  "$comment": "SINGLE SOURCE OF VERSION TRUTH for the Build-with-Universal-Manifest Agent Integration Kit (WO-0530). Every version-specific link in the guide and the skill resolves through this file. Bumping a spec version = editing ONLY this file; the guide, skill, PDF, and site page re-point automatically on the next assemble. Do NOT hard-code version strings (v0.3, v0.4, ...) in guide/skill BODY content — reference these keys instead. Adopts the immutable-path + latest-alias policy from docs/PUBLISHING-AND-VERSIONING.md.",
  "$bumpProcedure": "When a version graduates to stable: (1) ensure its entry under .versions[<id>] has the SAME full field set as the current stable entry (readme, conformanceDoc, context, contextUriInManifest, signatureProfile, etc.) — the guide references these and assemble.sh fails loud on any missing field; (2) set .stable (and/or .preview) to the new id; (3) update .stabilityTiers; (4) re-run agent-kit/assemble.sh. The preview entry below is intentionally partial (preview spec ships schema first) and must be completed before it can become stable.",
