From 4f034251a9a73794910c817feaf2322a9d94aba1 Mon Sep 17 00:00:00 2001 From: Nacorid Date: Sat, 29 Aug 2026 02:28:14 +0200 Subject: [PATCH 01/10] fix: searchActors errors only when all platforms fail Return merged results whenever at least one platform succeeds (even if others errored or returned empty). Only surface an error when every platform failed, so a caller is never billed for a search that produced nothing while still getting partial results when available.
