From 9c618f9ba1bd1859bacf2ec0592df30a2aeba19e Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 1 Jul 2026 14:48:40 +0000 Subject: [PATCH] fix(quartz): don't drop outgoing events on NIP-42 auth-required NAKs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PoolEventOutboxState treated an `auth-required` OK-false the same as any transient failure, recording it against the per-relay Tries budget (responses > 2 drops the event on the next send attempt). Relays that NAK every unauthenticated EVENT could therefore exhaust the budget and drop the message before the AUTH handshake completed — the event was gone by the time syncFilters re-sent it after the auth OK. Treat `auth-required` as a deferred state instead: keep the relay in relaysRemaining and record no failure, so the existing syncFilters-after-auth path redelivers it. Mirrors the behavior already present in StandaloneRelayClient. Terminal rejections (invalid/pow/ replaced/deleted) and ordinary transient errors are unchanged.
