Validate management additions in the existing CAS/replay transaction while retaining exact legacy entries in their original lane. Expose read-only account capability and test real saved-policy authorization, conflicts, replay and deletion fences.
Protect attributed originals before the first public commit; distinguish pending Session material from missing committed sources. Gate removal admission by the Journal Feature and resolve Subject ownership from durable singleton authority. Resume explicit erasure through signed delete transport and proof-bound purge plans without creating a Journal Job or archive.
Validation: changed-crate suites, root check, doc/fmt/diff/naming checks, Server/Runtime builds and worker_environment isolation suite passed. Public standalone scripted dialog connects Host, automatic Job, sequential tools and drain while dialog continues. Backend public embedded WorkerRemove tests connect removal forwarding, durable Jobs, retention, Runtime and SQLite; Session/attribution/profile fixture setup bypasses creation/auth routes. Runtime signed generated-client tests separately exercise request authentication.
Limits: real-model semantic acceptance condition 6 remains unevaluated without a new explicit model/credential/budget grant. Conditions 1/7/8/11 do not have complete product E2E coverage: worker_environment only verifies isolated startup/connection/cleanup. Compaction tests connect local hooks/reader/store rather than the full public dialog-to-Journal chain. Erasure racing a previously prepared Archive removal plan fails closed with conflict; automatic stale-plan replacement is not implemented.
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.
