Changelog 2026-03-07 (Roadmap 4: Weekly Metric Ownership Regression Guardrail)

Article content

What changed

• Added explicit metric ownership metadata on /pages/projects/ dashboard metrics (data-metric-label + data-metric-owner) in both Health and State Machine modules.
• Added scripts/validate-metric-ownership.mjs to enforce overlap rules:
  • every labeled metric must declare an owner
  • overlapping labels must have distinct owners
• Wired the guardrail into CI and added a weekly scheduled CI run.

Why this matters

Roadmap 4 required a regression check to prevent Health and State Machine surfaces from drifting back into redundant metric semantics. This guardrail makes ownership drift a failing signal instead of a latent UX ambiguity.
