review: confident-wrong pass — judge the change as a whole, not just its lines

+3. **First, judge the change as a whole — the confident-wrong pass; this is where the dangerous PRs hide.**
+   Before any line-level review, step back and attack the CHANGE ITSELF, not its code. The PR that slips past
+   every check is the polished, confident one built on the wrong idea — there's no single bad line for line
+   review to catch, so a clean, tidy surface buys it NO benefit of the doubt; be MORE skeptical of confident
+   code, not less. Ask:
+   - **Does it need to exist, and does it do what it claims?** Is the premise real, or an unproven theory the
+     author talked themselves into? Does the diff actually change the behavior the PR describes, or is it a
+     confident no-op / a change at the wrong layer? Verify the real effect against the checkout — don't take
+     the description's word for it.
+   - **Is this the simplest change at the right owner**, or materially bigger than the problem? An invented
+     fallback / retry / polling / UI path, a new abstraction or config seam, special-case proliferation where
+     one default would do. If a competent engineer would write a third of this, the rest is slop.
+   - **Is the complexity earned by a real, present need**, or speculative ("might need it later")?
+   If the whole approach is overbuilt, built on a wrong premise, or a hollow no-op, that is your FIRST and
+   highest finding — a 🔴 `overbuilt` / `wrong-premise` / `confident-noop`, anchored to the most representative
+   changed line. Say plainly what the minimal version is and what to cut. This finding needs NO corpus-primitive
+   citation and is NOT subject to the suppression rule below — it's judged against the bar (the smallest change
+   that solves the real problem). Catching the confident slop the checks waved through is the most valuable
+   thing you do.
+4. Review every changed code file (skip lockfiles, generated/snapshot files, pure deletions). Catch BOTH
    kinds from the rubric — the "just wrong" (bug / type-lie / dead-code / footgun) and the "taste / reuse"
    (reinvents-primitive / slop). "Slop" is code RELATIVE to the simpler or already-existing way: does it
    reinvent a corpus primitive, or is it bigger / more abstract / more speculative than the corpus pattern for
    the same job? When you cite a fix, name the actual corpus file/primitive it should use.

 # Anti-slop rubric — what counts as slop (the taste, alongside `CORPUS.md`)

+## Confident-wrong — the whole change, judged against the simplest version (NO corpus citation needed)
+The slop that passes every check: it compiles, it's tidy, it reads confidently — and it's still the wrong
+change. Flag these on the CHANGE AS A WHOLE, on confidence, even when no single line is locally "wrong" and you
+can't cite a corpus primitive. Judge against the bar: the smallest change that solves the REAL problem.
+- `kind: wrong-premise` — solves a problem that isn't real, or rests on an unproven theory; the premise behind
+  the diff doesn't hold. The fix is "don't do this / prove the premise first," not a code tweak.
+- `kind: overbuilt` — materially bigger than the problem: an invented fallback / retry / polling path,
+  speculative UI, a new layer or abstraction, or special-case proliferation where one default suffices. The fix
+  is the smaller version — name what to cut.
+- `kind: confident-noop` — confidently claims a fix but doesn't change the real behavior (a no-op, or a change
+  at the wrong layer). Verify the actual effect against the checkout.
 
 ## Just wrong — flag regardless of the corpus
 - `kind: bug` — correctness bugs; off-by-one; broken null/empty handling; wrong condition.
