## Claim and use boundaries

- The exact-half relation is a **conditional classroom mathematical hypothesis**, not a statement that physical paper reliably halves light. Units are explicitly arbitrary and fictional. There is no calibrated uncertainty estimate, engineering recommendation, safety approval, lighting advice or actual experiment from this packet.
- Day 14 actual observation is optional and requires school permission, appropriate low-voltage equipment, supervision and local risk assessment. A paper plan earns planning evidence only. “Not observed” must appear when no approved physical test happened. No public installation.
- The Arts row is evidenced only by an actually created two-panel media artefact; science argument alone does not establish Arts production. An optional digital model run is not automatically a Technology curriculum outcome.
- No place-specific curriculum, First Nations knowledge/language, translation or local permission is asserted. Those require appropriate community and language authority and separate review. Australian Curriculum alignment is partial; this ten-day inquiry does not supply a complete subject or year course.
- The desktop teacher/learner/funder review checks usability, links, arithmetic and language. It is **not** a classroom trial or proof that learners will achieve outcomes.
