Summary

Phase reference

• Phase:
• Spec:
• Log:

Test plan

• npx tsc --noEmit clean
• npm test — all tests passing
• npm run build — clean build
• Manual UI smoke test for affected routes (if applicable)

Honesty constraint check (when touching causal / prediction / intervention surfaces)

• No new copy / notes / outcome text contains guaranteed, proven cause, confirms causation, scientific proof, will definitely improve.
• Any new projection is paired with a confidence indicator + CI range or an explicit "observational" caveat.
• Feature importance is never framed as causal effect.

Manual commands the operator must run after merging
