+  "_concurrency_comment": "concurrency=4 (was 1): the covering node:test files used to share SQLite/module state via the default DATA_DIR (~/.omniroute), so running them concurrently in the Stryker sandbox caused cross-file races that failed the all-green baseline. tap.nodeArgs now imports ./tests/_setup/isolateDataDir.ts, which gives each spawned test process its own temp DATA_DIR — eliminating the shared on-disk DB, so concurrency>1 is deterministic. A/B verified 2026-06-17: dry-run at concurrency=4 fails WITHOUT the isolation import (account-fallback-service tap exit 9) and passes WITH it. Raise further only if the runner has spare cores."
