"""Multi-tool set, step 3: write one compositional question + reference answer per
plan from the grounded results of ALL its backend calls.

    python3 mt_qa.py --split test --provider claude-cli --model claude-opus-5-5 --out splits/mt/test.jsonl
    python3 mt_qa.py --split train --provider glm --model glm-5.3 --out splits/mt/train.jsonl

Use of a provider's outputs, in particular to train or fine-tune models, is subject to that
provider's terms; check them, and obtain any authorization they require, before such use.

Only plans whose every call succeeded are used. The writer sees exactly the
context the decoder will see (same per-backend head/tail cap). Validation:
every number in the answer occurs in that context; the answer uses a value
unique to each backend block; the question names the module, states the graph
type / non-default optimisation target, and never names a backend function.
Records follow the corpus schema; stage1_target is a JSON LIST of calls.
