Validation codes give authors stable names for common failure classes. Use the code to decide whether to fix, accept, suppress, or investigate further.

Where this fits

• Faster Motion docs map shows the full documentation structure.
• Faster Motion documentation overview explains the high-level surfaces and reading order.
• Debugging and preflight explains validation before publish.

Common blocker classes

• Missing selectors: a graph node targets an element that does not exist in the loaded page.
• Invalid selectors: the selector string cannot be parsed by the browser.
• Dead wires: a connection references an input or output port that does not exist on the source or target node.
• Bad runway: a scroll trigger cannot produce the intended progress range.
• Missing physics world or body references: physics nodes reference a world or body that is not present.

Warning classes to review

• Pin spacing warnings may be acceptable only when another branch compensates for layout flow.
• Responsive gate and override warnings usually point to malformed conditions or invalid parameter paths.
• Density, sizing, and out-of-frame warnings should be reviewed on real page content and breakpoints.

Fix workflow

• Read the code, affected node ID, severity, and message.
• Find the node in the graph or source file.
• Fix the selector, port, parameter path, world/body reference, or responsive condition.
• Run validation again and compare the new result against the previous result.

Working sample slot

Validation errors and warning codes: This page reserves a sample location for a later verified example. Add the sample only after the source file, public page, validation output, and visual check all pass.
