Baseline job

Identify claims contradicted by supplied reference material.

What the tag can claim

Reference contradiction or an unverified citation requires bounded wording; absence of support alone does not establish fabrication.

Method and evidence

• Proposed local corpus contradiction and citation checks.
• Development · standard v0.1.0
• 0.75 editorial proposal; uncalibrated.

Input

Content and a local reference corpus.

Output

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

Supported scope

• Planned corpus contradiction with inspectable spans

Limits

• An incomplete corpus cannot prove a citation does not exist
• A contradiction can reflect an incorrect reference
• No intent or dishonesty finding

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.
