inngest

Inngest platform reference for Carbon's background jobs — durable functions, steps, events, flow control, error handling, and local dev, all in the v3 syntax Carbon actually runs (inngest ^3.52 in @carbon/jobs). Use when writing or reviewing Inngest functions, choosing flow-control (concurrency/throttle/rateLimit/debounce/singleton/batch), wiring waitForEvent/sendEvent/invoke, or debugging retries and duplicate work. Do not use for Carbon's DB-event wiring (PGMQ triggers, handler tables) — that is .claude/rules/event-system.md; and do not copy v4 syntax from the internet, see the v3/v4 table here first.
