runner::batches() reports items per second at 1, 4 and 8 threads. bench --gate runs a fixed workload under cachegrind (scripts/gate.py, make bench-gate); a rise of more than 10% over bench/gate_baseline.txt fails in CI.

Phase 3 steps 3 and 7 of PLAN.md: benchmarks for batches, and the CI performance gate.
runner::batches()in the sharedbench/bench.hppreports items per second at 1, 4 and 8 threads, andbench/bench.cppcalls it for the library's batch getter.bench --gateruns a fixed workload (one load, 1,000 calls of every getter, one batch of 1,000) with no timing loops.make bench-gateruns it under Valgrind's cachegrind (scripts/gate.py) and compares the instructions executed withbench/gate_baseline.txt; a rise of more than 10% fails. Instruction counts are stable from run to run, unlike wall time on a shared runner. Wall time and memory stay a report.scripts/gate.py build/bench_gate --updatethere and commit the new baseline.🤖 Generated with Claude Code
