# Scale plan for annotation round-trip (51 steps)

This fixture is used by tests/integration/annotation-roundtrip.test.mjs to verify SC3 (>=50 steps + >=100 anchors) without breaking the parser at scale.

## Context

Each step is a sentinel-only step with a valid manifest. The plan validates against plan-validator --strict.
