ADR 0010 — Coverage scope focuses on modularized, testable code

Decision

• Limit coverage measurement to:
  • src/**/* (extracted modules we are actively testing), and
  • scripts/init-*.mjs (small DOM bridges with DOM tests).
• Exclude legacy monolith (script.js) and infra scripts (audit/serve/ci-check, etc.).
• Keep global thresholds (L70 / B70 / F50 / S70) unchanged.

Rationale

• Totals were dominated by the legacy script.js (0% by design — not imported in tests).
• This change makes our coverage actionable, reflecting the parts we’re migrating and testing.

Consequences

• CI passes/fails based on coverage of the extracted modules and bridges — the real “units under test” for now.
• As we extract more from the monolith into src/, they will automatically fall under coverage.
