Task 7.3: AiJobService runs scoped/purposed AI jobs that only propose — fails
closed via OPA (KG-03), degrades on budget (AiBudgetGuard sums costUnits, KG-12),
then persists job+modelRun+artifact(PROPOSED)+claims+evidence with full
provenance. CLASSIFY also proposes IiosModerationFlag(proposedBy:'AI'). accept/
reject record human feedback + emit events. Idempotent per job key. INFERENCE_PORT
binds LocalDeterministicInference for nest start; specs inject testkit FakeInference.
8 tests: classify/summarize/extract, fail-closed, budget-degrade, idempotent, accept.
