiving
dependencies, the risk of a slow synchronous request for owners with
many posts, and the fact that Mux video assets aren't trivially
re-downloadable — media is referenced by its existing CDN URL instead.
Ad interactions and issued invite codes are not yet included, flagged
in the export's own scope note rather than silently omitted.
Verified end-to-end against the live shared DB before committing:
built a real export, uploaded it, generated a signed URL, and sent a
real test email — all succeeded.
