gsxdsm 6a81871781 chore: refresh weekly test-velocity baseline (2026-W28) — confirm gate regression resolved
Gate wall-time back down to 8.8s (was 36.3s this morning, pre-FN-7667/7669 fix landing). Cycle 2026-W28 re-measured post-fix.

# 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.
## Latest baseline
- Cycle: **2026-W28**
- Captured at: **2026-07-08T18:17:42.464Z**
- Timing snapshot: `scripts/test-timings.json` captured at **2026-06-27T05:41:42.568Z**
- Quarantine ledger: `scripts/lib/test-quarantine.json`

| Boot smoke wall-time (`pnpm smoke:boot`) | 17.6s | -7.7s |
| Changed-only test wall-time (`pnpm test`) | 1m 01s | +18.0s |
| Quarantine / flake count | 1 | 0 |
| Deletion-due quarantines | 0 | n/a |
## Measurement failures
- None recorded.
## Timing snapshot notes
- No stale or missing timing metadata detected in the rendered slowest-file rows.

## Post to #leads
```text
FN-6612 weekly test velocity: gate 8.8s (-27.5s), boot smoke 17.6s (-7.7s), pnpm test 1m 01s (+18.0s), quarantine ledger 1 (0). Slowest file: packages/dashboard/src/__tests__/insights-routes.test.ts at 26.5s. Deletion-due quarantines: 0.
```
## How to refresh
```bash
pnpm test:velocity -- --measure --write-report
```
In measure mode, the script runs a non-measured `pnpm build` preflight before timing `pnpm test:gate`, `pnpm smoke:boot`, or `pnpm test`. The preflight time is setup only and is excluded from lane metrics; if it fails, the Measurement failures section records `Build preflight (pnpm build)` as the reason. Use `--skip-build-preflight` only when the workspace is already built by CI.
Report-only regeneration is cheap and does not run any suite:
```bash
pnpm test:velocity
```
