The hash of empty content is a property of the content rather than of anything stored: every project's empty file has it, whether or not a blob was ever written under it, and a file may reference it before anything has. Eight blob stores were each paying a lookup -- a database query, an HTTP request, a read of a cache that offline mode may be the only thing standing in for -- to be told what the hash already says, and clsi had already reinvented the answer on its own. overleaf-editor-core gains BlobStoreBase, which answers getString for that hash and delegates the rest to the fetchString its subclasses provide. getObject comes with it: four stores spelled out the same JSON.parse of getString, and a fifth wrapped it in a log line. Adopted by history-v1's BlobStore, BackupBlobStore, HashCheckBlobStore and recover_zip's RecoveryBlobStore, by project-history's BlobStore, by clsi's BlobStore, and by web's HistoryBlobStore, SimpleBlobStore and FrontendBlobStore. history-v1 keeps its own answers in getStream, getBlob and getBlobs, which no other store implements. Writing and copying a blob are untouched, so a project that wrote empty content still has a blob for it and a read answers the same either way. Two paths could not handle a project holding a tracked change or a comment at all. Loading such a file needs the ranges blob its rangesHash points at, and hashing one again needs to write it back, so a store missing getObject or putObject fails outright: - recover_zip died on `blobStore.getObject is not a function`, making every such project unrecoverable. The test covering it asserts a tracked delete is absent from the zip, which the script already asked for and never reached. - GET /projects/:project_id/latest/hashed_content returned 500 from the same cause, then would have hit a missing putObject in snapshot.store. HashCheckBlobStore becomes a class over the base and gains putObject. Co-authored-by: Claude Opus 5 <noreply@anthropic.com> GitOrigin-RevId: c84f62465beff6cf77ffac26aa772984e1b554cb
