Where the declaration and the call disagree

None: every capability that was called answered as declared.

Signed certificate

This page’s rows, signed by the observer’s Ed25519 key: every capability’s id, endpoint, safety class, policy class and observed state, the declaration hashes and the record’s sealed manifest. The certificate is derived from the record alone, so the same record always yields the same id.

The certificate as JSON · verify it now · the key directory · machine-readability certificate

To verify it yourself: SHA-256 the certificate object as canonical JSON (keys sorted, no whitespace); the hex digest must equal certificate_sha256 and the id; then check the Ed25519 signature over "crawlcheck-capability-certificate-v1\n" followed by that hex digest, with the key in the directory whose RFC 7638 thumbprint is the kid.

Policy classes

Policy classCalled automatically?Rule
Public read-only
public_read_only
yes, to verifyMay be called without credentials. CrawlCheck calls it only to check the declaration: GET with no input, on the scanned origin.
Authenticated read-only
authenticated_read_only
neverNever called by CrawlCheck. An agent needs the user's own credentials and consent.
Reversible write
reversible_write
neverNever invoked automatically. Needs the owner's written authorisation and a test account.
Irreversible write
irreversible_write
neverNever invoked automatically. Deletes or changes something that cannot be undone.
Financial
financial
neverNever invoked automatically. Moves money or creates a charge.
External communication
external_communication
neverNever invoked automatically. Sends a message, email or notification to someone.
Identity and accounts
identity
neverNever invoked automatically. Creates, signs in to or changes an account or credential.
Unknown
unknown
neverNever invoked. Its effect cannot be read from the declaration, so it is treated as the riskiest case.
Metadata

neverNothing to invoke: a listing, a server card or a skill file, not an operation.
