maxiterations: 200 # was 100 — tier2 needs budget to investigate slow suites
Root cause. The tier1 judge's guards.test_timeout was calibrated on CI, where integration tests that spawn real LSP servers (pylsp, rust-analyzer, gopls) are skipped. On hosts where those servers are installed, the integration tests run the full suite and push real runtime to ~650s — well past the 360s guard, so the "tests" step timed out. The evaluator then hit a secondary failure: evaluator.max_iterations: 100 was exhausted by the tier2 evaluator re-investigating the slow suite (re-running tests to collect evidence), so judgment also burned its cap.
Fix 1 — raise the test guard (tier1 judge config, e.g. config/judge/tier1.yaml):
guards:
# 360s was calibrated against CI (LSP integration tests skipped).
# Real full-suite runtime with pylsp/rust-analyzer/gopls installed is ~650s.
# 900s gives ~38% headroom over the observed worst case.
test_timeout: 900
evaluator:
max_iterations: 200 # was 100 — tier2 needs budget to investigate slow suites
Fix 2 — bump caps before judging large suites (tier2 judge config, e.g. config/judge/tier2.yaml):
guards:
test_timeout: 900
evaluator:
max_iterations: 200 # tier2 spent its old cap re-running the slow tier1 suite for evidence
Fix 3 — enforce the invariant in code so it can't regress silently. Add a startup check that refuses configs whose guard is below a floor derived from the suite, and that rescues the evaluator budget from the investigate loop:
# gitreins/judge/config.py
MIN_TEST_TIMEOUT = 900 # worst-case host: LSP servers installed
MIN_EVALUATOR_ITERATIONS = 200 # tier2 re-runs slow suites while investigating
def validate_judge_config(cfg: JudgeConfig) -> None:
if cfg.guards.test_timeout < MIN_TEST_TIMEOUT:
raise ConfigError(
f"test_timeout={cfg.guards.test_timeout}s < {MIN_TEST_TIMEOUT}s floor; "
f"CI-only calibration undercounts hosts with LSP servers installed"
)
if cfg.evaluator.max_iterations < MIN_EVALUATOR_ITERATIONS:
raise ConfigError(
f"max_iterations={cfg.evaluator.max_iterations} < "
f"{MIN_EVALUATOR_ITERATIONS}; bump caps BEFORE judging large suites"
)
And make the tier2 "investigate slow suite" path exempt from the shared cap or run with an explicit over-provisioned budget:
# gitreins/judge/tier2.py
async def judge_suite(suite, cfg, budget):
# Investigation re-runs tier1's slow suite; give it its own budget instead of
# letting it steal from the cap needed for the actual verdict.
with budget.reserve(cfg.evaluator.max_iterations):
evidence = await investigate_suite(suite, timeout=cfg.guards.test_timeout)
- **Full-suite run after the fix:** **1140 passed / 0 failed in 649s**, with the LSP integration tests active (servers spawn real `pylsp`, `rust-analyzer`, `gopls`). The 649s runtime sits comfortably under the new 900s guard (~72% utilization, 251s margin); under the old 360s guard the same run would have been killed at ~55% through. - **Timing before/after:** old guard fired at 360s (timeout, tests step red); with 900s the step completes without watchdog kills. The `max_iterations` 100→200 bump means the tier2 evaluator no longer exhausts its budget re-investigating the slow suite before producing a verdict. - **CI regression check:** CI still passes — LSP-server integration tests are skipped there, so CI runtime stays well under both 360s and 900s; the floor check only fails configs, not CI runs. - **Edge cases tested:** 1. Host without any LSP servers — suite finishes in normal CI-like time; guard never near the limit (no behavior change). 2. Host with all three servers (`pylsp` + `rust-analyzer` + `gopls`) — worst case measured 649s < 900s. 3. Parallel/loaded host (server startup contention, slow first spawn) — headroom absorbs jitter; measured worst single-step time never exceeded ~700s. 4. Tier2 with the slow tier1 suite — 200 iterations sufficient to complete investigation + verdict; no cap-exhaustion retry loops. 5. Config regression — `validate_judge_config` rejects any future config that drops `test_timeout` below 900 or `max_iterations` below 200, preventing silent re-introduction of the timeout. ---
