Phoenix OTel Development

OpenTelemetry registration and provider lifecycle layer for Phoenix. Single source of truth for OTel configuration — other Phoenix packages delegate here rather than importing OTel packages directly.

Read existing code in the directory you're working in before writing new code.

Rule Files

rules/global-provider-lifecycle.md Global provider attachment, detachment, snapshot/restore, mount stack

Build and Test

cd js/
