From d38585f376ff17c7c1b4a40c762526b4bb841a0f 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 18:47:08 +0000 Subject: [PATCH] Fix NIP-07 adapter race condition with lazy encryption capability injection - Modified `js/nostr/adapters/nip07Adapter.js` to use dynamic getters for `capabilities` (nip04/nip44) and unconditionally expose encryption methods. - Updated `js/nostr/client.js` to use `Object.getOwnPropertyDescriptor` when handling `signer.capabilities`. - Added `tests/nostr/nip07Adapter-race-condition.test.mjs` to verify the fix. - Fixed test environment issues in `tests/nostr/adapters.test.mjs` and `tests/nostr-login-permissions.test.mjs`.
