   These are Windows FileSystemException flakes, in content_aware_hash_test.dart (not the same test in that file each time though). Error is consistent:

   FileSystemException: Deletion failed, path = '/b/s/w/ir/x/t/last_engine_commit_test.SDNXWC' (OS Error: Directory not empty, errno = 39)
     dart:io                                                               FileSystemEntity.deleteSync
     package:file/src/forwarding/forwarding_file_system_entity.dart 70:16  ForwardingFileSystemEntity.deleteSync
     test/last_engine_commit_test.dart 124:12                              main.<fn>

   I have hopefully fixed this with the recent merge of #195349, but we should confirm the flakiness drops before closing this issue.

   Closing this as fixed in #195349.

   • Test-level history (LUCI Analysis / ResultDB, presubmit + post-submit): dev/tools/test/last_engine_commit_test.dart (if there have been no engine changes, uses the first commit since the branch point) last failed on 2026-10-23 (build 8667190233172907601) and has passed 6,923 consecutive runs since. All 35 test cases across content_aware_hash_test.dart, last_engine_commit_test.dart, and update_engine_version_test.dart have 0 failures since PR Fix repo deletion test flake #195349 landed.
   • Builder post-submit history: Across 324 post-submit builds of Linux framework_tests_misc since build 30790 (through 31113), there have been 0 dev/tools failures, and the last 174 consecutive builds are green (0.00% flaky rate over the 100-commit window).
