nostr/event.py
Bare NIP-01 NostrEvent with canonical id computation.
nostr/nostr_client.py
Bidirectional WebSocket client (lifted from events ext, kept
local). Connects to nostrclient ext's internal relay endpoint,
dedups by event id (LRU 1000).
nostr_publisher.py
Builders for:
* kind 0 — restaurant profile (NIP-01 metadata)
* kind 30402 — menu item (NIP-99 classified listing,
parameterized replaceable by item.id)
* kind 5 — deletion request (NIP-09)
Schnorr signing via coincurve (BIP-340).
Menu listings carry structured price tags (["price", n, currency]),
status (active|sold) so customers see sold-out items, and 't' tags
for category, dietary, allergens (allergen:<x>) and ingredients
(ingr:<x>) so webapps can filter without parsing markdown.
Restaurants can sign with their own keypair (per-restaurant Nostr
identity) or fall back to the LNbits Account keypair.
nostr_sync.py
Subscribes to:
* kind 30402 #t=menu — backfill 200 + live (echo confirmation
for now; foreign-menu indexing deferred until we settle on a
federated cache table).
* kind 1059 — NIP-17 gift-wrapped DMs, only when
settings.nostr_orders_enabled. Decryption stubbed (needs
NIP-44 v2 unwrap); REST stays the supported transport
until that's wired up. _place_order_from_dm is complete and
ready for the decryption hook.
