From d7fb86f0a063b30fd1ea5b8c44dc564ebd1a3fa6 Mon Sep 17 00:00:00 2001 From: clawbot Date: Thu, 3 Sep 2026 21:06:42 +0000 Subject: [PATCH] Document the Go test-result cache as a second, independent cache Go's test-result cache sits below the Docker layer cache that issue #26 addresses. CHECK_EPOCH forces the RUN make test step to re-execute, but GOCACHE baked into earlier image layers survives into the re-executed step, so go test can still do no work. Record that these are two separate defects so a fix for one is not recorded as covering the other. Also correct the TODO.md Completed Steps date to the landing date, which matches the REPO_POLICIES.md last_modified front matter.
