Input

instructions: What kind of failure is this CI run? Use the log, the change (if there is one) and the CI facts (attempts on this commit, the history of the same test or job on the main branch, other jobs, dependency versions compared with the last passing run, durations). Apply the first rule that fits. build_or_config: the run failed before any test ran, in compiling, type checking, linting, packaging or the CI configuration itself (a bad pipeline file, a missing secret or variable, a wrong path), even if the change caused it. environment_or_infra: the error comes from the CI machine or an outside service (network or DNS errors, a package registry or mirror down, no disk space, a lost runner, a service container that did not start), not from the code; other jobs often fail the same way. flaky_test: the test fails only some of the time on the same code: a rerun of the same commit passed, or the test fails now and then on the main branch without code changes. timeout_or_resource: a test or job was stopped for exceeding a time limit or a memory limit (out of memory, killed, exit code 137) on every attempt. dependency_change: a third-party package resolves to a different version than in the last passing run (pulled in automatically, or upgraded by the change itself) and the error comes from that package. test_needs_update: the change says this behaviour was changed on purpose, and the failing test still expects the old behaviour. real_regression: the change broke behaviour it did not mean to change: the failure repeats on every attempt and the same test passes on the main branch.

How it was measured

Test accuracy: the share of test rows whose top answer was right.

99.8% on requests from each open specialist's own held-out test data and from public benchmarks, some reworded by an LLM (6,930 rows). mixed sources
99.9% on the requests as written (5,378 rows). mixed sources
99.5% on the requests reworded by an LLM (1,552 rows). mixed sources

When confident

A router picks a specialist for every request rather than holding back, so it has no calibration and no threshold.
