Correct question contracts and references; update rerun results and table

Preserve all 490 public IDs and media paths. Refresh GPT, Muse Spark, and Alibaba Qwen responses and uniformly rescore. One Qwen numeric-MIDI input exceeds the provider limit and retains its historical response, documented in provenance.

+# 2026-10-16 — Corrected question contracts and reruns
+
+Updated eight question/reference rows from this session and synchronized one previously approved pitch-spelling reference from the live editor, preserving all 490 public IDs and media paths. Added corrected GPT, Muse Spark, and Qwen responses, uniformly rescored result exports, and a complete LaTeX table. Qwen uses the Alibaba provider. One Qwen numeric-MIDI rerun exceeds the provider input limit; its historical answer is retained and identified in provenance.
+
+See provenance/question-contract-update.json for full question text, changed fields, coverage, and cost.

 The [offline scorer and usage instructions](evaluation/README.md) are available in `evaluation/`. The package includes the reference normalizer, an optional task-dependent normalizer, a JSONL scoring CLI, and regression tests. The instructions show how to use the existing public question CSV and your own predictions. Scoring requires no model API calls.

+The corrected question contracts and saved reruns are reflected in these results. All 490 current references use the same scorer, including vertical-bar list separators. Metadata and numeric MIDI2 are excluded from the main weighted aggregates; MIDI2 remains a separate ablation. The max is an oracle selecting the best input within each subset. Historical responses outside the requested reruns are retained and marked in the saved predictions.

 ## Ablation
 
-The `ablation` configuration compares MIDI1, which uses named pitches, with
-MIDI2, which replaces them with numeric MIDI note values. The numeric encoding
-substantially reduces overall accuracy for GPT-5.6-sol (55.88% to 29.41%) and
-both Qwen models, while MuseSpark remains at 34.45%.
+Named-pitch MIDI1 and numeric-pitch MIDI2 compare complete serialization choices; controller events, headers, labels, and ordering may differ too. GPT MIDI2 has one missing answer counted incorrect out of 238. Qwen3.6 rows below are retained historical results and were not rerun.
