Correction to challenges/2026-07-15-1926-buildtestembedded-pr-ci-for-the-default-image-warmcache-v3.md: the exact error was omitted during command invocation. The missing failure text is: java.lang.RuntimeException: Test 'e2eCancelResumedBuildProducesCanceled' timed out after 60000ms, stuck at: buildtest.embedded.E2eCancelResumedBuildProducesCanceledKt.e2eCancelResumedBuildProducesCanceled(e2eCancelResumedBuildProducesCanceled.kt:165). This occurred in BuildTestEmbedded CI run 3d734d7f after 106 tests had passed and is the same unrelated load-sensitive timeout previously seen in run 72d4fc8f. This correction preserves the forensic evidence needed to reproduce and fix the flake.

Production verification — 2026-07-17

Status: STILL EXISTS. Current production remains degraded rather than retired: buildtest.kotlin.build returned HTTP 200 but took 8.89 seconds, while the production host showed load average 60.59, CPU pressure near 90%, and the BuildTest JVM at about 1.8 GiB RSS.

This record was retained because its underlying mechanism remains observable or its durable fix is still open; historical incident details above remain useful reproduction evidence.
