The socket used to accept any valid token, so a full REST/actor token could open the
live stream. Now it can require a narrowly-scoped delegated token (aud=iios-message),
so a leaked socket token can't drive privileged REST, and vice-versa.
- MessagePrincipal gains `audience`, surfaced from both verify paths (OIDC aud, and the
app-token `aud` claim).
- message.gateway: when IIOS_REALTIME_AUDIENCE is set, handleConnection accepts only a
token whose aud matches (opt-in, like IIOS_REQUIRE_ATTESTATION; unset = no change).
- spec: verifier surfaces aud; gateway accepts iios-message, rejects iios-core / no-aud
when enforcing, passes through when off.

Enriches the platform PLANE, not the kernel:
- DevOpaPort: the dev OPA stub now evaluates a small policy table (behind the
same opa.decide) — DM capped at 2, add-participant requires member/group-admin,
governed self-join for membership threads. Real OPA swaps in unchanged.
- Dev IdP login (POST /v1/dev/login) issues the same JWT claims a real IdP would.
- PolicyDeniedFilter maps fail-closed denials to HTTP 403.
Generic kernel additions (no chat vocabulary — 'dm'/'group' live only as OPA
policy + an opaque thread attribute):
- MessageService.addParticipant (governed membership by userId), governed
openThread self-join (scoped to threads with a membership attribute),
parentInteractionId on send (reply link), and a generic listThreads.
- REST: GET /v1/threads, POST /v1/threads, POST /v1/threads/:id/participants;
socket add_participant + membership/parentInteractionId. ensureParticipant
gains a role.
Tests: dev-opa.port.spec + message.spec (DM cap / group admin / governed join /
listThreads / reply). smoke-membership.mjs; realtime smokes updated for governed
join. 175 unit tests + all smokes green; kernel free of dm/group literals.

Task T3.1: ActorResolver gains findScope (no-create) + assertOwns(principal,
resourceScopeId) → ForbiddenException on mismatch (KG-02). RouteService.approve/
deny now assertOwns on the decision's binding scope before mutating; listDecisions
is scoped to the caller. Fixes the critical cross-tenant mutation (tenant A could
approve tenant B's route). Also adds IiosScope.cellId + IiosOutboundCommand.scopeId
columns (migration tenant-isolation) + cell assignment on scope create. Test:
another tenant approving → Forbidden, decision unchanged, no scope created, empty list.
