Resolve MR runtime-close-ack-before-release: keep sessions registered while a task-owned close is pending; all DELETE waiters share its result, successful teardown alone removes the entry, and provider errors permit retry. Cancelling HTTP waiters cannot cancel Local provider command teardown.
Add deterministic Local teardown/Runtime active-use tests plus authenticated Backend registry cancellation and same-session retry through actual materializer busy/removal. Focused dependent Server 26 pass, Runtime new 3 and existing close tests pass; root check, fmt, diff, names pass. Full Runtime attempt: 505 pass/63 restore-environment failures; corrected exact 63 pass separately, not a full-suite green claim. Validation logs: target/t805-validation. Base remains 0f82; no T795/T796 import.
Extract the unchanged canonical plan model for typed Runtime snapshots without a Server dependency cycle. Bind Tool consumer identities to persisted Session/call IDs, use the owner-issued context and current publication authorization, and register through FeatureInstallPlan with cooperative shutdown.
Validation so far: root cargo check --locked, portable model 6 tests/doctest, Worker actual Component adapter 7 focused tests, Server plan 9 tests via shared isolation. Full product launch owner/pin lifecycle and Remote/Embedded vertical integration remain a subsequent coherent change.
Bind remote and in-process delivery to authenticated Worker lineage, live installation permission and persisted exact pins. Verify canonical bytes and complete descriptors in a bounded Runtime-only atomic cache; cache hits reauthorize and process-crash staging never becomes visible.
Shares the exact PluginInstallation permission shape published for T-793; no HTTPS or launch/restore integration is included. Depends on the T-465 source ancestry and the shared Host execution identity helper.

Adapt T-778 source 6d15569 and selected T-465 plugin plans on T-803 51f0c7e0. Preserve frozen Workspace107 and append Subject108, current assignee/target checks, recipient-scoped notification recovery and public contract generation. This is a candidate composition, not target adoption.
Exercise public Spawn, real bounded work, other-conversation handling, ordinary Notify and explicit publication to the originating message. Retain stable complete spawn input across acknowledgement loss and retries; verify operation and target revocation without a second result or grant registry.
Compose the published T-803 candidate 51f0c7e019 with T-766 without target adoption. Preserve operation-use versus directional control, notify-only replies, live revocation, and T-766 receipt/provenance boundaries.
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.
