Closes#997.
Send original files from any event as a token-protected download link, with an
optional client-upload channel. Strictly opt-in behind a new `transfers`
feature flag, default OFF.
Migrations 170-172 (transfers, transfer_files, transfer_extra_files,
transfer_uploads, transfer_recipients, transfer_downloads, default settings and
two email templates) — all hasTable/hasColumn-guarded and idempotent, with
destructive statements confined to down().
Backend: transferService (CRUD, 256-bit download token, 6-char upload token,
cross-event ZIP streaming of originals), admin CRUD routes, and two public
token routes. transferCleanupService runs an hourly retention sweep; source-event
photos are never touched. All three routers fail closed via
requireFeatureFlag('transfers').
Review closed two ownership blockers, both the same root cause — permissions
used where ownership was needed:
- photoIds arrived from the request body and were validated only for existence,
so a scoped admin could bundle any event's originals and hand them out through
the public download token. filterOwnedPhotoIds now resolves ids to their events
and gates them through filterOwnedEventIds, on both the create and add-files
paths.
- The transfer list was unscoped and carried each row's download token, so any
admin with events.view could read another's token and fetch their originals.
The list is now scoped by created_by, the token/url fields are stripped from
the list payload, and a single router.use('/:id', requireTransferOwnership)
covers all twelve /:id routes, 404ing foreign and missing alike.
The admin photo picker filters its event list to the same rule, so the UI stops
offering picks the API would discard.
Fork-PR workflows had not been approved since the fix commits, so the PR's green
checks were stale against the pre-fix head. Verified by dispatching tests.yml
against the actual head: backend and frontend both green.
Follow-up: neither ownership guard has a regression test yet.
