Validate exact Component interfaces and static Tool/DCDL schemas without guest execution. Share canonical archive packing and independent package/artifact verification; build real pure and HTTPS PDK fixtures and retire v1/Service authoring stubs.
Use content digests, key fingerprints, binding and trust identities, immutable mutation receipts, and observation tokens instead of state-update ordinals across API, storage, Runtime, and Web contracts.
Preserve historical replay and secret material through frozen migrations; preflight uncertain removals before cutover, resume provisioning receipts, validate encrypted migration candidates, and align fresh/upgraded schemas. Include reviewed regression fixes, generated artifacts, and validation evidence.
