Why: Account disable could be followed by late Backend business writes, API key creation could implicitly create users, account bootstrap locks could invert, and directory cursors were process-local or leaked out-of-scope changes.
Evidence: Local go test ./... and isolated PostgreSQL package suites passed on the staged candidate; exact committed-head SELF replay and stage 6 human review remain pending.
Impact: Adds final account transactions and external-effect checks across HTTP, Host, Bus and run manager; tightens API key issuance and persists versioned cursor signing. Delegated RDM rename still needs the separately proposed real-operator contract, so A1 and stage 6 are not complete.

Why: GET /api/commands/audit leaked every tenant's audit rows (command ids, entrances, conversation ids, param digests) to any authenticated user; owner was never recorded nor filtered.
Evidence: Red run at a7cc69b FAIL (alice sees bob's row); after fix go test ./... 32/32 packages ok, including TestCommandAuditOwnerScoping and the v18 backfill test (rows recorded on the task card).
Impact: v18 migration adds command_audit.owner with actor-based backfill (empty-actor rows stay invisible via API, kept in-table); AppendAudit/ListAudits gain owner params; cmdbus port and fakes updated; handler passes authenticated owner. No public extension surface change.
Refs: Task card R1; U0 proposal section 5 C7 finding.
Why: GET /api/commands/audit returns every tenant's audit rows; the regression test pins the desired owner-scoped behavior before the fix.
Evidence: go test ./internal/server -run TestCommandAuditOwnerScoping FAIL (owner alice sees bob's row; output recorded on the task card).
Impact: Test only; suite red on this commit by design.
