csoai-gspc

Read the live GSPC AI-governance board and verify its Ed25519-signed measurement cards.

GET https://councilof.ai/api/gspc is the authority. This package is a reader: it never caches a verdict, never prints a number the board did not return, and reports three states and only three.

pip install "csoai-gspc[verify]"

The verify extra pulls in cryptography for the Ed25519 check. Without it the library still reads the board; card verification then returns UNCHECKABLE, which is the honest answer and not a silent pass.

Three states, never two

UNCHECKABLE is a different claim from INVALID. "I could not check" is not "it is forged", and this library never collapses the two. bool(verdict) is true only for VALID.

Command line

$ csoai-gspc check
{"agree": true, "printed_slots": …, "printed_measured": …,
 "derived_slots": …, "derived_measured": …, ...}   # the numbers are whatever the live array holds
OK — the printed totals are derived from the axis array, not typed.

$ csoai-gspc board          # every slot, its bench, its n, its frozen bank
$ csoai-gspc axis governance
$ csoai-gspc verify acf6bf0356123632758bf6c98c83d81c7a8392c3b111b311317c516cc65133a4
VALID — acf6bf0356123632 · id and signature check under the pinned key
$ csoai-gspc root           # the Merkle root over the published cards
$ csoai-gspc snapshot       # the dated snapshot bundled with this release — not the live GET

check exists because a headline count is worth nothing if it was typed. It fetches the board, recomputes the slot and measured counts from the axis array, and exits non-zero if the printed totals disagree — so you can refute us with our own payload.

Library

from csoai_gspc import fetch_board, check_totals, get_axis, fetch_card, verify_card, pinned_key

board = fetch_board()
assert check_totals(board)["agree"]

gov = get_axis("governance", board)
print(gov["bench"], gov["n"], gov["status"])     # bench, n and status exactly as the board carries them

key = pinned_key()                                # from https://councilof.ai/.well-known/did.json
v = verify_card(fetch_card("acf6bf03…65133a4"), key)
print(v.state, v.reason)

Pin the key. This step is not optional

A card carries its own pubkey. Verifying a card against the key it ships with proves only that the file is self-consistent — anyone can alter a body, sign it with a key made a second ago, and have it "verify". pinned_key() reads did:web:csoai.org#card-attestation-1 from the published DID document, and verify_card returns INVALID when a card's key is not that one.

Why this library is written in Python

The published preimage rule is CPython's own serialiser:

json.dumps(body, sort_keys=True, separators=(",", ":"), ensure_ascii=True).encode("utf-8")

CPython renders a float of integral value as 0.0. ECMAScript JSON.stringify, Go's encoding/json and RFC 8785 (JCS) all render the same value as 0. A naive verifier in those languages computes a different preimage and reports a false failure on roughly a third of the published set. In Python the rule reproduces exactly, so this package needs no canonicalisation shim — and you should not re-canonicalise a published card with JCS.

Tests run against the published bytes

There are no fixtures and no mocks. The suite fetches the real DID document and a real card, asserts the documented key, asserts the preimage rule reproduces the published id, and asserts that altering one character or substituting the key is loud.

What this is not

Not a certification, not a rating, not an endorsement, and not legal advice. A card is evidence of what specific bytes scored on a frozen bank at a specific time. No slot is for sale.

This release ships a dated snapshot of the board at csoai_gspc/snapshot/ (board.json, root.json, SNAPSHOT.json), read at 2026-09-05T12:42:38Z. csoai-gspc snapshot prints it. Every other command still reads the live GET at request time; the live GET is the authority and this bundle is only what it said on that day. spray-fingerprint: ea677ca9b6fefcf4d56a29e4c994b5d30bff9ef875276c4c165b0d4a9323acb9
