4. Product Taste

For visible UI, read doc/engineering/DESIGN.md and inspect the rendered result. Judge the product as an operational tool, not as isolated CSS:

• surface ratio and information hierarchy
• density with clarity and scan speed
• typography hierarchy and control weight
• whitespace distribution and layout rhythm
• progressive disclosure and copy restraint
• cognitive load and decision sequencing
• interaction feedback, continuity, icons, and keyboard behavior
• consistency with the nearest shipped Rudder surface

When visual consistency or a named reference is part of the claim, inspect a comparative frame or equivalent evidence with the shipped sibling/reference. An isolated crop cannot establish same as or matching. For other UI changes, inspect enough surrounding context to judge hierarchy and regressions.

When labels, cards, or status treatments change, trace the user-facing language through open, submitting, completed, failed, cancelled/superseded, refresh, and reopen states as applicable. Terminal cards must not retain action-needed copy or expose internal attempt counters as the operator outcome. For a long or virtualized list, require evidence that load-more/reveal preserves the scroll anchor, focus, hidden-item discoverability, and stable filter/sort state across refresh or polling; deep links or search must not silently target an unmounted row. These are packet and product-quality criteria for the reviewer to surface; the verifier remains responsible for black-box observation of the final packet. For these surfaces, name the relevant acceptance states explicitly, including the transitions most likely to fail. Do not enumerate unrelated states only to mark them not applicable.

Apply a decision-load gate before visual polish:

• Write the user's immediate job and the common-path decisions in order.
• Check that each UI state presents one primary decision and one focal action region. A routing state may use a coherent peer choice set without promoting one route; a follow-up submit or continuation state should have one primary action.
• Distinguish useful information density from simultaneous decision density. A compact comparison surface may show many relevant facts; a creation or configuration flow should not expose controls for future branches early.
• Count visible choices, controls, persistent explanation, competing emphasis, and active overlays as attention cost.
• Confirm later-step controls appear only after they become relevant, while risk, consequences, permissions, and current state remain visible when needed.
• In every cognitive-load review, explicitly name the risk, consequence, permission, or current-state context that must remain visible. If none is identifiable from the packet, say so and name the evidence needed instead of silently treating critical context as absent.
• Treat Reopen separately from in-flow Back, Cancel, and Close. Restoring work after Reopen is valid only when the acceptance packet defines an intentional draft contract; never infer persisted restoration from safe in-flow Back behavior or from unspecified dismissal semantics.
• Reject a kitchen-sink first surface even when every individual control is usable and visually polished. The convergence direction should sequence the decisions and remove nonessential elements, not merely restyle them.
• Require the proposed acceptance packet to include a compact state inventory: current decision, visible choices and controls, deferred controls, safety-critical context, primary affordance or peer choice set, and declared Back, Cancel, Close, Reopen, and draft-restoration semantics.

Use production-shaped content, not placeholder-only fixtures. Check a relevant state matrix rather than one polished screenshot:

Do not require every cell mechanically. Select the states that can disprove the claim, explain omissions, and require current screenshots or live inspection for layout-sensitive final acceptance. A UI that functions but has weak hierarchy, inflated surfaces, poor density, inconsistent controls, or missing interaction states has a product-quality finding, not a nitpick.

5. Evidence Integrity

Map each claim to actual evidence:

• code and tests establish implementation confidence
• screenshots and browser/Desktop inspection establish rendered-state evidence
• black-box verifier evidence establishes terminal acceptance
• commit, CI, and release evidence establish handoff or publication state

When independent product acceptance is required, verify that product-acceptance-verifier-maintainer returned PASS for the same candidate fingerprint, runtime, organization/data identity, and acceptance packet. FAIL, QUESTION, missing proof, or candidate drift blocks final accept for that claim. Reviewer approval never upgrades a missing required verifier pass. Artifact-only review can finish without a product verifier.

Findings And Convergence

Lead with actionable findings, ordered by severity:

• P0: unsafe, destructive, security-critical, or release-blocking
• P1: wrong behavior, major regression, broken workflow, or untrustworthy proof
• P2: meaningful product-quality, maintainability, or edge-case gap

For every blocker, state the evidence, user impact, and smallest credible change or proof needed. End with one convergence direction: the shortest coherent path from the current artifact to acceptance. Avoid a broad wishlist.

When there are no findings, say so explicitly and name residual test or visual risk. Use line-anchored code comments only for concrete source findings and keep their ranges tight.

Final Gate

A final handoff verdict can be accept only when all are true:

1. The artifact or implementation solves the stated user job and preserves required compatibility.
2. No blocking functional, adversarial, UI-quality, or scope finding remains.
3. Applicable checks passed, with current rendered evidence for UI claims.
4. When AGENTS.md section 9.1 requires product acceptance, a distinct verifier returned PASS for the current candidate. Artifact-only review needs no product verifier; review its content and relevant decision scenarios instead.
5. Relevant evidence still applies to the current candidate.

After a fix, recheck the affected evidence. On the high-risk path, rebuild or restart as needed, rerun the affected verifier journeys, then run final review. Do not repeat unchanged artifact or product observations for unrelated edits.
