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.
Normal merge of develop@b0bce50b retains T-692 state hierarchy, diagnostics disclosures, ready-empty and candidate-only regressions alongside T-693 behavior/CAS/route fences. ResidentContext load and refresh retain the five-second timeout from 685b8aa6, with a seven-request regression.
Validation: root cargo check; full worker(serial), session-store, workspace-server and server-api(typescript) suites; frontend check with zero diagnostics; 464 Web tests and 171 component tests (19 Memory); production Memory browser-shell test/build; fmt/diff/OpenAPI checks.
