Aggregates every followed (non-muted) signer's latest public saved list into three readings. Empty when nobody you follow has published, or when you haven't followed anyone yet.
Nothing overlaps yet. Co-saved means two or more followed signers independently saved the same block.
Nobody's published a fresh saved list this week. Signal is based on event created_at — bulk historical lists don't count as "new."
No saves tallied yet.
Opt in to a weekly HTML email of this recap. The sidecar
worker isn't live yet — your subscription intent is stored
locally in sparrow:digest-subscription and sent
when /api/sparrow/digest-subscribe comes up. Worker
will never hold secret material: only signed-payload pointers
(relays + npub + preferences).
Schema documented at /sparrow.json under
nostr.federated_lists.digest_sidecar. Unsubscribe is a
local clear + future worker DELETE.
