Recommended action: Read the target tuple: if the platform/libc/ABI has no prebuild, allow the package's install script to build (toolchain needed) or pick a supported base image/Node version; for bundlers mark the package external and ship node_modules; <NAME>_PREBUILD env var

Proposed fix: [Selenium/Chrome in Docker] 'session not created: ... DevToolsActivePort file doesn't exist' — Chrome crashes at start (small /dev/shm, or /dev/shm without exec on Docker Desktop WSL2)

Recommended action: Run browser containers with --shm-size=2g (docker-selenium guidance); capture Chrome's own stderr/log to find the real crash reason; on Docker Desktop WSL2 check /dev/shm mount permissions; pin full image tags. Option: Give Chrome enough shared memory [evidenc

Recommended action: Call await pyodide.loadPackagesFromImports(code) or micropip.install/loadPackage before running; avoid removed stdlib modules (use pure-Python alternatives). Option: Call await pyodide.loadPackagesFromImports(code) or micropip.install/loadPackage before runnin

Proposed fix: [RabbitMQ] long-running jobs (Celery/LLM agent tasks) kill the channel: PRECONDITION_FAILED 'Consumer ... has timed out waiting for a consumer acknowledgement of a delivery ... Timeout u

Recommended action: Ack earlier (and track progress elsewhere), reduce prefetch so messages don't wait unacked in the client, or raise consumer_timeout per node (rabbitmq.conf) or per queue (consumer-timeout policy / x-consumer-timeout argument, 3.12+) to cover the longest task.
