tool-parity — the open-source estate behind every industry MEOK touches

Measurement, not certification. This dataset measures repositories. It never certifies a tool.

What this is

A reproducible measurement of the open-source software estate behind the industries MEOK works in, taken from public repository state — read directly from the GitHub API and raw endpoints, not from what any project says about itself.

• axis: tool-parity
• card kind: gspc.measurement-card
• card id (sha256 of the canonical body): 1332ad3c1da0947439b3d812ca40597ce3585117248d07f0db824859b44f290e
• signing key: did:web:csoai.org#estate-chain-1 (published in did:web:csoai.org, pinned in the Council of AI verifier)
• measured at: 2026-10-25T05:18:48.356713+00:00
• repositories measured: 100
• fetch failures: 0
• estate repositories: 68
• headline apps: 15
• dormant (>400 days since last push): 32
• licence states: permissive 46 · stated with obligations 8 · licence-unstated 46

Every repository carries exactly one licence state, and the three counts sum to the number measured. A repository with no stated licence is recorded as licence-unstated — never quietly counted as permissively licensed, and never counted as forbidden. "Unstated" is a null, and the null is published.

Verify it yourself

# the Council's own published verifier
curl -O https://councilof.ai/signed/verify-card.mjs
node verify-card.mjs parity.card.signed.json

The card's preimage rule is json.dumps(body, sort_keys=True, separators=(',',':'), ensure_ascii=True).encode('utf-8') and its id is the sha256 of those bytes.

The card binds this snapshot's content digest — c03c6fb10c7ab736501ab7a30f2a30b3cd1a59eadd39f49246584fe38330c08c — computed as sha256(json.dumps(snapshot_body_without_content_sha256, sort_keys=True, separators=(',',':')).encode('utf-8')). It is formatting-independent: reformatting the file cannot change it. MANIFEST.json records that content digest alongside the file-byte digest of the exact published bytes.

Reproduce it

python3 measure_parity.py --out parity_snapshot.json

An unchanged estate reproduces the same snapshot digest; a changed estate produces a changed digest and a diff — not a claim. The card states the digest it was signed over, so any re-run either matches the card or tells you the world moved.

Measurement, never certification. Verification is free, forever, for anyone.

Read this product

This is a structured evidence archive, not a training table. The automatic table viewer is disabled because the repository contains documents with different schemas, signatures or timestamp proofs. All original evidence files remain available.

import json
from huggingface_hub import hf_hub_download

For reproducible reuse, pass the repository commit SHA as revision and retain the downloaded bytes. Loading a file does not verify its signature; follow this card's verification instructions before relying on a claim. Dated snapshots remain historical measurements.
