Investigate

Source of truth for evidence-based hunch verification.

Find and verdict only — locate the issue or settle the claim with citable primary-source evidence. Do not propose code edits, diffs, or “change X to Y” in the verdict or evidence sections unless the user explicitly asked to implement, repro, or fix. Route fixes in What to do next (e.g. diagnose / tdd) — do not ship the fix in this pass.

After the verdict, What to do next prefers hub diagnose / tdd when installed; otherwise consumer testing / debug or project AGENTS.md. If the user explicitly asks to implement, repro, or fix after the verdict, follow that request (or the named skill).

Primary-source-first after the target is clear: read the actual code, source document, or data.

Read references/research-basis.md when calibrating a move or making a research claim. Do not load by habit.
