Bases: BaseModel

nemo_gym.rollout_reverification.RolloutReverificationHelper.run_from_config(
    config: nemo_gym.rollout_reverification.RolloutReverificationConfig

nemo_gym.rollout_reverification._call_aggregate_metrics(
    results: typing.List[typing.Dict],
    rows: typing.List[typing.Dict],
    output_fpath: pathlib.Path
) -> typing.Optional[pathlib.Path]

async

Call /aggregate_metrics on each resource server after rollouts complete.

Writes a single _aggregate_metrics.json with one entry per agent (same shape as the old _agent_metrics.json). Returns the file path.

nemo_gym.rollout_reverification._check_reverify_mode(
    server_client: nemo_gym.server_utils.ServerClient,
    agent_to_rs: typing.Dict[str, str]
) -> typing.List[str]

async

Query GET /reverify_mode on each unique resource server referenced by agent_to_rs.

Returns a sorted list of RS names that reported ReverifyMode.UNSUPPORTED or ReverifyMode.UNKNOWN.

nemo_gym.rollout_reverification._drop_cache_from_payloads(
    payloads: typing.List[typing.Dict],
    cache: nemo_gym.rollout_reverification.CacheKeysByStatus
) -> typing.Iterator[typing.Dict]

) -> typing.List[str]

nemo_gym.rollout_reverification._guard_atif_preflight(
    payloads: typing.List[typing.Dict[str, typing.Any]]
) -> None

async

Validate selected routes before ATIF reverification touches output paths.

nemo_gym.rollout_reverification._guard_reverify_mode(
    config: nemo_gym.rollout_reverification.RolloutReverificationConfig
) -> typing.Optional[str]

async

Check reverify_mode for every RS in the config before reverification starts.

Returns a warning string when the user runs full re-verification (not judge-failed-only) and force=True and at least one RS is UNSUPPORTED or UNKNOWN (caller must print it and apply the unsafe_ output prefix). Raises ConfigError when force=False and at least one RS is UNSUPPORTED or UNKNOWN. Returns None when all RS are STATELESS.

nemo_gym.rollout_reverification._is_judge_failure(
    row: typing.Dict[str, typing.Any]
) -> bool

Whether a failures-sidecar row is a judge failure (the only recoverable class).

nemo_gym.rollout_reverification._load_cache_keys_by_status(
    output_fpaths: nemo_gym.rollout_reverification.OutputPaths
) -> nemo_gym.rollout_reverification.CacheKeysByStatus

nemo_gym.rollout_reverification._load_reverified_results(
    output_fpath: pathlib.Path
) -> typing.Tuple[typing.List[typing.Dict], typing.List[typing.Dict]]

Load the full main jsonl (cached + newly re-verified successes), sorted by (task, rollout).

Returns (results, rows): results are the parsed rows — the source of truth used for both the W&B rollouts export and the aggregate-metrics payload; rows is a minimal {agent_ref, task_source} projection used only to route each result to its resources server (with the same resolver as /verify). Read once and reused for both so the file is never read twice.

nemo_gym.rollout_reverification._parse_output_line(
    line: bytes
) -> typing.Dict[str, typing.Any]

nemo_gym.rollout_reverification._parse_output_line_key(
    line: bytes
) -> tuple[int, int] | None

nemo_gym.rollout_reverification._prepare_atif_payloads(
    materialized_inputs_jsonl_fpath: pathlib.Path,
    atif_manifest_jsonl_fpath: pathlib.Path,
    limit: typing.Optional[int] = None
) -> typing.List[typing.Dict]

Build verifier payloads from an explicit ATIF-to-materialized-task manifest.

nemo_gym.rollout_reverification._prepare_output_fpaths(
    output_name_prefix: str,
    output_jsonl_fpath: str,
    resume_from_cache: bool,
    overwrite: bool,
    append: bool
) -> nemo_gym.rollout_reverification.OutputPaths

nemo_gym.rollout_reverification._prepare_payloads(
    materialized_inputs_jsonl_fpath: pathlib.Path,
    rollouts_jsonl_fpath: pathlib.Path,
    output_fpaths: nemo_gym.rollout_reverification.OutputPaths,
    resume_from_cache: bool,
    limit: typing.Optional[int] = None,
    rollout_predicate: typing.Optional[typing.Callable[[Dict[str, Any]], bool]] = None
) -> typing.List[typing.Dict]

nemo_gym.rollout_reverification._recovery_rollout_predicate(
    skip_keys: typing.Optional[set[tuple[typing.Any, typing.Any]]] = None
) -> typing.Callable[[Dict[str, Any]], bool]

Build the row filter for --judge-failed-only recovery.

Keeps only judge-class failures, skips any whose (task, rollout) key is in skip_keys (the keys already present in the output: seeded successes + rows a prior recovery already appended) so a key-in-both is never re-verified/duplicated and re-runs are idempotent — this dedup is done here, independent of the resume/cache machinery — and dedups on the key so a sidecar with multiple failure attempts for one key re-verifies it exactly once.

nemo_gym.rollout_reverification._resources_server_exposes_tools_over_mcp(
    global_config_dict: typing.Union[typing.Dict[str, typing.Any], omegaconf.DictConfig],
    resources_server_name: str
) -> bool

Read the selected resources server’s MCP exposure flag from Gym config.

nemo_gym.rollout_reverification._response_has_function_calls(
    row: typing.Dict[str, typing.Any]
) -> bool

nemo_gym.rollout_reverification._rollout_verify_debug_summary(
    row: typing.Dict[str, typing.Any],
    resources_server_name: str
) -> typing.Dict[str, typing.Any]

nemo_gym.rollout_reverification._rs_for_row(
    row: typing.Dict[str, typing.Any],
    agent_to_rs: typing.Dict[str, str],
    global_config_dict: typing.Union[typing.Dict[str, typing.Any], omegaconf.DictConfig]
) -> str

The resources server that verifies this row.

A task_source naming a resources server is authoritative (it is the declaring instance the dataset was stamped with — no agent indirection needed). Otherwise fall back to the rollout’s agent_ref via the config’s agent->rs edges.

nemo_gym.rollout_reverification._run_verification_payloads(
    payloads: typing.List[typing.Dict],
    semaphore: asyncio.Semaphore | contextlib.nullcontext[None] | None = None
) -> typing.Iterator[asyncio.Future]

nemo_gym.rollout_reverification._seed_output_with_successes(
    successes_fpath: pathlib.Path,
    output_fpath: pathlib.Path
) -> set[tuple[int, int]]

Copy the already-successful rollout rows into the output file so the final aggregate covers successes + recovered rows, and return the set of (task, rollout) keys ALREADY PRESENT in the output afterward

nemo_gym.rollout_reverification._selected_atif_resources_server_routes(
    global_config_dict: typing.Union[typing.Dict[str, typing.Any], omegaconf.DictConfig],
    payloads: typing.List[typing.Dict[str, typing.Any]]
) -> typing.List[str]

Resolve each ATIF row through the same routing policy used by /verify.

nemo_gym.rollout_reverification._yield_inputs_and_rollouts_paired(
    materialized_inputs_jsonl_fpath: pathlib.Path,
    rollouts_jsonl_fpath: pathlib.Path,
    limit: typing.Optional[int] = None,
