+# issue-reassess evals
+
+Behavioral evals for the `issue-reassess` skill. The campaign-level
+tallies are already covered by the sibling `issue-reassess-stats` suite,
+so these suites anchor on the three places where this skill makes a
+*decision* of its own: whether to re-run a candidate, whether a
+maintainer comment lets it skip reproduction, and which verdicts become
+report headlines.
+
+## Suites (10 cases total)
+
+| Suite | Anchor | Cases | What it covers |
+|---|---|---|---|
+| step-2-resumability | `SKILL.md` → Step 2 (resumability check) | 3 | fresh campaign with auto-generated id, all four artefact states in one pool, everything reusable at the current rev |
+| skip-if-resolvable | `per-issue-flow.md` → 1. Skip-if-resolvable check | 5 | fixed-in-version citation, sibling duplicate, won't-fix by design, no shortcut, injected instruction (adversarial) |
+| headline-extraction | `verdict-aggregation.md` → Headline extraction | 2 | mixed verdicts bucketed into action / closure / hygiene, all-fixed campaign |
+
+## Run
+
+```bash
+# All cases
