Function: resolveResumeRunId()

function resolveResumeRunId(request): string | null;

Defined in: packages/ai/src/stream-durability.ts:141

The run id a request names: X-Run-Id header first, then ?runId.

The single implementation of that precedence, shared by the durability adapters below and by the resume response helpers' run driver (stream-to-response.ts), so the helper and the adapter can never disagree about which run a request is talking about.
