Require measurements to be an array before saving the baseline.
The current check accepts any value with a non-zero length. For example, a string or { "length": 1 } passes and is copied into perf-data. Validate the report schema before treating it as completed measurements.
Proposed fix
- MEASUREMENT_COUNT=$(node -e "const report=require('./test-results/perf-metrics.json'); process.stdout.write(String(report.measurements?.length ?? 0))")
+ MEASUREMENT_COUNT=$(node -e "
+ const report = require('./test-results/perf-metrics.json')
+ if (!Array.isArray(report.measurements)) {
+ console.error('perf-metrics.json measurements must be an array')
+ process.exit(1)
+ }
+ process.stdout.write(String(report.measurements.length))

Normalize grep filters before accessing .source.
Playwright types grep and grepInvert as RegExp | RegExp[]. Normalize each filter before reading .source; otherwise the scripts typecheck fails.

Test workflow outcomes instead of command text.
These assertions only check for YAML fragments. They do not verify that a failed benchmark with completed metrics saves a baseline, that cancellation skips the save, or that missing and empty reports fail the job.
Extract the report-validation decision into a testable command or helper. Test valid measurements, partial benchmark failure, cancellation, missing reports, and empty measurements. As per path instructions, “Performance-report tests should verify observable behavior rather than implementation details or mock calls” and must cover those cases.
