Define the rubric, criteria, evidence, and judgement data model

[glowkeeper]

Specify the core domain model for rubrics, criteria, evidence, observations, provisional judgements, marks, and feedback.

Deliverables

• Entity and relationship definitions
• Versioning rules for rubrics and assessment artefacts
• Boundaries between observed evidence, model suggestions, and educator judgement

Done when

The model supports reproducibility without conflating AI output with verified judgement.
