# Task: Low-effort fixture

## Intent

Test fixture for v5.1.1 runtime resolver tests — all 4 phases at the lowest
effort tier with explicit sonnet model overrides.

## Goal

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

## Success Criteria

- Validator passes.
- resolvePhaseSignal(fm, phase) is non-null for all 4 phases.
