# Task: High-effort fixture

## Intent

Test fixture for v5.1.1 runtime resolver tests — all 4 phases at the
high effort tier with explicit opus model overrides. Mirrors the
production-grade premium-profile scenario.

## Goal

Resolver returns `{effort: 'high', model: 'opus'}` for each of the 4
PHASE_SIGNAL_PHASES.

## Success Criteria

- Validator passes.
- resolvePhaseSignal(fm, phase).effort === 'high' for all 4 phases.
- resolvePhaseSignal(fm, phase).model === 'opus' for all 4 phases.
