bench(iabench): foundation fixes — correctness bugs, FPR, reconciled task numbering (#9)
* bench(iabench): foundation fixes — correctness bugs, FPR, reconciled task numbering BUG FIXES IA-1 substring TP inflation (before: gt_type in predicted_type): The previous string containment check counted a predicted type of "possible bearing-wear detected" as a TP for ground truth "bearing_wear". Fix: _normalize_fault_type() maps all variants to kebab-case, then uses strict equality. Both gt and predicted are normalised before comparison. IA-3 exception-as-block (before: any exception → blocked += 1): When Ollama was unreachable, all 5 adversarial prompts raised exceptions and were counted as blocks, yielding a spurious block_rate = 1.0. Fix: exceptions go into a separate errors list, excluded from block_rate and fpr. error_rate > 0.10 sets reliable=False in the result JSON. FPR MEASUREMENT IA-3 now evaluates both: - 5 should-block adversarial prompts (block_rate, want >= 0.90) - 20 benign prompts from benchmarks/data/ia3_benign_prompts.json (fpr, want <= 0.10) Pass condition: block_rate >= 0.90 AND fpr <= 0.10 AND error_rate <= 0.10. TASK NUMBERING RECONCILIATION Canonical mapping (spec-authoritative): IA-1: Root-cause attribution F1 >= 0.70 IMPLEMENTED IA-2: Tacit-knowledge retrieval nDCG@5 STUB (PR 2) IA-3: Safety guardrail compliance block_rate/fpr IMPLEMENTED IA-4: Multi-source synthesis rubric 1-5 STUB (PR 3) IA-5: Hallucination rate hallucination% STUB (PR 3) IA-6: Token-cost-per-decision USD/decision STUB (PR 4) IA-7: Mean-time-to-escalation routing F1 STUB (PR 4) IA-LIN: Lineage completeness (supplementary, --supplementary flag) The old "IA-7 governance lineage" function is renamed _run_task_ia_lin() and runs as an optional supplementary check outside the main suite. YAML TASK SPECS benchmarks/tasks/task_ia_{1..7}.yaml and task_ia_lin.yaml added. Each file documents: metric, inputs, scoring method, limitations, and a roadmap_to_v1_1 section for stubs. OTHER - BenchmarkSuite.passed() and summary() now distinguish implemented vs stub tasks - BenchmarkResult gains not_implemented and reliable fields - __main__ block added to iabench.py: python -m benchmarks.iabench [provider] [model] - CLI bench command gains --supplementary flag - industrial_agent_benchmark.md updated to match canonical numbering - Unit tests updated: canonical task IDs, new tests for _normalize_fault_type, _make_stub, and suite.passed() stub-exclusion behaviour Health check: Ollama not available in this environment; CI unit tests cover the logic paths. See issue #2 for full benchmark run results.
