Walkthrough

The default CSV path in the metrics collection utility was refactored from a hard-coded relative string to use filepath.Join() for cross-platform path construction. No functional logic or control-flow changes were made.

Changes

Cohort / File(s)	Summary
Path construction refactoring usage-metrics/collect-metrics.go	Updated default CSV path from hard-coded "../../docs/usage-metrics.csv" to filepath.Join("..", "docs", "usage-metrics.csv") for platform-agnostic path handling

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~3 minutes

• Single file, straightforward string-to-filepath.Join replacement
• No logic density or control-flow changes
• Standard cross-platform path handling pattern

Poem

🐰 Paths were tangled, now they're straight,
Cross-platform roads, we celebrate!
From strings to joins, a hop and a bound,
Better paths on every ground. ✨
