# Python Function Repair Records (2026-10-06, deterministic)

**Generated:** 2026-10-06 (run `cr-20261006`, `produced_at` 2026-10-06T00:00:00Z) · **Published to the Hub:** 2026-10-07

> **Rights & intended use:** public **research snapshot**, not training data.
> Deterministic, project-owned generation over real MIT-licensed upstream
> programs (TheAlgorithms/Python @ `2067ce6dfb3`, MIT — see
> `provenance.json`): `intended_use: training_candidate`,
> `project_training_policy: allowed` per the factory registry — but this raw
> snapshot is **not training-ready** (`release-status.json`:
> `release_stage: raw_uncurated_public`, `training_ready: false`).
> Machine-readable record: [`provenance.json`](./provenance.json).
> License: [Apache-2.0](./LICENSE) for generated content; upstream programs
> remain MIT by their authors. There is no `rights.json`: the repo's rights
> schema (v0.1.0) only models hosted-frontier provider routes, so procedural
> rights are declared here and in `provenance.json` instead.

> **Verification:** every candidate carries its execution evidence, but
> independent replay covered only part of the batch: `evidence/REPLAY.json`
> reports 97 of 132 candidates replayed and passed, 0 failed, and 35 not
> replayed (all 22 rejected rows plus 13 accepted rows whose hidden check was
> unavailable); its overall `status: passed` applies to the replayed subset.
> The 132 rows mix 110 accepted and 22 rejected outcomes, with 115 validated
> and 17 provisional oracle statuses (`evidence/RUN.json`); per-row
> `validation.status` is `unvalidated`. `evidence/execution-log.jsonl` is
> harness telemetry, not training rows, and is excluded from the viewer
> projection.

## Contents

132 candidates (110 accepted, 22 rejected) from 150 requested draws: 18 draws
were skipped as duplicate mutants; separately, 4 of the 197 catalog programs
have no mutation sites and were excluded from the draw pool:

| file | records | sha256 |
| --- | --- | --- |
| `data/raw/candidates.jsonl` | 132 | `743327ef7a49`… |

Viewer projection: `data/viewer/records.parquet` (132 rows, lossless
`source_file` / `source_line` / `record_json`; Data Studio `viewer` config).

## Reproduce

From the factory repo:
`python3 pipelines/code_repair_cli.py generate --catalog catalogs/python-repair-v1 --seed 20261006 --count 150 --out <run-dir>`
then `replay --run <run-dir> --catalog catalogs/python-repair-v1 --out <replay-dir>`.
