// Regression guard for tests/_setup/isolateDataDir.ts — the test-only module that
|
|
// gives each test process its own DATA_DIR so concurrent test files never share the
|
|
// on-disk SQLite DB. Removing or breaking it brings back the cross-file state races
|
|
// (the `test:unit` hang under high concurrency and the non-deterministic Stryker
|
|
// baseline that forced concurrency: 1).
