Import Service CPU Spike Investigation (May 9, 2026)

Summary

On May 9, import-prod avg request duration jumped from ~10s to 3,240s (54 minutes), autoscaling kicked in from 2 to 7 tasks, and 500 errors spiked 20x. No code was deployed to the import service. The root cause was a Transloadit outage that exposed the fact that the import service has no enforceable request-level timeout anywhere in the stack.

Agentic import was ruled out — its CPU was ~0.5%, and import-prod request volume was flat across the incident window.

Why the slow ramp didn't catch the flux-2-klein outage

The problem

On 2026-04-21, Black Forest Labs' API endpoint api.bfl.ai/v1/flux-2-klein-9b-private started returning 404 Not Found on every request. This has been going on for 24+ hours. Every image generation request that targets flux-2-klein fails immediately (~49ms), the ImageModelFallback catches the error, and the system falls back to flux-1-quick or qwen-image-fast.

The fallback chain is working, so users still get images. But we're making ~300-500 wasted API calls per hour (spiking to 18k+ during peak) to an endpoint that's been dead for over a day. No automated system detected or responded to this.

What we wanted slow ramp to do

PR #18856 Review Notes

Follow-up items

1. `saveFn` as constructor param

BuddyAgent takes a saveFn callback and wires debounce + flush-chaining inside its constructor:

// BuddyAgent.ts:91,103-121

Unprocessed Card HTML Emitter

What changed

Added a typed EventEmitter to the deck generation pipeline so we can tap into raw card HTML before post-processing (layout formatting, image injection, etc.).

New file: `packages/server/src/common/event-emitter.ts`

Generic, typesafe EventEmitter<EventPayloads> class. Supports:

Typed on/off/emit keyed by an event map

Interview Laptop Provisioning

Problem

Laptops are unreliable for interviews — passwords missing, software not installed, candidate artifacts visible from previous interviews, no clear ownership, interviewers scrambling to use personal machines.

Architecture

Split responsibility between Kandji (IT-managed, slow-changing) and a git repo (eng-managed, fast-changing).

PR #19026 — Suggested simplification

The polymorphism win (no any casts, cleaner component API) can be achieved without the abstract class hierarchy. Here's the alternative.

Types — plain objects, no classes

Keep the original discriminated union types unchanged:
