Correction and full detail for https://github.com/CodexCoder21Organization/PlanRepository/blob/main/challenges/2026-07-14-0025-buildtest-rerun-fa90fc90-for-urlresolver-pr-https-github.md: shell quoting stripped two diagnostic phrases from that report. Buildtest rerun fa90fc90 for UrlResolver PR https://github.com/CodexCoder21Organization/UrlResolver/pull/773 became infrastructure-failing after prolonged Coursier and repository-network degradation. The executor stayed alive and test-events.jsonl advanced, but testMapReturnWithStringValue failed before execution with java.lang.RuntimeException: Failed to resolve unified test classpath after 3 attempts over 180320ms; every attempt ended java.net.SocketTimeoutException because the Coursier fetch exceeded kompile.coursier.fetchAttemptTimeoutMillis=60000ms. testE2eObservableInResultOverP2P likewise failed before execution because resolving workspace-local artifact foundation.url:resolver:0.0.632 exhausted 3 attempts over 180307ms. Hundreds of actual tests passed, including the relay sibling test observed in the XML aggregate, but the unrelated resolution failures will make the remote check fail after more than an hour; meanwhile the buildtest API repeatedly returned HTTP 503 although executor events remained fresh. Workaround: preserve the run until terminal for evidence, then rerequest the failed remote suite and use executor test-events.jsonl plus build.log as ground truth during frontend flaps. Durable fix: reuse the already-built workspace-local artifact and unified classpath across shards and tests, or classify exhausted repository fetches as retryable infrastructure failures and automatically reprovision or rerun the shard instead of attributing them to unrelated tests.
