## bootstrap — make scripts executable and create results/ (safe to re-run)
bootstrap:
	chmod +x scripts/*.sh workloads/probe/probe.sh
	mkdir -p results

## run-local — run the benchmark step sequence on THIS machine (smoke-test /
## local baseline). Emits ./results.jsonl, mirroring the CI step order.

## collect — fold a results.jsonl into the results tree:
##   make collect PLATFORM=github RUN_ID=<id> SRC=/path/to/results.jsonl
collect:
	@test -n "$(SRC)" || { echo "usage: make collect PLATFORM=<p> RUN_ID=<id> SRC=<results.jsonl>"; exit 2; }
	scripts/collect.sh "$(PLATFORM)" "$(RUN_ID)" "$(SRC)"

## compare — median/p95 table from everything collected so far
compare:
	python3 scripts/compare.py

## clean — drop local run outputs (not the collected results/ tree)
clean:
	rm -f results.jsonl
	rm -rf workloads/rust-build/target
