I completed Worker CPU/disk benchmarks by adding a reproducible benchmark harness at src/test/java/org/example/videoclips/perf/WorkerBenchmarkHarness.java:1 and checking in the resulting baseline at docs/worker-cpu-disk-
benchmark-baseline.md:1. The harness measures synchronous worker wall time, current-thread CPU time, clip count, and local/uploaded output bytes for FAST and EXACT stub-processing scenarios, and writes the generated report to
target/benchmarks/worker-cpu-disk-benchmark.md.
The plan now marks that item complete in docs/video-clipping-service-implementation-plan.md:711. Verification also stayed green: mvn -q -Dtest=WorkerBenchmarkHarness test passed, and mvn -q test passed with the default suite
plus the benchmark harness.
