Adds examples/structured-output-accuracy, the runnable example behind https://superlinked.com/structured-output.

It scores seven models' strict structured-output APIs on 500 records of the public Structured Output Benchmark (SOB, interfaze-ai/sob), with SOB's own prompt, strict-schema normaliser and evaluate_record fetched at a pinned commit and imported unmodified. It also scores 150 NHTSA vehicle complaints filed in September 2026 against the agency's own coding, and a 100-record repeat for repeatability and latency.

  • fetch.py (standard library): downloads the recorded responses from superlinked/sie-task-evidence at revision 0e1fb325cf25bd403ff678dd6031f649981eb434 (structured-output-accuracy/), the SOB parquet and SOB's scorer at pinned revisions, each checked against its digest.
  • score.py: offline; re-derives every figure (value accuracy, a lenient reading, paired bootstrap intervals against SIE, tokens and $ per 1M documents at list and batch price). No API key.
  • run.py: --show prints any request body offline; --record re-sends requests to SIE (and optionally the other vendors).

Headline (values exactly right, 500 records): SIE Qwen3.8 27B 83.5%, Claude Haiku 4.5 80.4%, Claude Sonnet 5 79.3%, GPT-6 Sol 77.7%, Claude Sonnet 5.5 77.2%, Claude Opus 5.5 76.9%, GPT-6 Luna 76.6%. On the lenient reading and on the fresh complaints the models are level; the README says so.

Checked: fetch.py from the dataset then score.py end to end; ruff; tools/ci/check_public_tree.py.

🟡 Minor · Exclude schema rejections from repeat scoring. · score.py:422-448

examples/structured-output-accuracy/score.py:422-448
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exclude schema rejections from repeat scoring.

run.py records schema rejections with error=None, rejected, and empty text. score_repeat filters only error, so two rejected calls compare as identical empty answers. Rejected calls also increase n, which is printed as answered and used as the identical-answer denominator.

Suggested fix
-        again = {rid: row for rid, row in scored_rows(path).items() if row.get("error") is None}
+        again = {
+            rid: row
+            for rid, row in scored_rows(path).items()
+            if row.get("error") is None and not row.get("rejected")
+        }
         first_path = calls / "e1" / path.name
         first = scored_rows(first_path) if first_path.exists() else {}
         same = [
             rid
             for rid, row in again.items()
-            if first.get(rid, {}).get("error") is None and canonical(first[rid]["text"]) == canonical(row["text"])
+            if (
+                first.get(rid, {}).get("error") is None
+                and not first[rid].get("rejected")
+                and canonical(first[rid]["text"]) == canonical(row["text"])
+            )

Fixed the remaining repeat-scoring finding in d7c404d: rejected schemas are excluded from answered calls and baseline comparisons; missing baseline IDs are handled safely. A focused offline fixture verified the rejection and missing-baseline cases, and Ruff passed. @coderabbitai review

Updated repeat accuracy in a5abd13 to use only valid baseline-repeat pairs, while retaining all successful repeat calls for latency and token statistics. With no valid pairs, the comparison is unavailable. A focused offline fixture passed rejection, missing-baseline, paired-denominator and no-pair cases; Ruff passed. @coderabbitai review

🟡 Minor · Exclude malformed JSON from repeatability pairs, not from performance totals. · score.py:425-450

examples/structured-output-accuracy/score.py:425-450
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exclude malformed JSON from repeatability pairs, not from performance totals.

score_repeat filters paired only by error and rejected, so malformed successful completions enter the denominator. Because canonical preserves malformed text, two identical malformed completions can also increase identical. This can overstate repeatability. Filter parseable JSON when building paired, but keep again unchanged so n, latency, and token statistics still include every successful non-rejected call.

Suggested fix

+            try:
+                json.loads(text)

+                return False
+            return True

Addressed the final outside-diff finding: repeat comparison pairs now require parseable JSON in both answers, while every successful non-rejected completion remains in performance totals.
