Domain extraction
Activation contract: when this Skill is directly visible as Core, load the
complete SKILL.md in one standalone read before task work; when a verified
activation result already supplied this exact complete content, do not read
SKILL.md again.
Before producing the deliverable, read references/domain-schema.md from this
Skill package and follow its schema exactly. Extract only terms and
relationships supported by the supplied notes; do not invent definitions,
owners, aliases, or dependencies. Write valid UTF-8 JSON to the requested
output path and preserve the reference ordering rules.
