Protocol support

Advertised NIPs

The relay advertises NIPs 1, 2, 9, 11, 17, 22, 28, 40, 42, 70, 71, 77 in its default configuration. "Covered" below means a relevant automated integration test exists and passed at the reviewed revision; it does not imply exhaustive conformance to every requirement in that NIP.

NIP	Implemented behavior observed	Evidence and qualification
01	Signed event publication; `OK`; `REQ`; `EVENT`; `EOSE`; `CLOSE`; live matching; common filters	Covered. ID and author filters use exact equality; prefix-filter behavior is not implemented. Stored tags lose fields after the first value.
02	Kind 3 contact lists use replaceable-event behavior	Covered for replacement of an older list.
09	Kind 5 requests delete same-author targets addressed by `e` or `a`; deletion request remains stored	Covered. No tombstone prevents later re-publication.
11	HTTP relay information document with CORS headers and configurable metadata	Covered. Limit values are advertised but not enforced.
17	Kind 10050 storage and authenticated access control for kind 1059 gift wraps	Covered for recipient access and unauthenticated denial.
22	Kind 1111 comments and upper/lower-case indexed tag filtering	Covered for storing and finding a comment by `E` and `e`.
28	Kinds 40–44; latest kind 41 retained per referenced channel	Covered. Moderation events are stored but not enforced.
40	Expiration stored; expired records omitted from queries; already-expired events rejected	Covered. Expired rows are hidden rather than purged.
42	Challenge on connection and signed kind 22242 authentication	Covered with NIP-70. Relay URL value and authentication-event time are not validated.
70	`-`-tagged events require authentication as the event author	Covered for unauthenticated, matching-author, and different-author publication.
71	Kinds 21 and 34235 can be stored and queried; addressable replacement rules apply to kind 34235	Covered for normal and addressable video events.
77	`NEG-OPEN`, `NEG-MSG`, `NEG-CLOSE`, `NEG-ERR`; reconciliation over timestamp/ID vectors	Covered for a client missing two of five events. Sessions are connection-local.

General event semantics

Kinds 0, 3, and 10000–19999 are treated as replaceable by author and kind.
Kinds 30000–39999 are treated as parameterized replaceable by author, kind, and d tag.
Kind 41 receives special replacement behavior keyed by its e tag.
Only tags with a one-character alphabetic name are indexed. Only the tag name and first value are stored.
Query results exclude expired records and are ordered by newest timestamp then ID, unless requested for Negentropy.

Conformance work still needed

Test the complete NIP-01 message grammar, malformed input, filter prefixes, limits, duplicate events, and concurrent subscription behavior.
Preserve every tag field exactly through a storage round trip.
Validate NIP-42 relay URLs and freshness.
Decide and document gift-wrap read/write, retention, and operator-access policy.
Run a compatibility suite against the Nostr clients and SDKs the product line intends to support.
