# Test velocity baseline

> Weekly FN-6612 signal-per-second baseline. Measure and report feedback-loop velocity; do **not** add slow tests or wire this report into blocking PR checks. The merge gate remains the existing thin Lint, Typecheck, Build, and Gate path.

## Post to #leads

```text
FN-6612 weekly test velocity: gate 5.4s (-779ms), boot smoke 18.1s (-123ms), pnpm test 7.2s (-500ms), quarantine ledger 0 (-2). Slowest file: packages/engine/src/__tests__/reliability-interactions/shared-branch-group-lifecycle.test.ts at 13.9s. Deletion-due quarantines: 0.
```

## How to refresh

```bash
pnpm test:velocity -- --measure --write-report
```

Report-only regeneration is cheap and does not run any suite:

```bash
pnpm test:velocity
```
