src/api A module — one directory, with the symbols and files in it

src/db The bar along the bottom is how much leans on it — files elsewhere that reference straight into it, against the most depended-on box here. The count is on the box

Depends on — the box above calls, imports, extends or names a type from the box below. Thicker is more references{declaredBasis ? '' : '; here the layering had too few imports to trust, so it used raw counts'}

Points back up — the lighter half of a mutual dependency, or a link with no import or declared type behind it. Drawn only while a module it touches is selected

top / bottom A module sits one layer above everything it depends on, so entry points end up at the top and the foundations — which depend on nothing below — at the bottom

src/api Selected: click a module to bring out its links and list its files; everything more than one hop away fades

nothing depends on this No link in the index arrives here — a script, a workflow, an unreferenced corner

__tests__ More than half its files are tests; off unless you turn tests on

gen Every file in it is tool-generated — nobody wrote it and nobody edits it

{thinCount} hidden Links carrying fewer than {minWeight} references wait until you select a module they touch, so a weak coincidence never draws as a dependency
