Contributor guide
Research direction
Start in app/scripts/lib/stores/persistence-manager.ts around lines 77 and 714, then trace the storage.local access shown in the error. Compare the persistence failure with the block checksum mismatch from browser-polyfill.js:788. Done means identifying the corruption path and confirming a fix prevents or handles the missing vault data error.
