# Performance evidence contract
|
||||
|
||||
Performance evidence is deliberately split by measurement context:
|
||||
|
||||
- `bundle.json` records production build output and enforces initial JavaScript
|
||||
at 200 KiB gzip and every lazy chunk at 120 KiB gzip.
|
||||
- `lab.json` records Chromium/runner/viewport/network/CPU/cache/build context and
|
||||
enforces LCP 2.5 s, CLS 0.10, and the named route interaction at 200 ms.
|
||||
- `field-web-vitals.json` records consent-filtered, route-ID aggregated,
|
||||
release-specific production samples over 28 days and evaluates p75 LCP, CLS,
|
||||
and INP against 2.5 s, 0.10, and 200 ms.
|
||||
|
||||
The field minimum eligible-sample threshold is intentionally unresolved until
|
||||
a privacy-approved telemetry baseline exists. Therefore the field command
|
||||
fails closed with `FAIL_UNVERIFIED` when run against the example input. Provide
|
||||
`FIELD_WEB_VITALS_INPUT` and a reviewed `MIN_ELIGIBLE_SAMPLES` only after that
|
||||
decision is recorded.
