// Coverage for the advisory-only reconcile pass's URL decoding (scripts/reconcile-contracts.ts, PR
// #229). The pass is designed to NEVER fail the build. `fileUrlToPath` decodes NANO_APP_DB_URL, and a
// literal `%` (or any malformed %-escape) makes `decodeURIComponent` throw — which would crash an
// "advisory, never gate CI" script. Decoding is now best-effort, so a malformed URL degrades to the
// raw path instead of throwing.
