Profile verification

• Marks bar/line/area/point/pie/donut bind explicit selected records. Numeric values must be finite numbers; numeric strings are not coerced.
• x is category/number/date; point requires numeric x, bar/pie/donut category. Line/area may use category, number or UTC date.
• Zero-baseline and arc share rules remain mark-specific; unit declarations must agree with supplied record units.
• aggregate none/sum/count/min/max/mean is available only on supported bar/arc/top-k paths, with contributor IDs preserved; count has no physical unit.
• Explicit empty records is legal for bar/line/area/point; filtering a nonempty selection to nothing is an error. Missing error/skip is explicit.
• Specialization mark sankey uses channels: x y target. Positive finite flows between explicit source/target names; DAG columns derive from pure sources. Duplicate source/target pairs remain separate ribbons stacked in declaration order; thickness encodes value. No series or implicit accounting conservation claim.

Profile defaults

Explicit file settings override eligible CSS, then these profile defaults and the common standard apply. Unspecified semantic facts remain unspecified.
