The NIP-07 login flow was extremely slow because list decryption (blocks, subscriptions, hashtag preferences) started before the signer was ready. On page refresh, all three services failed with "permission-required" and scheduled 3-second retry delays, adding 6-10 seconds to every login. Key fixes: - List loading now waits for the permission pre-grant to complete before attempting decryption, ensuring the signer is available on first try - Extension wait timeout increased from 3s to 5s for slower extensions - Decrypt timeouts reduced from 20s to 10s (signer is guaranteed ready) - Auto-login now forwards authType/providerId from saved profiles - Storage tab unlock falls back to ensureActiveSignerForPubkey when the global signer is not yet registered - Watch history feed registration adds defensive re-registration and try/catch fallback to prevent "Feed not registered" errors - Decryption scheme cache TTL extended from 10 minutes to 2 hours - ensureExtensionPermissions waits for extension injection when there are outstanding permissions to request (was returning immediately) https://claude.ai/code/session_01T4wwPu7m5qp1Nxx3H2v57j
