Approved events are mirrored to Nostr as NIP-52 calendar events (kind
31922) signed by the wallet owner's pubkey, and incoming kind 31922/31923
events from subscribed relays are synced into the local DB so events
created on other LNbits instances or Nostr clients show up locally.
- m009 stores nostr_event_id + nostr_event_created_at on each event
(used for replaceable updates and NIP-09 deletes); m011 adds location
+ JSON-encoded categories list (NIP-52 location/`t` tags).
- models: Event/PublicEvent/CreateEvent gain location, categories,
nostr_event_id, nostr_event_created_at; parse_categories validator
decodes the JSON column on read.
- nostr/{event,nostr_client}.py: Schnorr signing, websocket relay client,
and a NostrEvent model (publish-only and subscribe variants).
- nostr_publisher.py: build/sign NIP-52 kind 31922 events and NIP-09
delete events; publish via the relay client.
- nostr_sync.py: subscribe to kinds 31922/31923, dedupe by nostr_event_id
/ d-tag, upsert Events; auto-approves discovered Nostr events since
they're already public.
- nostr_hooks.py: thin bridge that views_api handlers call to publish
or delete a NIP-52 event for a given local event. Lives in its own
module to keep `from . import nostr_client` out of the view layer
and avoid the views_api -> publisher import cycle.
- views_api: hooks publish_or_delete_nostr_event into create-on-approved,
update-when-already-published, cancel (delete), delete (delete), and
approve (publish).
- __init__.py: 3-task lifespan — wait_for_paid_invoices (upstream),
NostrClient bootstrap, and the NIP-52 sync loop. Module-level
nostr_client global is set by the bootstrap and read dynamically by
publish_or_delete_nostr_event so the import order works regardless of
whether nostrclient is up at startup.
