Config, temp files, and shutdown

Load and validate environment/config against any Standard Schema validator (Zod/Valibot/ArkType/...) with a fail-fast, all-errors-at-once report. Validator-agnostic, zero own deps.

Self-cleaning temp files and directories , scope-bound via `using`, swept on crash and signal, zero dependencies.

Ordered, timeboxed graceful shutdown for Node , register named async hooks, drain them LIFO on SIGTERM with per-hook timeouts and a hard deadline.

Adapters that turn callbacks, event listeners, timers, and AbortControllers into `using`-ready disposables. Adopt Explicit Resource Management with the APIs you already have. Zero deps.
