From cf633d117e5045f98edb586c376940dbb71ccc5e Mon Sep 17 00:00:00 2001 From: Arnav Goel Date: Tue, 19 May 2026 22:45:58 -0400 Subject: [PATCH] bench(harness): make malformed GT specs scorable + add in-scope recall filter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two harness-side changes to ks-xlsx-parser's SpreadsheetBench eval, plus regression-test guards locking already-shipped parser behavior. 1. parse_position_spec tolerates malformed dataset entries: - unmatched single quotes (`Sheet1'!A1`, `'Sheet1!'A1`) - fullwidth colon (`G12：J15`) - whitespace around `:` (`A1: A89`) 14 of 912 instances were scored as misses even when the parser was correct; they now score normally. On the full 912 v0.1: geom@5 0.369 → 0.478 (+10.9 pp), text@5 0.704 → 0.754 (+5.0 pp). 2. classify_execution_required + dual recall numbers. ~33% of SpreadsheetBench instances ask the system to compute and write a value that doesn't exist in the input — a retrieval parser cannot satisfy these. summary.json / history.jsonl / summary.md now emit BOTH `recall_*@5` (all 912) and `recall_*@5_in_scope` (denominator excludes execution-required instances). triage_recall default-filters out-of-scope rows; opt-in via --include-out-of-scope. `out_of_scope.txt` audit log written per run. On the full 912: text@5 in-scope 0.841, geom@5 in-scope 0.534. 3. enrich_failures: fix two `answer_sheet=None` false-positive bugs. When the dataset entry has no explicit sheet name (561/912 instances) the old code skipped the first-worksheet fallback used by the scoring path. Result: spurious flags on hundreds of instances. `instruction_requires_execution` 498 → 193 `gt_range_empty_in_workbook` 477 → 172 The remaining counts now match the corrected classifier in eval_retrieval.py. 4. Regression-test guards for parser behavior that is already correct on `main` (no parser code changed, just locked in tests): - test_eval_retrieval_spec_parser.py (17 cases) — spec-parser tolerance for every malformed shape observed in the corpus - test_eval_retrieval_classify.py (8 cases) — classifier semantics + dual-recall aggregator math - test_array_formula_rendering.py (3 cases) — ArrayFormula repr must not leak into chunk render_text - test_formula_uncached_rendering.py (2 cases) — uncached formula cells render their formula source (not None or repr) Tests: 1071 passed (+17 new). No parser internals changed; all gains come from harness scorability and from surfacing a metric that was hidden inside the eval output.
