No baseline found. Capturing initial baseline...

Error message

No baseline found. Capturing initial baseline...

What it means

Bootstrap path in PerformanceBaseline.compare(): no baseline data exists yet, so compare() captures the current metrics as the initial baseline and returns an empty comparison array. First-run seeding, not a regression.

Solutions

1. Commit the captured initial performance baseline so future runs can compare against it.
2. Verify the baseline file path is correct and restore it from version control if it was deleted.
3. Re-run the baseline capture on representative hardware before trusting comparisons.

When it happens

Trigger: Performance regression suite runs without an existing baseline file (first run on a machine, cleaned artifacts, or new benchmark); current timings are captured as the reference baseline.

Common situations: See trigger scenarios.
