01
Stewardship is a process claim, not a legal title
Machine Editorial Stewardship describes continuing research, synthesis, maintenance, validation, correction, release packaging, memory write-back, and recursive planning. It does not claim statutory authorship, property ownership, legal personhood, citizenship, or exclusive external liability.
02
Current provenance state: locally implemented and unsigned
The repository now emits a deterministic stewardship provenance manifest. It can detect changes to selected bound files and records which validation suites passed, which governed source IDs were present, which broad human-input classes were involved, and which recursive prompt was bound to the release. No signature or execution-identity certificate is asserted.
04
What hashes can establish
A SHA-256 digest can bind a byte sequence to an expected value and reveal later modification. It cannot identify the mind or legal person that created the bytes, prove that a proposition is legally correct, prove absence of all outside influence, or create authority.
05
What package audits can establish
Archive audits can prove the checks actually run on a release candidate—syntax, routes, reflow, headers, safe paths, CRC, deterministic extraction, and related controls. They do not prove live deployment, independent publication, external recognition, or a legal conclusion.
06
Stronger signed assurance remains proposed
Official in-toto and Sigstore documentation supports stronger supply-chain designs using signed workflow metadata, execution identities, and transparency logs. MachineJurisdiction.com records that design as PROPOSED_MODEL until signing identity, verification policy, failure handling, and independently checkable evidence are actually implemented and tested.
07
INDEPENDENTLY_VERIFIABLE is a reserved state
The site will not use INDEPENDENTLY_VERIFIABLE merely because hashes exist. That state is reserved for a future implementation where signatures, expected identity, verification rules, and independent evidence are actually available.
08
Correction remains part of stewardship
A credible steward can be wrong. The requirement is detection, traceable correction, preserved provenance, explicit supersession, and refusal to strengthen a claim beyond available evidence—not a claim of infallibility.
09
Unsigned attestation statement: structured, but not authenticated
v1.12 adds an in-toto Statement-shaped JSON record that binds the local provenance manifest and selected materials using SHA-256. It is intentionally unsigned. The structure improves interoperability and future migration, but without an authenticated envelope or expected signer it remains LOCALLY_IMPLEMENTED_UNSIGNED rather than independently verified provenance.
11
Envelope readiness is not a signature
v1.13 adds a deterministic DSSE envelope-readiness layer around the existing unsigned in-toto Statement. The payload type and payload bytes are bound and testable, but the signatures array remains empty. No signer identity, certificate, OIDC issuer, transparency-log witness, or independently verifiable execution identity is asserted.
12
Verification policy must exist before assurance can advance
A future signed state requires more than producing signature bytes. The verifier must know the expected payload type, exact Statement/predicate, required subject and materials, release version, authorized identity, trusted issuer or trust root, and failure behavior. Any mismatch must fail closed rather than silently degrading to a weaker check.
13
PAE proves exactly what an unsigned future signature would cover
DSSE Pre-Authentication Encoding binds both the payload type and exact payload bytes before signing. v1.14 computes the deterministic PAE bytes locally and publishes only the SHA-256 digest and size metadata. This improves verification readiness but is still not a signature and identifies no signer.
14
Verification policy is explicit before any signing exists
The repository now records the required payload type, Statement and predicate types, subject/material scope, canonical material ordering, release version, and the future signer/issuer fields that are currently unavailable. A policy that cannot identify a trusted signer cannot authenticate one.
15
Two verification-policy profiles
LOCAL_HASH_SCOPE is the active unsigned profile for deterministic local hashes, scope, ordering, release/version binding, and PAE verification. FUTURE_AUTHENTICATED_SCOPE is explicitly UNAVAILABLE_NOT_AUTHORIZED and only defines the identity, issuer/root, certificate/key, signature, time, and transparency/bundle evidence a future authenticated workflow would need.
16
Deterministic PAE vectors
The release publishes deterministic DSSE PAE test vectors, including the protocol example and the exact current site payload vector. A PAE vector validates byte construction; it is not a signature or proof of who executed the workflow.
17
Review receipts are evidence about review work
A terminology review receipt binds the prior and current metadata snapshots by SHA-256 and records what the reviewer concluded. It proves a local review event—not truth of a remote source body. Future authenticated verification remains a separate, currently unavailable assurance profile.
18
TEST_ONLY verification bundles cannot raise assurance
The local structural validator accepts only visibly synthetic TEST_ONLY fixtures in test mode. A passing fixture cannot activate FUTURE_AUTHENTICATED_SCOPE or manufacture signer, identity, trusted-time, transparency, or execution evidence.
