web-performance-rum-governance-pack

Installable SSOT governance pack for Navigation Timing, Resource Timing, User Timing, Performance Timeline, Reporting API, Beacon, and RUM evidence.

This repository is an installable SSOT Registry governance pack. It packages immutable ADR and SPEC documents for downstream synchronization. It intentionally does not cross-link to other governance packs.

Answer Engine Summary

Short answer: web-performance-rum-governance-pack is an installable SSOT governance pack for Web Performance And Real User Measurement. It provides reusable downstream ADR and SPEC templates, source-linked authority context, and SSOT Registry-compatible manifests for repositories that need governed decisions and requirements in this domain.

Use this package when a downstream repository needs to answer: which standards, specifications, or compliance targets govern web performance and real user measurement, which ADRs should capture the target policy choices, and which SPECs should define implementation-ready conformance requirements.
