# Benchmark record dictionary

All six original CSVs share this schema. Each viewer configuration uses a `records` split because both phases appear in every file.

| Field | Type | Meaning |
| --- | --- | --- |
| `seed` | Integer | Reproducible task-generation seed; development 1–3, held-out 101–120 |
| `condition` | String | `structured`, `asymmetric`, or `constant` input family |
| `method` | String | Compiler or ablation identifier from benchmark code |
| `index` | Integer | Task index in that seed/condition/method sequence |
| `phase` | String | `train` or `fresh`; fresh means a new complete expression |
| `length` | Integer | Number of primitive occurrences in the expression |
| `target` | Integer | Encoded requested boundary group element |
| `work` | Integer | Incremental charged work for the attempted task; excludes initial method setup |
| `ns` | Integer | Instrumented task nanoseconds on original host; descriptive, hardware-dependent |
| `status` | String | Attempt outcome, including exact completion or budget exhaustion |
| `cost` | Nullable integer | Returned optimum cost; empty when no completed answer is available |
| `oracle_cost` | Integer | Optimum from the independent exact oracle |

The group is D_16, with 32 elements. Its implementation and boundary encoding are in `relational_compiler.py`.

The records contain repeated evaluations of corresponding tasks by different methods, not independent draws per row. Development and held-out runs are distinct configurations. Reusable subfragments occur intentionally across phases; complete test expressions are fresh.

Budget files stop when a method exhausts its grant. Remaining tasks do not appear as CSV rows. Aggregate `results.json` files account for those remaining tasks when reporting throughput; do not infer a success rate by dropping absent tasks or dividing by attempted rows alone.

The aggregate JSON files also contain complete per-method work and setup costs. `paper_metrics.json` combines principal and supplementary results. `holdout_summary.json` is the principal-study summary. The supplementary heap comparator has its own directories and was not in the original protocol lock.

Viewer configurations and row counts are listed in `README.md`; this packaging preserves the original CSV bytes.
