bug-hunting

Broad defect sweep of the NEREIDS workspace ahead of a release / paper. RUN FROM THE MAIN REPO ROOT (not a .claude/worktrees/ session) so SAMMY primary sources resolve and subagents are not sandboxed away from them. Complements /review-pipeline (which is per-PR-diff + fix + merge gates); this workflow is whole-crate DETECTION only — it finds and locates defects, cross-verifies them across two LLM families, and reports. It does NOT fix anything.

Pre-release audit on signal-heavy domains (imaging, DSP, physics) where real bugs justify multi-agent search cost.
