Make the budgets close.
The same spacecraft model at all six academic depths. Nothing below is written by hand — every cell is read from the disclosure layer the lesson actually uses.

What each depth is asked to produce
These requirements drive which inputs the learner sees.
| Depth | Prediction | Two cases | Plot or table | Explanation | Limitation | Provenance |
|---|---|---|---|---|---|---|
| Grades 9–10 | Yes | Yes | Yes | Yes | Yes | Yes |
| Grades 11–12 | Yes | Yes | Yes | Yes | Yes | Yes |
| University | Yes | Yes | Yes | Yes | Yes | Yes |
Which evidence channels are visible
A channel hidden at a depth is removed on the server. It never reaches the learner's browser.
| Channel | Grades 9–10 | Grades 11–12 | University |

| mission state | Yes | Yes | Yes |
Learner wording and curriculum wording
Learners read the mission in plain language. The curriculum phrasing signed off in the frozen academic layer is unchanged, and is shown here so you can map one to the other.
| Step | What the learner reads | Academic phrasing |
|---|---|---|
| Mission question | Two designs, one mission. Which one actually closes every budget it has to? | Which bounded spacecraft configuration best satisfies the stated mission criteria? |
| Theory | Two designs, the same mission. Each is checked against its own stated limits, and every check has to hold. | Define quantities, units, and the comparison you will calculate. Stage intent: compare two profiles. |
| Prediction | Before you run anything: which design do you expect to close every budget, and which check worries you most? | Predict a quantitative difference between baseline and candidate. |
| Run | Compile the trainer design first, then the engineering design. The mission is identical. | Execute baseline/candidate Twin runs and export a table or plot. Runtime remains the frozen Twin; this plan does not execute physics. |
| Analysis | Read every check, not the headline. One budget that does not close is enough to stop a design. | Calculate, model, compare, and test using simulated evidence only. Evidence intent: configuration record + trade matrix + justified design choice. |
| Decision | Which configuration would you take forward, and which checks decided it? | Recommend the candidate with quantitative support and stated uncertainty. |
| Limitation | Name one thing this configuration study does not establish about a real spacecraft. | Name at least one frozen-model limitation that this experiment cannot answer. |
