TrainingProject return contract (dictionary shapes)
from_file: validates configuration, attaches its owned run; no weight updates.
plan: {schema_version, resolved_configuration, compatibility, data_sharing,
       budgets, topics, artifacts, fingerprints}; dry_run must be true.
run/resume: {run_id, status, stop_reason, report_path, unmet_criteria}.
status/pause/cancel: {run_id, status, stop_reason, report_path, unmet_criteria}.
stop_reason is null until terminal; run/resume block until terminal or paused.
pause blocks until owned workers acknowledge an atomic checkpoint.
cancel blocks until owned workers stop; a failed stop raises CancellationError.
evaluate: {run_id, split, accepted, criteria, regressions, report_path}.
export: {run_id, format, artifact_path, manifest_path, sha256}.
Returned paths are local, resolved paths; no model upload is implied.
Status output is redacted and may be read without opening an API connection.
from_file requires path: str | os.PathLike and a nonempty api_key: str.
plan accepts dry_run=True only; False is ConfigurationError, not execution.
evaluate accepts split="validation" or "test"; defaults to test.
export accepts safetensors or adapters when supported by the selected adapter.
All method keyword options are keyword-only. Unlisted arguments are rejected.
