Baseline job

Record an identified reviewer’s independent check and attestation.

What the tag can claim

A person attested to a defined review; the signature alone does not establish truth.

Method and evidence

• Human attestation only, with a defined signing and challenge policy.
• Development · standard v0.1.0
• Not applicable: human attestation.

Input

An identified artifact, reviewer evidence, and authorized attestation.

Output

A versioned tag record with subject binding, method, evidence, limitations, and a result state.

Supported scope

• Human review is the intended basis

Limits

• Never machine-assigned
• Reviewer independence and review scope must be checked
• Not a universal guarantee

Accuracy and validation

Not independently release validated.

Cost and access

Free personal workflow. No paid detector, evidence, or verification gate.

Privacy

This catalogue does not evaluate your content. The personal reference implementation uses local services; detected redaction can miss sensitive information.

Dependencies

• Versioned claim and evidence contract
• Independent review for this tag
• Accessible presentation and a clear failure state

Failure behavior

A failed or unsupported check must not become a finding. A problem with this tag must not disable unrelated tags.

Who owns the outcome

Maintainers own implementation; independent reviewers own validation; the product owner accepts release.

Before release

Publish agreed acceptance criteria, run independent validation, and verify the complete user workflow before release.
