Coverage Gap Prioritization Guide

Use this rubric for each uncovered area.

Score = (Criticality × 2) + CoverageDebt + (Volatility × 0.5)

• Criticality:

  • 5: authz/authn, data-loss, payment/consistency path
  • 4: state mutation, cache invalidation, scheduling
  • 3: error handling + fallbacks in user-visible flows
  • 2: parsing/format conversion paths
  • 1: logging-only or low-impact utilities

• CoverageDebt:

  • 0: 0–5 uncovered lines
  • 1: 6–20 uncovered lines
  • 2: 21–40 uncovered lines
  • 3: 41+ uncovered lines

• Volatility:

  • 1: stable legacy code with few recent edits
  • 2: changed in last 2 releases
  • 3: touched in last 30 days or currently in active PR

Sort by score descending, then by business impact.
