JSSG (JS ast-grep) queries

JSSG codemod queries use JSSG for static analysis and custom metrics. Use them when you need programmatic logic, package-backed metrics, semantic analysis, or dimensions beyond a simple syntax match. The JSSG source can come from:

Inline source - write JSSG code directly in the editor.
A codemod package - select an existing JSSG codemod package from Codemod Registry.
A template variable - reuse a JSSG source defined at the dashboard level.

Configuration	Description
Source	Inline JSSG source, a JSSG codemod package, or a JSSG source template variable
Semantic mode	`Auto`, `Workspace`, or `File only` for supported JSSG sources
Select	`File count` or `Metric`
Metric	A named metric emitted by the JSSG source, with suggestions when Insights can extract them
Repository	One or more repositories, or a repository template variable
Group by	`repository`, `codeowner`, or metric cardinality keys
Dimension filters	Filter metric results by cardinality key-value pairs with equals, not-equals, or regex operators
File path filter	Include or exclude files using glob patterns
Snapshot base	A specific date or commit hash to analyze at a point in time, available for single number and table widgets
Query alias	A label for the query result, available for timeseries and table widgets

When a JSSG metric includes cardinality keys, table widgets can use those keys to break down results by the dimension that matters to the migration, such as component name, API name, package, or risk category.
