Content And Marking Review Specification

Reviewable Objects

• CalculationProblem prompt, givens, equation, and expected precision.
• SolutionGraph nodes, dependency edges, and accepted expressions.
• MarkingPolicy mark nodes and question-specific ECFRule objects.
• Misconception labels, hint boundaries, and follow-up mappings.

Required Provenance

Every item records object ID/version, source evidence, syllabus identity/cycle, reviewer, review scope, status, timestamp, and superseded version where applicable.

Statuses

• AI_DRAFT: untrusted draft; no authoritative product claim.
• SOURCE_SCOPED: tied to named evidence but not expert approved.
• EXPERT_REVIEWED: approved for the recorded scope.
• RETIRED: unavailable for new attempts; retained for trace reproducibility.

Escalation Reasons

Unsupported path, ambiguous equivalence, missing source evidence, policy conflict, ECF outside the frozen rule, species/equation ambiguity, or reviewer dispute.

V0 may show review metadata and a static queue artifact. It does not add reviewer authentication, production tenancy, or a teacher workflow.
