⚠️ Potential issue | 🟠 Major | 🏗️ Heavy lift

The algorithm does not measure actual repository health.

The current implementation uses raw totals (totalIssues + totalPrs) regardless of state, which produces misleading results. A repository with 1000 open, unresolved issues would score "Excellent" (100/100), but that indicates poor health, not good health. Additionally, cumulative totals from the GitHub search API don't reflect current activity or maintenance quality.

Issue #719 requires analyzing:

  • Issue resolution rate (closed/total)
  • Pull request merge rate
  • Open vs closed issues ratio
  • Contributor activity trends
  • Repository update frequency

Consider refactoring to compute ratios and rates instead of raw counts. For example:

  • issueResolutionRate = closedIssues / totalIssues
  • openIssueRatio = openIssues / totalIssues
  • Weight and combine these metrics into a composite score

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In `@src/components/Dashboard.tsx` around lines 76 - 79, The current healthScore
calculation using totalContributions is misleading; replace it with a composite
score computed from ratios (not raw counts). Compute metrics like
issueResolutionRate = closedIssues / totalIssues, openIssueRatio = openIssues /
totalIssues, prMergeRate = mergedPrs / totalPrs, contributorActivity =
recentContributorCount / totalContributors, and recencyScore from
lastCommitDate; then weight and combine these into a single healthScore (e.g.,
weighted sum normalized to 0–100) and update the code that references
healthScore and totalContributions so that healthScore uses these new ratio
variables instead of Math.round((totalContributions / 50) * 100). Ensure you
handle divide-by-zero (fallbacks when totalIssues or totalPrs are 0) and update
any UI labels that describe the metric.
