You are implementing task **{current_task}** for the Investor Flow project.

Read the SPEC.md at `.automaton/tasks/{current_task}/SPEC.md` carefully.

## Rules
1. Follow ADR-0007: no trade verbs (buy/sell/cut/trim), educational framing only
2. All existing tests must pass: run `node --test --experimental-strip-types`
3. Pure/cache-deterministic core: no I/O in pure functions
4. Keep modules focused — one file per concept

## After implementing
1. Run the full test suite to confirm no regressions
2. Transition to code_review:
   ```
   python3 ~/.automaton/scripts/status.py --transition code_review --task {current_task} --project .
   ```
