feat: criterion benchmarks for scheduling solver + codegen (#137)#143
Conversation
Adds `benches/` to spar-solver and spar-codegen with criterion harnesses plus CI plumbing to gate compilation and collect nightly baselines. spar-solver groups: - small (<=8 tasks, RM-feasible utilization) - medium (<=64 tasks, representative avionics workload) - large (<=256 tasks, sample_size=10 to keep runtime sane) - worst_case (utilization ~0.95 schedulability boundary) spar-codegen group: schedule emission for 64-task workload. CI: - `bench-smoke` in ci.yml: `cargo bench --no-run` on PRs (compile gate) - `bench-nightly.yml`: cron daily 03:30 UTC, saves baseline, uploads target/criterion/ Traceability in `artifacts/verification.yaml`: bench entries linked to existing REQ-SOLVER-* and REQ-CODEGEN-* requirements. Closes #137. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
