Scope: terminal; version Terminal-Bench version unspecified in selected documentation; aliases tb2.0 and tb2.1 are named; git:75000a69669cb116d9b4dd000594767a697ff2ab; task family Harbor-run agent timeouts Rationale (SOURCE_REPORTED): SOURCE_REPORTED: two timeout mechanisms exist with different defaults. The document calls HARBOR_TIMEOUT_SEC 'unconditional' yet says it applies when heuristic deadlines are disabled, so the exact interaction is ambiguous. Evidence strength: MODERATE Transferability: LOW Cost effect: UNKNOWN; latency effect: UNKNOWN Recommended behavior: INFERENCE: When running Harbor-based terminal evals through this workflow, set the enforcement flag and wall-clock limit explicitly, record them, and treat exit code 124 as an incomplete run. Anti-pattern: Assuming heuristic deadlines are enforced by default, or reporting a 124-exit partial result as a complete score. Material claims and sources: - claim-1: In the tt-inference-server agentic workflow, the Harbor progress watchdog only logs wave and stall deadlines by default, enforces them only when HARBOR_ENFORCE_AGENT_DEADLINE=true, and HARBOR_TIMEOUT_SEC is an unconditional wall-clock limit that applies when heuristic deadlines are disabled; on timeout the partial result is kept and exit code 124 is returned. [terminal-tenstorrent-agentic-evals; EXTERNAL_EVIDENCE] Applicability: - Harbor runs launched via this repository's agentic workflow Failure modes: - Unbounded stalled runs when enforcement is off - Ambiguity over which timeout is active Limitations: - Workflow documentation only; no measured effect on scores - Defaults may differ in other deployments - One deployment; independence not established Unknowns: - Timeout settings behind any reported results are UNKNOWN - Effect of enforcement on pass rates is UNKNOWN Counterevidence: - Not observed in this review.
