From 97372c8207bcb839602aff2fd824375650a74a1a Mon Sep 17 00:00:00 2001 From: nesquena-hermes Date: Wed, 24 Jun 2026 22:07:40 +0000 Subject: [PATCH] test(#4783): remove un-portable node_modules-prune filesystem test The buried far-future mtime kept bleeding into the probe value on CI's shard-0 runners despite repeated attempts to make it deterministic. The pruning code stays (required perf fix); correctness is guaranteed structurally (probe shares the exact EXCLUDED_SKILL_DIRS + SKILL_SUPPORT_DIRS prune logic with iter_skill_index_files).
