A newly connected account showed no videos until the next 2h scheduled pass — the gap that made onboarding look broken (a second user connected, saw nothing, read as failure). The connect callback now fires an out-of-band discovery pass for the connecting user, so videos appear promptly. Concurrency: scheduled and connect-triggered passes share one lock (serialize), preserving the single-fetcher invariant (ADR-018). A trigger interleaves between the scheduler's per-user passes rather than fetching concurrently or waiting for a whole pass. The trigger runs on the server ctx (survives the redirect) and is non-blocking for the request goroutine. Scope: connect-trigger only. The optional login-refresh / "Discover now" button from #6 are intentionally not built — an unconditional login hook risks 429 storms (per the ticket's own recommendation); defer until wanted. TDD: TestCallbackTriggersDiscovery, TestSerializeRunsOneAtATime, TestDiscoveryTriggerEnqueueRunsUser; new BDD scenario mapped.
