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: the admin zone could not host plugin-declared partitions - KTD4
requires the RDM audit partition to be reachable by RDM domain admins and
base superadmins without hardcoding RDM into the base AdminZone.
Evidence: go test ./internal/app ./internal/server ./pkg/extension green
incl. new admin-zone recording/endpoint tests; surface snapshot test
green after surface.txt update; CI (Dev composite) is authoritative.
Impact: extension surface 2.8.0 -> 2.9.0 (Registry.AddAdminZone +
AdminZoneSpec, fail-closed on invalid specs); applyCompiled records
declarations into the plugin summary; new authenticated GET
/api/admin-zone/sections returns the flattened, ordered declaration list.
Entry visibility stays metadata-only - data capability remains enforced
by each section's own command surface (fail-closed).
