SynthWorld Frozen Benchmarks

Deterministic, connected synthetic identity graphs and agent-authority traces with ground-truth answer keys, for testing privacy, PII extraction, entity resolution, exposure analysis, identity attribution, delegated authority, temporal validity, and audit provenance — without collecting or fabricating data about real people.

These artifacts are the frozen golden benchmarks of the SynthWorld generator (pip install idcognito-synthworld, v0.9.0+). They are generated from seed 20260719 and authenticated by SHA-256 manifests. Generator CI recreates the artifacts byte-for-byte and fails on drift, so results remain tied to exact benchmark bytes.

Every record is unmistakably fake

Safety is mechanical and enforced by the generator's models and tests:

every persisted object carries synthetic: true;
emails use the reserved example.test domain;
phones use a fictional 555-01xx range;
addresses use example-named streets in Testville, postal code 00000, country ZZ;
national identifiers carry a SYN- prefix with deliberately invalid checksums;
agentic credentials contain opaque identifiers and validity metadata, never reusable secret material.

This dataset must never be used to impersonate, target, or investigate a person. No real person's data was used.

Authoritative data and viewer projections

frozen/ contains the authoritative artifacts shipped by the Python package. viewer/ contains derived JSONL tables for convenient browsing. Viewer-created Parquet files and the viewer/ projections are not checksum authorities; use the raw files under frozen/ when reproducing or comparing scores.

The identity/privacy benchmark files retain their per-file SHA-256 values:

File	SHA-256

Asteria Agentic v1

Asteria is a small, inspectable procurement conformance world for agent identity and delegated authority. It contains two organisations, four Asteria departments, ten principals, three logical agents, three runtimes, four grants, nine resources, 24 ordered events, and 11 positive and negative action cases.

The authoritative tree is:

frozen/asteria-agentic-v1/
  public/       # input for the system under test
  evaluator/    # answer-key material used only after predictions exist

The public and evaluator roots are independently bound with the sha256-artifact-set-v1 convention:

Tree	Artifact-set digest
`public/`	`9ef217b5d604f42a68b7c97596c550698293f1a44f402dbc3d39a2cef19c4594`
`evaluator/`	`3d856f39a5c34ca891ec61298a40ee5bfcb134feae5db7b8a20f6ce9078b2b3f`

The public manifest.json and evaluator checksums.json are excluded from their own root digests. Each root hashes the sorted relative path, a NUL byte, and the raw SHA-256 digest of every listed base artifact. Both metadata files also carry per-file hashes.

The answer key is deliberately public in this repository. The physical split prevents accidental label leakage in an integration; it is not an anti-cheating boundary. Competitive evaluation requires held-out private worlds.

Use Asteria

Install v0.9.0 or later and export the frozen package:

The SynthWorld Python package requires Python 3.12 or newer; Python 3.11 and earlier are not supported.

pip install idcognito-synthworld
synthworld generate-agentic --output asteria-agentic-v1

Give only asteria-agentic-v1/public/ to the system being evaluated. It must emit one nullable ObservedActionTrace JSON object for each action event. Then score the JSONL trace locally:

synthworld evaluate agentic \
  --predictions observed-actions.jsonl \
  --summary

The report keeps identity resolution, action-time authority, audit-time temporal validity, least privilege, attribution, ownership, delegation-chain integrity, provenance, reconstructability, policy version, and side effects as separate metrics. There is no aggregate score that can hide a weak dimension.

See the complete Asteria guide for the JSONL contract, replay semantics, runnable public-only baseline, and Python API.

Other benchmark families

golden-v1.json contains ten connected personas, nine evidence-backed relationships, and scripted breach, broker, search, and social histories.
extraction-public-golden-v1.json and extraction-answer-golden-v1.json separate 62 product-safe pages from their exact character-span answer keys. extraction-golden-v1.json is the joined evaluator convenience bundle.
connection-public-golden-v1.json contains 18 opaque adversarial identity records; connection-golden-v1.json carries the entity and relationship truth.
risk-public-golden-v1.json separates provider-neutral observations from the score, band, and factor truth in risk-answer-golden-v1.json.

Public input and evaluator truth

Answer keys exist so evaluators can score predictions; a system that reads its own answer key is not being evaluated. Give products and models only files explicitly described as public. Join evaluator data after the system has produced its predictions.

Because the golden answer keys are published, this separation is an API-hygiene guarantee rather than a secrecy claim. The same split can be used with private held-out worlds for adversarial or leaderboard evaluation.

Quick start with the viewer tables

from datasets import load_dataset

pages = load_dataset(
    "Bluntmachetti7/synthworld-benchmarks",
    "public_extraction_pages",
)
principals = load_dataset(
    "Bluntmachetti7/synthworld-benchmarks",
    "asteria_principals",
)

print(pages["golden"][0]["content"])
print(principals["golden"][0])

Download the authoritative Asteria event stream rather than a Viewer-derived projection:

from huggingface_hub import hf_hub_download

events_path = hf_hub_download(
    "Bluntmachetti7/synthworld-benchmarks",
    "frozen/asteria-agentic-v1/public/public_events.jsonl",
    repo_type="dataset",
)
print(events_path)
