+# ORBench problems and recorded results
+
+100 synthetic inventory, assignment, and scheduling instances for the ORBench demo.
+
+Organization dataset and collection are public. Live Gradio and the organization card are created by `scripts/publish.py`. Runnable Space source is stored in `demo/`. Collection: [Aria AI — OR + LLM Evaluation](https://huggingface.co/collections/AriaAICompany/aria-ai-or-llm-evaluation).
+
+Generated data, seed 25. All identifiers are synthetic. Gold objectives come from OR-Tools CP-SAT on the same schema that ships in each row. LLM rows in `results.jsonl` are explicitly `not_evaluated`.
+
+## Files
+
+- data/problems.jsonl
+- data/results.jsonl
+- data/leaderboard.csv
+- data/splits.json
+- data/sample_preview.json
+- data/protocol.md
+- demo/ — runnable Gradio Space source
+- showcase/ — organization static card
+
+## Splits
+
+- development: 60 instances, templates `D-A` / `D-B` / `D-C` with a `SCHEMA_BEGIN` block
+- test: 40 instances, templates `T-A` / `T-B` in prose
+- interactive: 20 ids listed in `splits.json`
+
+Development and test do not share `(family, template_id)` pairs. Near-duplicate prompt templates are therefore not reused across the split.
+
+## Metrics
+
+Independent validators recompute inventory balance, pack multiples, budget, capacity, assignment uniqueness/eligibility/capacity, and schedule overlap/precedence/release. Optimality gap is reported only when gold status is `optimal`. An unevaluated method is never written as 0.
+
+## License

+# ORBench reproduction protocol v1
+
+Seed: 25. Code version: 0.1.0. Solver: OR-Tools CP-SAT, 1 thread, 6–8 seconds.
+
+1. Generate the catalog with `python scripts/build_artifacts.py`.
+2. Each problem stores `schema_payload`, bilingual prompts, `gold_status`, `gold_objective`, and `gold_solution`.
+3. Evaluated methods: `structured-solver`, `heuristic`, `json-extractor+solver`, `template-extractor+solver`, `naive-direct`.
+4. Listed but not run: `Qwen/Qwen3-4B-Instruct-2507`, `Qwen/Qwen3.8-27B`, `moonshotai/Kimi-K3`, `zai-org/GLM-5.3`, `deepseek-ai/DeepSeek-V4.1-Flash`. Cells are `not_evaluated`.
+5. Gap = max(0, (method_obj − gold_obj) / max(1, |gold_obj|)) only if gold status is optimal and the method plan is feasible.
+6. Paid APIs stay off. Do not substitute a second paid provider when the first is missing.
+7. Synthetic results in this dataset are not customer data.
+
+Run `pytest tests/test_pipeline.py` after generation. A passing suite is the acceptance check for constraint validation, split hygiene, and honest unevaluated cells.

+# ORBench — Solver and Agent Decision Benchmark
+
+**Aria AI** research prototype. Teams want to know whether a new model can recover constraints and produce a *valid* decision. A fluent paragraph is not a feasible plan. The numeric validator is the judge.
+
+The MVP is 100 small synthetic instances from inventory, assignment, and scheduling, with a 60/40 development–test split and 20 interactive samples. Three comparison paths are recorded: structured form + CP-SAT, text → schema → solver, and a fixed heuristic. A naive direct answer is included only as a labeled benchmark, not as an operational planner.
+
+## What you can do
+
+1. Load one of the 20 interactive problems (English or Persian).
+2. Compare CP-SAT, lot-for-lot / greedy / EDD, JSON extraction, template extraction, and a naive direct answer.
+3. Hide a hard constraint in the prompt and watch fidelity drop.
+4. Filter the recorded 100-problem table by family, split, language, or difficulty.
+5. Download the comparison CSV and the JSON report.
+
+CPU only. No paid API. Named Hub models (Qwen, Kimi, GLM, DeepSeek) stay **not_evaluated**. That cell is not a zero and not a rank.

+# ORBench reproduction protocol v1
+
+Seed: 25. Code version: 0.1.0. Solver: OR-Tools CP-SAT, 1 thread, 6–8 seconds.
+
+1. Generate the catalog with `python scripts/build_artifacts.py`.
+2. Each problem stores `schema_payload`, bilingual prompts, `gold_status`, `gold_objective`, and `gold_solution`.
+3. Evaluated methods: `structured-solver`, `heuristic`, `json-extractor+solver`, `template-extractor+solver`, `naive-direct`.
+4. Listed but not run: `Qwen/Qwen3-4B-Instruct-2507`, `Qwen/Qwen3.8-27B`, `moonshotai/Kimi-K3`, `zai-org/GLM-5.3`, `deepseek-ai/DeepSeek-V4.1-Flash`. Cells are `not_evaluated`.
+5. Gap = max(0, (method_obj − gold_obj) / max(1, |gold_obj|)) only if gold status is optimal and the method plan is feasible.
+6. Paid APIs stay off. Do not substitute a second paid provider when the first is missing.
+7. Synthetic results in this dataset are not customer data.
+
+Run `pytest tests/test_pipeline.py` after generation. A passing suite is the acceptance check for constraint validation, split hygiene, and honest unevaluated cells.

+ORBench is a research prototype for comparing decision-making *methods*, not a ranking of companies or a production optimizer.
+
+**What it decides.** For each tiny instance it records parse success, constraint fidelity, feasibility, and optimality gap versus a gold CP-SAT run. An LLM score is never the judge.
+
+**Three families.** Inventory (pack multiples, budget, warehouse capacity, optional hard cover), assignment (skill + capacity), and scheduling (release, precedence, optional hard due dates). Lead time is 0. Units are abstract.
+
+**Methods actually run.** `structured-solver`, `heuristic`, `json-extractor+solver`, `template-extractor+solver`, `naive-direct`. Development prompts include a `SCHEMA_BEGIN` block; test prompts are prose so the template extractor can fail honestly.
+
+**Methods listed but not run.** Qwen, Kimi, GLM, and DeepSeek cards stay `not_evaluated`. That cell is not a zero and not a rank.
+
+**Validator.** An independent checker recomputes inventory balance, pack, budget, capacity, assignment uniqueness/eligibility/capacity, and schedule overlap/precedence/release. Gap is reported only when gold status is optimal.
+
+**Limits.** 100 synthetic instances, CPU only, no paid API, no agent tool-use environment in this MVP, no claim that a fluent answer is operationally safe. Direct LLM-style answers are labeled benchmark-only.
