- Verification: the inventory test requires all 70 files, exact family counts,
unique local mappings, and reports synthetic source changes, additions, and
removals. The offline command verifies all five spike mappings.
- Follow-up observed in nightly run 34598495700: the shared Recharts reference
omitted chart accessible names and reduced distinct radial and custom-label
examples to generic family defaults. The pinned radial-shape source has one
Safari datum, not the five required by generated case metadata. Restore the
pinned data, paint, label placement, and radial background configuration;
name each reference SVG through its chart props; and correct the generator's
single-datum expectation. DOM regressions cover the reference names through
updates, radial data counts and paints, and both custom bar label sets. The
complete standard shard 4/8 passes all 24 cases, including the nine former
failures, with the original geometry, paint, and accessibility gates intact.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the relative label positions. The chart-bar-label-custom adapter assigns insideLeft to month labels and right to desktop-value labels. Each rendered .recharts-label is an SVG text element with an x coordinate, so assert that each month label is left of its matching value label. This conformance test is the repository’s regression check for this visual contract.

In `@benchmarks/conformance/shared/shadcn-reference-accessibility.test.ts` around
lines 58 - 63, Extend the assertions around the label collection in the
conformance test to verify relative SVG x-coordinate positions: for each month
label, assert its x position is less than that of the matching desktop-value
label. Use the rendered .recharts-label elements and preserve the existing count
and text-content assertions.
