/**
 * routes/attribution-ingest.ts, the runtime-bus → cost-attribution ingest.
 *
 * LLM usage lands from LLM_RESPONSE_RECEIVED turn events (with agent /
 * tool / hook / MCP origin dimensions and quota-window snapshots from
 * rate-limit headers). Metered VOICE spend rides the same ledger from
 * PROVIDER_VOICE_USAGE events: the billable unit count lands on inputTokens
 * under a voice-scoped model key (e.g. `elevenlabs:voice-tts:characters`),
 * honestly UNPRICED until the one-key manual price (pricing.modelPrices)
 * names the USD per 1M units. Local voice engines never emit the event,
 * no billing dimension at all, never a fake $0.00.
