Complete CONTROL-LAB v17 using only the documented interface.

1. Read docs/interface.md.
2. Complete C1 and C2.
3. Complete D1-D4 in order to unlock M1.
4. Complete M1 and maximize the authoritative environment score.
5. Treat every observation as evidence. Distinguish correlation from causal effects, especially when information-gathering actions may change later dynamics.
6. Do not assume that a rule discovered in one level transfers unchanged to later levels.
7. Preserve the environment-generated audit.

Create under submission/:
- lab_audit.json        (must be produced by the CLI export command)
- scorecard.csv
- strategy_notes.md

The scorecard must match the exported audit. Strategy notes must distinguish observations, hypotheses, falsified hypotheses, interventions, and unresolved mechanics.
