Use the current Workspace signing identity for each request and remove binding key copies and verification handshake gates. Preserve explicit trust and revocation, migrate historical evidence, and align Runtime settings and connection tests. Retain request scope and durable replay protection with regression coverage.
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.
