// Frontend functions over a cyclomatic-complexity limit, counted for scripts/audit_metrics.py: a bare
|
|
// `complexity` rule run (no type info, no other rules), so it takes seconds, not a full lint. Prints
|
|
// one JSON object: {"limit": N, "over": count, "max": highest}. Shipped code only — tests and test
|
|
// kits are lists of cases, not logic anyone has to change.
|

|
// node scripts/fe_complexity.mjs [limit] (default 20, the frontend's ratchet limit)
