Entry condition check

Before asking anything, verify:

1. Discovery artefact exists at artefacts/[feature]/discovery.md - status "Approved"
2. Benefit-metric artefact exists at artefacts/[feature]/benefit-metric.md
3. Benefit-metric artefact contains at least one metric with a defined target

Also check for reference materials at artefacts/[feature]/reference/. If present, scan for technical designs, scoping documents, or programme-level constraints that should shape story decomposition and are not yet reflected in the discovery or benefit-metric artefacts. Surface any that are relevant before choosing a slicing strategy.

If not met (entry condition):
