## Fontes de Dados

### 1. Git History (fonte primaria)
```bash
# Commits por dia/semana
git log --oneline --since="30 days ago" --format="%ad" --date=short | sort | uniq -c

# Commits por autor
git shortlog -sn --since="30 days ago"

# Arquivos mais modificados (hotspots)
git log --since="30 days ago" --pretty=format: --name-only | sort | uniq -c | sort -rn | head -20

# Churn (linhas adicionadas/removidas)
git log --since="30 days ago" --numstat --format="" | awk '{add+=$1; del+=$2} END {print "+" add " -" del}'

# Commits por tipo (conventional commits)
git log --oneline --since="30 days ago" | grep -oP "^[a-f0-9]+ \K(feat|fix|refactor|docs|test|chore)" | sort | uniq -c | sort -rn

2. Codebase Metrics

# Total de arquivos e linhas por tipo
find src -name "*.ts" -o -name "*.tsx" | wc -l
find src -name "*.ts" -o -name "*.tsx" | xargs wc -l | tail -1

# Cobertura de testes (ratio test files / source files)
TEST_FILES=$(find . -name "*.test.*" -o -name "*.spec.*" | wc -l)
SRC_FILES=$(find src -name "*.ts" -o -name "*.tsx" | wc -l)

# TypeScript strictness (any count)
grep -r "any" --include="*.ts" --include="*.tsx" src/ | grep -v "node_modules" | wc -l

# TODO/FIXME/HACK count
grep -rn "TODO\|FIXME\|HACK\|XXX" --include="*.ts" --include="*.tsx" src/ | wc -l
