PR preview + contract checklist

🔍 Live preview: https://cumulativewebinc.github.io/ultimate/pr-previews/15/

Production: https://cumulativewebinc.github.io/ultimate

	check	detail
✅	agent-card	./.well-known/agent-card.json: valid, name='Project Ultimate'
✅	schema-versions	SCHEMA-VERSIONS.json: all registered documents match
✅	content-json	./content.json: valid JSON
✅	changelog	CHANGELOG.md: present
✅	api-version-pin	no API-VERSION pin in this repo — skipped

Contract gate result: success — the build fails when the agent-card is missing/invalid, the SCHEMA-VERSIONS contract breaks, content.json is invalid, CHANGELOG.md is missing, or the API-VERSION pin mismatches.
