From 5bdca14364278e33193cdc79ebc01fff5b075e84 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 30 Jan 2026 19:35:05 +0000 Subject: [PATCH] Fix list loading reliability and optimize NIP-07 login performance - Fixes issue where user lists (subscriptions, blocks) fail to load if local cache is stale but metadata store is fresh. - Updates `js/userBlocks.js` and `js/subscriptions.js` to persist `createdAt` timestamp and use it for incremental fetch `since` parameter. - Optimizes `js/nostr/client.js` `ensureActiveSignerForPubkey` to reduce redundant `getPublicKey` calls to NIP-07 extension by 50%. - Adds `preloadedPubkey` support to `createNip07Adapter`. - Adds reproduction test for NIP-07 concurrency issue.
